Remission really is such a novel idea that there are differing opinions about it, and a lot is down to the individual surgery or even people within them.
The good thing, though, is that 44 is definitely not in the diabetic range, and is very close to the top end of normal.
I know how powerful numbers can be - I get very twitchy if someone seems to be wanting to weigh or measure me after decades of it being the start of verbal abuse, and when my Hba1c went down to 47 at the first retest and 41 at 6 months the significance given to those numbers was powerful affirmation of my getting it right. After half a century of being told I was wrong - I hope you forgive my irrepressible glee.
Those results were like having engine failure and finding it possible to glide in for a perfect landing.
I can only advise assessment of carb intake, testing after meals, even a bit more exercise, as I am entirely unaware of just what path you have travelled to get where you are now. You were, obviously, fully diabetic, but now are no longer. Don't blow it now you are so near to normal numbers.
