Anal fissure: definition, symptoms, treatments

Anal fissure is a tear in the skin covering the anus. If this condition is common and beguiling, it is advisable to be well informed to better live with it.

What is anal fissure?

Anal fissure


The anal fissure is a painful wound that appears in the form of a racket. In most cases, this fissure is due to a tear in the skin at the level of the anus. This tear is most often found on the back side of the anus. It does not exceed 2 cm from top to bottom.

When the anal fissure is recent, the wound is superficial and pinkish. However, when the fissure has been there for a long time (and becomes, in this case, chronic), the wound is no longer superficial, but deepening. It can even accompany a thickening of the skin.

This infection is very common and benign. However, people who suffer from it will be particularly bothered by the pain it causes. A pathology of adults, it is most visible in young adults and about 15% of women who have just given birth.

Causes of anal fissure

In most cases, the appearance of an anal fissure is linked to a combination of three distinct factors

Trauma to the anus

Trauma to the anus as a result of constipation or the sudden evacuation of a liquid stool is the primary factor in anal fissure.

Poor vascularization of the anal area

The blood supply is not very important at the back of the anus, hence the poor vascularization of the anal area (where 90% of fissures appear).

Sphincter contraction

The significant and permanent contraction that you impose on your anal sphincter can worsen the poor circulation of blood, which is a key factor in the appearance of anal fissure.

Common symptoms

The symptoms of anal fissure are easy to detect: pain, constipation and even bleeding.

Differentiating between anal fissure and hemorrhoids

The symptoms of anal fissure and hemorrhoids are quite similar. That’s why they are often confused by sufferers. Here are some points that will allow you to make the difference between these two pathologies:

  • Hemorrhoids are less painful than anal fissure.
  • Hemorrhoids cause a lot of bleeding.
  • Hemorrhoids cause a small ball to appear in the anus.
