Piles And Fistula

Anal fissures are tears, or cracks, in your anus. Fissures are sometimes confused with hemorrhoids. These are inflamed blood vessels in, or just outside, the anus. Both fissures and hemorrhoids often result from passing hard stool.


Fissures result from the stretching of your anal mucosa beyond its normal capacity. This often happens when stools are hard due to constipation. Once the tear happens, it leads to repeated injury. The exposed internal sphincter muscle beneath the tear goes into spasm. This causes severe pain. The spasm also pulls the edges of the fissure apart, making it difficult for your wound to heal. The spasm then leads to further tearing of the mucosa when you have bowel movements. This cycle leads to the development of a chronic anal fissure in approximately 40% of patients.


You may have these symptoms with an anal fissure:

Pain during and after a bowel movement
Visible tear or cut in the area
Bright red bleeding during or after a bowel movement

Risk factors

Certain factors raise the risk for anal fissures, including:

Constipation with straining to pass hard stool
Eating a low-fiber diet
Intense diarrhea
Recent weight loss surgery, because it leads to frequent diarrhea
Vaginal childbirth
Minor trauma, especially trauma caused by high-level mountain biking
Any inflammatory condition of the anal area.
Anal fissures may also result from inflammatory bowel disease, surgery, or other medical treatments that affect bowel movements or the anus.


Your healthcare provider will make a diagnosis based on:

Your personal health history

Your description of symptoms

Rectal exam

Because other conditions can cause symptoms similar to an anal fissure, your healthcare provider might also order tests to find out whether there is blood in your stool.


An acute anal fissure typically heals within 6 weeks with conservative treatment. Some disappear when constipation is treated. Anal fissures that last for 6 weeks or more are called chronic anal fissures. These fail conservative treatment and need a more aggressive, surgical approach.

Other treatments include:

Changing your diet to increase fiber and water, steps that will help regulate your bowel movements and reduce both diarrhea and constipation

Taking warm baths for up to 20 minutes a day

Taking stool softeners, such as fiber supplements, as needed

Using topical medicines, such as nitrates or calcium blockers

Having surgery, such as a lateral internal sphincterectomy. During the surgery, the pressure inside the anus is released. This allows more blood to flow through the area to heal and protect tissues.


Complications seen with anal fissures include:

Pain and discomfort

Reduced quality of life

Difficulty with bowel movements. Many people even avoid going to the bathroom because of the pain and discomfort it causes

Possible recurrence even after treatment


Uncontrolled bowel movements and gas

Living with anal fissures

If you have an anal fissure, take these precautions to avoid making it worse and avoid recurrences:

Take all medicines as prescribed.

Get the recommended amount of fiber in your diet. Avoid constipation or large or hard bowel movements.

Drink enough water to stay well hydrated.

Maintain a routine bowel habit. Ask your healthcare provider about what this should be for you.

Avoid spicy foods while you have an anal fissure, because they may make symptoms worse.
