Level 2
KEY POINTS:
Constipation is common in people with celiac disease, both before diagnosis and after starting the gluten-free diet. For some people, starting the gluten-free diet resolves the constipation. However, for others, constipation is a new problem that happens after starting the gluten-free diet. 1
- Symptoms can include infrequent bowel movements (often fewer than three bowel movements per week), straining, and hard stools. 2
- Accidental or intentional gluten exposure is one of the main causes of constipation in people with celiac disease.
- The typical gluten-free diet is low in fiber. 3 Fiber, along with adequate fluid, is recommended as a very common way to treat constipation.4
- However, too much fiber can lead to gas and bloating. Therefore, it is important that you add fiber slowly to your diet as well as drink enough fluid to prevent these undesirable side effects. Your intestines needs to adjust to the higher fiber load and this takes time.
- To help treat constipation, be sure you are also drinking adequate water throughout the day.
IDEAS FOR ADDING FIBER TO BREAKFAST:
- Hot cereals made from labeled gluten-free buckwheat, amaranth, quinoa, and specially produced labeled gluten-free whole rolled oats with sliced almonds, ground flax seed, and dried or fresh fruit
- Yogurt (preferably Greek yogurt) with dried, fresh or frozen berries or other cut fruit, ground flax seed or chia seed, homemade gluten-free granola or plain nuts
- Whole egg or egg white frittata made with roasted peppers, spinach, asparagus, tomatoes, and shavings of your favorite cheese with gluten-free high fiber crackers or toast
- Be sure to have something to drink at each meal and in between.

Other causes of constipation can be*:
- Certain medications such as pain medications and supplements
- A sign of another medical condition, such as problems with your thyroid
- Not going to the bathroom when you feel the urge to do so
- Lack of physical exercise 5
- Inadequate fluid intake
- Generalized illness

- Frequent use or misuse of laxatives 6
TAKE HOME MESSAGES:
- The amount of fiber that is needed to correct constipation varies person by person. It Ais best to gradually increase the amount of fiber in your diet so that your intestines can adjust. 1
- Drink enough water as you increase your fiber intake.
- Inform your doctor or dietitian if you are struggling with constipation.
