Anal Fissure (cont.)

Anal Fissure in Infants

Anal fissures routinely occur in infants, and are the most common reason for the presence of blood in the diaper. The most frequent cause is the passage of a hard bowel movement. The infant may grunt or cry when trying to pass the hard stool and drops of blood may be seen on the diaper. Blood is not mixed in with the stool.

It is important not to ignore blood in an infant's bowel movement or diaper because an anal fissure may not be the cause. It is reasonable and appropriate to contact a health care practitioner to arrange a visit.

If constipation is the cause of the anal fissure, adding corn syrup to the formula may be helpful. If the infant is older than 3-4 months, some fruit juice may also help with the bowel movement. The health care practitioner is a good resource for information.

Anal Fissure Symptoms

Severe pain during a bowel movement followed by continuing pain is the classic symptom of an anal fissure. There may be a few drops of bright red blood in the toilet bowel or when wiping but significant bleeding does not occur.

The pain is significant enough to cause the anal sphincter muscles to go into spasm making the next bowel movement or sitting even more painful.
