I have recently had a lot of trouble with a kidney stone... blockage of the ureter has caused distress to my kidneys (evidenced by a high blood creatinine level), and I've had a ureteric stent fitted to bypass the stone as a stop-gap measure until the stone can be surgically removed. When I was in hospital having this treatment I was taken off Metformin and Gliclazide and put on sliding scale insulin, one reason being that it was not felt my damaged kidney could cope with the levels of metformin I was on (1000mg twice a day). I am now home and awaiting an operation to remove the stent and the stone, but I've been put back on only half my dose of metformin plus the Gliclazide, and as a consequence my BG readings are generally between 8 and 12, higher than I'd like. Can anyone tell me the relative risks to my kidney of having too much metformin to cope with, and having too much blood glucose?
