Hi ,I am still puzzled about blood sugar levels , so , once you go past 48 mmol/mol you are a diabetic I am told , I hit 66 mmol/mol last year and prior to that held it below 54 mmol/mol , when it went up to 66 my nurse was pushing me for medication to go on , I refused and got it back down to 60 , I was then told I was not controlling it and should go on meds , my latest reading was 54 and I am told that’s ok , can someone tell me what is ok and not ok please .
