You noticed the scale moving. That part felt good. But then things slowed down. A lot.
Constipation is one of the most common side effects people experience with GLP-1 medications like semaglutide and tirzepatide. Many people are not warned about it ahead of time. And when it happens, it can feel uncomfortable and confusing.
The good news: there are simple fixes. Most people find relief by making small changes to what they eat, drink, and do each day.
This post explains why it happens and what to do about constipation step by step.
Struggling with side effects? Your care team is here to help.
GLP-1 medications work partly by slowing down digestion. This is actually a good thing for weight loss. It helps you feel full longer. But it also means food moves through your body more slowly than before.
When food moves slowly, your large intestine absorbs more water from it. That can make stool harder and more difficult to pass.
It is not a sign something is wrong. It is a known side effect, and it is manageable.
According to research, constipation affects a significant number of people who use semaglutide.
Start here. These are often the initial steps care teams recommend.
Many people on GLP-1s are not drinking enough water. Aim for at least 8 cups of water per day, or more if you are active or live somewhere warm.
Dehydration is one of the top causes of constipation. Water helps keep stool soft and easy to move.
Fiber helps your gut move things along. But adding too much too fast can cause bloating and gas.
Start with one extra serving of a high-fiber food each day. Give your body a few days to adjust before adding more.
A short walk after meals can help wake up your digestive system.
Even 10 to 15 minutes of gentle movement can make a difference. You do not need to do anything intense.
GLP-1s reduce appetite. That means many people eat less or even skip meals. But eating too little can slow digestion even more.
Try to eat at regular times each day, even if portions are small.
Over-the-counter stool softeners can help in the short term. They tend to be gentle and non-habit-forming.
Talk to your licensed healthcare provider before starting any new supplement or medication, even one that seems minor.
The answer depends on your body and what you are eating now. Most adults need 25 to 38 grams of fiber per day. Many people get far less than that.
A simple goal: add 1 to 2 servings of high-fiber food per day and see how your body responds.
For water, the general guidance from the National Academies of Sciences is about 2.7 liters (91 oz) per day for women from all sources, including food.
If you are not hitting those numbers, start there before trying anything else.
