GLP-1 receptor agonists (semaglutide, tirzepatide) are highly effective pharmacologic interventions for obesity, producing significant weight loss and metabolic improvements, but their rapid expansion raises safety concerns regarding gastrointestinal side effects, rare serious adverse events, and long-term outcomes not captured in clinical trials.

GLP-1 medications like semaglutide and tirzepatide are currently the most effective non-surgical treatments for obesity, offering weight loss comparable to surgery for many. However, they are not without risks, including common gastrointestinal issues and rare serious side effects. It is crucial to use these medications under strict medical supervision, especially if you have other health conditions, to manage side effects and monitor for long-term safety.
