An anal fissure is a medical disorder that involves a small split or tear in the thin moist tissue (mucosa) lining the lower rectum (anus).
An anal fissure is a small tear of the sphincter around the back passage (anus).
Although the tear of an anal fissure is normally small (less than a centimeter), it can be very painful.
This is because the anal nerves can sense pain easily.
The pain becomes worse when the patient passes stools (feces) and for an hour or so after passing feces.

The blood is normally bright red.
A small amount of blood may be observed on the toilet paper or coating the feces.

A fissure that persists for more than 6 weeks is called a chronic anal fissure (chronic means persistent).
This is rare, but treatment can still cause healing.
The main cause is constipation and the passage of a hard stool.
In adults, fissures may be caused by passing large, hard stools, or having diarrhea for a long time.
Other factors are:
1. Decreased blood flow to the area in older adults
2. Too much tension in the sphincter muscles that control the anus
3. Anal fissures are also common in women after childbirth
4. Anal fissure occurs as part of another condition in persons with Crohn's disease or an anal herpes infection.
It occurs in babies as well as adults
Anal fissures are very common in infants, but they may occur at any age.
The rate of anal fissures drops with age.
Fissures are much less frequent among ...
