Description:Celiac disease is an autoimmune disease, which means your body attacks itself.
In Celiac disease, your body makes antibodies to the villi, or small projections in the small intestine. The small intestine is where most of your nutrients are absorbed. When the antibodies attack these villi, the villi become damaged and your intestinal lining becomes like a tile floor instead of a nice fluffy shag carpet.(1:44)
