What does "No melena" mean in a report or doctor's letter? In our medical dictionary, you will find a patient-friendly explanation of the meaning of this medical term.
"No melena" means that there is no black, tarry, and foul-smelling stool present. This type of stool is often a sign of bleeding in the upper part of the digestive system, such as the stomach. The black color comes from the blood that has been digested. So, when a doctor says "no melena", it means that there is no evidence of this type of internal bleeding based on the stool examination.
