Stools - Blood

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.
• Cow's Milk Colitis. Starts within the first 2 months of life. Causes loose, slimy stools. Can be blood-streaked. Treatment: need to avoid cow's milk formulas.
• 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.

The things listed below can also cause red-colored stools that look like blood:

• Certain foods (such as tomatoes or beets)
