Gastroenterocolitis is an inflammatory disease that affects both the stomach and intestines. The intestine is a tube shaped structure that is part of the digestive tract. Gastroenterocolitis comes from the Greek word “gaster” meaning “the belly,” the Greek word “enteron” meaning “intestine,” the Greek word “colon” meaning “colon,” and the Greek word “itis” meaning “inflammation.” Put the words together and you have “stomach colon (and) intestine inflammation.”
