Hello, yes... my story is a bit different but I was able to get my a1c back down... when I was going through cancer treatments I had to be on an insulin pump bc of the high dose IV steroids. I also gained over 60 pounds during that time (and was already overweight.) My a1c spiked to over an 11. After I was finished with treatments, we did a trial of taking me off the pump to see if I could get my a1c under control. We played around with my meds a few different times. It took a good 2 years to get to where I'm at now, a 5.8 and 105 pounds down from my highest weight with about 50 left to lose. I'm currently on jardiance and tresiba.
My endocrinologist also suggested a more plant forward based diet and intermittent fasting. With that, I've noticed quite a difference. My blood sugars are improved even more and I'm needing quite a bit less long acting insulin than before!
Best wishes to you. You got this! 🙂
