I have had a C-diff infection in the past and have recently been put on Biaxcin 500mg/2X day and Flagyl 250mg/3X day. My stool is always gold colored since my first bout w/C-diff. I told the doctor about my C-diff infection and that the doctor said not to go on antibiotics unless I ABSOLUTELY HAVE to and he gave it to me w/the Flagyl anyway. I ve doubled up on my probiotics and am drinking a Kefir smoothie. Occassionally my stool is brown, usually when I eat beef, but most of the time its a gold color. Thoughts? Oh, I m a 59 year old, overweight, female.
