Melena

Melena refers to black, tarry stools caused by bleeding in the upper gastrointestinal tract, such as the stomach or esophagus. When blood from these areas is digested by the stomach acids, it takes on a dark, sticky appearance. Melena often indicates an ulcer, tear, or other bleeding sources that require medical attention. It’s important to seek prompt evaluation if melena occurs, as ongoing bleeding can be serious. Symptoms may include dizziness or weakness, especially if blood loss is significant. Diagnosis typically involves medical tests to identify the source of bleeding and appropriate treatment.
