  • Constipation or difficulty with having a bowel movement is common in people with celiac disease, both before diagnosis and after starting the gluten-free diet.
  • Symptoms of constipation can include bowel movements that do not occur very often (fewer than three bowel movements per week), straining, and hard stools. 1
  • Eating gluten by mistake or on purpose is one of the main causes of constipation in people with celiac disease.
  • Slowly adding fiber, along with plenty of fluid (such as water), is the first treatment for constipation.
  • The average gluten-free diet is low in fiber.
  • You can add fiber to your diet with more fruits and vegetables, whole gluten-free grains, dried/cooked beans and legumes, and plain nuts and seeds. Be sure to also drink plenty of water.


  • If you are constipated, look carefully at your diet and lifestyle for possible hidden gluten.
  • Ask yourself: are there some easy ways you can add more fiber to your meals?
  • Talk to your doctor or dietitian if you are having constipation.
