Green stool — when your feces (poop) looks green — is usually the result of something you ate, such as spinach. Green stool also can occur after you consume certain medications or iron supplements.

Newborns pass a dark green stool called meconium and breast-fed infants often produce yellow-green stools. In older children and adults, green stool is uncommon and rarely cause for concern.

Call your doctor if you or your child experiences green stool for more than a few days. Green stool often occurs with severe diarrhea, so drink plenty of fluids and seek immediate medical attention if you or your child becomes dehydrated.
