Role of GLP-1 Receptor Agonists for Weight Loss

This Harvard Medical School Continuing Education video examines these key questions: What role do GLP1 receptor agonists (GLP1 RA) play in weight loss? What are the risks and benefits of using GLP1 RA for weight loss?

Lee-Shing Chang, MD, an endocrinologist at Brigham and Women’s Hospital, identifies FDA-approved medications for weight loss and explains GLP1 and the role GLP1 receptor agonists play in weight management. Key studies including the SCALE and STEP trials are highlighted and the efficacy of the GLP-1 receptor agonists liraglutide and semaglutide are compared.
