stool AndyMC You have probably eaten something with a lot of chlorophyll or other green pigment. If this only happened once, that is the logical explanation. If your stool remains bright green constantly, and you are not on an exclusive seaweed and spinach diet, I suggest you have a gastroenterologist take a look at it. This is actually important if you are having other symptoms, such as intestinal cramping, diarrhea, nausea, vomiting, or weight loss. I would review carefully what you are eating and drinking. Are you taking any new vitamins or herbs? Any new medications? You may be able to provide clues by reviewing what is going into your body. Good luck. 040307 ... white_wave the girl in my lab at work analyzes stool all day. she has this gadget that spins the stool. there is a sticker on it that says "I fling poo". 040307 ... ergo as we sit intent let no stool come between us 161129 what's it to you? who go blather from
