Why was the disease celiac called that name?

Celiac disease derives its name from the Greek Word "koiliakos," which means "abdominal" or "belly." The term was first used in the 1st century AD by the physician Aretaeus of Cappadocia, who described the symptoms of the condition, particularly its gastrointestinal manifestations. The name reflects the disease's primary impact on the digestive system, specifically the small intestine, where gluten intolerance leads to various symptoms and complications.
