I came across your question when trying to find the 'green stool' connection myself. I have found that when I drink one large glass of concord grape juice that my stools turn, as you say, "forest green". I was worried until I discovered what triggered it in me. The manufacturer and the internet seem to have no further information about this connection. Maybe more evidence will surface because medical authorities are pushing purple grape juice as good for your heart.
Hope this was what caused your situation also and not a health problem.
Today, I've had several bowel which have been light green, what could be causing this? There had been no pain involved. Thank-you, JMB
I have been having really bad stomach aches for the last month, and just recently when I went to the bathroom it was green. I am wondering what this is, and if it is serious?
My sister started to have green stool two days ago...she is not on any medication. What could be the cause?
I have had green stools for 2 days now. I have been snacking on licorice sticks. I also believe that the licorice is the cause.
I was really concerned because all week I have had very bright green stool. I have just recently gone through a very traumatic experience, so I thought maybe something was wrong with me because of all the stress. Then I finally found this message board and I'm so relieved. It was the Blue corn tortilla chips!
Thanks everyone!
