I have recently been diagnosed with diabetes and given a script for metformin. I have a series of tests over the last few years showing pre-diabetic results with HbAlc of 6.0-6.4 and then a recent bump to 7.2 mmol/mol. I have purchased a blood glucose machine and started testing and trying to understand the results. For example yesterday, the results were: 8.00am.....8.9 mmol/L Fasting 10.20am...7.2 mmol/L Breakfast 8.30am 2 x shortcut bacon slices, 1 egg on mountain bread (35cal 6.75g carb) 2.15pm.....8.2 mmol/L Lunch 12.30pm chicken tender, 1/2 battered fish and salad 10.35pm...5.8 mmol/L Dinner 7.15pm Chicken and veges 10.40pm...6.3 mmol/L Checked 5 mins later My fasting BGL has varied between 5.8 and 7.6 mmol/L. The 8.9 was a surprise. I did some reading and it could be the reported Dawn effect and a residue of the previous night. This would make sense as the last thing I ate before going to bed the previous was a chip sandwich ... OK yes I succumbed to temptation. My GP who is not available for 2 weeks said I could go on metformin now but if I am getting constantly over 8 fasting then Metformin is a must. I have been resisting going on metformin as I have a started a significant weight loss and exercise program and hoping to get the BGL down. I have lost 8kgs and my exercise and activity levels have increased markedly. I appreciate advice on whether I should consider starting on metformin or delay the start. How easy is it to come off metformin if BGL follows weight down?
