Dark green stool? just had a lactulose breath test. does that cause the dark green soft stool?

Stool color is dependent on the effect of gut action by time/germs on the debris passing through. Bile is the main colorant, starting as ultra green and changing thru lighter green/yellows/browns the longer it stays in. Green poop just means it went through faster. It has no other significance.
