A person posted that after about a month on semaglutide they’ve lost weight but are getting very foul-smelling burps. They asked if others had the same thing and how to stop it. This is a single-person anecdote from an online forum, not a controlled study. Semaglutide is the drug in brand names like Ozempic and Wegovy. It’s a synthetic version of a hormone your gut makes that helps control appetite and digestion. In simple terms, it tells your brain you’re less hungry and slows how quickly your stomach empties. Doctors prescribe it for type 2 diabetes and for weight loss in certain people. What this post reports is a user experience — one person with a noticeable side effect. There are lots of reports online of changes in digestion on semaglutide, including nausea, gas, burping, constipation, or diarrhea. Clinical trials list nausea and vomiting among common side effects, and slower stomach emptying is a known effect, which can change how food and gas move. But a single anecdote about “very foul burps” can’t tell us how common that exact symptom is, how long it lasts, or whether it’s caused by the drug or by diet changes people often make when losing weight. For someone taking semaglutide, this matters because digestive side effects can affect quality of life and social situations. If you’re considering the drug for weight loss or diabetes control, expect possible GI (gastrointestinal) changes — often temporary — and plan for ways to manage them. People who already have digestive issues, or who take other medications that affect the stomach, may notice more or different symptoms and should talk to their clinician. Caveats: this post isn’t medical evidence. Side effects vary by person, dose, and what else someone is eating or doing. If burping is severe, unusually foul, comes with fever, severe abdominal pain, weight loss beyond intended, or lasts a long time, see a doctor — those signs could mean something else. Don’t stop or start prescriptions without talking to your provider. Finally, semaglutide is a prescription medication with known side effects; it’s regulated and should be used under medical supervision. Bottom line: foul burps are a plausible side effect of semaglutide because the drug changes stomach function, but one forum report can’t tell you how likely it is or how long it will last — ask your clinician if it’s bothering you.
