What term refers to something pertaining to the stomach?

The term that specifically refers to something related to the stomach is "gastric." This term comes from the Greek word "gaster," which means stomach. It is widely used in medical contexts to describe conditions, diseases, or anatomical considerations that involve the stomach. For instance, phrases like gastric acid, gastric bypass surgery, and gastric ulcers all indicate a direct connection to the stomach itself.

The other terms have different meanings; "hepatic" pertains to the liver, "intestinal" refers to the intestines, and "abdominal" relates to the abdomen, which encompasses a larger area that includes not just the stomach but also other organs. Therefore, "gastric" is the correct term to use when specifically discussing matters of the stomach.
