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.
Celiac disease, also known as coeliac disease, is an autoimmune disorder that affects around 1 in 100 Americans. The disease is caused by gluten intolerance. Gliadin, a protein in wheat, causes the afflicted persons immune system to attack its own bowel tissue. This causes villous atrophy, or the erosion of the nutrient absorbing villi that line the small intestine. Other grains, like barley and rye, have similarly shaped proteins which can cause the same reaction in sensitive individuals. Celiac disease can cause irreversible damage. The issue seems to be genetic in cause and can be passed down through generations. Testing for celiac disease is done through blood tests and endoscopy. It is important for the afflicted person to continue eating gluten while they are tested for celiac disease.
