Gastroenteroptosis is downward displacement of the stomach and a part of the intestines. The intestine is a tube shaped structure that is part of the digestive tract. Gastroenteroptosis comes from the Greek word “gaster” meaning “the belly,” the Greek word “enteron” meaning “intestine,” and the Greek word “ptosis” meaning “a falling.” Put the words together and you have “a falling (of) the belly (and) intestine.”
