Pediatric - Stools, Unusual Color
Stools - unusual color
Back to Index
Does this describe your child's symptoms?
- A stool color other than brown or tan
- Almost always due to food coloring or food additives.
- Stool color relates more to what is eaten than to any disease.
- In children with diarrhea, the GI passage time is very rapid. Stools often come out the same color as the Kool-Aid or Jell-O water that went in.
Clues to Unusual Stool Colors
- Blood from lower GI tract bleeding
- Foods: red Jell-O, red or grape Kool-Aid, red cereals, tomato juice or soup, tomato skin, cranberries, beets, red licorice
- Medicines: red medicines (e.g., Amoxicillin), occasionally other medicines that turn red in the GI tract (e.g., Omnicef)
- Blood from stomach bleeding (stomach acid turns blood to a dark, tar-like color)
- Foods: licorice, Oreo cookies, grape juice
- Medicines: iron, bismuth (e.g., Pepto-Bismol)
- Other: cigarette ashes, charcoal
- Bile: Dark green stools from bile may look black under poor lighting. Smearing a piece of stool on white paper and looking at it under a bright light often confirms that the color is actually dark green.
- Foods: green Jell-O, grape-flavored Pedialyte (turns bright green), spinach or other leafy vegetable. Dark green stools (e.g., spinach) may look black under poor lighting.
- Medicines: iron (e.g., in formula)
- Bile: Most dark green stools are normal and due to bile. Bile-stained loose stools are seen with diarrhea illnesses and normal breastfed stools (especially during the first 2 months of life). While bile is more commonly seen with diarrhea, it can also cause green formed stools.
White Or Light Gray:
- Foods: milk-only diet
- Medicines: aluminum hydroxide (antacids), barium sulfate from barium enema
- Liver disease: Young infants with blocked bile ducts have stools that are light gray or pale yellow.

HOME CARE ADVICE FOR STOOLS - UNUSUAL COLOR
And remember, contact your doctor if your child develops any of the "Call Your Doctor" symptoms.
- Unusual colors of the stool are almost always due to food coloring.
- The only colors that may relate to disease are red, black and white.
- All other colors are not due to a medical problem.
- Green Stools:
- Green color of the stools is almost always normal and due to bile.
- While it is more commonly seen with diarrhea, sometimes it occurs with formed stools.
