Anal Fissure

Anal Fissure

An anal fissure is a small tear or crack in the lining of the anus. It is characterized by a burning pain, itchy sensation and rectal bleeding during and after a bowel movement. The condition affects all age groups, but it tends to be found when constipation and diarrhoea are frequent.
Causes and Symptoms of Anal Fissures

Anal fissures commonly occur from straining during bowel movements when passing large or hard stools. Similarly, chronic constipation and diarrhoea may place excessive pressure on the anal canal, causing it to stretch and tear. Other causes of anal fissures include:

  • Childbirth
  • Poor blood flow to the anus
  • Tight or spastic anal sphincter muscles
