I have had A1C’s in the 7’s for a while now and did start using an insulin pump after originally being diagnosed with a small amount of retinopathy. But my numbers fluctuate a lot. I can go from 30 to 200 or 300 easily in a day. I definitely don’t have within range a majority of the time. I tend to aim higher to avoid lows.
I do take a good amount of Vitamin C. I have problems with inflammation and shoulder pain from frozen shoulder. The Vitamin C helps a lot with that. I have found it helps more than any RX plus no side effects. Some of the things online make me wonder if Vitamin C has helped with my eyes too.
