causes of bright blood in stool
Bright red blood in stool is also often caused by anal fissures, which is a small tear or split in the anal mucosa. These fissures can cause pain during bowel movements as well as bleeding. Bright red blood may appear on the stool itself or on the toilet paper after a bowel movement. Anal fissures are extremely common in infants due to their very sensitive tissue and then it becomes less frequent with age.
