Any color other than brown is an unusual color for stools (bowel
movements). Stool color relates more to what is eaten than to any
disease. Unusual colors of the stool are almost always due to food
coloring or food additives. In children with diarrhea, food passes
through the body very quickly, and stools often come out the same
color as the Kool-Aid or gelatin water that went in.
What are some common colors and causes?
Red: blood, red gelatin, red Kool-Aid, cranberries, red
cereals, tomato juice, tomato soup, beets, red medicines
Black: blood from the stomach, iron, bismuth (for example,
Pepto-Bismol), licorice, cigarette ashes, charcoal, Oreo
cookies, grape juice
Green: green gelatin, iron, spinach, diarrhea, breast-feeding
(especially during the first 2 months of life)
When should I call my child's healthcare provider?
Call IMMEDIATELY if:
The stools are red or black and tarry without explanation.
Your child starts acting very sick.
Call during office hours if:
Other unusual colors continue for more than 3 days after you
have eliminated any suspected foods. Be prepared to bring in a
stool sample.
You have other questions or concerns.
