People using weight-loss drugs are more likely to seek advice from social media than health care professionals, a Coventry University–led study has found. Researchers from the U.K. and Canada found that users of GLP-1 medications—weight-loss drugs such as Ozempic, Wegovy and Mounjaro that help regulate appetite and blood sugar levels—often rely on social media, online forums, friends and family for information about the drugs. Almost half (48%) of participants said social media was a source of information, while health care professionals were consulted less frequently.
The study was led by Dr. Jason Tallis, associate professor in Coventry University's Research Center for Discoveries in Life Sciences, and involved researchers from the university's Research Center for Healthcare and Community Transformation alongside academics from the University of Alberta, the University of Warwick, the University of Leicester, York St John University and University Hospitals Coventry and Warwickshire (UHCW) NHS Trust. The paper is published in the journal BMC Public Health.
The survey explored how people in the U.K. are using weight-loss medications. While satisfaction was high, with 93% of users reporting positive effects on body weight and 83% on appearance, researchers also identified potential challenges. Nearly two-thirds (62%) of participants reported skipping meals at least two or three times a week and reduced energy levels that affected physical activity or daily tasks, while more than 46% expressed concerns about the impact of the medications on muscle mass.
Researchers found many users were seeking practical advice about managing side effects such as nausea, fatigue and muscle loss, as well as longer-term concerns about maintaining weight loss and accessing medication in the future. Participants also discussed the psychological impact of treatment, including changes in confidence, body image and eating habits, with many turning to online communities for shared experiences and peer support.
Tallis said, "One of the most striking findings was the extent to which users relied on social media, friends, family and online forums for information, rather than health care professionals. Given the complexity of these medications and the potential for side effects, misuse and weight regain after stopping treatment, this suggests an important gap in evidence-based support."
The study also found that most participants obtained their medication through online pharmacies, with some raising concerns about the robustness of preprescription checks. A small proportion also reported taking higher doses or using the medication more frequently than recommended because they felt it was not working effectively.
Tallis said the findings highlight the need for better education and support to help people use weight-loss medications safely and effectively as demand continues to grow.
He said, "We hope this research helps shift the conversation from simply prescribing medication to supporting people through medication use. These drugs can be powerful tools, but people need clear guidance and practical support to stay active, maintain muscle health, manage side effects and sustain the benefits over time."
Professor David Broom, professor of health and physical activity at York St John University, added: "We are in a new age where weight-loss medications are readily accessible and are clearly very effective in the short term. However, there are serious concerns about people using them without appropriate checks, and there is a lack of long-term support when people stop using them."
