As the name suggests, an anal fissure is a condition where the anal canal splits open, forming small ulcers. These splits run parallel to the longitudinal axis of the anal canal and are typically spindle-shaped or oval. They often cause severe perianal pain. The classic clinical signs of an anal fissure include pain, bleeding during bowel movements, and constipation. Thus, anal fissures do bleed, characterized by spotting of blood during defecation or blood on tissue after bowel movements. The blood is usually bright red. The amount of bleeding relates to the depth and size of the fissure but generally does not present as heavy or spurting bleeding like with hemorrhoids, and significant bleeding is rare. The bleeding from an anal fissure can also recur periodically. Therefore, it is important to seek timely medical treatment at a hospital to ensure effective therapy and early recovery.
