Constipation is a common side effect of Wegovy, Ozempic and Zepbound. Here is why it happens, what usually helps, and when it needs medical attention.
It isn’t glamorous, but it’s one of the most searched GLP-1 side effects for a reason.
GLP-1s slow the movement of food through your gut. Add eating less, drinking less (because you’re not thirsty), and perhaps less fiber, and things can grind to a halt.
| Habit | Tip |
|---|---|
| Fluids | Keep a water bottle in sight. Sip through the day |
| Fiber, added slowly | Oats, beans, lentils, berries, pears, chia. Too much too fast can cause bloating |
| Movement | A daily walk helps your gut move |
| Routine | Give yourself unhurried time, often after breakfast |
| Don’t ignore the urge | Holding it in makes things worse |
Stool softeners, fiber supplements and gentle laxatives are widely used. Ask your pharmacist or prescriber which is right for you, especially if you take other medicines or have kidney problems.
Dehydration makes constipation worse, and GLP-1 labels warn that dehydration from vomiting or diarrhea can affect the kidneys. Drinking enough protects both.
A quick yes or no for “bowel movement today” plus fluids for a week gives your prescriber something concrete.
Rachel, 50, hasn’t had a bowel movement in four days and feels bloated. She realizes she’s drinking about two glasses of water a day since starting Wegovy. She adds a water bottle to her desk, oats and berries at breakfast, and a 20-minute walk after dinner. Things improve within a week. When they don’t fully, her pharmacist recommends a gentle option.
| Meal | Idea |
|---|---|
| Breakfast | Oats with berries and chia |
| Lunch | Lentil soup or a bean salad |
| Snack | A pear or a handful of almonds |
| Dinner | Vegetables with your protein |
Increase fiber gradually over a week or two, and drink more as you do.
Some people get diarrhea rather than constipation, especially after dose increases. Keep drinking fluids, and call your prescriber if it’s severe or lasts more than a couple of days, because dehydration can affect the kidneys.
Yes. It’s one of the most common side effects listed on semaglutide labels.
For many people it improves with time and good habits. If it doesn’t, tell your prescriber.
Many people use over-the-counter laxatives, but check with your pharmacist or prescriber first.
Usually it’s uncomfortable rather than dangerous. Severe pain, vomiting, or being unable to pass gas needs medical help right away.
Go more slowly rather than stopping, and drink more fluids. Ask your pharmacist if it continues.
