A person posted that they stopped taking semaglutide (the drug in Ozempic/Wegovy) because of nonstop diarrhea and burping, and about 12 days after their last injection they began having chest pains that feel like trapped burps in the upper chest. They went to the emergency room; their EKG and blood tests were normal. They’re asking if others have had the same terrible gas buildup and saying over-the-counter remedies haven’t helped. Semaglutide is a drug that mimics a natural gut hormone involved in appetite and digestion. People use it for diabetes and for weight loss. One of its effects is to slow how quickly the stomach empties and to change gut motility (how food and gas move through the digestive tract). That can reduce hunger for many people, but it also commonly causes gastrointestinal side effects like nausea, diarrhea, burping, bloating and constipation in some users. What the little report shows is a single-person experience — an anecdote, not a controlled study. The timeline fits with known semaglutide effects: side effects often appear while taking the drug and can persist for days to weeks after stopping, because the drug stays in the body for a while. Trapped gas, burping, bloating and chest discomfort are plausible outcomes from slowed or uncoordinated stomach and gut movements. However, a normal EKG and bloodwork at the ER are reassuring that there was no immediate heart attack or major abnormality, but they don’t fully rule out other causes of chest pain. This isn’t evidence that everyone will get the same problem; it’s one report that aligns with known side effects and the drug’s long half-life. Why this matters: lots of people are on semaglutide for weight loss or diabetes, and gastrointestinal side effects are common enough to influence whether someone continues the drug. If you experience severe, persistent bloating, chest pressure, or pain after starting or stopping semaglutide, you should take it seriously and seek medical care to rule out heart or other urgent causes. For many people, these symptoms can be managed by medical advice, dose adjustment, slower titration, or switching therapies. It’s also a reminder that stopping a long-acting drug doesn’t always make side effects disappear immediately. Caveats and risks: this is a single anecdote, not a study, so we can’t say how often this happens or whom it will affect. Semaglutide can cause serious side effects in some people (like pancreatitis or gallbladder issues), and chest pain should never be ignored — emergency evaluation is appropriate when chest pain occurs. People with known heart conditions, severe abdominal pain, or signs of allergic reaction should contact a doctor promptly. If over-the-counter remedies don’t help trapped gas or bloating, a healthcare provider can suggest other medications or tests. Finally, don’t restart or stop prescription medication without discussing it with the prescriber; they can help balance benefits, side effects, and timing. Bottom line: trapped gas and chest discomfort after stopping semaglutide are plausible and have been reported anecdotally, but a single account can’t prove commonality — get medical evaluation for chest pain and talk to your prescriber about next steps.
