Green stools can be because of
or eating certain foods such as green leafy vegetables. Green stool can also indicate a problem with food digestion due to a disease, disorder or other abnormal process.
If you are experiencing diarrhea
and if it is green then it indicates infectious diarrhea needing antibiotics to treat.
We think of a healthy stool as being brown. Bile that is secreted in the first part of the small intestine
is actually green. As stool is digested and passed through the large intestine it is turned into a darker brown color.
If stool is still green by the time it is excreted, it could mean that it went through the large intestine too fast to be changed in color. This is often called "rapid transit" or "decreased colonic transit time", and diarrhea that is green in color could be the result.
If green co lour stool is occasional then no need to panic but if it is associated with diarrhea, then you need to consult physician for treatment.
I hope this information helps you.
