Why do
Anal Fissures happen?

Fissures are primarily caused by trauma to the anal lining. However, it is the **spasm of the muscle** that prevents it from healing, turning it into a chronic condition.

The "Vicious Cycle" of Pain

It starts with a Hard Stool causing a tear. The pain causes the anal muscle to go into Spasm (tightness). This tightness cuts off blood flow to the area, preventing healing.

  • 1 Pain triggers Muscle Spasm
  • 2 Spasm reduces Blood Flow
  • 3 Poor Blood Flow = No Healing

Primary Risk Factors

01

Hard Stools (Constipation)

The #1 cause. Passing a large, hard stool stretches the anal canal beyond its limit, causing the delicate lining (mucosa) to tear.

02

Chronic Diarrhea

Frequent bowel movements and the acidic nature of loose stools can erode and inflame the anal lining, making it prone to tearing.

03

Childbirth (Trauma)

Women are prone to fissures after vaginal delivery due to the immense pressure and stretching of the perineum during labor.

04

Tight Anal Sphincter (Hypertonia)

Some people have naturally tight anal muscles. This high pressure reduces blood flow to the area, preventing small cuts from healing.

05

Dietary Habits

A diet low in fiber and water leads to hard stools. Excessive spicy food consumption can also cause burning and inflammation.

Why Fissures Don't Heal

The Role of Spasm

"We treat the muscle tightness, not just the cut. Once the muscle relaxes, the blood flow returns, and the cut heals itself."

Dr. Jaya Maheshwari explains why applying ointments alone isn't enough if the anal muscle remains tight and how we treat the root cause.
