Anal Fissure: Overview

Anal fissure is a tear in the anal membrane, usually causing anal bleeding. The bright color of the blood is helpful to distinguish anal fissure from more dangerous types of internal digestive bleeding (e.g. peptic ulcer, colorectal cancer, etc.). Also common cause of similar bleeding is a burst hemorrhoid. Anal fissures may be caused by defecation of hard stools, or other anal injury. Symptoms include anal pain, anal bleeding (blood on toilet paper, blood in the toilet bowl, etc.), painful defecation, etc. Mild cases may cause anal itching (rather than pain), and this is also common during the healing process.
