Anal Fissure (Tear in the Anal Lining)
An anal fissure is a small tear in the lining of the anal canal, typically causing sharp pain during defecation and small amounts of bright red bleeding. Most acute fissures heal with conservative care; chronic fissures may need additional interventions.
Typical symptoms
- Sharp, tearing pain during and shortly after defecation
- Small amounts of bright red blood on tissue or stool
- Spasm of the anal sphincter
- Itching or discomfort between bowel movements
Acute vs chronic fissure
An acute fissure is recent and superficial. A chronic fissure has been present for several weeks and may show a small skin tag or internal changes. The distinction influences treatment.
Treatment options
Conservative care includes high-fibre diet, adequate fluids, warm sitz baths and topical agents to relax the sphincter. Chronic or unresponsive fissures may need additional medical or surgical options selected case by case.
