Causes of Blood in Stool
- Anal Fissure. If no diarrhea, most of these children have a small tear in the anus. This is called an anal fissure. Anal fissures usually are caused by passage of a large or hard stool. This is the cause in 90% of children with blood in the stools.
- Strep Skin Infection. A Strep skin infection around the anus can also cause blood-streaked stools.
- Bacterial Diarrhea. If also has bloody diarrhea, a gut bacterial infection may be the cause. Examples are Shigella, Salmonella, E.Coli 0157 or Campylobacter.
- Red, but not Blood. The things listed below can also cause red-colored stools that look like blood:
- Certain foods such as tomatoes or beets
- Certain drinks such as red Kool-Aid
- Certain medicines such as amoxicillin or omnicef
- Amount. Blood spreads rapidly and widely in water. Passing a stool with a few blood streaks often turns the toilet water pink. It doesn't mean a large blood loss.
Anal Fissure or Tear
- An anal fissure is the most common cause of blood in the stools.
- It causes blood on the surface of a stool. Blood may also be found on toilet tissue after wiping.
- The blood is always bright red.
- Only a few streaks or flecks are seen.
- You may see a shallow tear at 6 or 12 o'clock on the anus.
- Caused by passing a large or hard stool.
