Celiac disease is a chronic digestive and immune disorder that damages the small intestine. The immune system overreacts to foods that contain gluten. This is a protein that is found in wheat, barley, and rye. Eating these foods damages bulges (villi) in the small intestine. This makes it hard for the body to get the nutrients that it needs.

The doctor will ask about your symptoms and medical history. A physical exam will be done.
Blood tests will be done to look for antibodies and genes linked to the disease.
Images will be taken of the intestines. This can be done with endoscopy. A tissue sample may be taken at the same time. This can be done with a biopsy.
There is no cure. The goal of treatment is to manage symptoms. This can only be done with a life-long, gluten-free diet. A dietitian can help with meal planning. A person must avoid all foods that contain wheat, rye, and barley. This will mean reading food labels carefully. Special care will also need to be taken when eating out.
Vitamin and mineral supplements may also be given to improve nutrition.
