The name Melena is of American origin and is primarily used for females. It is a form of the name Elena, which carries the meaning "Form Of Elena." However, it is important to note that "melena" is also a medical term referring to dark black, tarry feces that are typically associated with upper gastrointestinal bleeding. This condition is caused by the alteration of hemoglobin in the blood by digestive enzymes and intestinal bacteria. Common causes of melena include peptic ulcer disease, upper gastrointestinal bleeding, and complications of certain medications or foods. It is considered a medical emergency and requires urgent care to rule out serious underlying causes. The term "melena" has its origins in modern Latin, via the Greek word "melaina," meaning black. It is crucial to distinguish the medical term from the given name when interpreting the meaning of the name Melena.
