Anal Fissure

📖What is Anal Fissure?

An anal fissure is a small tear or split in the thin, moist tissue lining the anus, most commonly caused by the passage of hard or large stools that stretch and injure the delicate anal skin. It typically causes sharp, severe pain during and after bowel movements, often accompanied by a small amount of bright red bleeding. While most anal fissures are acute and heal within a few weeks with simple measures, some become chronic, persisting beyond eight weeks and requiring more targeted treatment. Chronic constipation and prolonged sphincter spasm are key factors that prevent healing.
