When I had my biopsy I had to quit taking it for only the day that I had the surgery to take it out. My mother had major surgery and had to quit taking it for over a month (she's diabetic too, I'm not).
Anyways, I asked my friend who is a pharmacist, she said it they recommend that you quit taking it because of an increased chance of going into lactic acidosis.
I suggest that you talk to your Dr about it. They will know what is best for what you are having done.
Good luck!

For my pituitay surgery, I quit taking met back in October. My doctor just put me back on it. I would ask your doctor/surgeon directly b/c they know what interactions will occur possibly during your surgery, good luck and you'll do just great with your surgery!!!
I just had surgery on the 13th. My dr told me to stop taking the met 10 days before surgery (I actually stopped a lot sooner so I could drink for New Years ) and he told me to start it again about 4-5 days after surgery. I also suggest talking to your surgeon about it.
