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 stool.
- A Strep skin infection around the anus can also cause blood-streaked stools.
- If associated diarrhea, most of the children have Shigella, Salmonella or Campylobacter infections.
- Some foods (e.g., tomatoes or beets) and drinks (e.g., red Kool-Aid) and some medicines (e.g., amoxicillin or omnicef) can also cause red-colored stools that look like blood.

Home Care Advice for Anal Fissure (Pending Talking with Your Doctor)
- 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 stool
- 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 2 times per day for 1 day to cleanse the area and to promote healing. Add 2 ounces (60 ml) of table salt or baking soda to a tub of warm water.
- Steroid Ointment: If the anus seems irritated, apply 1% hydrocortisone ointment (no prescription needed) 3 times per day for 1 day to help healing.
- 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.
- Expected Course: Anal fissures usually heal up quickly with home treatment.
