In medical terminology what is celiac?

Celiac refers to celiac disease, an autoimmune disorder in which the ingestion of gluten—a protein found in wheat, barley, and rye—leads to damage in the small intestine. This condition triggers an immune response that results in inflammation and malabsorption of nutrients. Symptoms can include gastrointestinal issues, fatigue, and skin rashes, among others. The only effective treatment is a strict gluten-free diet.
