1. What Is a Melena Stool?
Stools caused by bleeding in the upper GI tract are easily identifiable by their tar-like consistency, putrid odor and inability to flush away. A black stool is referred to as melena and occurs when fresh red blood changes to black during the digestive process.1‘Melaena - Causes - Diagnoses - Management.’ TeachMeSurgery, 3 Apr. 2020, teachmesurgery.com/general/presentations/melena/. Fresh red blood in stools is generally caused by hemorrhoids or issues in the lower digestive tract.
The consistency and color of an individual's stool can reveal a lot about their diet and overall health. Black stools may indicate the presence of blood, but can also be from additives in food, food groups and iron supplements.
