Blood in the stool can appear as black stool, dark red stool, bright red stool or normal color stool (invisible to the naked eye). The symptom indicates a bleeding somewhere along the digestive tract, including the esophagus, stomach, small intestine, colon, rectum and anus. Bleeding may occur in one or more of these areas, for example from a stomach ulcer or from diffuse damages of an inflamed colon. Doctors rely on endoscopic or other diagnostic tests to locate the source of bleeding, they also need to know the specific symptoms and signs to help determinate the underlying causes.

	Blood mixed with the stool may suggest the bleeding is higher up in the colon; the color of blood tends to be dark red or maroon colored.
	The darker the blood, the higher the site of bleeding in the digestive tract.
	Persistent bloody stool that is accompanied with alternate constipation and diarrhea, and unexplained weight loss may suggest a rectal tumor.
	Black, smelly and tarry stool is likely from a source in the upper gastrointestinal tract, such as ulcers in the stomach or the duodenum, or from the small intestine.
	Bloody diarrhea that also contains mucus or pus, and is accompanied with frequent urge to have bowel movement, abdominal pain and fever are likely to have colitis.
	Invisible blood in the stool may be the first sign of colon cancer or polyps, particularly in those 45 years old. Screening tests should be started if you have a family history of colon cancer or polyps.
	A chronic bleeding can lead to anemia, which makes individuals gradually develop fatigue, weakness, dizziness, pallor and shortness of breath.
	Iron supplements, black licorice, lead, blackberries, beets or other color foods can make the stool appear darker than normal.

Generally, blood in the stool can be the result of a wide range of conditions, and the presentations vary according to the cause, location, duration and severity of the bleeding. Sometimes, a brisk bleeding in the upper digestive tract can pass gross blood from the rectum, while an occult or hidden bleeding may only be detectable by a fecal occult blood test. A doctor is the most qualified person to determine whether your bleeding condition is due to hemorrhoids, inflammatory bowel disease, rectal abscess, peptic ulcer, intestinal polyps, cancer or anal fissures. You should report to your family doctor as soon as possible if you notice blood in your stool, or any major change in the color, consistency or frequency of your bowel movements. The sooner you get a proper diagnosis, the easier it will be to treat.
