More to Know

Many things can cause blood in the stool, depending on a person's age. Pinpointing the exact source of the blood is not always easy. Treatment depends on the cause of the bleeding.

Blood in the stool can range in color from bright red to black. It might only be seen in the underwear or on toilet paper when wiping. Sometimes the blood isn't visible at all, but is found when a stool sample is examined in a laboratory.
