Anal Fissure Facts
- An anal fissure is a small tear in the
skin overlying the anus that may occur when a hard stool is passed. Constipation
is the most common cause of anal fissures.
- Pain during the passage of a hard bowel
movement, and sharp pain that continues afterward are the most common symptoms
of an anal fissure. Sitting can be quite painful with an anal fissure.
- A few drops of blood may be seen in the
toilet bowel or when wiping. In an infant, there may be blood in the diaper.
- The sphincter muscles that surround the
anus and help prevent stool leakage may go into spasm and cause longer lasting
pain with an anal fissure.
- Diagnosis is made by history and
inspection of the anus. No other tests are usually needed.
- Treatment basics include drinking more
fluid and eating a high fiber diet. Stool softeners, fiber supplements, and
laxatives may be prescribed.
- Surgery is considered only after diet
and medications have failed.
