Fissure

An anal fissure is a small split or tear in the thin, moist tissue (mucosa) that lines the anus (lower rectum). It causes pain and bleeding during bowel movement.

Although anal fissures are very common in young infants but it can affect people of any age. The rate of anal fissures drops with age. It does not lead to any serious problem and generally heal on their own.

Anal fissures occur due to injury or trauma to the anal canal. Injury can happen because of any of the following reasons:

  • Passing large or hard stools
  • Chronic constipation
  • Straining during bowel movements
  • Chronic diarrhea
  • Inflammation of the anorectal area, caused by Crohn’s disease or another inflammatory bowel disease
  • Childbirth
  • Rectal intercourse
  • Decreased blood flow to the area in older adults
  • Excessive tension in the sphincter muscles that control the anus

Anal fissure can be a painless wound that may bleed from time to time but neither causes any symptoms nor does it heal. Other than this some patient experience severe symptoms like:

  • Severe, sharp and stinging pain during and after bowel movements

  • Small spot of bright red blood toilet paper or a few drops in the toilet bowl after a bowel movement
  • Itching or irritation around the anus

Nonsurgical treatments like:
