What are the symptoms of an Anal fissure?
Anal fissures may cause painful bowel movements and bleeding. There may be blood on the outside of the stool or on the toilet tissue (or baby wipes) following a bowel movement.
Other symptoms may include:
- A crack in the skin that can be seen when the area is stretched slightly (the fissure is almost always in the middle)
What are the causes of an Anal fissure?
Anal fissures are extremely common in young infants but may occur at any age. Studies suggest 80% of infants will have had an anal fissure by the end of the first year. The rate of anal fissures decreases rapidly with age. Fissures are much less common among school-aged children than infants.
Who is at highest risk?
People who are most at risk for developing an anal fissure include:
- Elderly adults
- Women who just gave birth
- People with crohn's disease
- People who have trouble with constipation or chronic diarrhea
The health care provider will perform a rectal exam and look at a sample of the rectal (anal) tissue to determine if you have an anal fissure.
When to seek urgent medical care?
Call your health care provider if symptoms associated with anal fissure are present, or if the fissure does not heal appropriately with treatment.
Most fissures heal on their own and do not require treatment, aside from good diaper hygiene in babies.
However, some fissures may require treatment. The following home care methods usually heal most anal fissures.
- Cleansing more gently
- Diet changes -- eating more bulk, substances that absorb water while in the intestinal tract
- Muscle relaxants applied to the skin
- Numbing cream, if pain interferes with normal bowel movement
- Petroleum jelly applied to the area
- Sitz bath
- Stool softeners
If the anal fissues do not go away with home care methods, treatment may involve:

What to expect (Outlook/Prognosis)?
Anal fissures generally heal quickly without further problems. However, people who develop fissures are more likely to have them in the future.
Occasionally, a fissure becomes chronic and will not heal. Chronic fissures may require minor surgery to relax the sphincter.
Prevention of an Anal fissure
To prevent anal fissures in infants, be sure to change diapers frequently.
To prevent fissures at any age:
- Keep the anal area dry
- Wipe with soft materials or a moistened cloth or cotton pad
- Promptly treat any constipation or diarrhea
- Avoid irritating the rectum
