What is celiac disease?
Celiac disease is a disease that damages the small intestine, the digestive systemand prevents the absorption of nutrients from food. People who have celiac diseasecan not tolerate gluten, a protein found in wheat, rye and barley. Gluten is foundmainly in foods but can also be found in everyday products such as medicines, vitamins, and lip balm.

When people with celiac disease eat foods or products containing gluten, their immune system responds by damaging or destroying villi-the tiny, fingerlikeprotrusions lining the small intestine. Villi normally be taken by nutrients from foodthrough the walls of the small intestine into the bloodstream. Without healthy villi, a person becomes malnourished, no matter how much food to eat.
Absorbing villi in the mucosa of the small intestine nutrients.
Celiac disease is both a disease of malabsorption-meaning nutrients are not absorbed properly, and an abnormal immune reaction to gluten. Celiac disease isalso known as celiac sprue, nontropical sprue, and gluten-sensitive enteropathy.Celiac disease is genetic, meaning it runs in families. Sometimes the disease is triggered-or becomes active after the first surgery, pregnancy, childbirth, viralinfection or severe emotional stress.
