Can anyone tell me please if Metformin specifically reduces spikes rather than reducing overall numbers. I am not on medication and usually pre meal figures are 6 and below but 2 hours post meal can go up to 10/12. This happens about four times a week. I would ask to go on Metformin if it helps spikes. Doctor reluctant to prescribe previously because of other medication but would probably do it. I can’t see any point in starting if it doesn’t reduce spikes. My diet is good. I’m not sure what acceptable figures are as when I was in hospital (not diabetes)in February and on steroids I was told to aim for under 12 but looking at websites post meal seems to be under 8.5. I was diagnosed in February in hospital so am still quite confused and would love some advice.
