This may be wrong, but a blog I read after diagnosis explained BG vs HbA1c something like1 this. BG is a measure of (increased) glucose in the blood which can cause damage. HbA1c is a measure of the damage that has been caused. Even if this is not entirely true, I think it is a useful way to think about this. By the way, my GP told me October that I am "too well controlled" with an HbA1c of 36. My Metformin dose has been reduced from 1000mg to 500 mg per day. Without dragging the thread back to dietary matters too much, I am following roughly her guidelines on cutting down on carbs and "sweet treats" but I am not LCHF. I do a whole heap of exercise, and I think like Douglas, sometimes I do just need to eat for the energy! I am still not testing BG. I can't imagine I am having hypos but before my meds were reduced, I was getting quite ratty at times!
