What are the causes of Black Tarry stools?
Black Tarry stools, technically known as Melena , is the condition in which the bowels of the intestines have a deeper color and more sticky texture than normal bowel movements. The brown color of healthy bowel movements is caused by bile, green yellow fabric made in the liver that travels to the intestines during the digestion process and changes solid waste brown. If bleeding occurs in the intestines, it can react with it and produce black color with sticky texture. Intestinal bleeding, which leads to abnormally dark stool, can be caused by a series of conditions that affect the area of the digestive tract.
Gastrointestinal (GI) tract consists of two parts: upper GI tract and lower GI tract. The upper GI tract consists of a stomach, esophagus and upper part of the small intestine, while the lower tract GI includes the lower part of the intestines, rectum and rectum. When any bleeding in the upper GI tract occurs, the digestive chemical body and blackened are mixed. Bleeding the lower GI tract generally leads to the red stool because the KREV is not exposed to digestive juices.
One of the most common causes of bleeding the upper GI tract, which can lead to black tar stools, is a stomach ulcer, a condition in which ulcers or tears are created in the tissue lining of the stomach or tears due to bacteria, weakened immune systems or non -steroidal anti -inflammatory drugs. Sometimes ulcers may start to bleed slightly if ulcers spread to the blood vessels of the stomach. Although bleeding is usually not difficult enough to be immediate danger, it can cause serious pain in the region, especially after eating. It is often treated with drugs that reduce the amount of acids in digestive juices to prevent future damage to the stomach lining.
Black Tarry stools can also be caused by conditions that affect the insid blood vessel upper tract GI. If a person is born with vascular malformation, his blood vessels may not be created correctly and cannot properlycheck the blood flow. Vascular malformation can cause one more likely to have light in the upper GI tract. Common abnormalities of blood vessels may include too widespread blood vessels that give too much blood at once, or tightened blood vessels that prevent blood from traveling quickly enough.
In less common cases, black tar stools may actually be the result of unrelated blood. Eating meals with dark colors such as blueberries and black licorice can cause bowel movements to have a black look. Supplements or medicines that contain metal elements such as bismut or iron can also lead to dark stools.
