Why do I have sulfur burps on Wegovy?

Semaglutide slows gastric emptying — food stays в the stomach 2-4x longer than normal. This delayed transit lets gut bacteria ferment sulfur-containing proteins (eggs, meat, dairy, garlic, cruciferous vegetables), producing hydrogen sulfide gas. The "rotten egg" smell is the result. Mitigation: smaller meals, lower-sulfur protein sources (poultry, fish), avoid garlic/onions/eggs first 4 weeks, peppermint tea after meals. Persists past 12 weeks? Talk к your prescriber about anti-nausea support or slower titration. Not dangerous but socially disruptive.
