Green stool

Definition

Green stool — when your feces look green — is usually the result of something you ate, such as spinach. Certain medications or iron supplements also can cause green stool.

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. It's rarely cause for concern.
