If things have slowed way down since starting Ozempic, Wegovy, Mounjaro, or Zepbound, you are not imagining it — constipation is one of the most commonly reported GLP-1 side effects. The good news: it is also one of the most manageable with a few simple food-and-habit changes. Here is the plain-English why and what to do.
Two everyday factors make it worse: because you are eating less food overall, you are often getting less fiber and less water than before — the exact two things that keep things moving. Both are very much in your control.
Our GLP-1 Companion Guide puts the whole side-effect playbook in one place — hydration, fiber, protein targets, and an Excel tracker so you can see what is (and isn't) working. No jargon, just what to do.

But call your prescriber for severe or worsening belly pain, vomiting, a hard/swollen abdomen, or several days with no bowel movement at all — those can signal something that needs medical attention.
Yes — it's one of the most common side effects, largely because these medications slow stomach and gut movement. It often eases as your body adjusts and as you add fiber and fluids.
Hydration plus a short walk is the simplest first step. Many people also discuss magnesium or a fiber supplement with their prescriber. Add fiber gradually to avoid bloating.
For severe pain, no bowel movement for several days, vomiting, or a hard, distended belly — those deserve prompt medical attention.
