The condition of green stools has many different causes, sometimes just from eating habits, but it does not rule out signs of serious diseases of the digestive tract. So what are the common causes of green stools?

I have been having diarrhea and irregular and green stools for 5 months now. I went to the hospital to check: Endoscopy, tests, the doctor said it was okay and gave me some medicine, but almost a month after I went to the doctor, I still had diarrhea. So the doctor asked me what disease is diarrhea with green stools for 5 months?

Hi Doctor, I have chest pain and stomach cramps. I have green poop. So the doctor let me ask if the chest pain, abdominal pain accompanied by green stools is okay? Thank you.
