Green, brown and even yellow are okay for baby’s poops, but grey – even if the stools are only part grey and part green, means big trouble.
Even if poops appear as a mix of colors, if grey is one of those colors, such as “brownish-grey,” this means a visit to the doctor.
Make sure you are viewing your baby’s stools in good light to be sure about the color.
If you are absolutely positive that your baby’s poo can most accurately be described as greyish or even a “greenish grey,” waste no time taking the baby to a pediatrician to find out what the cause is.
“Pale, clay-colored, grey or grey green stools in an infant mean LIVER problem!” warns Jacqueline Winkelmann, MD, who’s been a hospital-based pediatrician at CHOC Children’s Hospital in Orange County, CA, and most recently Chief of Staff at CHOC Children’s at Mission Hospital.
“An infant with grey green stools might be a cause for concern,” continues Dr. Winkelmann.
“Babies born with biliary atresia, a condition in which there is a blockage or absence of biliary ducts, the bile cannot reach the small intestine during digestion. Bile is what gives stool its brown color.”
There are other conditions that can cause a baby’s poops to come out grey or predominantly grey mixed with brown, tan or green.
Dr. Winkelmann says that liver disease such as hepatitis can be a cause. So can gallstones and liver tumors.
“Medications used for diarrhea (like Pepto-Bismol) can give the stool a pale, greyish color,” says Dr. Winkelmann.
Another possible cause is “If a baby has had an X-ray procedure using barium (liquid baby’s drink before having an X-ray of the upper digestive tract). After the procedure, the baby will have several poops that are grey colored.”
If your baby has not undergone this procedure, it can’t be said enough: Get a doctor’s appointment as fast as possible.
A poop color that you can honestly describe with the word “grey” somewhere in there is simply NOT normal and requires a medical evaluation.
Does grey in a baby’s poop always mean
something is wrong?
No, it is not a guarantee. It could be caused by what the baby is ingesting. Discuss this with your pediatrician.
But as long as serious diseases can also cause grey to appear in the poo, this fact qualifies your baby for a visit to the pediatrician to at least hopefully rule out anything serious. Why take a chance?
