Why Is My Poop Olive Green?

Greenish stool could indicate that you have a bacterial infection (salmonella or E. coli, for example), viral infection (norovirus) or a parasite (Giardia) causing a rapid transit “gush” of unabsorbed bile.

Why does my poop look olive green?

Green stool is usually the result of eating a large quantity of leafy, green vegetables. Specifically, the chlorophyll in the plants produces the green color. Alternatively, children might have green stool after eating artificially colored frosting at a birthday party.

When should I be concerned about green poop?

Although green stools aren't usually a cause for concern or a sign of cancer, you shouldn't ignore green poop that's accompanied by other symptoms. If you have other symptoms, such as recurring diarrhea or vomiting that doesn't improve, this can indicate another serious medical condition. Talk to your doctor ASAP.
