A member asked:

What?couls cause?my stool to be dark green?

A doctor has provided 1 answer

Stool color: Decomposed bile, which is originally green, gives stool its yellow color. Having said that, green stool may mean that bile has rushed through the intestines without being acted on by bacteria like during diarrhea. Another cause of green color is unabsorbed iron in the diet.
