Can Ozempic, Wegovy or Mounjaro trigger or worsen an eating disorder? Possibly, in people who are already vulnerable. A report published on 30 October 2026 by MIT Technology Review says clinicians are seeing GLP-1 drugs misused to lose weight faster and more severely, and a same-day Psychiatric Times interview with a leading eating disorder psychologist stresses that these medicines are contraindicated for people with anorexia or bulimia. If you or someone in your family has a history of disordered eating, speak to a doctor before starting any GLP-1 medicine.
What Happened
The MIT Technology Review report brings together data and clinician accounts. It cites a JAMA Psychiatry study showing that the global rate of anorexia and bulimia rose 71% between 1990 and 2023, with about 18.1 million people affected in 2023 and a projection of 21.8 million by 2050. In a small study mentioned in the report, around 30% of people with eating disorders had used GLP-1 drugs and roughly 10% appeared to have misused them. The clinician who led that study believes the real figure is higher.
Doctors also report that some patients now arrive at a more advanced stage of illness, and that eating disorders are appearing at younger ages. Some teenagers, reportedly as young as 11 in the United States, obtained these drugs through social media. Social media itself, which pushes extreme diet and body content, is named as another factor.
The Psychiatric Times interview is expert commentary rather than a new trial. It explains that GLP-1 medicines slow stomach emptying and may dull appetite and the reward from food. For someone with anorexia, this can reinforce restriction and the drive to be thinner. For someone with binge eating disorder, early studies show fewer binges, but long-term results and what happens after stopping have not been studied.

GLP-1 use in India is growing quickly as semaglutide and tirzepatide become easier to buy, and prices are falling. Weight-loss injections are discussed openly on Instagram and YouTube, and many young people want a quick route to a thinner body. Eating disorders in India are often missed. A young woman who is skipping meals, exercising excessively or constantly talking about her weight may be seen as just being health conscious. Families may not realise there is a medical problem until weight loss is severe.
Medicines bought without a prescription, from a pharmacy counter, a gym or an online seller, carry the greatest risk, because nobody checks whether the person is a suitable candidate. These drugs are meant for adults with obesity or diabetes under medical supervision, not for people who are already at a normal weight and want to become thinner.
Warning Signs to Watch For
Doctors suggest families and patients look out for these signs: weight loss much faster than expected, skipping meals or eating very little even when not nauseous, vomiting or other purging after eating, excessive exercise, growing preoccupation with food and weight rather than less, and a goal weight that keeps getting lower. Dizziness, fainting, hair fall, missed periods and weakness are also red flags that need prompt medical attention.
What To Do Next
If you are considering a GLP-1 medicine, tell your doctor honestly about any past or present eating disorder, crash dieting, purging or binge eating. A good clinician will ask about this before prescribing, and screening is exactly what experts now recommend. During treatment, aim for adequate protein, regular meals, non-restrictive calorie targets and strength exercise, rather than eating as little as possible. If following this advice feels very difficult, or you feel fear or guilt around food, tell your doctor early.

If you suspect a family member is using these injections to lose weight in an unhealthy way, approach them with care rather than blame, and arrange a medical review with a doctor, ideally together with a nutritionist or mental health professional. Do not stop or start any medicine on your own advice from social media.
For adults with genuine medical need, GLP-1 therapy remains an effective and well-studied option when prescribed after proper screening and followed up regularly. The point of this news is not that the medicines are unsafe for everyone, but that the right patient selection and monitoring matter.
