Coeliac (noun) refers to a person who has coeliac disease, a chronic autoimmune condition where the immune system reacts to gluten, damaging the small intestine. It is predominantly used in medical and patient contexts and is equivalent to gluten-sensitive enteropathy. The term is used chiefly in UK/European medical discourse and in medical literature; Australians sometimes prefer celiac in informal use, though coeliac is standard in many regions.
