Home Care (Read "Call Your Doctor…" first):

Definition

An anal fissure is the #1 cause of blood in stools:

  • The blood is bright red, but only a few streaks or flecks are present
  • All the blood is on the surface of the stool or on the toilet tissue after wiping
  • Usually follows passage of a large or hard bowel movement
  • You may see a shallow tear at 6 or 12 o'clock on the anus

Warm Saline Baths

Give warm saline baths for 20 minutes 3 times per day to cleanse the area and to promote healing. Add 2 oz. of table salt or baking soda to a tub of warm water.

Ointments

If the anus seems irritated, apply 1% hydrocortisone ointment 3 times per day to help healing.

High-Fiber Diet

For children > 1 year old, offer a nonconstipating diet. Increase fruits, vegetables and grains (fiber). Reduce milk products to 3 servings per day.

Expected Course

Anal fissures usually heal up quickly with home treatment.

Call Your Doctor If:

  • Bleeding increases in amount
  • The bleeding recurs > 2 times after treatment begins
  • Your child becomes worse or develops any of the "Call Your Doctor…" symptoms
