Celiac Disease (Non-Tropical Sprue)
What Is It?
Celiac disease (also called non-tropical sprue, celiac sprue, gluten intolerance and gluten-sensitive enteropathy) is an intestinal disorder in which the body cannot tolerate gluten. Gluten is a natural protein in many grains, including wheat, barley, rye and oats.
People with celiac disease have an immune reaction that is triggered by gluten. The immune reaction causes inflammation at the surface of the small intestine where it damages small structures - villi - on the surface of the intestine. It also damages smaller, hair-sized protrusions called microvilli. Healthy villi and microvilli are needed for normal digestion. When they are damaged, the intestine cannot absorb nutrients properly and you can become malnourished.
