Anal Fissure: Unknown Causes Many Patients Ignore

Expert Insight by Dr. Karan R Rawat – Fissure Specialist and Laser Surgeon in Agra

An anal fissure is a small tear or crack in the lining of the anal canal that causes severe pain during and after passing stool. While constipation and hard stools are well-known causes, many patients develop fissures without obvious reasons.

According to Dr. Karan R Rawat, a leading gastroenterologist, proctologist, and fissure specialist in Agra, several lesser-known or hidden factors can lead to fissures even when patients feel their bowel habits are normal.

Understanding these unknown causes of fissure can help prevent repeated episodes and chronic fissure formation.

What Is an Anal Fissure?

An anal fissure is a painful tear in the anal mucosa, often located in the posterior midline of the anal canal.

It causes:

  • Severe burning pain during stool

  • Bleeding while passing stool

  • Spasm of anal muscles

  • Fear of passing stool due to pain

If untreated, fissures may become chronic and difficult to heal.

Unknown or Hidden Causes of Anal Fissure

Many patients develop fissures even without severe constipation. Some hidden causes include:

1. Anal Muscle Spasm (High Anal Pressure)

Some individuals naturally have tight anal sphincter muscles, which create high pressure in the anal canal.

This pressure reduces blood supply to the anal lining, making it prone to tears even with normal stools.

2. Frequent Loose Motions

Surprisingly, chronic diarrhea can also cause fissures.

Repeated irritation and inflammation of the anal lining can lead to painful cracks and tears.

3. Spicy and Irritating Foods

Excessive intake of spicy food, chili, and junk food may irritate the anal mucosa and increase the risk of fissure formation.

4. Dehydration

Insufficient water intake can make stools slightly harder, which may repeatedly injure the anal lining.

5. Prolonged Sitting

People with sedentary lifestyles or desk jobs often develop poor bowel habits and increased pressure around the anal region.

6. Stress and Irregular Bowel Habits

Stress can affect gut motility, leading to irregular bowel movements, which increases the risk of fissure.

7. Childbirth

Women sometimes develop fissures after normal vaginal delivery due to strain on the pelvic floor and anal muscles.

8. Excessive Use of Laxatives

Long-term laxative use may lead to irritation and sensitivity of the anal canal, making it prone to fissures.

9. Anal Infections

Certain infections or inflammatory conditions may weaken the anal mucosa, increasing susceptibility to tears.

Symptoms of Anal Fissure

Typical symptoms include:

  • Sharp pain during stool

  • Pain lasting minutes to hours after bowel movement

  • Fresh red bleeding

  • Burning sensation

  • Small skin tag near the anus (sentinel pile)

Complications of Chronic Fissure

If fissures are not treated early, they can become chronic fissures and may lead to:

  • Persistent severe pain

  • Anal sphincter spasm

  • Sentinel pile formation

  • Difficulty passing stool

  • Reduced quality of life

In chronic cases, surgical treatment may be required.

Treatment of Anal Fissure

Treatment depends on the severity and duration of symptoms.

1. Conservative Treatment

  • High fiber diet

  • Adequate water intake

  • Stool softeners

  • Warm sitz baths

  • Topical medications

2. Laser or Surgical Treatment

For chronic fissures not responding to medicines, procedures like:

  • Laser fissure surgery

  • Lateral internal sphincterotomy

may be required.

These procedures relieve anal muscle spasm and promote healing.
