Q. What does the term 'Melena' signify in the medical field?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Melena is a medical term that refers to the passage of dark, tarry, and foul-smelling stools. These stools are typically black in color and have a sticky or tar-like consistency. Melena is caused by the presence of digested blood in the gastrointestinal tract, usually originating from bleeding in the upper digestive system, such as the esophagus, stomach, or the upper part of the small intestine.
The dark color of melena is due to the digestion and breakdown of hemoglobin from the blood. Melena is often an alarming symptom and suggests the presence of bleeding in the digestive tract, which can be caused by various underlying medical conditions, such as peptic ulcers, gastritis, esophageal varices, or certain gastrointestinal cancers. It is important to seek immediate medical attention if you experience melena, as it may indicate a serious medical issue that requires diagnosis and treatment by a healthcare professional.
