"Celiac disease is a chronic digestive problem that affects the lining of the small intestine and blocks absorption of nutrients from food. If this disease is not diagnosed and treated, it can lead to malnutrition and other serious problems.Celiac disease is thought to be a hereditary, autoimmune disorder. If you have celiac disease, your body has a reaction to a protein called gluten, which is found in wheat, barley, and rye grains. When you eat gluten, your immune system responds by attacking the part of the small intestine that is responsible for absorbing nutrients. A significant deviation from the normal range may require further evaluation by your physician."
