If you've had burps that smell like rotten eggs since starting a GLP-1, you're not imagining it — "sulfur burps" are a real, if unpleasant, thing people report. The good news: they're usually harmless and often improve with a few simple changes. Here's the plain-English why and what to do.
Our GLP-1 Companion Guide puts the whole playbook in one place — side effects, hydration, and protein targets — with an Excel tracker so you can see what works.
Get the GLP-1 Companion guide on Etsy →GLP-1s slow stomach emptying, so food sits longer and slower digestion can produce hydrogen-sulfide gas, the rotten-egg smell. Heavy, high-fat meals make it more likely.
Smaller meals, easing up on very high-fat foods, staying hydrated and moving, and spacing meals out so the stomach can clear all help reduce them.
Usually they're harmless and diet-related. But burps with severe pain, persistent vomiting, or fever deserve prompt medical attention.
