User: What is the disease called ‘celiac disease’?
Assistant: Celiac disease is an autoimmune disorder. It is triggered by a dietary gluten. Gluten is a protein found in wheat, barley, and rye. Celiac disease is diagnosed when the body’s immune system attacks the small intestine and damages the villi, which are finger-like projections that help the intestines absorb nutrients. Symptoms of celiac disease include abdominal pain, bloating, diarrhea, constipation, weight loss, fatigue, and iron deficiency. The only way to treat celiac disease is to remove gluten from the diet.
