Celiac Disease

(Celiac Sprue; Nontropical Sprue; Gluten-Sensitive Enteropathy)

Definition

Celiac disease is an autoimmune disease of the digestive tract. In celiac disease, eating food with gluten damages little bulges in the small intestine. These bulges, called villi, absorb nutrients from foods. The condition affects the absorption of all nutrients. People with untreated celiac disease often become malnourished.

Causes

Doctors do not fully understand what causes celiac disease. Eating gluten seems to be involved. There is most likely a genetic factor. Those with specific genes develop the disease after exposure to gluten. There is some evidence that earlier exposure in infancy can cause a more severe disease than later exposure.
