What Causes Blood In Stool?

Blood in the stool (hematochezia) can be a symptom of bleeding in the gastrointestinal tract. The blood in an individual's stool may appear dark, tarry, and black, or it may be brighter red or maroon. If the origination point of the blood is higher up in the digestive tract, it is typically darker in color. Lower origination point yields a brighter, lighter, and richer color. The bloody stool may be discovered in a fecal test ordered by a physician, when wiping, or may be seen on the outside of the stool. The majority of individuals who experience this symptom will only observe mild rectal bleeding.
