What does the term "gastro-" commonly refer to in medical terminology?

The term "gastro-" is derived from the Greek word "gastēr," which means "stomach." In medical terminology, it is commonly used as a prefix to indicate a connection or relation to the stomach. For instance, words like "gastritis" refer to inflammation of the stomach lining, and "gastroenterology" is the branch of medicine that focuses on the digestive system, including the stomach and intestines. This understanding of "gastro-" as relating specifically to the stomach is foundational in the field of healthcare and helps practitioners identify and treat disorders related to this vital organ accurately.
