A member asked:
What is melena, and how do you prevent it?
A doctor has provided 1 answer
A serious finding: Melena is blood that originates in the stomach or first part of your intestine and changes to a black, tar-like substance as it is passed as stool. It means you are bleeding and should seek the care of a doctor immediately. One prevents it by preventing the causes of bleeding in the stomach, namely ulcers or gastritis.
