Does Ozempic Cause Constipation or Diarrhea? Causes, Relief & What to Expect
Ozempic can affect your digestion in different ways. If you’re wondering, “Does Ozempic cause constipation or diarrhea?”, the answer is yes. Both can happen. According to FDA prescribing information, the most common gastrointestinal side effects include nausea, vomiting, diarrhea, abdominal pain, and constipation.These symptoms usually appear when starting the medication or increasing your dose. While uncomfortable, they are often temporary and improve as your body adjusts. Understanding why these changes happen and how to manage them can help you stay on track with treatment while protecting your gut health.
Why Ozempic Causes Constipation or Diarrhea?
Ozempic can cause both constipation and diarrhea because it slows digestion through delayed gastric emptying. This affects how food moves through the gut, leading to either slower stool movement (constipation) or excess water in the intestines (diarrhea). Ozempic contains semaglutide, a GLP-1 receptor agonist that directly affects your digestive system. According to MedlinePlus, semaglutide slows the emptying of the stomach and affects appetite and insulin levels.
This mechanism, called delayed gastric emptying, is the key reason behind most gastrointestinal side effects. As digestion slows, it can lead to opposite outcomes. Constipation occurs when food moves more slowly, allowing more water to be absorbed. This leads to hard, dry stools. Diarrhea, on the other hand, can happen due to changes in digestion and nutrient absorption. This pulls excess water into the intestines and results in loose stools.
Constipation or Diarrhea: Which Is More Common with Ozempic?
Both constipation and diarrhea can occur with Ozempic, and both are commonly reported, though frequency may vary between individuals. These symptoms are part of the broader gastrointestinal side effects seen with GLP-1 medications.
| Factor | Constipation | Diarrhea |
|---|---|---|
| Common cause | Slowed gut movement | Disrupted digestion and absorption |
| Stool pattern | Hard, infrequent | Loose, frequent |
| When it happens | Early weeks or low fluid intake | After a dose increase or food triggers |
| Duration | Can last several weeks | Usually improves faster |
| Risk factors | Low fiber, dehydration | Fatty foods, large meals |

How to Handle Constipation or Diarrhea with Ozempic?
Digestive side effects like constipation or diarrhea are common with Ozempic because it slows digestion and changes how your gut processes food. Semaglutide slows stomach emptying, which directly affects bowel movements and can lead to these symptoms.
What Can You Do If Ozempic Is Causing Constipation?
Here are some practical steps you can take to relieve constipation:
- Drink enough water daily to help soften stool and prevent dehydration.
- Increase fiber intake gradually, as recommended by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), to support regular bowel movements.
- Stay physically active, as regular movement can help improve digestion and bowel function.
- Try to go to the bathroom at the same time each day to train your body.

- Constipation can last for several weeks during the early phase of treatment.
- It usually improves as your body adjusts to the medication.
What If Constipation Does Not Improve?
If symptoms persist, these options may help:
- Healthcare providers may recommend options like polyethylene glycol (MiraLAX).
- Stool softeners such as docusate can help.
- Fiber supplements may help improve bowel movement regularity.
Always talk to your healthcare provider before using these regularly.

What’s the Best Diet While Taking Ozempic?
Your diet can directly affect how your body responds to Ozempic, especially if you are dealing with constipation or diarrhea. According to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), what you eat and drink plays a key role in managing digestive symptoms like constipation.
What Should You Eat If You Are Constipated on Ozempic?
Focus on high-fiber foods such as:
- Whole grains such as oats and brown rice
- Fruits like apples and prunes
- Vegetables and legumes for added fiber
These foods support digestion and help make stools easier to pass.

- Alcohol and caffeine, which can irritate your digestive system.
Some people may also notice that certain foods trigger symptoms more than others, so it’s important to pay attention to how your body responds.
When Should You See a Doctor for Ozempic Side Effects?
Most digestive side effects, like constipation or diarrhea, are mild and improve over time. However, some symptoms may indicate a more serious problem and should not be ignored. You should seek medical help if you experience:
- Severe or persistent abdominal pain
- Ongoing vomiting or inability to keep fluids down
- Blood in your stool
- Inability to pass stool or gas
- Signs of dehydration, such as dizziness or low urination
The FDA states that severe gastrointestinal reactions and dehydration-related complications can occur in some patients taking semaglutide. If your symptoms feel unusual, severe, or do not improve, it is important to contact your healthcare provider.
How Long Do Ozempic Side Effects Last?
Most people experience gastrointestinal side effects early in treatment, especially after starting Ozempic or increasing the dose.
- Early phase: Symptoms may begin within the first few weeks
- Adjustment phase: Your body gradually adapts over time
- Long-term: Symptoms often improve or become manageable
A pharmacovigilance study published on PubMed Central (PMC) shows that gastrointestinal adverse events with semaglutide are most commonly reported during the early stages of treatment and tend to decrease over time as the body adjusts.
The Bottom Line: Can Ozempic Cause Constipation or Diarrhea?
Ozempic causes constipation or diarrhea because it slows digestion and changes how your body processes food. While these gastrointestinal side effects can feel uncomfortable, they are usually temporary and are likely to improve as your body adjusts to the medication. Knowing the cause and managing symptoms early can help you stay consistent with your treatment.
