Melena ~ Medical Terminology

Written by Jan Modric in April 1st, 2009   Under: Blood and Immunity, Current Health Articles, Gastro-Intestinal Diseases, Medical Terminology   Tags: , , ,    

Melena (Gk. melas = black) is a medical term for a black tarry stool due to blood in the stool, usually originating from the upper gastrointestinal tract (the stomach, esophagus, mouth, nose).

The term is sometimes (but not medically) used for a black vomit.  

It is important to differ between melena and black bowel movement from reasons, other than bleeding.
