Constipation

Celiac illness can produce diarrhea in some people but constipation in others. Celiac disease causes intestinal villi destruction. These are tiny fingerlike extensions in the small intestine that are in charge of nutrition absorption. The intestinal villi are unable to adequately absorb nutrients when food passes through your digestive tract and frequently absorb excess moisture from the feces instead. Constipation results from hardened feces that are difficult to pass.

Even on a rigorous gluten-free diet, patients with celiac disease may struggle to avoid constipation. This is because a gluten-free diet excludes numerous high-fiber foods, such as grains, which may result in lower fiber intake and frequency of bowel movements. Constipation can also be caused by physical inactivity, dehydration, and a bad diet.
