I was told by my Doctor that as my HbA1c was now 4.5% that I could consider myself "cured".
This was nearly 9 years ago. I have progressed to the stage where I am on Metformin and once more my A1c is down to 5%.
So was I cured as a result of my efforts to keep my Bgs down? Of course not. We all know that a cure is a long way off, what your Doc. (and no doubt mine) means it that you have achieved a near normal A1c by the actions you have taken to keep your BGs down.
I think a better word would be "remission" or maybe "controlled", but it all amounts to the same thing,
T2 is progressive, everyone progresses at a different rate, tight control with low BGs is a good place to be, and who knows, you might manage to stay as you are for many years.
But if you don't keep trying then you might not.
Or like me even while still trying you might find your BGs slowly climbing.
Who was it who said "Lifes a *****, and then you die"?
