I use dexcom g6 and medtronics pump, brought down my a1c with low carb diet, not keto, I was following a diet from a Dr Bernstein. I modified it for myself but stick to 6-12-12 no more than 30 grams of carbs daily. I'm down to 5.9.

I got the Omnipod 5 and the Dexcom g6 they have got my A1c to 6.2

I use a Tandem X2 insulin pump with Control IQ automated insulin delivery system to keep my A1C in the 5 range. Latest endo visit was 5.4.

Stay on top of checking your sugar an making sure your giving yourself insulin for what you eat my A1C was 13 last year an now I’m at 7.4

Is your A1C even accurate? Probably about 30 years ago, my Endo suspected that my A1C was not an accurate indicator of my blood sugar levels. He ordered a Fructosamine lab test. My last 2 Endos have routinely ordered it as well. But now with all the data and reports we have access to, I now know for a fact that my A1C is incorrect. The Fructosamine level corresponds to my TIR data. You may want to talk to your Endo about ordering both tests at least once to see if they’re comparable. If they are, then you know you need to make changes in your Diabetes protocol.
