Does Bariatric Surgery Also Improve Thyroid Function?
TOPLINE:
Metabolic/bariatric surgery (MBS) reduces thyroid-stimulating hormone (TSH), free triiodothyronine (fT3) levels, and thyroid hormone resistance indices in patients with obesity, changes strongly correlated with improvement in body composition.
METHODOLOGY:
- Recent studies have linked obesity with increased levels of TSH and thyroid hormones; however, the role that body fat distribution plays in this association remains unclear.
- This retrospective observational study evaluated the effects of MBS on thyroid hormone levels and thyroid hormone resistance in euthyroid individuals with obesity, focusing on the correlation with changes in body composition.
- Researchers included 470 patients with obesity (mean age, 33.4 years; mean body mass index [BMI], 37.9; 63.2% women) and 118 control individuals without obesity (mean BMI, 21.8), who had had normal levels of TSH, fT3, and free thyroxine.
- Among the patients with obesity, 125 underwent MBS and had thyroid tests both before and ≥ 3 months after surgery.
- Data on body composition and thyroid function were collected, and correlations between baseline and changes in thyroid function and body composition were assessed.
TAKEAWAY:
- Individuals with obesity had higher baseline TSH and fT3 levels (P < .001) and thyroid feedback quantile-based index (TFQI; P = .047) than those without obesity, with the values decreasing after MBS (all P < .001).
- Among individuals with obesity, preoperative TSH was positively correlated with the visceral fat area (VFA; P = .019) and body fat percentage (P = .013) and negatively correlated with skeletal muscle mass percentage (P = .024)
- The decrease in TSH post-surgery positively correlated with decreased VFA (P = .021) and decreased body fat percentage (P = .031).
- Decrease in VFA and body fat percentage after MBS was also associated with improved central thyroid hormone resistance indicated by TFQI.
IN PRACTICE:
“The relationship between obesity and [thyroid hormone] is bidirectional, indicating that addressing underlying thyroid disturbance could potentially benefit weight loss and metabolism,” the authors wrote.
SOURCE:
This study was led by Yu Yan, MD, Department of Pancreatic and Metabolic Surgery, Medical School of Southeast University, Nanjing Drum Tower Hospital, Nanjing, China, and published online in The Journal of Clinical Endocrinology & Metabolism.
LIMITATIONS:
The retrospective nature of this study limited the ability to definitively attribute changes in thyroid function and thyroid hormone resistance to changes in body composition. The relatively short duration of the study and the exclusion of individuals taking medications affecting thyroid function may also limit the generalizability of the findings.
DISCLOSURES:
This study was supported by the Fundings for Clinical Trials from the Affiliated Drum Tower Hospital, Nanjing University Medical School, Nanjing, China. The authors declared no potential conflicts of interest.

Environmental, Metabolic Factors Driving Global Rise in Stroke
Air pollution, high temperatures, and metabolic risk factors are driving global increases in stroke, contributing to 12 million cases and more than 7 million deaths from stroke each year, new data from the Global Burden of Disease (GBD) study showed.
Between 1990 and 2021, the number of people who experienced a stroke increased to 11.9 million (up by 70% since 1990), while the number of stroke survivors rose to 93.8 million (up by 86%), and stroke-related deaths rose to 7.3 million (up by 44%), making stroke the third leading cause of death worldwide after ischemic heart disease and COVID-19, investigators found.
Stroke is highly preventable, the investigators noted, with 84% of the stroke burden in 2021 attributable to 23 modifiable risk factors, including air pollution, excess body weight, high blood pressure, smoking, and physical inactivity.
This means there are “tremendous opportunities to alter the trajectory of stroke risk for the next generation,” Catherine O. Johnson, MPH, PhD, co-author and lead research scientist at the Institute for Health Metrics and Evaluation (IHME), University of Washington, Seattle, said in a news release.
The study was published online in The Lancet Neurology.
Top Risk Factor for Subarachnoid Hemorrhage
Since 1990, the contribution of high temperatures to poor health and early death due to stroke has risen 72%, a trend likely to increase in the future — underscoring the impact of environmental factors on the growing stroke burden, the authors said.
“Given that ambient air pollution is reciprocally linked with ambient temperature and climate change, the importance of urgent climate actions and measures to reduce air pollution cannot be overestimated,” Dr. Johnson said.
Mitchell S.V. Elkind, MD, MS, chief clinical science officer for the American Heart Association, who wasn’t involved in the study, told this news organization that environmental factors such as air pollution, particulate matter from wildfires and other sources, and excessive heat are now recognized as major contributors to the risk for stroke. “This should not be surprising as we have long recognized the risks of stroke associated with toxins in cigarette smoke, which likely share mechanisms for vascular damage with pollutants,” Dr. Elkind said.
The data also reveal for the first time that ambient particulate matter air pollution is a top risk factor for subarachnoid hemorrhage, contributing to 14% of the death and disability caused by this serious stroke subtype, on a par with smoking.
Dr. Elkind noted that smoking is “a major risk factor for subarachnoid hemorrhage. It makes sense that particulate air pollution would therefore similarly be a risk factor for subarachnoid hemorrhage, which similarly damages blood vessels. Prior studies were likely too small or did not assess the role of air pollution in subarachnoid hemorrhage.”
The analysis also showed substantial increases between 1990 and 2021 in the global stroke burden linked to high body mass index (up by 88%), high blood sugar (up 32%), a diet high in sugar-sweetened drinks (up 23%), low physical activity (up 11%), high systolic blood pressure (up 7%), and a diet low in omega-6 polyunsaturated fatty acids (up 5%).
“And with increasing exposure to risk factors such as high blood sugar and diet high in sugar-sweetened drinks, there is a critical need for interventions focused on obesity and metabolic syndromes,” Dr. Johnson said.
“Identifying sustainable ways to work with communities to take action to prevent and control modifiable risk factors for stroke is essential to address this growing crisis,” she added.
Prevention Strategies Fall Short
The data also showed that stroke-related disability-adjusted life-years rose from around 121.4 million years of healthy life lost in 1990 to 160.5 million years in 2021, making stroke the fourth leading cause of health loss worldwide after COVID-19, ischemic heart disease, and neonatal disorders.
“The global growth of the number of people who develop stroke and died from or remain disabled by stroke is growing fast, strongly suggesting that currently used stroke prevention strategies are not sufficiently effective,” lead author Valery L. Feigin, MD, PhD, from Auckland University of Technology, Auckland, New Zealand, and affiliate professor at IHME, said in the release.
“New, proven effective population-wide and motivational individual prevention strategies that could be applied to all people at risk of having a stroke, regardless of the level of risk, as recommended in the recent Lancet Neurology Commission on Stroke should be implemented across the globe urgently,” said Dr. Feigin.
Dr. Elkind said the AHA supports research on the effects of air quality on risk for vascular injury and stroke and has “long advocated for policies to mitigate the adverse health impacts of air pollutants, including reduction of vehicle emissions and renewable portfolio standards, taking into account racial, ethnic, and economic disparities.”
“AHA, and the healthcare sector more broadly, must take a leadership role in recommending policies to improve environmental air quality and in working with the private sector and industry to improve air quality,” Dr. Elkind said.
In an accompanying commentary, Ming Liu, MD, and Simiao Wu, MD, PhD, West China Hospital, Sichuan University, Chengdu, China, wrote that “pragmatic solutions to the enormous and increasing stroke burden include surveillance, prevention, acute care, and rehabilitation.”
“Surveillance strategies include establishing a national-level framework for regular monitoring of stroke burden, risk factors, and healthcare services via community-based surveys and health records,” they noted.
“Artificial intelligence and mobile technologies might not only facilitate the dissemination of evidence-based health services but also increase the number of data sources and encourage participation of multidisciplinary collaborators, potentially improving the validity and accuracy of future GBD estimates,” they added.

Semaglutide Bests Liraglutide in Long-Term Weight Loss
Patients with obesity or type 2 diabetes (T2D) who stuck with their medication for a year lost more weight with semaglutide than with liraglutide, a new study reported.
Researchers at the Cleveland Clinic reviewed records for 3389 adult patients with obesity who were prescribed one of the glucagon-like peptide 1 (GLP-1) medications for either T2D or obesity between 2015 and 2022. They found that patients who took either semaglutide or liraglutide for obesity were more likely to lose weight than those prescribed the medications for T2D and that semaglutide was associated with greater weight loss.
The study, published in JAMA Network Open, identified “key characteristics that could inform the probability of achieving sustained weight loss of a magnitude large enough to provide clinically significant health benefits,” said lead author Hamlet Gasoyan, PhD, a staff investigator at the Center for Value-Based Care Research in the Department of Internal Medicine of Primary Care Institute, Cleveland Clinic, Cleveland.
Only about 40% of patients continued to take the medications at 1 year. Those who did not continue did not achieve the same level of weight loss, Dr. Gasoyan told this news organization. He and his colleagues will study the factors that lead patients to stop taking the medications in a future paper.
The results from the current paper give patients and clinicians reasonable expectations on the trajectory of weight loss when the drugs are prescribed for diabetes vs obesity, said Dr. Gasoyan, assistant professor of medicine at Cleveland Clinic Lerner College of Medicine of Case Western Reserve University, Cleveland.
Semaglutide Superior
Because of the study’s timeframe, the majority of GLP-1s were prescribed for T2D. Liraglutide was approved (as Saxenda) for obesity in December 2020 and semaglutide (as Wegovy) for obesity in June 2021.
The authors were able to capture fills under the brand names and doses approved by the US Food and Drug Administration (FDA) for obesity (Wegovy, 1.7 or 2.4 mg; Saxenda, 3.0 mg), as well as those approved for T2D (Ozempic, 0.5, 1.0, or 2.0 mg; Victoza, 1.2 or 1.8 mg).
The researchers reported that among the 3389 patients, 1341 (39.6%) were prescribed semaglutide and 1444 (42.6%) were prescribed liraglutide for T2D. For obesity, 227 (6.7%) were prescribed liraglutide, and 377 (11.1%) were prescribed semaglutide.
Overall, those with diabetes had a −3.2% mean weight change compared with those with obesity who had a −5.9% mean weight change.
Semaglutide consistently outperformed liraglutide, particularly in obesity.
Overall, at 1 year, the mean percentage weight change among those with obesity was −5.1% with semaglutide compared with −2.2% with liraglutide (P < .001).
At 1 year, among those with obesity who were persistent in semaglutide use (defined as 90-275 medication days) had a mean body weight of −12.9% vs −5.6% in those taking liraglutide.
Overall, about 40% of patients were persistent at 1 year. But the figure was higher for semaglutide (45.8%) and lower for liraglutide (35.6%).
Liraglutide requires daily injections compared with semaglutide that requires weekly injections. The authors did not study the reasons for medication adherence or discontinuation.
Key factors for achieving a greater than 10% weight loss — considered clinically meaningful — included taking semaglutide, receiving a GLP-1 for obesity, persistent medication use, high dosage, and being female.
Real-World Data Welcomed
Michael Weintraub, MD, an obesity medicine specialist and clinical assistant professor at NYU Langone Health, New York City, said that having real-world data on GLP-1 effectiveness has been much needed.
The researchers “did a really good job at stratifying these patients,” he told this news organization, saying that the study “adds to the literature in terms of what we might expect and what things we should look out for when we want to obtain the maximum degree of weight loss and attain overall better metabolic health for our patients.”
One strength: The researchers were able to capture when someone actually filled a prescription, he said. Clinicians don’t always know whether a prescription for a GLP-1 has been filled because patients might go without the drug because of insurance hurdles or supply issues, he said.
Dr. Weintraub was not surprised that the study showed that both GLP-1s produced more weight loss in those with obesity than in those with T2D, as that has become a common finding. No one has been able to explain why there is such a difference, said Dr. Weintraub. “As a field, we actually don’t know the reason behind that yet,” he said.
Given the small number of patients prescribed semaglutide for obesity, that “limits the generalizability,” he said.
Even so, semaglutide is increasingly proving superior, Dr. Weintraub said. “I would reach towards semaglutide every time either for individuals with type 2 diabetes or individuals with obesity,” he said. “The major limitation, though, is insurance coverage rather than, unfortunately, my clinical decision-making.”
He also still sees a role for liraglutide. It will go off patent soon and that could “lead to a lower price point and hopefully greater access for patients,” he said.
Dr. Gasoyan and Dr. Weintraub reported no relevant financial relationships. One coauthor reported receiving advisory board fees from Novo Nordisk and research funding from Eli Lilly during the conduct of the study.

Overall, about 40% of patients were persistent at 1 year. But the figure was higher for semaglutide (45.8%) and lower for liraglutide (35.6%).
Liraglutide requires daily injections compared with semaglutide that requires weekly injections. The authors did not study the reasons for medication adherence or discontinuation.
Key factors for achieving a greater than 10% weight loss — considered clinically meaningful — included taking semaglutide, receiving a GLP-1 for obesity, persistent medication use, high dosage, and being female.
Real-World Data Welcomed
Michael Weintraub, MD, an obesity medicine specialist and clinical assistant professor at NYU Langone Health, New York City, said that having real-world data on GLP-1 effectiveness has been much needed.
The researchers “did a really good job at stratifying these patients,” he told this news organization, saying that the study “adds to the literature in terms of what we might expect and what things we should look out for when we want to obtain the maximum degree of weight loss and attain overall better metabolic health for our patients.”
One strength: The researchers were able to capture when someone actually filled a prescription, he said. Clinicians don’t always know whether a prescription for a GLP-1 has been filled because patients might go without the drug because of insurance hurdles or supply issues, he said.
Dr. Weintraub was not surprised that the study showed that both GLP-1s produced more weight loss in those with obesity than in those with T2D, as that has become a common finding. No one has been able to explain why there is such a difference, said Dr. Weintraub. “As a field, we actually don’t know the reason behind that yet,” he said.
Given the small number of patients prescribed semaglutide for obesity, that “limits the generalizability,” he said.
Even so, semaglutide is increasingly proving superior, Dr. Weintraub said. “I would reach towards semaglutide every time either for individuals with type 2 diabetes or individuals with obesity,” he said. “The major limitation, though, is insurance coverage rather than, unfortunately, my clinical decision-making.”
He also still sees a role for liraglutide. It will go off patent soon and that could “lead to a lower price point and hopefully greater access for patients,” he said.
Dr. Gasoyan and Dr. Weintraub reported no relevant financial relationships. One coauthor reported receiving advisory board fees from Novo Nordisk and research funding from Eli Lilly during the conduct of the study.

Patients with obesity or type 2 diabetes (T2D) who stuck with their medication for a year lost more weight with semaglutide than with liraglutide, a new study reported.
Researchers at the Cleveland Clinic reviewed records for 3389 adult patients with obesity who were prescribed one of the glucagon-like peptide 1 (GLP-1) medications for either T2D or obesity between 2015 and 2022. They found that patients who took either semaglutide or liraglutide for obesity were more likely to lose weight than those prescribed the medications for T2D and that semaglutide was associated with greater weight loss.
The study, published in JAMA Network Open, identified “key characteristics that could inform the probability of achieving sustained weight loss of a magnitude large enough to provide clinically significant health benefits,” said lead author Hamlet Gasoyan, PhD, a staff investigator at the Center for Value-Based Care Research in the Department of Internal Medicine of Primary Care Institute, Cleveland Clinic, Cleveland.
Only about 40% of patients continued to take the medications at 1 year. Those who did not continue did not achieve the same level of weight loss, Dr. Gasoyan told this news organization. He and his colleagues will study the factors that lead patients to stop taking the medications in a future paper.
The results from the current paper give patients and clinicians reasonable expectations on the trajectory of weight loss when the drugs are prescribed for diabetes vs obesity, said Dr. Gasoyan, assistant professor of medicine at Cleveland Clinic Lerner College of Medicine of Case Western Reserve University, Cleveland.
Semaglutide Superior
Because of the study’s timeframe, the majority of GLP-1s were prescribed for T2D. Liraglutide was approved (as Saxenda) for obesity in December 2020 and semaglutide (as Wegovy) for obesity in June 2021.
The authors were able to capture fills under the brand names and doses approved by the US Food and Drug Administration (FDA) for obesity (Wegovy, 1.7 or 2.4 mg; Saxenda, 3.0 mg), as well as those approved for T2D (Ozempic, 0.5, 1.0, or 2.0 mg; Victoza, 1.2 or 1.8 mg).
The researchers reported that among the 3389 patients, 1341 (39.6%) were prescribed semaglutide and 1444 (42.6%) were prescribed liraglutide for T2D. For obesity, 227 (6.7%) were prescribed liraglutide, and 377 (11.1%) were prescribed semaglutide.
Overall, those with diabetes had a −3.2% mean weight change compared with those with obesity who had a −5.9% mean weight change.
Semaglutide consistently outperformed liraglutide, particularly in obesity.
Overall, at 1 year, the mean percentage weight change among those with obesity was −5.1% with semaglutide compared with −2.2% with liraglutide (P < .001).
At 1 year, among those with obesity who were persistent in semaglutide use (defined as 90-275 medication days) had a mean body weight of −12.9% vs −5.6% in those taking liraglutide.
Overall, about 40% of patients were persistent at 1 year. But the figure was higher for semaglutide (45.8%) and lower for liraglutide (35.6%).

Controlling Six Risk Factors Can Combat CKD in Obesity
TOPLINE:
Optimal management of blood pressure, A1c levels, low-density lipoprotein cholesterol (LDL-C), albuminuria, smoking, and physical activity may reduce the excess risk for chronic kidney disease (CKD) typically linked to obesity. The protective effect is more pronounced in men, in those with lower healthy food scores, and in users of diabetes medication.
METHODOLOGY:
- Obesity is a significant risk factor for CKD, but it is unknown if managing multiple other obesity-related CKD risk factors can mitigate the excess CKD risk.
- Researchers assessed CKD risk factor control in 97,538 participants with obesity from the UK Biobank and compared them with an equal number of age- and sex-matched control participants with normal body weight and no CKD at baseline.
- Participants with obesity were assessed for six modifiable risk factors: Blood pressure, A1c levels, LDL-C, albuminuria, smoking, and physical activity.
- Overall, 2487, 12,720, 32,388, 36,988, and 15,381 participants with obesity had at most two, three, four, five, and six risk factors under combined control, respectively, with the two or fewer group serving as the reference.
- The primary outcome was incident CKD and the degree of combined risk factor control in persons. The CKD risk and risk factor control in participants with obesity were also compared with CKD incidence in matched normal weight participants.
TAKEAWAY:
- During a median follow-up period of 10.8 years, 3954 cases of incident CKD were reported in participants with obesity and 1498 cases in matched persons of normal body mass index (BMI).
- In a stepwise pattern, optimal control of each additional risk factor was associated with 11% (adjusted hazard ratio [aHR], 0.89; 95% CI, 0.86-0.91) reduction in the incidence of CKD events, down to a 49% reduction in CKD incidence (aHR, 0.51; 95% CI, 0.43-0.61) for combined control of all six risk factors in participants with obesity.
- The protective effect of combined control of risk factors was more pronounced in men vs women, in those with lower vs higher healthy diet scores, and in users vs nonusers of diabetes medication.
- A similar stepwise pattern emerged between the number of risk factors controlled and CKD risk in participants with obesity compared with matched individuals of normal BMI, with the excess CKD risk eliminated in participants with obesity with six risk factors under control.
IN PRACTICE:
“Comprehensive control of risk factors might effectively neutralize the excessive CKD risk associated with obesity, emphasizing the potential of a joint management approach in the prevention of CKD in this population,” the authors wrote.
SOURCE:
The study was led by Rui Tang, MS, Department of Epidemiology, School of Public Health and Tropical Medicine, Tulane University, New Orleans, Louisiana. It was published online in Diabetes, Obesity and Metabolism.
LIMITATIONS:
The evaluated risk factors for CKD were arbitrarily selected, which may not represent the ideal group. The study did not consider the time-varying effect of joint risk factor control owing to the lack of some variables such as A1c. The generalizability of the findings was limited because over 90% of the UK Biobank cohort is composed of White people and individuals with healthier behaviors compared with the overall UK population.
DISCLOSURES:
The study was supported by grants from the US National Heart, Lung, and Blood Institute and the National Institute of Diabetes and Digestive and Kidney Diseases. The authors declared no conflicts of interest.

Hidden in Plain Sight: The Growing Epidemic of Ultraprocessed Food Addiction
Yet, even as this evidence mounted, these food items have become increasingly prominent in diets globally.
Now, recent studies are unlocking why cutting back on ultraprocessed foods can be so challenging. In their ability to fuel intense cravings, loss of control, and even withdrawal symptoms, ultraprocessed foods appear as capable of triggering addiction as traditional culprits like tobacco and alcohol.
This has driven efforts to better understand the addictive nature of these foods and identify strategies for combating it.
The Key Role of the Food Industry
Some foods are more likely to trigger addictions than others. For instance, in our studies, participants frequently mention chocolate, pizza, French fries, potato chips, and soda as some of the most addictive foods. What these foods all share is an ability to deliver high doses of refined carbohydrates, fat, or salt at levels exceeding those found in natural foods (eg, fruits, vegetables, beans).
Furthermore, ultraprocessed foods are industrially mass-produced in a process that relies on the heavy use of flavor enhancers and additives, as well as preservatives and packaging that make them shelf-stable. This has flooded our food supply with cheap, accessible, hyperrewarding foods that our brains are not well equipped to resist.
To add to these already substantial effects, the food industry often employs strategies reminiscent of Big Tobacco. They engineer foods to hit our “bliss points,” maximizing craving and fostering brand loyalty from a young age. This product engineering, coupled with aggressive marketing, makes these foods both attractive and seemingly ubiquitous.
How Many People Are Affected?
Addiction to ultraprocessed food is more common than you might think. According to the Yale Food Addiction Scale — a tool that uses the same criteria for diagnosing substance use disorders to assess ultraprocessed food addiction (UPFA) — about 14% of adults and 12% of children show clinically significant signs of addiction to such foods. This is quite similar to addiction rates among adults for legal substances like alcohol and tobacco.
Research has shown that behaviors and brain mechanisms contributing to addictive disorders, such as cravings and impulsivity, also apply to UPFA.
Many more people outside of those who meet the criteria for UPFA are influenced by their addictive properties. Picture a teenager craving a sugary drink after school, a child needing the morning cereal fix, or adults reaching for candy and fast food; these scenarios illustrate how addictive ultraprocessed foods permeate our daily lives.
From a public health standpoint, this comes at a significant cost. Even experiencing one or two symptoms of UPFA, such as intense cravings or a feeling of loss of control over intake, can lead to consuming too many calories, sugar, fat, and sodium in a way that puts health at risk.
Clinical Implications
Numerous studies have found that individuals who exhibit UPFA have more severe mental and physical health challenges. For example, UPFA is associated with higher rates of diet-related diseases (like type 2 diabetes), greater overall mental health issues, and generally poorer outcomes in weight loss treatments.
Despite the growing understanding of UPFA’s relevance in clinical settings, research is still limited on how to best treat, manage, or prevent it. Most of the existing work has focused on investigating whether UPFA is indeed a real condition, with efforts to create clinical guidelines only just beginning.
Of note, UPFA isn’t officially recognized as a diagnosis — yet. If it were, it could spark much more research into how to handle it clinically.
There is some debate about whether we really need this new diagnosis, given that eating disorders are already recognized. However, the statistics tell a different story: Around 14% of people might have UPFA compared with about 1% for binge-type eating disorders. This suggests that many individuals with problematic eating habits are currently flying under the radar with our existing diagnostic categories.
What’s even more concerning is that these individuals often suffer significant problems and exhibit distinct brain differences, even if they do not neatly fit into an existing eating disorder diagnosis. Officially recognizing UPFA could open up new avenues for support and lead to better treatments aimed at reducing compulsive eating patterns.
Treatment Options
Treatment options for UPFA are still being explored. Initial evidence suggests that medications used for treating substance addiction, such as naltrexone and bupropion, might help with highly processed food addiction as well. Newer drugs, like glucagon-like peptide-1 receptor agonists, which appear to curb food cravings and manage addictive behaviors, also look promising.
Psychosocial approaches can also be used to address UPFA. Strategies include:
- Helping individuals become more aware of their triggers for addictive patterns of intake. This often involves identifying certain types of food (eg, potato chips, candy), specific places or times of day (eg, sitting on the couch at night while watching TV), and particular emotional states (eg, anger, loneliness, boredom, sadness). Increasing awareness of personal triggers can help people minimize their exposure to these and develop coping strategies when they do arise.
- Many people use ultraprocessed foods to cope with challenging emotions. Helping individuals develop healthier strategies to regulate their emotions can be key. This may include seeking out social support, journaling, going for a walk, or practicing mindfulness.
- UPFA can be associated with erratic and inconsistent eating patterns. Stabilizing eating habits by consuming regular meals composed of more minimally processed foods (eg, vegetables, fruits, high-quality protein, beans) can help heal the body and reduce vulnerability to ultraprocessed food triggers.
- Many people with UPFA have other existing mental health conditions, including mood disorders, anxiety, substance use disorders, or trauma-related disorders. Addressing these co-occurring mental health conditions can help reduce reliance on ultraprocessed foods.
Public-policy interventions may also help safeguard vulnerable populations from developing UPFA. For instance, support exists for policies to protect children from cigarette marketing and to put clear addiction warning labels on cigarette packages. A similar approach could be applied to reduce the harms associated with ultraprocessed foods, particularly for children.
Combating this growing problem requires treating ultraprocessed foods like other addictive substances. By identifying the threat posed by these common food items, we can not only help patients with UPFA, but also potentially stave off the development of several diet-related conditions.

This suggests that many individuals with problematic eating habits are currently flying under the radar with our existing diagnostic categories.
What’s even more concerning is that these individuals often suffer significant problems and exhibit distinct brain differences, even if they do not neatly fit into an existing eating disorder diagnosis. Officially recognizing UPFA could open up new avenues for support and lead to better treatments aimed at reducing compulsive eating patterns.
Treatment Options
Treatment options for UPFA are still being explored. Initial evidence suggests that medications used for treating substance addiction, such as naltrexone and bupropion, might help with highly processed food addiction as well. Newer drugs, like glucagon-like peptide-1 receptor agonists, which appear to curb food cravings and manage addictive behaviors, also look promising.
Psychosocial approaches can also be used to address UPFA. Strategies include:
- Helping individuals become more aware of their triggers for addictive patterns of intake. This often involves identifying certain types of food (eg, potato chips, candy), specific places or times of day (eg, sitting on the couch at night while watching TV), and particular emotional states (eg, anger, loneliness, boredom, sadness). Increasing awareness of personal triggers can help people minimize their exposure to these and develop coping strategies when they do arise.
- Many people use ultraprocessed foods to cope with challenging emotions. Helping individuals develop healthier strategies to regulate their emotions can be key. This may include seeking out social support, journaling, going for a walk, or practicing mindfulness.
- UPFA can be associated with erratic and inconsistent eating patterns. Stabilizing eating habits by consuming regular meals composed of more minimally processed foods (eg, vegetables, fruits, high-quality protein, beans) can help heal the body and reduce vulnerability to ultraprocessed food triggers.
- Many people with UPFA have other existing mental health conditions, including mood disorders, anxiety, substance use disorders, or trauma-related disorders. Addressing these co-occurring mental health conditions can help reduce reliance on ultraprocessed foods.
Public-policy interventions may also help safeguard vulnerable populations from developing UPFA. For instance, support exists for policies to protect children from cigarette marketing and to put clear addiction warning labels on cigarette packages. A similar approach could be applied to reduce the harms associated with ultraprocessed foods, particularly for children.
Combating this growing problem requires treating ultraprocessed foods like other addictive substances. By identifying the threat posed by these common food items, we can not only help patients with UPFA, but also potentially stave off the development of several diet-related conditions.

Bariatric Surgery and Weight Loss Make Brain Say Meh to Sweets
TOPLINE:
METHODOLOGY:
- Previous studies have suggested that individuals undergoing bariatric surgery show reduced preference for sweet-tasting food post-surgery, but the mechanisms behind these changes remain unclear.
- This observational cohort study aimed to examine the neural processing of sweet taste in the reward regions of the brain before and after bariatric surgery in 24 women with obesity (mean body mass index [BMI], 47) who underwent bariatric surgery and 21 control participants with normal to overweight (mean BMI, 23.5).
- Participants (mean age about 43 years; 75%-81% White) underwent sucrose taste testing and functional MRI (fMRI) to compare the responses of the brain with sucrose solutions of 0.10 M and 0.40 M (akin to sugar-sweetened beverages, such as Coca-Cola at ~0.32 M) and Mountain Dew at ~0.35 M) versus water.
- In the bariatric surgery group, participants underwent fMRI 1-117 days before surgery, and 21 participants who lost about 20% of their weight after the surgery underwent a follow-up fMRI roughly 3-4 months later.
- The researchers analyzed the brain’s reward response using a composite activation of several reward system regions (the ventral tegmental area, ventral striatum, and orbitofrontal cortex) and of sensory regions (the primary somatosensory cortex and primary insula taste cortex).
TAKEAWAY:
- The perceived intensity of sweetness was comparable between the control group and the bariatric surgery group both before and after surgery.
- In the bariatric surgery group, the average preferred sweet concentration decreased from 0.52 M before surgery to 0.29 M after surgery (P = .008).
- The fMRI analysis indicated that women showed a trend toward a higher reward response to 0.4 M sucrose before bariatric surgery than the control participants.
- The activation of the reward region in response to 0.4 M sucrose (but not 0.1 M) declined in the bariatric surgery group after surgery (P = .042).
IN PRACTICE:
“Our findings suggest that both the brain reward response to and subjective liking of an innately desirable taste decline following bariatric surgery,” the authors wrote.
SOURCE:
This study was led by Jonathan Alessi, Indiana University School of Medicine, Indianapolis, and published online in Obesity.
LIMITATIONS:
The study sample size was relatively small, and the duration of follow-up was short, with recruitment curtailed by the COVID-19 pandemic. This study did not assess the consumption of sugar or sweetened food, which could provide further insights into changes in the dietary behavior post-surgery. Participants included women only, and the findings could have been different if men were recruited.
DISCLOSURES:
This study was funded by the American Diabetes Association, Indiana Clinical and Translational Sciences Institute, and National Institute on Alcohol Abuse and Alcoholism. Three authors reported financial relationships with some pharmaceutical companies outside of this study.

Will New Obesity Drugs Make Bariatric Surgery Obsolete?
MADRID — In spirited presentations at the annual meeting of the European Association for the Study of Diabetes, Louis J. Aronne, MD, of Weill Cornell Medicine in New York City, made a compelling case that the next generation of obesity medications will make bariatric surgery obsolete, and Francesco Rubino, MD, of King’s College London in England, made an equally compelling case that they will not.
In fact, Dr. Rubino predicted that “metabolic” surgery — new nomenclature reflecting the power of surgery to reduce not only obesity, but also other metabolic conditions, over the long term — will continue and could even increase in years to come.
‘Medical Treatment Will Dominate’
“Obesity treatment is the superhero of treating metabolic disease because it can defeat all of the bad guys at once, not just one, like the other treatments,” Dr. Aronne told meeting attendees. “If you treat somebody’s cholesterol, you’re just treating their cholesterol, and you may actually increase their risk of developing type 2 diabetes (T2D). You treat their blood pressure, you don’t treat their glucose and you don’t treat their lipids — the list goes on and on and on. But by treating obesity, if you can get enough weight loss, you can get all those things at once.”
He pointed to the SELECT trial, which showed that treating obesity with a glucagon-like peptide 1 receptor agonist reduced major adverse cardiovascular events as well as death from any cause, results in line with those from other modes of treatment for cardiovascular disease (CVD) or lipid lowering, he said. “But we get much more with these drugs, including positive effects on heart failure, chronic kidney disease, and a 73% reduction in T2D. So, we’re now on the verge of a major change in the way we manage metabolic disease.”
Dr. Aronne drew a parallel between treating obesity and the historic way of treating hypertension. Years ago, he said, “we waited too long to treat people. We waited until they had severe hypertension that in many cases was irreversible. What would you prefer to do now for obesity — have the patient lose weight with a medicine that is proven to reduce complications or wait until they develop diabetes, high blood pressure, heart disease and then have them undergo surgery to treat that?”
Looking ahead, “the trend could be to treat obesity before it gets out of hand,” he suggested. Treatment might start in people with a body mass index (BMI) of 27 kg/m2, who would be treated to a target BMI of 25. “That’s only a 10% or so change, but our goal would be to keep them in the normal range so they never go above that target. In fact, I think we’re going to be looking at people with severe obesity in a few years and saying, ‘I can’t believe someone didn’t treat that guy earlier.’ What’s going to happen to bariatric surgery if no one gets to a higher weight?”
The plethora of current weight-loss drugs and the large group on the horizon mean that if someone doesn’t respond to one drug, there will be plenty of other choices, Dr. Aronne continued. People will be referred for surgery, but possibly only after they’ve not responded to medical treatment — or just the opposite. “In the United States, it’s much cheaper to have surgery, and I bet the insurance companies are going to make people have surgery before they can get the medicines,” he acknowledged.
A recent report from Morgan Stanley suggests that the global market for the newer weight-loss drugs could increase by 15-fold over the next 5 years as their benefits expand beyond weight loss and that as much as 9% of the US population will be taking the drugs by 2035, Dr. Aronne said, adding that he thinks 9% is an underestimate. By contrast, the number of patients treated by his team’s surgical program is down about 20%.
“I think it’s very clear that medical treatment is going to dominate,” he concluded. “But, it’s also possible that surgery could go up because so many people are going to be coming for medical therapy that we may wind up referring more for surgical therapy.”
‘Surgery Is Saving Lives’
Dr. Rubino is convinced that anti-obesity drugs will not make surgery obsolete, “but it will not be business as usual,” he told meeting attendees. “In fact, I think these drugs will expedite a process that is already ongoing — a transformation of bariatric into metabolic surgery.”
“Bariatric surgery will go down in history as one of the biggest missed opportunities that we, as medical professionals, have seen over the past many years,” he said. “It has been shown beyond any doubt to reduce all-cause mortality — in other words, it saves lives,” and it’s also cost effective and improves quality of life. Yet, fewer than 1% of people globally who meet the criteria actually get the surgery.
Many clinicians don’t inform patients about the treatment and don’t refer them for it, he said. “That would be equivalent to having surgery for CVD [cardiovascular disease], cancer, or other important diseases available but not being accessed as they should be.”
A big reason for the dearth of procedures is that people have unrealistic expectations about diet and exercise interventions for weight loss, he said. His team’s survey, presented at the 26th World Congress of the International Federation for the Surgery of Obesity and Metabolic Disorders, showed that 43% of respondents believed diet and exercise was the best treatment for severe obesity (BMI > 35). A more recent survey asked which among several choices was the most effective weight-loss intervention, and again a large proportion “believed wrongly that diet and exercise is most effective — more so than drugs or surgery — despite plenty of evidence that this is not the case.”
In this context, he said, “any surgery, no matter how safe or effective, would never be very popular.” If obesity is viewed as a modifiable risk factor, patients may say they’ll think about it for 6 months. In contrast, “nobody will tell you ‘I will think about it’ if you tell them they need gallbladder surgery to get rid of gallstone pain.”
Although drugs are available to treat obesity, none of them are curative, and if they’re stopped, the weight comes back, Dr. Rubino pointed out. “Efficacy of drugs is measured in weeks or months, whereas efficacy of surgery is measured in decades of durability — in the case of bariatric surgery, 10-20 years. That’s why bariatric surgery will remain an option,” he said. “It’s not just preventing disease, it’s resolving ongoing disease.”
Furthermore, bariatric surgery is showing value for people with established T2D, whereas in the past, it was mainly considered to be a weight-loss intervention for younger, healthier patients, he said. “In my practice, we’re operating more often in people with T2D, even those at higher risk for anesthesia and surgery — eg, patients with heart failure, chronic kidney disease, on dialysis — and we’re still able to maintain the same safety with minimally invasive laparoscopic surgery that we had with healthier patients.”
A vote held at the end of the session revealed that the audience was split about half and half in favor of drugs making bariatric surgery obsolete or not.
“I think we may have to duke it out now,” Dr. Aronne quipped.
Dr. Aronne disclosed being a consultant, speaker, and adviser for and receiving research support from Altimmune, Amgen, AstraZeneca, Eli Lilly, Intellihealth, Janssen, Novo Nordisk, Pfizer, Senda, UnitedHealth Group, Versanis, and others; he has ownership interests in ERX, Intellihealth, Jamieson, Kallyope, Skye Bioscience, Veru, and others; and he is on the board of directors of ERX, Jamieson Wellness, and Intellihealth/FlyteHealth. Dr. Rubino disclosed receiving research and educational grants from Novo Nordisk, Ethicon, and Medtronic; he is on the scientific advisory board/data safety advisory board for Keyron, Morphic Medical, and GT Metabolic Solutions; he receives speaking honoraria from Medtronic, Ethicon, Novo Nordisk, and Eli Lilly; and he is president of the nonprofit Metabolic Health Institute.

GI-Targeted Bitter Hop Extract Curbs Hunger, Food Cravings
TOPLINE:
METHODOLOGY:
- Researchers conducted a randomized, double-blind, crossover study with 30 normal-weight women ages 18-40 with BMIs of 18.5-25. The trial design was similar to that used previously to test the intervention among men.
- Participants engaged in a water-only fast for 24 hours (6 p.m. to 6 p.m.) on three occasions and were given an ad libitum meal to break each fast.
- Participants were randomly assigned to one of three treatments: placebo, a high-dose (500 mg) bitter hop–based appetite suppressant (Amarasate), or a low dose (250 mg) of the appetite suppressant.
- Treatment capsules of half the total dose were given twice daily (16 hours and 20 hours into the fast).
- Participants recorded their subjective feelings about appetite and food cravings using a visual analog scale at 30-minute intervals starting 16 hours into the fast.
TAKEAWAY:
- Both the high-dose and low-dose treatment groups experienced a significant reduction in appetite (ie, hunger, fullness, satisfaction, thoughts of food) and food cravings compared with the placebo group.
- Energy intake at the ad libitum meal was 14.3% lower in the high-dose group than the placebo group (P < .05). It was 8.1% lower in the low-dose group, but the difference was not statistically significant.
- In the high-dose group, two participants reported loose stools and one reported heartburn. In the low-dose group, one participant reported loose stools.
IN PRACTICE:
“These data suggest that appetite suppressant co-therapy may be useful in reducing hunger during fasting in women and show that gastrointestinal delivery of bitter compounds may also be an effective method of reducing cravings for food,” the authors wrote.
SOURCE:
The study, led by Edward Walker, PhD, of the New Zealand Institute for Plant and Food Research Limited, Auckland, New Zealand, was published online in Obesity Pillars.
LIMITATIONS:
The study has limitations that affect its application for weight management. First, the study included only normal-weight individuals, which limits extension of the results for weight loss treatments. Second, it involved acute fasting and does not assess any accommodation to the intervention that may occur over longer-term use. An additional limitation is the small number of participants.
DISCLOSURES:
The research was funded by Calocurb Limited. The article processing charge was funded by the New Zealand Institute for Plant and Food Research Limited, a New Zealand government–owned Crown Research Institute. The authors declare no competing financial interests. The New Zealand Institute for Plant and Food Research Limited has licensed a hop extract as a dietary supplement to Calocurb to commercialize and currently holds a minor shareholding in this company.

‘Remarkable’ Weight Loss Seen With Safe, Tolerable Novel Oral Combination
MADRID — Amycretin, a dual-pathway, oral weight loss drug, led to up to 13% body weight loss in participants with overweight or obesity according to phase 1, first-in-human study data presented at the European Association for the Study of Diabetes (EASD) 2024 annual meeting.
Body weight loss was “remarkable for an orally delivered biologic,” said Agnes Gasiorek, PhD, senior clinical pharmacology specialist at Novo Nordisk, Måløv, Denmark, who presented the results. And “there was no plateauing of weight loss in the treatment period.”
With respect to the primary endpoint, stepwise dose escalation demonstrated that all tested dose levels up to and including 2 × 50 mg over a 12-week escalation period were safe and tolerable, Dr. Gasiorek reported.
The adverse events were in line with what was expected from targeting these receptors, and no new safety signals appeared during the study, she added.
Dual Pathways
Amycretin is a novel protein-based unimolecular amylin combined with a glucagon-like peptide 1 receptor agonist (GLP-1 RA) and is the first oral formulation of this combination under development.
The two components are both known to reduce appetite and energy intake and increase satiety, said Dr. Gasiorek, but amylin is considered to potentially increase leptin sensitivity and GLP-1 RAs are known to increase insulin secretion and biosynthesis. Together, the two components improve insulin sensitivity, decrease glucagon secretion, and lead to acute delay in gastric emptying.
The single-center, placebo-controlled, double-blind phase 1 study enrolled men and women aged 18-55 years (mean, 38-42 years across groups) with a body mass index of 25.0-39.9, without diabetes, and considered otherwise healthy.
Participants were randomly assigned to receive to receive oral amycretin (n = 95) or placebo (n = 29) once a day for up to 12 weeks. Study arms comprised single-ascending dosing (increasing from 1 mg/d to 25 mg), and multiple-ascending dosing. The latter consisted of multiple ascending doses (from 3 to 12 mg) over 10 days and multiple ascending doses (stepwise dose escalation, from 3 mg up to a final dose of 2 × 50 mg) over 12 weeks.
In her presentation at the EASD meeting, Dr. Gasiorek focused on results of the 12-week multiple ascending dose schedule with amycretin 50 mg (n = 16), amycretin 2 × 50 mg (n = 16), and placebo (n = 12).
The primary endpoint of the study was the number of treatment-emergent adverse events, while the area under the amycretin plasma concentration time curve and the maximum plasma concentration of amycretin were secondary endpoints.
The researchers also added percentage change in body weight after 12 weeks of treatment as an exploratory endpoint.
Safety Findings of Multiple Dosing
A total of 242 treatment-emergent adverse events were reported in the combined active and placebo groups and were of mild to moderate severity.
Treatment-emergent adverse events were found in 75% of the amycretin 50 mg group, 93.8% of the amycretin 2 × 50 mg group, and 33.3% of placebo recipients.
“Most adverse events reported were mild to moderate in severity and related to gastrointestinal discomfort (nausea and vomiting) and occurred in a dose-proportional manner,” reported Dr. Gasiorek.
Gastrointestinal events were experienced by 50%, 87.5%, and 16.7% of participants receiving amycretin 50 mg, amycretin 2 × 50 mg, and placebo, respectively (112 in total).
Decreased appetite was also found in 56.3%, 81.3%, and 16.7% of the amycretin 50 mg, amycretin 2 × 50 mg, and placebo groups, respectively.
Two serious adverse events occurred, one of which was acute cholecystitis and the other diabetic ketoacidosis; “however, the [latter] participant was found to have autoantibodies for beta cells before treatment and was later diagnosed with type 1 diabetes,” Dr. Gasiorek said.
Body Weight Reduction
Participants on 50 mg amycretin lost an average of 10.4% of their body weight (estimated treatment difference vs placebo, –9.2; 95% CI, –12.0 to –6.5), whereas those on 2 × 50 mg amycretin lost 13.1% of their body weight (estimated treatment difference vs placebo, –11.8; 95% CI, –14.6 to –9.0). Placebo group participants lost 1.2% of their body weight over the 12 weeks.
Although no plateauing of weight loss was seen, said Dr. Gasiorek, it is important to consider the relatively short treatment duration and the limited time on the final dose, which could potentially introduce bias.
To date, weight loss medications based on GLP-1 RA technology are injectables. A combination of the injectable amylin analogue cagrilintide and the GLP-1 RA semaglutide is also being explored as a subcutaneous treatment solution.
In a comment, Martin Holst Lange, MD, PhD, executive vice president of development at Novo Nordisk, said that “amycretin is the first treatment to harness the two distinct biological pathways stimulated by amylin and GLP-1 in a single molecule.”
The safety and tolerability profiles and the magnitude of weight loss support further development of amycretin in patients with overweight or obesity, said Dr. Lange, who noted that the company was awaiting data from the ongoing phase 1 trial with subcutaneous amycretin, expected in 2025.
Having heard the presentation, co-moderator Timo Müller, PhD, professor at Ludwig Maximilian University of Munich, Germany, gave a considered response. “The drug was relatively well tolerated, with the typical GLP-1–induced GI [gastrointestinal] adverse effects being the most frequently reported.”
But he pointed out that questions remain. “We still need to know whether, at the given dose, the drug outperforms best-in-class drugs like semaglutide or tirzepatide at the highest approved doses. Furthermore, it warrants clarification if and to what extent the activation of the amylin receptor contributes to the shown effect and if and to what extent the glycemic benefits result from activation of the glucagon receptor (amylin improved glycemia by decreasing the secretion of glucagon). In any way, the current data remain friendly and support phase 2 development.”
Oral Meds Could Bring Down Cost
Commenting on the data, Nerys Astbury, PhD, associate professor of diet and obesity at Nuffield Department of Primary Health Care Sciences, University of Oxford, England, said, “It is important to note that whilst the participants in this trial did lose weight over the 12-week study — and this was statistically more weight than in the placebo group — this study was not designed or powered to detect differences in body weight over longer periods of time.”
If the results are confirmed in future studies, amycretin might widen the treatment options and introduce competition, probably bringing down the costs in the longer-term, said Dr. Astbury, who welcomes the prospect.
“It is possible that some people might find the oral medications more acceptable than the injectable GLP-1 agonists currently available,” she said. And the current options are expensive, “which raises challenges to a taxpayer-funded health system like the NHS [National Health Service].”
“Furthermore, if the growing number of oral obesity medications prove safe, tolerable, and effective ... they are likely to significantly reduce the risks of developing many complications of obesity.”
Naveed Sattar, MD, professor of cardiometabolic medicine and honorary consultant, University of Glasgow, Scotland, agreed. “The more medicines coming forward to treat obesity, the better,” he said. In particular, oral medications would be more easily available, and cheaper, “for the many millions around the world struggling with obesity and its complications.”
Dr. Gasiorek declares she is an employee of and a shareholder in Novo Nordisk. Dr. Astbury declares no financial disclosures. Dr. Sattar declares having consulted for several companies that make diabetes medicines but also contributed to several lifestyle trials. For Novo Nordisk, he has consulted for the company on advisory boards, but not on any of their weight loss drug trial committees, and he is on the steering committee for the ZEUS trial, which is not a weight loss trial product but an anti-inflammatory. He does not have any shares for any product in health etc. He declares consulting fees and/or speaker honoraria from Abbott Laboratories, Afimmune, Amgen, AstraZeneca, Boehringer Ingelheim, Eli Lilly, Hanmi Pharmaceuticals, Janssen, Merck Sharp & Dohme, Novartis, Novo Nordisk, Pfizer, and Sanofi, and grant support paid to his university from AstraZeneca, Boehringer Ingelheim, Novartis, and Roche Diagnostics. Dr. Müller received financial support or an honorarium from Novo Nordisk, Merck, Eli Lilly, Boehringer Ingelheim, and Mercodia; he further holds stocks at Novo Nordisk and Eli Lilly and is cofounder of Bluewater Biosciences.

“Furthermore, if the growing number of oral obesity medications prove safe, tolerable, and effective ... they are likely to significantly reduce the risks of developing many complications of obesity.”
Naveed Sattar, MD, professor of cardiometabolic medicine and honorary consultant, University of Glasgow, Scotland, agreed. “The more medicines coming forward to treat obesity, the better,” he said. In particular, oral medications would be more easily available, and cheaper, “for the many millions around the world struggling with obesity and its complications.”
Dr. Gasiorek declares she is an employee of and a shareholder in Novo Nordisk. Dr. Astbury declares no financial disclosures. Dr. Sattar declares having consulted for several companies that make diabetes medicines but also contributed to several lifestyle trials. For Novo Nordisk, he has consulted for the company on advisory boards, but not on any of their weight loss drug trial committees, and he is on the steering committee for the ZEUS trial, which is not a weight loss trial product but an anti-inflammatory. He does not have any shares for any product in health etc. He declares consulting fees and/or speaker honoraria from Abbott Laboratories, Afimmune, Amgen, AstraZeneca, Boehringer Ingelheim, Eli Lilly, Hanmi Pharmaceuticals, Janssen, Merck Sharp & Dohme, Novartis, Novo Nordisk, Pfizer, and Sanofi, and grant support paid to his university from AstraZeneca, Boehringer Ingelheim, Novartis, and Roche Diagnostics. Dr. Müller received financial support or an honorarium from Novo Nordisk, Merck, Eli Lilly, Boehringer Ingelheim, and Mercodia; he further holds stocks at Novo Nordisk and Eli Lilly and is cofounder of Bluewater Biosciences.

Genitourinary Symptoms in Men: Canaries in the Coal Mine for Underlying Chronic Disease
At age 57, a senior scientific researcher in Santa Barbara, California, complained of chronic erectile dysfunction (ED) in what had been a sexually active marriage. “I just couldn’t get an erection, let alone sustain one. Apart from that, I maybe felt a bit tired but generally okay,” he said. Though seemingly well otherwise, 18 months later he was dead of a hereditary right-sided colon cancer.
While not all cases of ED are associated with a dire outcome, the genitourinary signals of ED and lower urinary tract symptoms (LUTS), especially nocturia, serve as sentinel indicators of the presence of, or risk factors for, serious chronic conditions. These commonly include cardiovascular disease (CVD), diabetes, and metabolic syndrome and are associated with obesity, depression, and obstructive sleep apnea.
Sometimes these serious conditions may stay under the radar until men seek help for ED or LUTS.
“We know that among men who had a heart attack, 50% had some degree of ED within 3 years of their cardiac event,” Sam Tafari, MBBS, of the Endocrine and Metabolic Unit at Royal Adelaide Hospital in Adelaide, South Australia, said in an interview.
That’s the bad news. The good news is that these two problems may specifically incentivize men to seek timely care for serious conditions they might otherwise not get, according to Dr. Tafari. And primary care doctors are ideally positioned to get men early multifaceted care. He recently coauthored a call to action on this issue in a review appearing in the Journal of Men’s Health.
In Dr. Tafari’s experience, most patients seeking urological care are unaware of the multiple conditions linked to ED and LUTS. “Many consider these to be due to issues like low testosterone, which actually make up a very small proportion of cases of ED,” he said. Aging, obesity, inactivity, smoking, alcohol abuse, and prescription and street drugs can also contribute to the development of ED.
In most affected men, ED is of vascular etiology, with endothelial dysfunction of the inner lining of blood vessels and smooth muscle the common denominator.
This dysfunction causes inadequate blood supply to both the coronary and the penile arteries, so ED and CVD are considered different manifestations of the same systemic disorder. Because the tumescence-controlling cavernosal vessels of the penis are considerably smaller, the same level of arteriopathy causes a more severe reduction in blood in the erectile tissue. As a result, ED often precedes CVD and presents an early opportunity to screen men for CVD.
As to the mechanisms behind LUTS, Peter N. Tsambarlis, MD, a urologist at Northwestern Medicine in Chicago, subscribes to the inflammation theory. “Suboptimal health issues such as high [blood] pressure, blood lipids, and blood glucose lead to chronic widespread inflammation, which makes the bladder less flexible as a storage vessel,” he explained. “It’s not able to stretch adequately overnight to hold the urine until morning.”
Ask Early, Ask Often
Jeffrey P. Weiss, MD, PhD, chair of the Department of Urology at SUNY Downstate Health Sciences University in Brooklyn, New York, has done research that uncovered a relationship between structural cardiac disease and nocturia. “So if you had to ask a patient a single question that would point to a global health issue, it would be ‘Do you have frequent nighttime urination,’ ” he said.
It’s never too soon to ask men about these symptoms, said Dr. Tsambarlis. The best time to raise issues of ED and LUTS is when a man enters primary care — regardless of age or absence of symptoms. “That way you have a baseline and can watch for changes and do early intervention as needed. Men don’t usually want to bring up sexual dysfunction or urinary health, but asking doesn’t need to dominate the visit,” he said.
Dr. Tafari recommends that primary care physicians adopt a targeted approach using ED and nocturia as entry points for engaging men in their healthcare. While acknowledging that primary care physicians have an ever-growing checklist of questions to ask patients and hardly need one more thing to screen for, he suggests asking two quick, and easy “before you go” genitourinary queries:
- Are you having trouble with erections or having sex?
- Are you getting up at night to pass urine more than once?
“The men really appreciate being asked,” he said. “But what worries me is all the men we don’t see who have these symptoms but don’t know they’re important, and no one is asking about them.”
Gideon Richards, MD, a urologist at the Northwell Health Physician Partners Smith Institute for Urology at Garden City, and director of Men’s Health, Central Region, for Northwell Health in New Hyde Park, both in New York, said erectile problems should not wait for specialty care. By the time men with ED are referred to urology, they may already have failed treatment with first-line phosphodiesterase 5 inhibitor therapy, he said. “A significant proportion will have arteriogenic erectile dysfunction, a measurable decrease in the amount of blood flow into the erectile bodies.”
Addressing the Issue
Addressing genitourinary-signaled issues has the double benefit of easing ED and LUTS and improving men’s health and longevity and may help narrow the worldwide gender gap in life expectancy. As a recent global analysis found, there’s a 5-year longevity disparity favoring women over men. Biology aside, men do not access healthcare as often as women, who consult their general practitioners regularly throughout their lifespan for multiple reasons, including reproductive care, and more screening programs are aimed at women.
Added Dr. Tsambarlis, “Men should know that losing weight and switching to a healthy lifestyle can improve sexual function about half as much as phosphodiesterase 5 inhibitors such as sildenafil [Viagra] or tadalafil [Cialis].”
“Many, however, would prefer just to take drugs rather than change their lifestyle and lose weight. There are certainly effective options available, but these are not uniformly effective,” said Dr. Weiss.
Dr. Tafari’s group is designing a short, simple, culturally acceptable screening tool for use in primary care practice and will monitor its impact on physician prescribing habits and overall men’s health outcomes.
Dr. Tafari received funding from the Hospital Research Foundation and Freemasons Centre for Male Health and Wellbeing in Adelaide, South Australia. Dr. Tafari, Dr. Tsambarlis, Dr. Weiss, and Dr. Richards had no relevant conflicts of interest to declare.
