What does gastric mean?
Gastric is an adjective meaning relating to the stomach. It is common in medicine and biology, where it describes the stomach’s structure, secretions, diseases, and the substances associated with digestion, as in gastric acid, gastric juice, gastric ulcers, and gastric bypass. Because the body’s digestive tract has distinct regions, “gastric” can also contrast a stomach-related condition or procedure with one involving the intestines. The word is generally formal and technical, although expressions such as “gastric discomfort” and “gastric upset” are widely understood. Its history is rooted in Greek: gastric ultimately comes from gastēr, meaning “belly” or “stomach,” through Greek and Latin forms. The same root appears in many English medical words, including gastritis, gastroenteritis, and gastroenterology. The term is useful because it identifies the stomach specifically rather than referring broadly to abdominal digestion.
adjectiveRelating to, affecting, or occurring in the stomach. In medical contexts, it may also refer specifically to the stomach as distinct from the intestines.
- Relating to or affecting the stomach.
- Involving the stomach rather than the intestines, especially in anatomical and medical descriptions.

Gastric sounds as if it should mean gassy, but its roots are grimmer: it comes from the Greek word for “belly.”
