Celiac disease is an immune reaction to eating gluten, a protein found in wheat, barley and rye.
If you have celiac disease, eating gluten triggers an immune response in your small intestine. Over time, this reaction damages your small intestine's lining and prevents absorption of some nutrients (malabsorption).
There's no cure for celiac disease — but for most people, following a strict gluten-free diet can help manage symptoms and promote intestinal healing.
