Melena: Causes, Symptoms, and Risk Factors
Melena is a medical term used to describe the passage of dark, tarry stools, which are typically indicative of bleeding in the upper gastrointestinal (GI) tract. This condition can be alarming and may require immediate medical attention. In this article, we will explore the causes, symptoms, and risk factors associated with melena.
- Peptic Ulcer Disease: One of the most common causes of melena is peptic ulcer disease. This condition occurs when there is a break or erosion in the lining of the stomach or the upper part of the small intestine. The ulcer can eventually lead to bleeding, resulting in the characteristic dark stools.
- Gastritis: Gastritis, which is the inflammation of the stomach lining, can also lead to melena. This condition can be caused by various factors, such as excessive alcohol consumption, prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs), or infection with the bacteria Helicobacter pylori.
- Esophageal Varices: Melena can occur if there are enlarged veins in the lower part of the esophagus, known as esophageal varices. These varices are commonly associated with liver disease, such as cirrhosis. When these veins rupture, it can result in severe bleeding and the presence of dark stools.
- Mallory-Weiss Tear: A Mallory-Weiss tear refers to a tear in the lining of the esophagus or stomach, often caused by severe vomiting or retching. This tear can lead to bleeding and subsequently the appearance of melena.
Now that we have discussed some of the causes, let's take a look at the symptoms associated with melena:
- Dark, tarry stools
- Blood in vomit (hematemesis)
- Weakness or fatigue
- Abdominal pain or discomfort
It's important to note that melena is a serious condition that requires prompt medical evaluation. If you experience any of the symptoms mentioned above, it is crucial to seek immediate medical attention to determine the underlying cause and receive appropriate treatment.
While melena itself is not a disease, certain risk factors may increase the likelihood of developing this condition. These risk factors include:
- Advanced age
- Regular use of NSAIDs
- History of peptic ulcer disease
- Chronic alcohol abuse
- Liver disease
