Concerning the bowels
Gastrointestinal refers to the stomach and intestines together, or more broadly to the entire digestive tract from mouth to anus: gastrointestinal disorders, gastrointestinal bleeding.
Often abbreviated GI, especially in medical contexts: a GI specialist, upper GI endoscopy.
The adjective appears almost exclusively in clinical or scientific writing.
