Frequently Asked Questions

1. What is an anal fissure?

An anal fissure is a tear in the lining of the anus that can cause extreme pain both during bowel movements and afterwards. Other symptoms include small amounts of bright red blood (on toilet tissue or inside the toilet bowl), anal itching, discomfort while walking or exercising, and increased flatulence.

2. What causes an anal fissure?

In many cases, anal fissures are caused by attempting to pass a hard, dry piece of stool while constipated. Other causes include excessive tension in the anal sphincters (two muscular rings), stress, diarrhea, Crohn’s disease, inflammation of the anorectal canal, and childbirth. Research shows that 11% of women develop fissures while giving birth.

3. Who gets anal fissures?

Men and women of all ages develop anal fissures.

4. What is nitroglycerin?

Nitroglycerin is a drug commonly prescribed for people with heart conditions as it has been shown to relax the blood vessels, making it easier for the heart to pump and blood to circulate. Tablet, capsule or spray formulations are typical for heart patients. In recent years, the drug has been found to have benefit in the treatment of anal fissures when added to a topical ointment in reduced concentrations (0.2% or less).

5. Does an anal fissure increase the risk of colorectal cancer?

No. An anal fissure does not increase your risk of developing colorectal cancer. But since both conditions can produce bleeding as a symptom, it’s important to determine whether cancer may also be present. After treating your anal fissure (thus resolving any bleeding related to the fissure itself), we can screen you for colorectal cancer with a fecal occult blood test (FOBT), which tests for the presence of blood in the stool.

6. How do I know if I have hemorrhoids or an anal fissure?

Good question. Anal pain, itching and bleeding are symptoms of both hemorrhoids and anal fissures. As a result, it’s possible for people to incorrectly self-diagnose themselves. Always consult a physician for a proper diagnosis. Because bleeding is also a symptom of colorectal cancer, it’s important to rule other problems as well.

7. Will my insurance cover treatment?

We accept most major insurance plans, including Medicare. As insurance coverage varies, however, please call the nearest center for assistance with regards to your specific policy.
