Anal fissure
An anal fissure is a small tear in the lining of the anus, typically causing sharp pain on defecation and small amounts of bright red blood on the paper.
Anal Fissures - Symptoms and Treatment
An anal fissure is a painful condition where a tear occurs in the skin around the opening of the rectum. The causes of anal fissures are still unknown, but there are good treatment options available to relieve your pain.
Symptoms of anal fissure
Some common symptoms of an anal fissure include:
- Blood in stool
- Pain during defecation and for hours afterward
- Constipation
Symptoms of an anal fissure can resemble those of other bowel diseases. Therefore, Kirurgen.dk ensures that you are properly examined before treatment. If there are signs that the symptoms do not originate from an anal fissure, it may be a good idea to undergo a bowel examination.

Treatment of anal fissure
Treatment typically involves regulating bowel movements to allow the anal fissure to heal. This can be achieved with various types of medication, such as muscle-relaxing ointment, laxatives, and pain-relieving medication. In some cases, a surgical procedure may be necessary to resolve an anal fissure.

Frequently asked questions
What is an anal fissure?+
An anal fissure is a small tear in the lining at the anal opening. It typically causes sharp pain with bowel movements and a little bright blood on the paper.
Why does an anal fissure occur?+
Most often it is caused by hard stools or constipation that overstretch the mucosa. Diarrhoea, childbirth and chronic spasm of the sphincter muscle can also trigger a fissure.
Can an anal fissure heal on its own?+
Acute fissures often heal spontaneously within a few weeks with softer stools, a fibre-rich diet and ample fluids. Chronic fissures usually require medical or surgical treatment.
What treatments are offered for a chronic anal fissure?+
First-line treatment is a cream that relaxes the sphincter (e.g. nitroglycerin or diltiazem). If this fails, botulinum-toxin injection or a small operation (lateral sphincterotomy) may be needed.
Is treatment of an anal fissure painful?+
Cream treatment is painless. Surgery is done under anaesthesia and causes only mild soreness for a few days. Pain from the fissure itself usually subsides quickly.
