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. An Introduction to Celiac Disease and Its Causes.
What is celiac disease? Celiac disease is an autoimmune disease characterized by an inappropriate immune response to gluten, a protein found in wheat, and to related dietary proteins in rye and barley. This response leads to inflammation of the small intestine and to damage and destruction of the villi that line the intestinal wall.
