Signs and symptoms
- Blood that comes from higher up in the digestive tract, such as the esophagus or stomach, may turn stool black, which is called \"melena.\" As the blood passes through the body and interacts with enzymes in the digestive process, the blood changes from red to black. This makes it a bit more difficult to see in or on the stool than if there is red blood. Red blood in or on the stool, call…

When these veins rupture, they may cause bleeding, which can cause blood to appear in the stool or in vomit.

Signs and symptoms
- Mallory-Weiss Tear. This is a tear in the mucous membrane that joins the esophagus and the stomach. If this tear bleeds, it can result in melena. This condition is fairly rare (only occurring in four of 100,000 people) and may be caused by violent vomiting, coughing, or epileptic convulsions.
Definition
Symptoms
- A small amount of blood in the stool is usually not visible and therefore goes unnoticed (occult) until it is detected upon a fecal occult blood test. The color of blood in the stool may vary depending on the site of the hemorrhage and transit time. There are two medical terms that are used to describe the presence of blood in the stool.
Pathophysiology
- Melena typically indicates bleeding in the upper gut esophagus, stomach and first parts of the small intestine. The bleeding is from the walls of the gut and due to the action of air and digestive enzymes, the blood degrades to appear black in color often with a slightly foul odor. Many people may not notice this change in the stool unless there is significant blood loss in the gut.
Clinical significance
- Melena is the term used to describe black tarry feces which is a result of old and degraded blood in the stool. It usually indicates an upper gastrointestinal bleed originating within the esophagus, stomach or duodenum of the small intestine.
Causes
- As little as 50 ml of blood in the upper gut can result in melena although it usually requires 100 to 200ml before it becomes clearly evident. While it is reported that melena results in foul-smelling stool, this is sometimes difficult to differentiate from the normal odor. The smell of old blood emanating from the stool may accompany the black tarry appearance of the feces.
