Someone who used Wegovy (a brand of the weight-loss drug semaglutide) for four months reported that a month after stopping the medication they have persistent diarrhea. They said they only reached a 1 mg dose, felt unwell while on the drug with alternating constipation and diarrhea, and their digestion hasn't returned to normal since stopping. They asked about the ongoing diarrhea and what might be going on. Wegovy contains semaglutide, which is a man-made version of a natural hormone that helps control appetite and digestion. In simple terms, it signals the brain that you're full and it slows how fast your stomach empties. That slowing of digestion is one reason people feel less hungry and can lose weight on the drug. Semaglutide is given by weekly injection and is prescribed and regulated; it is not an over-the-counter pill. What the snippet shows is an individual report — a single person's experience — not a controlled study. Post-marketing reports and patient discussions sometimes mention gastrointestinal side effects like nausea, diarrhea, constipation, or stomach pain while taking semaglutide. Those problems commonly start while people are on the medicine and often improve after stopping, but some people describe lingering issues for weeks afterward. A single report can't tell us how common persistent diarrhea is or why it happens. To know that, we'd need larger studies or safety reports that specifically track symptoms after stopping treatment. Why this matters: digestive side effects are among the most frequent reasons people stop semaglutide or feel unhappy with it. If you or someone you know is considering or using Wegovy, it's useful to know that stomach upset can be part of the experience and that symptoms sometimes change during dose adjustments or after stopping. Persistent diarrhea can affect daily life, hydration, and nutrient balance, so it's not just an annoyance — it can be important to address with a clinician. Caveats and risks: this is anecdotal—one person's report—so it doesn't prove that Wegovy caused prolonged diarrhea in everyone. Other causes (infections, diet changes, other medicines, or unrelated digestive conditions) could also explain ongoing symptoms. Semaglutide and Wegovy are prescription drugs; any new, severe, or persistent side effects should prompt discussion with the prescriber or a healthcare professional. They can check for other causes, suggest treatments to manage symptoms, and decide whether further testing or referral is needed. If someone becomes dehydrated, has severe abdominal pain, blood in the stool, or weight loss they didn't intend, those are reasons to seek prompt care. Bottom line: ongoing diarrhea after stopping Wegovy is a reported experience, but a single report can't prove it's a common or permanent effect; talk to your doctor to rule out other causes and get help managing symptoms.
