Celiac Disease Symptoms, Causes, Diagnosis and Other FAQs
When someone who has celiac disease eats gluten, it triggers an immune reaction in the small intestine. Celiac disease symptoms include bloating, nausea, abdominal pain, and diarrhea or constipation, among others. In some cases, though, it doesn’t cause any digestive symptoms at all. Gluten is a protein found in grains such as wheat, rye, spelt, bulgur, and barley.
