Celiac disease is an abnormal immune system reaction to gluten, a protein found in grains like wheat and rye. It damages the small intestine so that it can't do a good job of absorbing nutrients from your food.
If you have celiac disease, you need to avoid foods that contain gluten.
Celiac disease is also known as celiac sprue, gluten-sensitive enteropathy, and nontropical sprue.
