What does is mean when you have green stool
I copyied this off the internet...
If you have the occasional green stool—don't panic! Most likely it is normal, and there is a perfectly reasonable explanation. Think about the foods you ate, any vitamins or supplements you took—even if they're not green in color.
There can be many reasons why stool appears to be green. The first and most obvious reason is eating green foods. Green, leafy vegetables contain chlorophyll which could be coloring the stool green. Foods with dark purple coloring like Kool-Aid, popsicles, and gelatin (Jell-O) can also result in rainbow-colored stools. Iron supplements or even foods that are rich in iron can also give stool a green tinge.
Stool can also appear green for physical reasons, and not just from what you've been eating.
If you are a frog...it means you are healthy. For a human, it means you should have a doctor check you up...the green colour may be indicative of a bile-related problem.
Best to consult a medical professional..just to be safe.
My kids have that occasionally, I thought it was from too many fruit snacks!
