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

Newborns pass a dark green stool called meconium, and breastfed infants often produce yellow-green stools. In older children and adults, green stool is not common. However, it's rarely cause for concern.
