Mine is under control (A1C 6.3) but that can change. You don't get to dictate what your pancreas is going to do.
I had an A1C in the 8’s. I went on insulin, cut out the carbs to a controlled level, and within 6 months I was under 5.7. I got off shots and the “Semiglutide” and now use no insulin for 4 years. I was in my mid sixties. You can do it too.
