You might experience blood in your stool because of a major health concern. Here are five possible causes of blood in your stool.

1. Anal Fissure

An anal fissure is a small cut or tear. This cut is located in the tissue lining of the anus and appears similar to a paper cut or chapped lips.

Benign tumors on the wall of the large intestine are called polyps. Colon cancer and polyps are both potential causes of blood in stool. Over time, this bleeding can cause moderate or severe iron deficiency anemia.
