A systematic review and network meta-analysis of 39 studies (33,354 participants) assessed gastrointestinal adverse events of GLP-1 receptor agonists in non-diabetic patients with overweight or obesity. Nausea, vomiting, diarrhea, and constipation were the most common side effects. Orforglipron showed the highest nausea risk, followed by exenatide, tirzepatide, semaglutide, and liraglutide. The differing safety profiles can help clinicians tailor weight-loss therapy choices.
