Detailed Answer:
Hello XXXX
Thanks for writing to HCM

There are many causes of green stool.It indicates that food has been moved through the large intestine too quickly,such as due to watery diarrhea due to Clostridium difficile (typically after antibiotic use).As a result,bile doesn't have time to break down completely.
Green colour stool may also be due to intake of green leafy vegetables,green food coloring agents such as in flavored drink mixes,iron supplements etc.

Mostly green colour stool is due to benign reasons but frequent occurrences of green stool need medical attention to ensure that an infection is not present.

Get well soon.

My Mother has C-Diff and can no longer take most antibotic so the question is how do we treat small infections like a sinus infection or a kidney infection. I know the one antibotic she can take is Flagaral but if she takes it to much will it help her when the c-diff acts up again. Also how contagious is it when she isnt sick with it.
