Relating to the abdomen or belly; also referring to celiac disease, an autoimmune condition triggered by gluten.
From Greek koilios (of the belly) + -ac (relating to). The British spelling uses 'coeliac' while American English typically uses 'celiac,' both from ancient anatomical terminology.
Your 'coeliac' artery brings blood to your gut, but now millions of people know this word because of celiac disease—a condition where eating wheat, barley, or rye damages the small intestine.
