Blood in the stool is more of a concern in young children than in
older children and adults. Bleeding in the digestive tract may be present if
there is more than a streak of blood on the surface of the stool or on the
diaper. A visit to a doctor is needed immediately.
Since blood acts as a laxative and an irritant, it will cause your
child to pass any hard, dry stools that are in the digestive tract. Bowel
movements will then become looser and more bloody. Depending upon where the
blood is coming from (usually in or below the stomach) and how quickly it is
moving through the digestive tract, the blood may be bright red, reddish brown,
black, or tarlike (tarry).
A visit to a doctor is needed immediately if your child is passing
stool that looks like red jelly. This type of stool may indicate that a portion
of the intestine has telescoped into another segment of the intestine (intussusception).
If your child has significant bleeding in the digestive tract, you
will notice a moderate to large amount of blood in the child's stool (enough to
leave a pinkish or red stain in the diaper or turn the water in the toilet bowl
red). This can be caused by swelling, irritation, or infection.
