WebNov 30, 2022 · Melena refers to black tarry stools, which usually occurs as a result of upper gastrointestinal bleeding. It has a characteristic tarry colour and offensive smell, and is often difficult to flush away. The change to the stool consistency occurs due to the alteration and degradation of blood by intestinal enzymes, resulting in melena.
