Over half of people who believed they were transgender, transitioned to the opposite sex, but then regretted it and transitioned back – known as detransitioners – felt they did not receive adequate evaluation from a doctor or mental health professional before starting transition, new research indicates.

In what is thought to be the first study to ask whether detransitioners informed their original clinicians of their regret at transitioning, only 24 of the 100 surveyed said they had done so.

This strongly suggests that records on detransition may understate the real numbers, said Lisa Littman, MD, MPH, president of The Institute for Comprehensive Gender Dysphoria Research (ICGDR), who is the sole author of the study, published in Archives of Sexual Behavior.

She stressed that the findings illustrate the complexity surrounding gender dysphoria. “We need to recognize that there are many different types of experiences around gender dysphoria, transition, and detransition,” she told this news organization.

She said there is some resistance among certain health care professionals, and in society in general, to the idea that transitioning is not always successful.
 

‘We need to understand why this is happening’

“Detransition exists and we need to understand why this is happening,” Dr. Littman emphasized.

She observed that some supporters of “rapid transition” do not want to accept that transitioning helps some individuals but harms others.

“In the end, our goals should be providing the right treatment for the right patient, and without a thorough evaluation, clinicians are at serious risk of giving patients the wrong treatment,” she urged.

She noted that, despite some individuals feeling better after transition, these people still felt inclined to detransition because of discrimination and pressure.

“Individuals should not be pressured to detransition, nor should they be pressured to transition. Both types of pressure were reported by respondents.” 

The recently recognized shift from mostly natal males to natal females seeking to transition was borne out by her study data, with the proportion of natal girls who detransitioned at 69%.
 

‘Shedding light’ on often ignored population

Asked to comment on the study, Laura Edwards-Leeper, PhD, a clinical psychologist from Beaverton, Ore., who specializes in gender-diverse and transgender children, welcomed Dr. Littman’s study.

It is, said Dr. Edwards-Leeper, a “critical preliminary step toward shedding light on this often-ignored and dismissed population of individuals who deserve support, compassion, and sometimes medical intervention from health care providers.”

She added that multiple online reports attest to detransitioners feeling they had not received adequate evaluation prior to medically transitioning, as well as many who expressed feeling too ashamed or angry to return to their same clinicians to detransition.

“Littman’s study provides quantitative support for both of these reported experiences, further emphasizing the importance of the field taking a closer look at the processes currently in place for those experiencing gender dysphoria,” said Dr. Edwards-Leeper.

And Miroslav L. Djordjevic, MD, PhD, professor of surgery/urology, University of Belgrade (Serbia), who is a specialist in urogenital reconstructive surgery and has performed over 2,000 gender-reassignment surgeries in transgender individuals, has recently seen many cases of regret after such surgeries, with requests for reversal operations.

“Despite the fact that medical detransition is relatively safe and without severe consequences, surgical detransition presents one of the most difficult issues in transgender medicine,” Dr. Djordjevic told this news organization.

Commending Dr. Littman on her study, he drew attention to some of the bioethical questions that arise relating to those who detransition.

“I ask what happened in the period before medical transitioning? Was there proper psychological care during medical transitioning? Who confirmed their desire for detransition – the same professionals who did the transition?” or someone else, he continued. “And who accepted these individuals for gender-affirming surgery and what were the criteria for this decision?”
 

Substantial study of reasons for both transitioning and detransitioning 

In her article, Dr. Littman describes a 100-strong population of individuals (66 Americans, 9 British, 9 Canadian, 4 Australians, and 12 from “other” nations), ranging in age from 18 years to over 60 years with a mean age of 29.2 years, who had experienced gender dysphoria, chosen to undergo medical and/or surgical transition, and then detransitioned by discontinuing medications, having reversal surgery, or both.

Participants completed a 115-question survey providing data including age at first experience of gender dysphoria, when participants first sought transitioning care and from whom, and whether they felt pressured to do so. Friendship group dynamics were also explored.

Various narratives of participants’ transitioning-detransitioning experiences were gathered and grouped, for example, those related to discrimination pressures, experiences of trauma or mental health conditions prior to transition, and reports of internalized homophobia.

Dr. Edwards-Leeper observed that the study offers a more extensive assessment of reasons for detransitioning than any other prior research in the field, which has been sparse.

A survey published in April found that detransitioners report significant unmet medical and psychological needs, and a lack of compassion and help from medical and mental health practitioners.

But another 2021 study concluded most detransitioners only reverted to their birth sex because of societal or family pressure, discrimination, or shift to a nonbinary identity.

“However, [Dr.] Littman’s study found that only a small percentage actually detransitioned for that reason [23%], whereas the majority detransitioned because of a change in how the individual understood being a male or female, resulting in becoming comfortable in their assigned gender [60%],” noted Dr. Edwards-Leeper.
 

Reasons for detransitioning

Asked to expand upon the motives for detransition identified in her study, Dr. Littman told this news organization: “We found remarkable breadth in the reasons given for detransitioning.” 

“I believe that we were able to capture the diversity of experiences around detransition because we reached out to communities that were strongly ‘protransition’ – like the World Professional Association for Transgender Health – and communities where individuals might be more skeptical about transition being universally beneficial, like detransition forums,” she said.

Speaking to the complexity of the experiences, 87% selected more than one reason for detransitioning.

The most common reason (60%) was becoming more comfortable identifying with their birth sex, followed by having concerns about potential medical complications from transitioning (49.0%).

Regarding those who became more comfortable with their natal sex, Dr. Littman noted that the finding adds “further support that gender dysphoria is not always permanent.”

She added that, “because most gender-dysphoric youth who are allowed to go through puberty grow up to be lesbian, gay, or bisexual (LGB) nontransgender adults, intervening too soon with medical treatments risks derailing their development as LGB individuals.”

Internalized homophobia or difficulty accepting themselves as lesbian, gay, or bisexual was reported by 23% of participants as a reason for transition and subsequent detransition. 

“For these people, transitioning could be interpreted as an attempt to escape the reality of being same-sex attracted and detransitioning was part of accepting themselves as homosexual or bisexual,” explained Dr. Littman.

“Exploring their distress and discomfort around sexual orientation issues may have been more helpful to them than medical and surgical transition or at least an important part of exploration,” she added in the article.
 

Societal pressure, friends, and social media also play a role

The latest first-hand reports also support prior work by Dr. Littman when she first identified the concept she termed rapid-onset gender dysphoria (ROGD) to describe a sudden transgender identification, usually in the early teenage years, and with no prior indication of any gender questioning.

ROGD, Dr. Littman believes, is strongly related to psychosocial factors, such as trauma, mental health problems, or social influence contributing to the development of gender dysphoria.

The current study found that 58% of respondents expressed the belief that the cause of their gender dysphoria was something specific, such as trauma, abuse, or a mental health condition, with respondents suggesting that transitioning prevented, or delayed, them from addressing their underlying mental health conditions. 

One participant is quoted as saying: “I was deeply uncomfortable with my secondary sex characteristics, which I now understand was a result of childhood trauma and associating my secondary sex characteristics with those events.”

Reflecting on their previous identification as transgender, more than a third of respondents reported that someone else told them their feelings meant they were transgender, and they believed them.

“This speaks to the effect social influence can have on people’s interpretation of their own feelings and their development of a transgender identity,” Dr. Littman remarked.

“Participants also listed several social media sources that encouraged them to believe that transitioning would help them,” she added.

Several friendship group dynamics suggestive of social influence were reported by a subset of respondents, including the fact that their friendship groups mocked people who were not transgender and their popularity increased when they announced they were going to transition. 
 

Pendulum has swung too far the other way

Natal females, who in recent years have made up most referrals, were younger than natal males when they sought transition and decided to detransition; and they stayed “transitioned” for a shorter period than natal males. They were also more likely to have experienced a trauma less than 1 year before the onset of gender dysphoria and were more likely to have felt pressured to transition. 

“Because the females in the study transitioned more recently than the males, they may have experienced a culture where there is more of a ‘push’ to transition,” Dr. Littman pointed out.

She added that, “20 years ago, gender-dysphoric patients were most likely to be underdiagnosed and undertreated. Now, the pendulum has swung the other way and patients are, in my opinion, more likely to be overdiagnosed and overtreated. I think we need to aim for somewhere between these two extremes and prioritize people getting the right treatment for the right reason for their distress.”

Dr. Djordjevic added that, with colleagues from Belgrade and the Netherlands, he has published accounts of the experiences of seven individuals who showed regret after gender-affirming surgery.

All of them were born male, “and we confirmed the very poor evaluation and transition process they underwent. We conclude that clinicians should be aware that not everyone with gender identity disorders need or want all elements of hormonal or surgical therapy,” he told this news organization.

Dr. Edwards-Leeper said that more long-term longitudinal studies are needed that follow individuals who undergo transition under different models of care.

“My prediction is that those who first engage in supportive, gender exploratory therapy, followed by comprehensive assessment, will have the best outcomes, perhaps even if they ultimately detransition, as these individuals will know that they did not jump into irreversible interventions too quickly and had time to make the best decision for themselves at the time,” she concluded.

A new position statement from the Royal Australian and New Zealand College of Psychiatrists (RANZCP) stresses the importance of a mental health evaluation for people with gender dysphoria – in particular for children and adolescents – before any firm decisions are made on whether to prescribe hormonal treatments to transition, or perform surgeries, often referred to as “gender-affirming care.”

“There is a paucity of quality evidence on the outcomes of those presenting with gender dysphoria. In particular, there is a need for better evidence in relation to outcomes for children and young people,” the guidance states.

Because gender dysphoria “is associated with significant distress ... each case should be assessed by a mental health professional, which will frequently be a psychiatrist, with the person at the center of care. It is important the psychological state and context in which gender dysphoria has arisen is explored to assess the most appropriate treatment,” it adds.

The move by the psychiatry body represents a big shift in the landscape regarding recommendations for the treatment of gender dysphoria in Australia and New Zealand.

Asked to explain the new RANZCP position, Philip Morris, MBBS, FRANZCP, said: “The College acknowledged the complexity of the issues and the legitimacy of different approaches.”

Exploration of a patient’s reasons for identifying as transgender is essential, he said in an interview, especially when it comes to young people.

“There may be other reasons for doing it, and we need to look for those, identify them and treat them. This needs to be done before initiating hormones and changing the whole physical nature of the child,” he said.

“A cautious psychotherapy-first approach makes sense. If we can do that with adolescents, then we will take a big step in the right direction,” stressed Dr. Morris, who is president of the National Association of Practising Psychiatrists in Australia.
 

Keira Bell case and Scandinavian stance lead to more open discussion

The rapid rise in gender dysphoria among adolescents in the Western world, referred to as “rapid-onset” or “late-onset” gender dysphoria, has seen a huge increase in the number of natal girls presenting and created frenzied debate that has intensified worldwide in the last 12 months about how to best treat youth with gender dysphoria.

Concerns have arisen that some transgender identification is due to social contagion, and there is a growing number of “detransitioners” – people who identified as transgender, transitioned to the opposite gender, but then regretted their decision, changed their minds, and “detransitioned” back to their birth sex. If they have had hormone therapy, and in some cases surgery, they are left with irreversible changes to their bodies.

As a result, Scandinavian countries, most notably Finland, once eager advocates of the gender-affirmative approach, have pulled back and issued new treatment guidelines in 2020 stating that psychotherapy, rather than gender reassignment, should be the first line of treatment for gender-dysphoric youth.

This, along with a landmark High Court decision in the U.K. regarding the use of puberty-blocking drugs for children with gender dysphoria, brought by detransitioner Keira Bell, which was recently overturned by the Appeal Court, but which Ms. Bell now says she will take to the Supreme Court, has led to a considerable shift in the conversation around treating transgender adolescents with hormonal therapy, says Dr. Morris.

At odds with prior Australian recommendations

The RANZCP had previously endorsed the standard guidelines of the Royal Children’s Hospital (RCH) Melbourne, followed by most gender-identity services in Australia and similar guidance from New Zealand, which both recommend gender-affirming care.

“Increasing evidence demonstrates that with supportive, gender-affirming care during childhood and adolescence, harms can be ameliorated and mental health and well-being outcomes can be significantly improved,” state the RCH guidelines.

But in 2019, RANZCP removed its endorsement of the RCH guidelines and started a consultation, which resulted in the new position statement.

However, Ken Pang, MD, of the Murdoch Children’s Research Institute in Melbourne and an author of the RCH guidelines, says the key recommendations of the new RANZCP position statement are consistent with their own guidelines.

The former note “the need for a skilled mental health clinician in providing comprehensive exploration of a child or adolescent’s biopsychosocial context,” Dr. Pang says.

However, it’s difficult not to see the contrast in stance when the new RANZCP statement maintains: “Research on gender dysphoria is still emerging. There are polarized views and mixed evidence regarding treatment options for people presenting with gender identity concerns, especially children and young people.”

Dr. Pang says the RCH guidelines do, however, recognize the need for further research in the field.

“I look forward to being able to incorporate such research, including from our own Trans20 study, into future revisions of our guidelines,” he told this news organization.
 

Watch your backs with affirmative therapy: Will there be a compromise?

Dr. Morris says there will obviously be cases where “the child might transition with a medical intervention, but that wouldn’t be the first step.”

And yet, he adds, “There are those who push the pro-trans view that everyone should be allowed to transition, and the doctors are only technicians that provide hormones with no questions asked.” 

But from a doctor’s perspective, clinicians will still be held responsible in medical and legal terms for the treatments given, he stressed.

“I don’t think they will ever not be accountable for that. They will always need to determine in their own mind whether their actions have positive value that outweigh any disadvantages,” Dr. Morris continues.

The RANZCP statement does, in fact, stress just this.

All health care professionals need to “be aware of ethical and medicolegal dilemmas” pertaining to affirmative therapy, it indicates. “Psychiatrists should practice within the relevant laws and accepted professional standards in relation to assessing capacity and obtaining consent...”

Dr. Morris hopes there will ultimately be many more checks and balances in place and that courts and clinicians will need to step back and not assume every child who seeks to transition is doing it as a result of pure gender dysphoria.

He predicts that things will end in a compromise. 

“In my view, this compromise will treat children with respect and approach them like any other patient that presents with a condition that requires proper assessment and treatment.”

“In the end, some cases will be transitioned, but there will be fewer than [are] transitioned at the moment,” he predicts.

Dr. Morris has reported no relevant financial relationships. Dr. Pang is a member of the Australian Professional Association for Trans Health and its research committee.

A new position statement from the Royal Australian and New Zealand College of Psychiatrists (RANZCP) stresses the importance of a mental health evaluation for people with gender dysphoria – in particular for children and adolescents – before any firm decisions are made on whether to prescribe hormonal treatments to transition, or perform surgeries, often referred to as “gender-affirming care.”

“There is a paucity of quality evidence on the outcomes of those presenting with gender dysphoria. In particular, there is a need for better evidence in relation to outcomes for children and young people,” the guidance states.

Because gender dysphoria “is associated with significant distress ... each case should be assessed by a mental health professional, which will frequently be a psychiatrist, with the person at the center of care. It is important the psychological state and context in which gender dysphoria has arisen is explored to assess the most appropriate treatment,” it adds.

The move by the psychiatry body represents a big shift in the landscape regarding recommendations for the treatment of gender dysphoria in Australia and New Zealand.

Asked to explain the new RANZCP position, Philip Morris, MBBS, FRANZCP, said: “The College acknowledged the complexity of the issues and the legitimacy of different approaches.”

Exploration of a patient’s reasons for identifying as transgender is essential, he said in an interview, especially when it comes to young people.

“There may be other reasons for doing it, and we need to look for those, identify them and treat them. This needs to be done before initiating hormones and changing the whole physical nature of the child,” he said.

“A cautious psychotherapy-first approach makes sense. If we can do that with adolescents, then we will take a big step in the right direction,” stressed Dr. Morris, who is president of the National Association of Practising Psychiatrists in Australia.
 

Keira Bell case and Scandinavian stance lead to more open discussion

The rapid rise in gender dysphoria among adolescents in the Western world, referred to as “rapid-onset” or “late-onset” gender dysphoria, has seen a huge increase in the number of natal girls presenting and created frenzied debate that has intensified worldwide in the last 12 months about how to best treat youth with gender dysphoria.

Concerns have arisen that some transgender identification is due to social contagion, and there is a growing number of “detransitioners” – people who identified as transgender, transitioned to the opposite gender, but then regretted their decision, changed their minds, and “detransitioned” back to their birth sex. If they have had hormone therapy, and in some cases surgery, they are left with irreversible changes to their bodies.

As a result, Scandinavian countries, most notably Finland, once eager advocates of the gender-affirmative approach, have pulled back and issued new treatment guidelines in 2020 stating that psychotherapy, rather than gender reassignment, should be the first line of treatment for gender-dysphoric youth.

This, along with a landmark High Court decision in the U.K. regarding the use of puberty-blocking drugs for children with gender dysphoria, brought by detransitioner Keira Bell, which was recently overturned by the Appeal Court, but which Ms. Bell now says she will take to the Supreme Court, has led to a considerable shift in the conversation around treating transgender adolescents with hormonal therapy, says Dr. Morris.

“This [has moved from] ... a topic that could previously not be talked about freely to one that we can discuss more openly now. This is a big improvement. Previously, everyone thought it was all settled, but it’s not, certainly not from a medical angle,” he states.

Mortality is consistently twice as high in transgender people receiving hormone treatment, compared with cisgender individuals in the general population and has not decreased over time, results of a 5 decades–long study from the Netherlands indicate.

Particularly concerning is that trans women (male to female) had a mortality risk nearly double that of cis men (born and remain male) in the general Dutch population (standardized mortality ratio, 1.8), while it was nearly triple that of cis women (SMR, 2.8).

Compared with cisgender women, transgender women were more than twice as likely to die from heart disease, three times more likely to die from lung cancer, and almost nine times more likely to die from infection. HIV-related disease mortality risk was nearly 50 times higher for trans women than cis women, and the risk of suicide was almost seven times greater.  

Suicide and other nonnatural causes of death were more common in trans men, compared with cis women.

The report, by Christel J.M. de Blok, MD, of Amsterdam University Medical Center and colleagues, was published online Sept. 2 in The Lancet Diabetes & Endocrinology.

The study included trans men who received testosterone to transition from female to male and trans women who received estrogen plus an antiandrogen to transition from male to female.
 

Is gender-affirming hormone therapy associated with increased mortality?

Senior author Martin den Heijer, MD, also of Amsterdam University Medical Center, said: “The findings of our large, nationwide study highlight a substantially increased mortality risk among transgender people that has persisted for decades.”

But he pointed out that, overall, the data do not appear to suggest the premature deaths were related to gender-affirming hormone treatment.

However, he conceded that more work is needed on this aspect of care. “There is insufficient evidence at present to determine long-term safety of [gender-affirming hormone treatment]. More research is needed to fully establish whether it in any way affects mortality risk for transgender people,” said Dr. den Heijer.

Endocrinologist Will Malone, MD, of Twin Falls, Idaho, told this news organization, “The study confirms, like others before it, that individuals taking cross-sex hormones are more likely to die prematurely from a number of causes.”

“While the authors speculate that this higher mortality rate is not connected to cross-sex hormones, the study was not designed to be able to make such a claim,” he said, pointing to limited follow-up times. 

In an accompanying commentary, Vin Tangpricha, MD, PhD, an endocrinologist from Emory University, Atlanta, noted: “Transgender men do not appear to have as significantly increased comorbidity following receipt of gender-affirming hormone therapy when compared with transgender women.”

Dr. Tangpricha added future studies should examine which factors – hormone regimen, hormone concentrations, access to health care, or other biological factors – explain the higher increased risk of morbidity and mortality observed in trans women as opposed to trans men.

However, Dr. de Blok and colleagues note that, as there were relatively few deaths among transgender men in the cohort, analysis on cause of death in this group is limited.

Transgender individuals more likely to die younger

For their study, Dutch researchers retrospectively examined data from 4,568 transgender people attending their clinic (2,927 transgender women and 1,641 transgender men) treated in 1972-2018. People were excluded if they started treatment before the age of 17 or if they had received puberty-blocking drugs.

Data on age at start of hormone treatment, type of treatment, smoking habits, medical history, and last date of follow-up were gathered from medical records. Where possible, SMRs were determined for deaths among trans men and trans women, compared with rates for the adult Dutch general population.

Median age at the start of cross-sex hormone treatment was 30 years in transgender women and 23 years in transgender men. But the median follow-up time was only 11 years in transgender women and 5 years in transgender men.

A total of 317 (10.8%) trans women died, and 44 (2.7%) trans men died. The findings were higher than expected, compared with the general population of cisgender women (SMR, 1.8) but not cisgender men (SMR 1.2).

Mortality risk did increase more in transgender people who started gender-affirming hormone treatment in the past 2 decades compared with earlier, a fact that Dr. de Blok said was surprising.

Trans men, for example, compared with cis women, had an SMR of 2.1-2.4 in 2000-2018 (compared with 1.8 overall).

“This may be due to changes in clinical practice. ... In the past, health care providers were reluctant to provide hormone treatment to people with a history of comorbidities such as cardiovascular disease. However, because of the many benefits of enabling people to access hormone therapy, nowadays this rarely results in treatment being denied,” Dr. de Blok noted.
 

More research needed, especially in trans-identifying youth

Dr. Malone remarked that previous studies have shown associations between taking cross-sex hormones and elevated mortality, while also “not designed to detect causality,” have “generally accepted that natal males who take estrogen have estrogen-related increases in the rates of heart disease, stroke, and deep venous thrombosis.” 

He added that the risks of testosterone use in natal females were less well established, “but testosterone is also felt to increase their risk of heart disease.” 

He stressed the limited follow-up times in the study by Dr. de Blok and colleagues.

This “strongly suggests that the rate of elevated mortality far exceeds the doubling measured by the study, especially for natal females.”

Dr. Malone is one of several clinicians and researchers who has formed the Society for Evidence-Based Gender Medicine, a nonprofit organization that now has at least 100 physician members. SEGM is concerned about the lack of quality evidence for the use of hormonal and surgical interventions as first-line treatment, especially for young people with gender dysphoria.  

Dr. Tangpricha also highlighted that the findings do not apply to transgender people who began treatment before age 17 years or those who had taken puberty blockers before gender-affirming hormone treatment.

There are no long-term data on transgender individuals who have received gender-affirming hormone therapies close to the time of puberty.

These data, such as those from the Trans Youth Care study, should be available in the future, he added.

The authors have reported no relevant financial relationships. Dr. Tangpricha has reported receiving funding from the National Institutes of Health and served as past president of the World Professional Association for Transgender Health. He is editor-in-chief of Endocrine Practice and has provided expert testimony for Kirkland and Ellis.

Dr. Malone remarked that previous studies have shown associations between taking cross-sex hormones and elevated mortality, while also “not designed to detect causality,” have “generally accepted that natal males who take estrogen have estrogen-related increases in the rates of heart disease, stroke, and deep venous thrombosis.” 

He added that the risks of testosterone use in natal females were less well established, “but testosterone is also felt to increase their risk of heart disease.” 

He stressed the limited follow-up times in the study by Dr. de Blok and colleagues.

This “strongly suggests that the rate of elevated mortality far exceeds the doubling measured by the study, especially for natal females.”

Dr. Malone is one of several clinicians and researchers who has formed the Society for Evidence-Based Gender Medicine, a nonprofit organization that now has at least 100 physician members. SEGM is concerned about the lack of quality evidence for the use of hormonal and surgical interventions as first-line treatment, especially for young people with gender dysphoria.  

Dr. Tangpricha also highlighted that the findings do not apply to transgender people who began treatment before age 17 years or those who had taken puberty blockers before gender-affirming hormone treatment.

There are no long-term data on transgender individuals who have received gender-affirming hormone therapies close to the time of puberty.

These data, such as those from the Trans Youth Care study, should be available in the future, he added.

The authors have reported no relevant financial relationships. Dr. Tangpricha has reported receiving funding from the National Institutes of Health and served as past president of the World Professional Association for Transgender Health. He is editor-in-chief of Endocrine Practice and has provided expert testimony for Kirkland and Ellis.

Clinicians should not blindly accept a person’s self-diagnosis as transgender and desire to medically transition without closer inspection; rather, they should make a distinction between ‘acceptance’ and conducting an in-depth, respectful, and collaborative exploration of an individual’s claims about what they believe will best promote their well-being.

These are the conclusions of two experts in ethics and clinical psychology in an extended essay published in the Journal of Medical Ethics.

“It’s not about making life harder for people who wish to transition but about improving care for all people who identify as transgender,” lead author Alessandra Lemma, DClin Psych, visiting professor in the psychoanalysis unit at University College London, said in an interview.

She stressed that the argument is neither for nor against medical transitioning per se.

“It’s an invitation to think about how the medical and mental health care communities can best support anyone considering a transition, whether they eventually pursue that course of action or not. The provision of psychotherapy, irrespective of whether the individual medically transitions or not, makes for a better outcome either way,” said Dr. Lemma, who cares for adolescents as well as adults with gender dysphoria in her private practice in London.  
 

Reflective space has been eroded in gender identity services for the young

There has been an exponential increase in the number of adolescents who identify as transgender in Western countries in recent years. This news organization has covered the debate in detail, which has intensified worldwide in the last 12 months, regarding how best to treat youth with gender dysphoria.

This has “raised concern about how the laudable aims of gender affirmative care may be ushering children and young people too quickly into medical transitioning,” generally defined as treatment with puberty blockers in minors followed by cross-sex hormones to transition to the opposite sex, “leading subsequently to a wish to detransition with all the attendant physical and psychological complications,” wrote Dr. Lemma and her coauthor, Julian Savulescu, MD, professor of practical ethics, University of Oxford (England).

While the United Kingdom and other countries such as Finland have tightened regulations regarding the treatment of minors, “these medical interventions continue to be provided in many other countries,” they noted.

Such affirmative care has recently been interpreted by “influential sections of the transgender community” as forbidding “’questioning’ of any kind of the person’s stated gender and what will help them,” the essayists stated.

But Dr. Lemma noted that, for teenagers, this is typically a time to “try on” different identities and ways of presenting oneself to the world.

“All this requires a reflective space during the decision-making process, and this has been eroded in many gender identity services for young people especially, with a massive pressure on services.”

Family issues, trauma, and comorbid conditions can all influence people too, she noted, adding that what may be happening unconsciously may be driving the decision to modify the body.

“I cannot see that it would be harmful to anyone to have the opportunity to really think about what they are doing before making decisions about medical interventions,” she asserted.
 

Decision to transition must be judged to be autonomous

Dr. Lemma noted that even in those instances where medical transitioning, on balance, is the best option, it’s important to acknowledge that the process has a psychological impact.

“What matters is that in facing a major life-changing decision, an individual has the opportunity to understand the developmental and social experiences that drive their experience of gender dysphoria such that the decisions they make about medical transitioning can be said to be taken more autonomously,” she and Dr. Savulescu wrote.

And for those people who opt for full gender reassignment surgery, they are the first to say, “I don’t think I could have got through this as well as I have without psychological support,” Dr. Lemma remarked.

Ultimately, what’s important is to ensure the protection of those individuals whose needs will most likely not be met by medical transitioning, while not making it impossible for those who are suffering to get the care they need in order to transition, she concluded. 

Until 2016, Dr. Lemma was professor of psychological therapies at the Tavistock and Portman NHS Foundation Trust and Essex University. During that time she worked with adult transgender individuals at the Portman clinic but not at the Gender Identity Service at the Tavistock clinic. Currently, she works in private practice with transgender individuals at the Queen Anne Street Practice, London. Dr. Savulescu has reported no relevant financial relationships.

The contraceptive needs of women who have had in vitro fertilization (IVF) pregnancies are real but are being overlooked, according to study data presented at the Royal College of Obstetricians & Gynaecologists (RCOG) Virtual World Congress 2021.

The interview-based study found that women report not being routinely informed about the chance of spontaneous pregnancy after IVF. “There is scope to follow-up with women after IVF … but information about the chances of spontaneous births and need for contraception isn’t given,” said lead researcher Annette Thwaites, MD, an academic clinical fellow and a senior registrar in Community Sexual and Reproductive Health at Kings College Hospital, London.

“Fertility services, maternity services, and community services could all do more to give women information on contraception postnatally,” Dr. Thwaites said.

“Even if a woman has had IVF previously, a woman shouldn’t lose the right to plan the rest of her family,” she added. “We need to stop shielding these women from the information they really do need.”

Dr. Thwaites first came across the issue around contraception after IVF pregnancy while talking to new mothers in a postnatal ward for another study. Ward staff told her not to enter the rooms with women who had had IVF births, with the implication that these women would not need or want contraception.

With this in mind, Dr. Thwaites and colleagues aimed to better understand the contraceptive needs of women after successful IVF pregnancy to improve service delivery and prevent unplanned and rapid-repeat pregnancies after IVF.

The researchers interviewed 21 women who had spontaneous pregnancies after successful IVF. Participants were aged 35-50 years, the majority were White, British, professional, married for at least 10 years, and living in nuclear families.

Of the spontaneous post-IVF pregnancies in these women, outcomes included single (11) and multiple live births (1 twin), miscarriage (1), ectopic (1) termination of pregnancy (1), and three ongoing pregnancies.  

After IVF pregnancy, most women said that they used no contraception or ineffective contraception and had never had a conversation around contraception after IVF.

The women also reported that spontaneous pregnancy was shocking and not universally welcomed, and interpregnancy intervals were often short.

In addition, comments by these women suggested certain aspects of the IVF experience reinforced their perceptions of subfertility. One is quoted as saying, “It seemed to be this big failure if you were having IVF.” Another said, “It’s bad enough that I’m having to conceive my baby like this.”
 

An unmet need

In her 30 years of practice, Melanie Davies, MD, has seen many women who experience natural pregnancy after IVF. She agrees it is important to address these women’s contraceptive needs but stresses that it needs to be approached carefully.

“It can stir up sensitivities to discuss this issue after having an IVF pregnancy,” said Dr. Davies, a consultant obstetrician and gynecologist at University College London Hospitals, London. “I think many women genuinely think that contraception after IVF just doesn’t apply, but lots of women do have natural pregnancies after IVF. I think women do need this information, but we need to be aware of the sensitivities around this issue, so the way we deliver it is crucial.”

Gwenda Burns, chief executive of the National Patient Charity Fertility Network UK, which supports people before, during, and after fertility treatment, agrees that the process leading up to a successful IVF birth can have lasting effects.

“Fertility struggles and going through fertility treatment can put an enormous strain on both physical and mental health and can have a long-lasting impact,” Ms. Burns said when asked to comment on the new study.

“It is vital that patients receive the right support, guidance, and advice following treatment, including when natural conception may still be possible,” Ms. Burns continued.
 

Growing population

Given the increasing use of IVF in recent years, Dr. Thwaites said the importance of understanding and meeting the contraceptive needs of women post-IVF is increasingly important. Also, people are turning to it earlier and for other reasons, such as women in same sex relationships, single women, pre-implantation genetic testing, and surrogates.

“During the recruitment process for the current study, I came across women who said since their IVF pregnancies they had no idea what they should do about contraception,” Dr. Thwaites said.

But she empathizes with health care professionals too. “I genuinely feel that health care professionals just don’t know how to advise women in this setting, so they avoid the topic of contraception altogether with these women. They are concerned about making women feel awkward or upsetting them. In my experience, there is very little said about IVF and contraception in the same breath.”
 

Women believe subfertility always persists after IVF

Among participants in the study, the causes of the women’s subfertility were wide-ranging and included tubal, anovulatory, male factor, joint, and unexplained, the latter of which affects 25% of couples with fertility issues. In the cohort, women had taken up to 9 years to conceive their first child and one had a donor egg conception.

After IVF, the chance of pregnancy will depend on the reason for the couple’s subfertility. “Given that a huge number of patients these days have unexplained subfertility. This is when there is no absolute cause of infertility identified, and it might not prevent a pregnancy but slows it down,” Dr. Davies said in an interview. “Such couples still have a chance of natural pregnancy.”

Polycystic ovary syndrome as a cause of subfertility is often associated with improvement in fertility after IVF, Dr. Davies noted. “This can improve after a spontaneous pregnancy or after IVF, even if the IVF is not a success, and this is possibly due to needling the ovary.”

Dr. Thwaites added that challenging women’s perceptions of their subfertility is critical if headway is to be made on this topic. Many women have persistent views concerning their subfertility after successful IVF, which may be rooted in previous failed treatment; need for repeat cycles or intracytoplasmic sperm injection (ICSI); low numbers of eggs collected; poor quality embryos; and pregnancy complications, to note some of the most common reasons.

“So many [women] feel that they are very lucky to have had a pregnancy because their journey has been difficult. They might have had a successful pregnancy, but they still hold a sense of personal failure,” said Dr. Thwaites. “Even after spontaneous pregnancy some women said it was a miracle or freak event. [Yet two of these] women had two spontaneous pregnancies.”

Remarkably, even after subsequent spontaneous pregnancy, use of contraception and the most effective methods remained low among participants.

As well as fixed beliefs concerning their subfertility, other barriers to contraception use included a lack of knowledge of likelihood of spontaneous pregnancy; lack of contraceptive experience; and inherent incentives towards shorter interpregnancy intervals (e.g., the convenience and privacy of undergoing further IVF while still on maternity leave and availability of frozen embryos).

Looking ahead, Dr. Thwaites says there is a clear need to link and/or expand the maternity services dataset to uncover the true rates of post-IVF spontaneous pregnancy.

Dr. Thwaites and Dr. Davies have disclosed no relevant financial relationships.

Looking ahead, Dr. Thwaites says there is a clear need to link and/or expand the maternity services dataset to uncover the true rates of post-IVF spontaneous pregnancy.

Dr. Thwaites and Dr. Davies have disclosed no relevant financial relationships.

Young people with gender dysphoria should be considered as individuals rather than fall into an age-defined bracket when assessing their understanding to consent to hormone treatment, according to the Tavistock and Portman NHS Foundation Trust, as it awaits the verdict of its recent appeal in London against a High Court ruling. 

The High Court ruling, made in December 2020 as reported by this news organization, stated that adolescents with gender dysphoria were unlikely to fully understand the consequences of hormone treatment for gender reassignment and was the result of a case brought by 24-year-old Keira Bell, who transitioned from female to male at the Gender Identity Development Service (GIDS), starting at the age of 16, but later “detransitioned.”

Along with changes made to rules around prescribing puberty blockers and cross-sex hormones to minors with gender dysphoria in countries such as Finland and Sweden, the English ruling signals a more cautious approach to any medical treatment for such children, as detailed in a feature published in April.

However, during the appeal, The Trust argued once more that puberty blockers give children time to “consider options” about their bodies and that the decision (the December ruling) was inconsistent with the law that “entitles children under the age of 16 to make decisions for themselves after being assessed as competent to do so by their doctor.”

Alongside other organizations, the United States–based Endocrine Society submitted written evidence in support of the Tavistock. “The High Court’s decision, if it is allowed to stand, would set a harmful precedent preventing physicians from providing transgender and gender diverse youth with high-quality medical care,” it noted in a statement.

Defending the High Court’s ruling, the lawyer for Ms. Bell said its conclusion was that puberty blockers for gender dysphoria are an “experimental” treatment with a very limited evidence base.

“The judgment of the [High Court] is entirely correct, and there is no proper basis for overturning it,” he asserted.

The 2-day appeal hearing ended on June 24, and a ruling will be made at a later date.
 

Do children understand the consequences of hormone treatment?

One central aspect of the overall case is the fact that Ms. Bell regrets her decision to transition at age 16, saying she only received three counseling sessions prior to endocrinology referral. And she consequently had a mastectomy at age 20, which she also bitterly regrets.

So a key concern is whether young people fully understand the consequences of taking puberty blockers and therapies that may follow, including cross-sex hormones.

Witness for the appeal Gary Butler, MD, consultant in pediatric and adolescent endocrinology at University College Hospital, London, where children are referred to from GIDS for hormone treatment, said the number of children who go on to cross-sex hormones from puberty blockers is “over 80%.” 

But the actual number of children who are referred to endocrinology services (where puberty blockers are initiated) from GIDS is low, at approximately 16%, according to 2019-2020 data, said a GIDS spokesperson.

“Once at the endocrinology service, young people either participate in a group education session, or if under 15 years, an individualized session between the clinician and the patient and family members,” she added. The Trust also maintained that initiation of cross-sex hormones “is separate from the prescription of puberty blockers.”

Since the December ruling, The Trust has put in place multidisciplinary clinical reviews (MDCR) of cases, and in July, NHS England will start implementing an independent multidisciplinary professional review (MDPR) to check that the GIDS has followed due process with each case.
 

Slow the process down, give appropriate psychotherapy

Stella O’Malley is a psychotherapist who works with transitioners and detransitioners and is a founding member of the International Association of Therapists for Desisters and Detransitioners (IATDD).

Whatever the outcome of the appeal process, Ms. O’Malley said she would like to see the Tavistock slow down and take a broader approach to counseling children before referral to endocrinology services. 

In discussing therapy prior to transition, Ms. O’Malley stated that her clients often say they did not explore their inner motivations or other possible reasons for their distress, and the therapy was focused more on when they transition, rather than being sure it was something they wanted to do.

“We need to learn from the mistakes made with people like Keira Bell. Clinicians need to realize that fast-tracking counseling doesn’t work, especially when [children are] ... young and especially when they’re traumatized,” Ms. O’Malley said.

“Had they received a more conventional therapy, they might have thought about their decision from different perspectives and in the process acquired more self-awareness, which would have been more beneficial.” 

“The ‘affirmative’ approach to gender therapy is too narrow; we need to look at the whole individual. Therapy in other areas would never disregard other, nongender issues such as attention deficit hyperactivity disorder or anxiety [which often co-exist with gender dysphoria] – issues bleed into each other,” Ms. O’Malley pointed out. “We need a more exploratory approach.”  

“I’d also like to see other therapists all over the [U.K.] who are perfectly qualified and capable of working with gender actually start working with gender issues,” she said, noting that such an approach might also help reduce the long waiting list at the Tavistock.

The latter had been overwhelmed, and this led to a speeding up of the assessment process, which led to a number of professionals resigning from the service in recent years, saying children were being “fast-tracked” to medical transition.  
 

Fertility and sexual function are complex issues for kids

Also asked to comment was Claire Graham, from Genspect, a group that describes itself as a voice for parents of gender-questioning kids.

She told this news organization that “parents are rightly concerned about their children’s ability to consent to treatments that may lead to infertility and issues surrounding sexual function.” She added that other countries in Europe were changing their approach. “Look to Sweden and Finland, who have both rowed back on puberty blockers and no longer recommend them.”

Ms. Graham, who has worked with children with differences in sexual development, added that it was very difficult for children and young people to understand the life-long implications of decisions made at an early age.

“How can children understand what it is to live with impaired sexual functioning if they have never had sex? Likewise, fertility is a complex issue. Most people do not want to become parents as teenagers, but we understand that this will often change as they grow,” said Ms. Graham.

“Many parents worry that their child is not being considered in the whole [and] that their child’s ability to consent to medical interventions for gender dysphoria is impacted by comorbidities, such as a diagnosis of autism or a history of mental health issues. These children are particularly vulnerable.”

“At Genspect, we hope that the decision from the ... court is upheld,” Ms. Graham concluded.

Pregnant women with a history of bariatric surgery have better cardiovascular adaptation to pregnancy compared with women who have similar early-pregnancy body mass index (BMI) but no history of weight loss surgery, new data suggest.

“Pregnant women who have had bariatric surgery demonstrate better cardiovascular adaptation through lower blood pressure, heart rate, and cardiac output, more favorable diastolic indices, and better systolic function,” reported Deesha Patel, MBBS MRCOG, specialist registrar, Chelsea and Westminster Hospital, London.

“Because the groups were matched for early pregnancy BMI, it’s unlikely that the results are due to weight loss alone but indicate that the metabolic alterations as a result of the surgery, via the enterocardiac axis, play an important role,” Dr. Patel continued.

The findings were presented at the Royal College of Obstetricians and Gynecologists 2021 Virtual World Congress.

Although obesity is known for its inflammatory and toxic effects on the cardiovascular system, it is not clear to what extent the various treatment options for obesity modify these risks in the long term, said Hutan Ashrafian, MD, clinical lecturer in surgery, Imperial College London.

“It is even less clear how anti-obesity interventions affect the cardiovascular system in pregnancy,” Dr. Ashrafian told this news organization.

“This very novel study in pregnant mothers having undergone the most successful and consistent intervention for severe obesity – bariatric or metabolic surgery – gives new clues as to the extent that bariatric procedures can alter cardiovascular risk in pregnant mothers,” continued Dr. Ashrafian, who was not involved in the study.

The results show how bariatric surgery has favorable effects on cardiac adaptation in pregnancy and in turn “might offer protection from pregnancy-related cardiovascular pathology such as preeclampsia,” explained Dr. Ashrafian. “This adds to the known effects of cardiovascular protection of bariatric surgery through the enterocardiac axis, which may explain a wider range of effects that can be translated within pregnancy and possibly following pregnancy in the postpartum era and beyond.”
 

A history of bariatric surgery versus no surgery

The prospective, longitudinal study compared 41 women who had a history of bariatric surgery with 41 women who had not undergone surgery. Patients’ characteristics were closely matched for age, BMI (34.5 kg/m2 and 34.3 kg/m2 in the surgery and bariatric surgery groups, respectively) and race. Hypertensive disorders in the post-surgery group were significantly less common compared with the no-surgery group (0% vs. 9.8%).

During the study, participants underwent cardiovascular assessment at 12-14 weeks, 20-24 weeks, and 30-32 weeks of gestation. The assessment included measurement of blood pressure and heart rate, transthoracic echocardiography, and 2D speckle tracking, performed offline to assess global longitudinal and circumferential strain.

Blood pressure readings across the three trimesters were consistently lower in the women who had undergone bariatric surgery compared with those in the no-surgery group, and all differences were statistically significant. Likewise, heart rate and cardiac output across the three trimesters were lower in the post-surgery cohort. However, there was no difference in stroke volume between the two groups.

As for diastolic function, there were more favorable indices in the post-surgery group with a higher E/A ratio, a marker of left ventricle filling (P < .001), and lower left atrial volume (P < .05), Dr. Patel reported.

With respect to systolic function, there was no difference in ejection fraction, but there was lower global longitudinal strain (P < .01) and global circumferential strain in the post-bariatric group (P = .02), suggesting better systolic function.

“Strain is a measure of differences in motion and velocity between regions of the myocardium through the cardiac cycle and can detect subclinical changes when ejection fraction is normal,” she added.

“This is a fascinating piece of work. The author should be congratulated on gathering so many [pregnant] women who had had bariatric surgery. The work gives a unique glimpse into metabolic syndrome,” said Philip Toozs-Hobson, MD, who moderated the session.

“We are increasingly recognizing the impact [of bariatric surgery] on metabolic syndrome, and the fact that this study demonstrates that there is more to it than just weight is important,” continued Dr. Toosz-Hobson, who is a consultant gynecologist at Birmingham Women’s Hospital NHS Foundation Trust, United Kingdom.
 

Cardiovascular benefits of bariatric surgery

Bariatric surgery has been associated with loss of excess body weight of up to 55% and with approximately 40% reduction in all-cause mortality in the general population. The procedure also reduces the risk for heart disease, diabetes, and cancer.

The cardiovascular benefits of bariatric surgery include reduced hypertension, remodeling of the heart with a reduction in left ventricular mass, and an improvement in diastolic and systolic function.

“Traditionally, the cardiac changes were thought to be due to weight loss and blood pressure reduction, but it is now conceivable that the metabolic components contribute to the reverse modeling via changes to the enterocardiac axis involving changes to gut hormones,” said Dr. Patel. These hormones include secretin, glucagon, and vasoactive intestinal peptide, which are known to have inotropic effects, as well as adiponectin and leptin, which are known to have cardiac effects, she added.

“Pregnancy following bariatric surgery is associated with a reduced risk of hypertensive disorders, as well as a reduced risk of gestational diabetes, large-for-gestational-age neonates, and a small increased risk of small-for-gestational-age neonates,” said Dr. Patel.

Dr. Patel and Dr. Toosz-Hobson have disclosed no relevant financial relationships.

As for diastolic function, there were more favorable indices in the post-surgery group with a higher E/A ratio, a marker of left ventricle filling (P < .001), and lower left atrial volume (P < .05), Dr. Patel reported.

With respect to systolic function, there was no difference in ejection fraction, but there was lower global longitudinal strain (P < .01) and global circumferential strain in the post-bariatric group (P = .02), suggesting better systolic function.

“Strain is a measure of differences in motion and velocity between regions of the myocardium through the cardiac cycle and can detect subclinical changes when ejection fraction is normal,” she added.

“This is a fascinating piece of work. The author should be congratulated on gathering so many [pregnant] women who had had bariatric surgery. The work gives a unique glimpse into metabolic syndrome,” said Philip Toozs-Hobson, MD, who moderated the session.

“We are increasingly recognizing the impact [of bariatric surgery] on metabolic syndrome, and the fact that this study demonstrates that there is more to it than just weight is important,” continued Dr. Toosz-Hobson, who is a consultant gynecologist at Birmingham Women’s Hospital NHS Foundation Trust, United Kingdom.
 

Cardiovascular benefits of bariatric surgery

Bariatric surgery has been associated with loss of excess body weight of up to 55% and with approximately 40% reduction in all-cause mortality in the general population. The procedure also reduces the risk for heart disease, diabetes, and cancer.

The cardiovascular benefits of bariatric surgery include reduced hypertension, remodeling of the heart with a reduction in left ventricular mass, and an improvement in diastolic and systolic function.

“Traditionally, the cardiac changes were thought to be due to weight loss and blood pressure reduction, but it is now conceivable that the metabolic components contribute to the reverse modeling via changes to the enterocardiac axis involving changes to gut hormones,” said Dr. Patel. These hormones include secretin, glucagon, and vasoactive intestinal peptide, which are known to have inotropic effects, as well as adiponectin and leptin, which are known to have cardiac effects, she added.

“Pregnancy following bariatric surgery is associated with a reduced risk of hypertensive disorders, as well as a reduced risk of gestational diabetes, large-for-gestational-age neonates, and a small increased risk of small-for-gestational-age neonates,” said Dr. Patel.

Dr. Patel and Dr. Toosz-Hobson have disclosed no relevant financial relationships.

Diaphragmatic endometriosis is often diagnosed several years after the start of symptoms – mainly moderate to severe pain – and this is potentially because of general lack of awareness of diaphragmatic endometriosis among the general population and medical professionals.

Findings of the international survey that explored the diagnosis and treatment of diaphragmatic endometriosis were presented at this year’s Royal College of Obstetricians and Gynecologists 2021 Virtual World Congress by medical student Rachel Piccus, MSc, based at the University of Birmingham (England). Robert Sutcliffe, MD, consultant in hepatobiliary and pancreatic surgery, at Queen Elizabeth Hospital Birmingham was senior author. Results were also published in the May 2021 issue of the European Journal of Obstetrics and Gynaecology and Reproductive Biology.

The study found that it took an average of five visits to a primary physician before referral to a gynecologist.

“Late diagnosis could also be due to the idea that diaphragmatic endometriosis symptoms often present before pelvic symptoms and therefore the site of pain is considered atypical for pelvic endometriosis,” Ms. Piccus said, adding that “clinicians are screening for cyclical pain, which is typical of endometriosis, but our study has shown that pain can in fact be more frequent – daily and weekly.”

These significant diagnostic delays, seen from the time of the initial primary care and gynecology consultation has the potential to significantly affect quality of life as seen in pelvic endometriosis, said Ms. Piccus. “These delays are partly due to a lack of awareness among gynecologists, but could also be due to pelvic laparoscopy being insufficient to examine the diaphragm behind the liver.”

Justin Clark, MD, consultant gynaecologist, Birmingham (England) Women’s and Children Hospital, moderated the session and agreed that the study highlights the need for greater awareness of this variant of endometriosis. “Whilst endometriosis affecting the diaphragm, subdiaphragm, and thorax is rare, the condition causes substantial morbidity.”

“Greater knowledge of thoracic endometriosis amongst clinicians in both primary and secondary care is needed to ensure accurate and timely diagnosis,” he added.

Diaphragmatic endometriosis is estimated to affect 1%-1.5% of all endometriosis patients and presents as cyclical pain in the chest, abdomen, and shoulder tip, as well as other respiratory symptoms such as catamenial pneumothorax and difficulty breathing.

“Cross-sectional imaging has shown low sensitivity so upper abdominal laparoscopy is the gold standard; however, this has implications for diagnostic delay because a strong clinical suspicion is required to refer for this invasive procedure,” explained Ms. Piccus referring to one of the reasons underpinning the need for the study.

When successfully diagnosed, treatment requires excision or ablation surgery and studies show symptomatic relief in 75%-100% of cases.

To gauge the extent of delayed diagnosis as well as treatment outcomes from a patient perspective, Ms. Piccus circulated an anonymous online survey among women with a previous history of surgery for diaphragmatic endometriosis.
 

Diaphragmatic endometriosis pain – daily and weekly as well as cyclical

A total of 137 participants responded to the survey, with a median age of 34 years (range, 19-53). Median age of diaphragmatic endometriosis onset was 27 years (range, 11-50), and importantly, diaphragmatic endometriosis symptoms started before pelvic symptoms in 90 respondents (66%).

The dominant symptom was pain. A total of 38% reported cyclical pain (related to endometrial shedding during menstruation), 15% weekly pain, and 47% daily pain, both of which were worse during the menstrual cycle. Furthermore, 14% reported other symptoms including catamenial pneumothorax, difficulty breathing, and hemoptysis.

“Whilst this cyclical pain is typical of endometriosis, we see that diagnostic delays may be due to misdiagnosis because clinicians are screening for this cyclical pain whilst our study has shown that pain can in fact be more frequent, being daily and weekly,” noted Ms. Piccus. Moderate to severe pain was reported in 67% of respondents and moderate in 31%, only 2% reported pain as mild.

Location of pain comprised moderate to severe pain in the upper abdomen (68%), chest (64%) and shoulder (54%). Pain was right-sided in 54%, left-sided in 11% and bilateral in 35%. Upper back and neck were also reported as sites of pain.

Indirectly providing a measure of the lack of awareness of diaphragmatic endometriosis on behalf of primary care, 122 participants reported initially visiting their primary care physician for help and 65 were given a diagnosis – in only 14 cases was that diaphragmatic endometriosis. There were a range of other gynecologic (e.g. ovarian cyst, two), respiratory (spontaneous pneumothorax, seven), gastrointestinal (gastritis/reflux, eight), musculoskeletal (six), and psychological (anxiety/stress, four) diagnoses.

A median of 5 primary care consultations (range, 1-100) were required before referral to a gynecologist, with 30% seeing a primary care physician over 10 times. A further 14 patients self-referred to gynecologist.

“These findings have implications for diagnostic delay, added Ms. Piccus. “While the majority of respondents were diagnosed less than a year from the first GP visit, the median delay was 2 years, with 31% diagnosed after 5 or more years. One took 23 years for an initial diagnosis.”

Most cases were diagnosed at the time of surgery – 93%, with 52% at pelvic laparoscopy, 35% upper abdominal laparoscopy, with 30% requiring two or more laparoscopies before they were diagnosed with diaphragmatic endometriosis. A total of 7% were diagnosed via cross-sectional imaging prior to surgery.
 

Treatment outcomes for diaphragmatic endometriosis

Reflecting the literature, surgery to remove the endometriosis lesions was mainly laparoscopic with 47% abdominal excisions, and 29% abdominal ablations; 6% received open abdominal procedures, and 18% received open thoracotomy or video-assisted thoracoscopic surgery.

The survey asked about postoperative symptoms 6 months after surgery and at the time of survey. Symptoms at 6 months post surgery had completely resolved in 18%, shown significant improvement in 48%, and no improvement in 20%. Worsening of symptoms was seen in 14%. Long-term pain was reported by 21% as severe, 27% as moderate, 35% as mild, and 17% had no symptoms.

Further findings included that 23% underwent additional procedures to treat their diaphragmatic endometriosis, and that there was no significant difference between excision and ablation, nor between age of onset of symptoms or length of diagnostic delay.

“Surgical treatment to remove these extra pelvic deposits of endometriosis will depend upon the type and distribution of thoracic endometriosis and a variety of surgical specialties may need to be involved including gynecologists, cardiothoracic, and upper gastrointestinal/liver surgeons,” Dr. Clark said.

He added that familiar hormonal medical treatments for more typical pelvic endometriosis should also be considered for primary and maintenance treatment. “These data suggest a high symptomatic recurrence rate after surgical treatment and so medical treatments should be considered to try and minimize the risks of endometriosis symptoms returning.”

Dr. Clark also pointed out that multidisciplinary clinical teams should be established in specialized centers to plan surgical and medical management to enhance clinical outcomes and collect data to better understand this enigmatic condition.

Ms. Piccus and Dr. Clark have no relevant conflicts of interest.

Although use of some herbal and dietary supplements show statistically greater weight loss compared with placebo, it is not sufficient to benefit health, according to the joint findings of two systematic reviews, which are the first to comprehensively include all available herbal and dietary supplements for weight loss for over 15 years.

“There is currently insufficient evidence to recommend any of the supplements we included in our reviews for weight loss,” stressed lead author Erica Bessell, a PhD candidate from the University of Sydney.

She added that some products with promising results warrant further investigation in well-conducted randomized controlled trials (RCTs) to determine their efficacy and safety.

But, overall, she would like to see a reduction in the number of products on the market without evidence to support their efficacy, “because, as we found, many of the products currently marketed for weight loss just do not work.

“Herbal and dietary supplements might seem like a quick-fix solution to weight problems, but people need to be aware of how little we actually know about them,” she said in an interview. “We would recommend that people trying to lose weight should save their money and seek out evidence-based care instead,” she emphasized.

The research was presented as two posters at this year’s online European Congress on Obesity (ECO). The meeting was presented by the European Association for the Study of Obesity.
 

Herbal and dietary supplement industry booming

Supplements for weight loss are growing in popularity, sustaining a rapidly expanding business sector globally. In the United States, the herbal and dietary supplements industry was estimated to be worth USD $41 billion in 2020, with 15% of Americans having tried a weight loss supplement in their efforts to shed pounds.

In light of this, Ms. Bessell said it is increasingly important to ensure supplements are efficacious and safe: “The popularity of these products underscores the urgency of conducting larger, more rigorous studies to have reasonable assurance of their safety and effectiveness for weight loss.”

Commenting on the study and the wider issues related to the surge in uptake of herbal and dietary supplements, Susan Arentz, PhD, said the evidence is similar to that for other complex interventions that people attempt for weight loss, including for example exercise, in that it is heterogeneous and low quality.

“One outstanding limitation for herbal medicine was the failure of trialists to validate the contents of interventions. Given the chemical variability of plants grown and harvested in different conditions, and the presence of pharmaceuticals and heavy metals found in some supplements ... future investigations of standardized herbal supplements and RCTs of higher methodological quality are needed,” remarked Dr. Arentz, a board member of the Australasian Integrative Medicine Association and researcher at Western Sydney University.

“Also, further RCTs are warranted due to the consumer preferences for natural treatments, especially in health settings with predominant use of traditional medicines and practices,” said Dr. Arentz.   
 

One review for herbal supplements, one for organic compounds

To accommodate the large number of trials investigating supplements for weight loss, the researchers conducted two systematic reviews, together representing 121 randomized placebo-controlled trials. One of the reviews investigated herbal supplements, and the other examined supplements with isolated organic compounds for example, specific fibers or lipids.  

Many of the included trials had been published in the last decade and had not been previously included in an up-to-date systematic review.

Ms. Bessell added that many studies often had a small sample size or were poorly designed, with insufficient information on the composition of supplements, and often featured little data on long-term effectiveness.

The two reviews primarily analyzed efficacy, not safety, because many of the studies did not report adverse effects.

The first review, published last year in Diabetes, Obesity and Metabolism, looked at 54 placebo-controlled randomized trials up to August 2018 on the effect of herbal supplements on weight loss . The study included 4,331 individuals aged 16 years or older who were overweight or obese. To be clinically meaningful, a weight loss of at least 2.5 kg was required over a period of, most often, 12 weeks or less.

Herbal supplements included in the analysis included green tea, Garcinia cambogia and mangosteen (tropical fruits), white kidney bean, ephedra (a stimulant that increases metabolism), African mango, yerba mate (herbal tea made from the leaves and twigs of the Ilex paraguariensis plant), veld grape (commonly used in Indian traditional medicine), licorice root, and East Indian Globe Thistle (used in Ayurvedic medicine).

The second review analyzed 67 randomized trials up to December 2019 that compared the effect of dietary supplements containing naturally occurring isolated organic compounds to placebo for weight loss in 5,194 individuals aged 16 years or older who were overweight or obese.

Meta-analyses were conducted for chitosan, glucomannan, conjugated linoleic acid, and fructans comparing the mean weight difference post intervention between participants receiving the dietary supplement and those on placebo.
 

No clinically significant results

Commenting on the overall results, Ms. Bessell said: “Though most supplements were safe for use in the short term, very few were found to produce clinically meaningful weight loss. Those that were found to result in clinically meaningful weight loss had only been investigated in one or two trials, so we need more research.”

The first review on herbal supplements found that only Phaseolus vulgaris (white kidney bean) resulted in significant weight loss compared with placebo, with an average weight difference of 1.61 kg (3.5 pounds). The result was not clinically meaningful, however.

For isolated organic compounds, significant weight differences compared with placebo were seen for chitosan, with a mean difference of 1.84 kg (4 pounds), glucomannan at 1.27 kg (2.8 pounds), and conjugated linoleic acid at 1.08 kg (2.4 pounds).

Again, none of these findings met the criteria for clinical significance (weight loss of 2.5 kg [5.5 pounds] or more).

In addition, some combination preparations containing African mango, veld grape, East Indian Globe Thistle, and mangosteen showed promising results with a mean weight difference of 1.85 kg (4 pounds), but were investigated in three or fewer trials, often with poor research methodology or reporting, and the findings should be interpreted with caution, the researchers noted.

Other dietary supplements, including modified cellulose – a plant fiber that expands in the stomach to induce a feeling of fullness – and blood orange juice extract, also showed encouraging results but were investigated in one trial and need more evidence before they can be recommended for weight loss, Ms. Bessell added.

She pointed out that some supplements are banned in some countries, such as ephedra (an extract from the plant Ephedra sinica). “This supplement is already banned in many countries because of the risk of serious adverse effects. The possibility of drug interactions may also be present with some other supplements, so health professionals and consumers should be aware of this.”

The isolated organic compounds supplements review was published in the International Journal of Obesity to coincide with the ECO 2021 conference.

Ms. Bessell has declared no relevant conflicts of interests. Dr. Arentz reviewed the systematic review of RCTs of herbal medicine supplements for weight loss published in Diabetes, Obesity and Metabolism.

Herbal supplements included in the analysis included green tea, Garcinia cambogia and mangosteen (tropical fruits), white kidney bean, ephedra (a stimulant that increases metabolism), African mango, yerba mate (herbal tea made from the leaves and twigs of the Ilex paraguariensis plant), veld grape (commonly used in Indian traditional medicine), licorice root, and East Indian Globe Thistle (used in Ayurvedic medicine).

The second review analyzed 67 randomized trials up to December 2019 that compared the effect of dietary supplements containing naturally occurring isolated organic compounds to placebo for weight loss in 5,194 individuals aged 16 years or older who were overweight or obese.

Meta-analyses were conducted for chitosan, glucomannan, conjugated linoleic acid, and fructans comparing the mean weight difference post intervention between participants receiving the dietary supplement and those on placebo.
 

No clinically significant results

Commenting on the overall results, Ms. Bessell said: “Though most supplements were safe for use in the short term, very few were found to produce clinically meaningful weight loss. Those that were found to result in clinically meaningful weight loss had only been investigated in one or two trials, so we need more research.”

The first review on herbal supplements found that only Phaseolus vulgaris (white kidney bean) resulted in significant weight loss compared with placebo, with an average weight difference of 1.61 kg (3.5 pounds). The result was not clinically meaningful, however.

For isolated organic compounds, significant weight differences compared with placebo were seen for chitosan, with a mean difference of 1.84 kg (4 pounds), glucomannan at 1.27 kg (2.8 pounds), and conjugated linoleic acid at 1.08 kg (2.4 pounds).

Again, none of these findings met the criteria for clinical significance (weight loss of 2.5 kg [5.5 pounds] or more).

In addition, some combination preparations containing African mango, veld grape, East Indian Globe Thistle, and mangosteen showed promising results with a mean weight difference of 1.85 kg (4 pounds), but were investigated in three or fewer trials, often with poor research methodology or reporting, and the findings should be interpreted with caution, the researchers noted.

Other dietary supplements, including modified cellulose – a plant fiber that expands in the stomach to induce a feeling of fullness – and blood orange juice extract, also showed encouraging results but were investigated in one trial and need more evidence before they can be recommended for weight loss, Ms. Bessell added.

She pointed out that some supplements are banned in some countries, such as ephedra (an extract from the plant Ephedra sinica). “This supplement is already banned in many countries because of the risk of serious adverse effects. The possibility of drug interactions may also be present with some other supplements, so health professionals and consumers should be aware of this.”

The isolated organic compounds supplements review was published in the International Journal of Obesity to coincide with the ECO 2021 conference.

Ms. Bessell has declared no relevant conflicts of interests. Dr. Arentz reviewed the systematic review of RCTs of herbal medicine supplements for weight loss published in Diabetes, Obesity and Metabolism.

Although use of some herbal and dietary supplements show statistically greater weight loss compared with placebo, it is not sufficient to benefit health, according to the joint findings of two systematic reviews, which are the first to comprehensively include all available herbal and dietary supplements for weight loss for over 15 years.

“There is currently insufficient evidence to recommend any of the supplements we included in our reviews for weight loss,” stressed lead author Erica Bessell, a PhD candidate from the University of Sydney.

She added that some products with promising results warrant further investigation in well-conducted randomized controlled trials (RCTs) to determine their efficacy and safety.

But, overall, she would like to see a reduction in the number of products on the market without evidence to support their efficacy, “because, as we found, many of the products currently marketed for weight loss just do not work.

“Herbal and dietary supplements might seem like a quick-fix solution to weight problems, but people need to be aware of how little we actually know about them,” she said in an interview. “We would recommend that people trying to lose weight should save their money and seek out evidence-based care instead,” she emphasized.

The research was presented as two posters at this year’s online European Congress on Obesity (ECO). The meeting was presented by the European Association for the Study of Obesity.
 

Herbal and dietary supplement industry booming

Supplements for weight loss are growing in popularity, sustaining a rapidly expanding business sector globally. In the United States, the herbal and dietary supplements industry was estimated to be worth USD $41 billion in 2020, with 15% of Americans having tried a weight loss supplement in their efforts to shed pounds.

In light of this, Ms. Bessell said it is increasingly important to ensure supplements are efficacious and safe: “The popularity of these products underscores the urgency of conducting larger, more rigorous studies to have reasonable assurance of their safety and effectiveness for weight loss.”

Commenting on the study and the wider issues related to the surge in uptake of herbal and dietary supplements, Susan Arentz, PhD, said the evidence is similar to that for other complex interventions that people attempt for weight loss, including for example exercise, in that it is heterogeneous and low quality.

“One outstanding limitation for herbal medicine was the failure of trialists to validate the contents of interventions. Given the chemical variability of plants grown and harvested in different conditions, and the presence of pharmaceuticals and heavy metals found in some supplements ... future investigations of standardized herbal supplements and RCTs of higher methodological quality are needed,” remarked Dr. Arentz, a board member of the Australasian Integrative Medicine Association and researcher at Western Sydney University.

“Also, further RCTs are warranted due to the consumer preferences for natural treatments, especially in health settings with predominant use of traditional medicines and practices,” said Dr. Arentz.   
 

One review for herbal supplements, one for organic compounds

To accommodate the large number of trials investigating supplements for weight loss, the researchers conducted two systematic reviews, together representing 121 randomized placebo-controlled trials. One of the reviews investigated herbal supplements, and the other examined supplements with isolated organic compounds for example, specific fibers or lipids.  

Many of the included trials had been published in the last decade and had not been previously included in an up-to-date systematic review.

Ms. Bessell added that many studies often had a small sample size or were poorly designed, with insufficient information on the composition of supplements, and often featured little data on long-term effectiveness.

The two reviews primarily analyzed efficacy, not safety, because many of the studies did not report adverse effects.

The first review, published last year in Diabetes, Obesity and Metabolism, looked at 54 placebo-controlled randomized trials up to August 2018 on the effect of herbal supplements on weight loss . The study included 4,331 individuals aged 16 years or older who were overweight or obese. To be clinically meaningful, a weight loss of at least 2.5 kg was required over a period of, most often, 12 weeks or less.

Herbal supplements included in the analysis included green tea, Garcinia cambogia and mangosteen (tropical fruits), white kidney bean, ephedra (a stimulant that increases metabolism), African mango, yerba mate (herbal tea made from the leaves and twigs of the Ilex paraguariensis plant), veld grape (commonly used in Indian traditional medicine), licorice root, and East Indian Globe Thistle (used in Ayurvedic medicine).

The second review analyzed 67 randomized trials up to December 2019 that compared the effect of dietary supplements containing naturally occurring isolated organic compounds to placebo for weight loss in 5,194 individuals aged 16 years or older who were overweight or obese.

Meta-analyses were conducted for chitosan, glucomannan, conjugated linoleic acid, and fructans comparing the mean weight difference post intervention between participants receiving the dietary supplement and those on placebo.

Vegetarians have more favorable levels of a number of biomarkers including cardiovascular-linked ones – total cholesterol, low-density lipoprotein cholesterol, and apolipoprotein A and B – than meat eaters, according to results of the largest study of its kind to date.

Results of the cross-sectional, observational study of 178,000 participants were presented as an electronic poster at this year’s online European Congress on Obesity by Jirapitcha Boonpor of the Institute of Cardiovascular & Medical Sciences, University of Glasgow (Scotland).

“We found that the health benefits of becoming a vegetarian were independent of adiposity and other sociodemographic and lifestyle-related confounding factors,” senior author Carlos Celis-Morales, PhD, also from the University of Glasgow, said in an interview.

Total cholesterol and LDL cholesterol concentrations for vegetarians were 21% and 16.4% lower than in meat eaters. But some biomarkers considered beneficial – including vitamin D concentrations – were lower in vegetarians, while some considered unhealthy – including triglycerides and cystatin-C levels – were higher.  

Vegetarian diets have recently become much more popular, but there is insufficient information about the health benefits. Prior reports of associations between biomarkers and a vegetarian diet were unclear, including evidence of any metabolic benefits, noted Dr. Celis-Morales.

Importantly, participants in the study had followed a vegetarian or meat-eater diet for at least 5 years before their biomarkers in blood and urine were assessed.

“If you modify your diet, then, 2 weeks later, you can see changes in some metabolic markers, but changes in markers of cardiovascular disease will take 5-10 years,” he explained.
 

No single biomarker can assess health

Asked to comment on the findings, John C. Mathers, PhD, noted that they clearly confirm the importance of not reading any biomarker result in isolation.

Health is complex and individual markers tell you just part of the story,” said Dr. Mathers of the Human Nutrition Research Centre, Newcastle (England) University.

He says a vegetarian diet can be nourishing but cautioned that “just because someone excludes meat from their diet does not mean necessarily that they will be eating a healthy diet.”

“Some of the biomarker differences seen in this work – such as the lower concentrations of total cholesterol and LDL cholesterol, GGT [gamma-glutamyl transferase], and ALT [alanine transaminase] – are indicators that the vegetarians were healthier than the meat eaters. However, other differences were less encouraging, including the lower concentrations of vitamin D and higher concentrations of triglycerides and cystatin-C.”

Also reflecting on the results, Jose Lara Gallegos, PhD, senior lecturer in human nutrition at Northumbria University, Newcastle upon Tyne, England, said they support previous evidence from large studies such as the European Prospective Investigation into Cancer and Nutrition (EPIC), which showed that a vegetarian diet is associated with a lower risk of heart disease.

“A vegetarian diet might also be associated with lower risk for liver diseases such as nonalcoholic fatty liver disease,” Dr. Gallegos said, but added that some levels of biomarkers considered to be “healthy” were lower in the vegetarians, and it is important to remember that strictly restricted diets might be associated with potential risks of nutritional inadequacies.

“Other, less restrictive dietary patterns, such as a Mediterranean diet, are also associated with ... health benefits,” he observed.
 

Large data sample from the UK Biobank study

“Specifically, we wanted to know if vegetarians were healthier because they are generally leaner and lead healthier lives, or whether their diet specifically was responsible for their improved metabolic and cardiovascular health,” Dr. Celis-Morales explained.

Data were included from 177,723 healthy participants from the UK Biobank study who were aged 37-73 years and had reported no major dietary changes over the last 5 years. In total, 4,111 participants were self-reported vegetarians who followed a diet without red meat, poultry, or fish, and 166,516 participants were meat eaters.

Nineteen biomarkers related to diabetes, hypertension, cardiovascular diseases, cancer, and liver and renal function were included, and the associations between vegetarian diet and biomarkers, compared with meat eaters, were examined.

To minimize confounding, the findings were adjusted for age, sex, deprivation, education, ethnicity, smoking, total sedentary time, type of physical activity, alcohol intake, body mass index, and waist circumference.

Compared with meat eaters, vegetarians had significantly lower concentrations of 14 biomarkers, including total cholesterol (21% lower); LDL (16% lower); lipoprotein A (1% lower), lipoprotein B (4% lower), and liver function markers (GGT: 354% lower, and ALT: 153% lower), IGF-1 (134% lower), urate (122% lower), total protein (29% lower), creatinine (607% lower), and C-reactive protein (10% lower).

However, the researchers found that, compared with meat eaters, vegetarians had significantly higher concentrations of some unhealthy biomarkers, including triglycerides (15% higher) and cystatin-C (4% higher), and lower levels of some beneficial biomarkers including high-density lipoprotein (HDL) cholesterol (5% lower), vitamin D (635% lower), and calcium (0.7% lower).

No associations were found for hemoglobin A1c, systolic blood pressure, and aminotransferase.

“Some biomarkers, for example urate, were very low in vegetarians, and this served to verify our results because we expected meat eaters to have higher levels of urate,” remarked Dr. Celis-Morales.
 

Diet commitment and cardiovascular outcomes

Many people, whether vegetarians or meat-eaters, follow short-term diets, for example, the Atkins or the 5:2 diet, and often lack continuity switching from one diet to the next, or back to regular eating.  

“They are healthy, but they do not commit for long enough to make a difference to metabolic markers or potentially long-term health. In contrast, vegetarians are usually fully committed but the reasons behind this commitment might be a concern for the environment or animal welfare, for example,” Dr. Celis-Morales pointed out.

However, he added that many vegetarians replace the meat in their diet with unhealthy alternatives. “They often eat too much pasta or potatoes, or other high-energy food with low nutritional value.”

Having identified metabolic markers specific to long-term vegetarian diets, Dr. Celis-Morales wanted to know what happens to vegetarians’ long-term cardiovascular health. He analyzed and published these outcomes in a separate study published in December 2020.

“Over 9 years of follow-up, we have found that vegetarians have a lower risk in terms of myocardial infarction in the long-term, as well as other cardiovascular disease,” he reported.

Asked whether there was an optimum age or time in life to become a vegetarian to improve health, Dr. Celis-Morales explained that the healthier you are, the less likely you will reap the health benefits of dietary changes – for example to being a vegetarian.

“It is more likely that those people who have unhealthy lifestyle risk factors, such as smoking, and high consumption of high-energy foods or processed meat are more likely to see positive health effects,” he said.  

Lifestyle changes to improve cardiovascular outcomes are usually more likely to be required at 40 or 50 years old than at younger ages. He also noted that metabolic markers tend to show clear improvement at around 3 months after adopting a particular diet but improvements in disease outcomes take a lot longer to become evident.

Dr. Celis-Morales and his team are currently conducting a further analysis to understand if the vegetarian diet is also associated with a lower risk of cancer, depression, and dementia, compared with meat-eaters.

Dr. Celis-Morales, Dr. Mathers, and Dr. Gallegos have reported no relevant financial relationships.
