Celiac disease is believed to be an autoimmune disorder. While genetics appear to play a role in causing it, some people at risk for celiac disease will not develop it until something triggers their immune system, such as a viral infection or severe emotional stress.

Genetic etiology of the disease[edit] Celiac disease is an inherited condition where gluten proteins found in grains trigger an immune system attack on the lining of the small intestine. While celiac disease can be life threatening, many times it is not. It is a life altering disorder with symptoms such as diarrhea, fatigue, nausea and weight loss.
