Celiac disease (gluten-sensitive enteropathy), typically known as disorder or celiac, is an immune response to ingestion protein, a protein found in wheat, barley and rye. If you have got disorder, ingestion protein triggers an immune response in your gut.
Over time, this reaction damages your small intestine's lining and prevents absorption of some nutrients (malabsorption).
The enteric injury typically causes diarrhea, fatigue, weight loss, bloating and anemia, and can lead to serious complications.
