Now, with the rising popularity of medications like Ozempic for weight loss, she fears she will care for more teens with eating disorders who are seeking glucagon-like peptide 1 (GLP-1) agonists or who have developed a disorder while taking them.
“We haven’t seen patients yet, but I’m sure they are on their way,” said Dr. Dennis, a clinical assistant professor in the Department of Psychiatry at the University of Illinois College of Medicine in Chicago. She is also the cofounder and chief medical officer of SunCloud Health, an outpatient eating disorder treatment center in Illinois.
Dr. Dennis’ concerns reflect a growing unease among eating disorder specialists as obesity medications gain traction for adolescent use. A recent study published in JAMA Pediatrics showed nearly 80% of teens in treatment for obesity reported symptoms of disordered eating at the outset of an intervention. These included signs of binge eating and loss of control.
The randomized clinical trial, conducted from 2018 to 2023, examined 141 adolescents with obesity undergoing interventions like low-energy diets or intermittent energy restriction. Almost half scored as having risk for an undiagnosed eating disorder, as defined by the Eating Disorder Examination Questionnaire (EDE-Q).
At the end of the intervention, many teens continued to have symptoms of disordered eating, while a smaller group was newly scored as having a risk for an eating disorder.
Weight Loss and Eating Disorders: A Balancing Act
The findings illuminate a significant challenge for pediatricians and primary care clinicians: Balancing effective weight management with the risk of exacerbating or triggering eating disorders, said Hiba Jebeile, PhD, a research dietitian at The Children’s Hospital at Westmead in Australia, and the study’s lead author. Adding weight loss medication on top of the equation can further complicate care.
“It is helpful for obesity and eating disorder services to work together, with clear referral pathways, to manage these adolescents,” Dr. Jebeile said.
The US Food and Drug Administration approved semaglutide for weight loss in adolescents aged 12-17 years in December 2020. One study found that the number of adolescents prescribed GLP-1 receptor agonists (GLP-1 RAs) for type 2 diabetes and weight management rose from 8722 to 60,567 between 2020 and 2023 — a nearly sevenfold increase.
“The number of adolescents taking these medications is going up because they work,” said Suzanne Cuda, MD, medical director of Alamo City Healthy Kids and Families, a medical weight management clinic in San Antonio. The medications have been shown to treat type 2 diabetes, lower blood pressure, and reduce the risk for cardiovascular diseases.
“The younger you are, the better the outcome,” Dr. Cuda said.
How GLP-1 agonists may affect adolescents in the long run is not yet clear. Existing studies on GLP-1 medications in patients with eating disorders have shown mixed results. Some studies indicate that the drugs decrease binge episodes for those with binge eating disorder or bulimia nervosa. However, these studies had small sample sizes and measured only short-term effects, leaving long-term outcomes and risks unknown.
Traditional treatments for eating disorders emphasize regular eating patterns, body acceptance, addressing weight stigma, and improving attunement to hunger and fullness cues — approaches that may conflict with the effects of GLP-1 agonists. These drugs suppress appetite, alter metabolic signals, and may unintentionally reinforce weight loss as a primary goal, creating a potential disconnect between the aims of recovery from eating disorders and the biologic effects of the medication, experts said.
Dr. Cuda said she has cared for adolescents with diagnosed eating disorders in her practice who are seeking GLP-1 agonists. She said she first works with patients to treat the underlying disorder before prescribing medication.
“One of the concerns is the extreme reductions in calories that could be induced by GLP-1 RA in children and adolescents,” she said. Unlike adults, adolescents use caloric energy not just for physical activity but also for growing and developing, she said.
“They can’t catch up on that growth and development,” she added.
