PRELIMINARY QUESTIONS: Is the blood bright red or dark?
Has your baby eaten anything unusual or started any new medications? Foods such as tomatoes, beets, and artificial flavorings can cause reddish stools. Some antibiotics may also discolor stool.
CAUSES:
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.
STEPPS NEEDED:If there was very little blood and your baby seems otherwise healthy, call the
pediatrician during normal office hours.
If your baby is under 12 weeks old; has black or tarry stools, bloody diarrhea, or blood mixed with mucus that looks like jelly; or if your baby seems sick, upset, or lethargic, call a pediatrician right away or go to the nearest emergency room.
