Blood in the stool is a cause for concern, but not all bloody stools are categorized as melenic. Hematochezia frequently produces blood in stools, however, the color of the blood is different.
Hematochezia results in fresh blood in the stool, which normally comes from the colon or anus.5Wilson, I. Dodd. ‘Hematemesis, Melena, and Hematochezia.’ Clinical Methods: The History, Physical, and Laboratory Examinations. 3rd Edition., U.S. National Library of Medicine, 1 Jan. 1990, www.ncbi.nlm.nih.gov/books/NBK411/. The difference between bloody stools and melenic stools lies in the consistency and color. Consuming blueberries, licorice or iron supplements can also cause dark stools.
