A person who’s been taking Wegovy (a prescription weight-loss drug) posted about having repeated vomiting and “sulfur burps” after their weekly injections, and how they eventually figured out a way to stop it. They said the nausea and burping usually showed up two to three days after their roughly 1 mg weekly dose, and that it was a common complaint they saw in other people too. They found the side effect so upsetting that they nearly gave up the treatment, despite getting good weight-loss results otherwise. Wegovy’s active ingredient is semaglutide. That is a man-made version of a natural hormone your gut releases when you eat. Semaglutide tells the brain you’re less hungry and slows how fast your stomach empties, which helps some people eat less and lose weight. It’s given by weekly injection at doses that are higher than the versions approved only for diabetes treatment. This post is an individual’s experience, not a formal study. It’s basically a single-person report describing a pattern: nausea and sulfur-smelling burps a couple days after the shot, with vomiting in some episodes. The writer noticed the timing (a few days post-dose) and linked it to the dose size (around 1 mg weekly). They also said this side effect shows up commonly in online discussions, which matches clinical trial reports where nausea and vomiting are known side effects. But a personal report doesn’t tell us how often this happens across all users, exactly why it happens, or whether the fix they used will work for others. For people thinking about Wegovy or already using it, this matters because these unpleasant side effects can be a make-or-break issue. If you’re seeing weight loss benefits but are being knocked back by nausea, burping or vomiting, it’s worth knowing that others experience the same thing and that adjustments — like changing how you take food, splitting doses when advised, or talking to your clinician about dose timing — might help. It’s also a reminder to watch the timing of symptoms; if they reliably spike a few days after a shot, that pattern can guide conversations with your provider. There are important caveats. Individual anecdotes don’t replace medical guidance. Semaglutide and Wegovy are prescription drugs with known side effects including nausea, vomiting, diarrhea, constipation, and in rare cases more serious issues like pancreatitis (inflammation of the pancreas) or gallbladder problems. People with certain medical histories — for example, a personal or family history of a specific type of thyroid cancer — are usually advised not to take these drugs. If side effects are severe or persistent, stop the medication only under medical advice and seek care. Finally, the post doesn’t describe the specific tweak that fixed the problem in a verifiable way, so anyone tempted to try a similar fix should first check with their prescriber. Bottom line: vomiting after a Wegovy shot is a commonly reported issue; hearing how others managed it can help, but talk to your clinician before making changes.
