Looking over the posts here, it seems that many people have higher HBA1C results than they are expecting from their Dexcom Clarity numbers.
I’m actually in the opposite boat. My Dexcom Clarity numbers have historically been pretty high (average of 160 to 200) but my HBA1C tends to always run at 7.0 or lower. My most recent A1C was 6.1 even though my Dexcom Clarity average for the prior 3 months was 171.
The variable of “how long do red blood cells last in blood or glucose bond to hemoglobin” (or something like that) perhaps has an impact, entirely separate from glucose control, which could rise with older patients. Could age be a factor here? I’ve read that A1C tends to rise in older patients (links below). I’m 37 years old. My doctor is 35 and she says the same thing, her average blood sugars are 138 and her A1C is 5.4 --> much lower than the 138 average would suggest.
Just thinking out loud. Maybe my control hasn’t been that great over the years and I’ve benefitted from some other factor that keeps my A1C low. Clearly the amazing Dexcom technology with the accuracy getting so spectacular is making these things a lot easier to really dig in on.
