Any one who's gone off Metformin . . . how long does it stay in your system?? I know it takes 2 - 3 weeks to kick in when you start taking it, how long does it take to completely leave your system when you stop? Due to my increase in exercise and lowering of carbs I have stopped taking it (2nd day) but feel that kind of weird lowish, head spinny thing.
Remember that Metformin works over an extended period of time- about 12 hours. The risk of hypoglycemia when continuing Metformin while NPO is much greater than the risk of hyperglycemia from the stress response. The medication can be resumed after the surgery, when the patient is eating a normal diet again.
