Hi I wonder if any one has had experience of, or knows why my blood glucose levels have started to go up when fasting. I'm type 2 on metformin 500mg daily I started low carb eating approx 3 weeks ago and have been feeling good and seen some weight loss since starting. The first couple of weeks my blood sugar levels were around the 5 mmmol reading all the time. Although I'm sticking to the low carb and not doing anything different, my blood glucose has started to creep up a little but what puzzles me most is the readings of 7 to 8 I'm getting while fasting? I fasted for approx 14 hrs and checked, my reading was 7.8 yet they are never this high after I have eaten? Any ideas anyone? Is this a known thing or am I just "odd"?
