Stools - Blood In

Pediatric HouseCalls Online

DEFINITION

  • Blood-colored material mixed in with the stool, on the surface or passed separately
  • Blood in the stools is usually bright red
  • Blood from bleeding in the stomach comes out tar-black

Causes

  • Anal Fissure: If no associated diarrhea, more than 90% of children with blood in the stools have an anal fissure.  Anal fissures usually are caused by passage of a large or hard bowel movement.
  • If associated diarrhea, most of the children have Shigella, Salmonella or Campylobacter infections.
  • Some foods (e.g., tomatoes) and some medicines can also cause red-colored stools that look like blood.

  • NOTE: Try to save a sample of the "blood" for testing if your child needs to be seen

HOME CARE ADVICE FOR ANAL FISSURE (Pending Talking with Your Doctor)

  1. 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 (BM)
    • You may see a shallow tear at 6 or 12 o'clock on the anus
  2. Warm Saline Baths: Give warm saline baths for 20 minutes 2 times per day for 1 day to cleanse the area and to promote healing. Add 2 oz. of table salt or baking soda to a tub of warm water.
  3. Steroids Ointment: If the anus seems irritated, apply 1% hydrocortisone ointment 3 times per day for 1 day to help healing.
  4. High-Fiber Diet:
    • For children more than 1 year old, offer a nonconstipating diet.
    • Increase fruits, vegetables and grains (fiber).
    • Reduce milk products to 3 servings per day.
    • If CONSTIPATION is definitely the cause, see that topic.
  5. Expected Course: Anal fissures usually heal up quickly with home treatment.
  6. Call Your Doctor If:
    • Bleeding increases in amount
    • Small bleeding occurs over 2 times
    • Your child becomes worse

And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
