I just got the results of my first A1C test since I got my MM CGMS. It wasn’t as good as I’d hoped, but it’s encouraging and I know I can do better. Prior to my pump, my A1C hovered around 7.0 - 7.2. My first pump A1C dropped to 6.2. My first CGM A1C dropped to 6.1. That equates to an average BG of about 117.
Two things make this “improvement” good news. First, I almost eliminated hypos since getting the CGM, so the would tend to push the average higher (meaning I must be spending a lot less time in the hyperglycemic state). Second, I’ve long suspected my glucose meter reads a little high and my target level was set to 100. So given the 20% accuracy of meters, my average falls right within the error bar of my target.
On MDI, my target was usually 80 - 90. But when I went on the pump my CDE set it to 100 (probably as a caution) and I never adjusted it. Today I lowered my pump target BG to 90. If that works, my next A1C should drop about 0.3
What kind of improvements or changes have others on CGM seen?
