Etymology
The term 'celiac' originates from the Latin coeliacus, which was borrowed from the Greek koiliakos, meaning 'suffering in the bowels'. This Greek adjective is derived from koilia, meaning 'belly' or 'abdomen'. The literal construction, 'pertaining to the abdomen', accurately describes the condition's primary site of pathology—the small intestine within the abdominal cavity. Over time, its medical usage narrowed specifically to denote the intestinal disorder triggered by gluten, evolving from a general abdominal reference to a precise clinical diagnosis.
