An easy-to-understand overview of the symptoms, treatments, and medical options for a tear in the anal canal.

Key points

  • An anal fissure is a tear in the anal canal.
  • These tears may lead to chronic constipation.
  • Anal fissures are the most common cause of bloody stools in babies.
  • Constipation can be treated with stool softeners and by getting more fibre in the diet.
  • Until your child's fissure has completely healed, apply petroleum jelly or zinc oxide cream to your child's anus to make passing stool less painful.​​
