Bleeding from the rectum (bloody stools) refers to the bright red blood from the anus, often mixed with stool and / or blood clots.More common rectal bleeding from the colon, rectum and anus.

blood color for rectal bleeding often depends on the location of bleeding in the gastrointestinal tract.As a general rule, the closer the source of bleeding to the anus, the brighter will be blood.Thus, bleeding from the anus, rectum and sigmoid colon, usually bright red and bleeding from the rectum and transverse (transverse colon and a few meters from the anus) are usually dark red or maroon.

In some cases, bleeding from the anus can be black and malodorous.Black

, smelly and tarry stool is called melena.Melena occurs when blood is in the colon and sufficiently long enough for bacteria to break it down chemicals (hematin) which are black.Thus usually means melena bleeding of upper gastrointestinal tract (e.g., ulcer bleeding from the stomach or the duodenum or small intestine).

Sometimes melena may be the result of bleeding from the right portion of the colon.On the other hand, the blood from the sigmoid colon and rectum are usually not retained long enough for colonic bacteria to feces became black.Rarely, massive bleeding from the right colon from the small intestine, or ulcers of the stomach or duodenum can result in a rapid transport of the blood through the gastrointestinal tract, and as a result - a bright red rectal bleeding.In such situations, the blood is moving so fast that not enough time for the bacteria to turn the blood into the black.

Sometimes, bleeding from the gastrointestinal tract may be too slow to look like rectal bleeding or melena.This occult blood (not visible to the naked eye).Blood in the stool detected only by tests (fecal occult blood testing) under laboratory conditions.
