Hi I just joined the forum. Long-term Type 2 on insulin for about ten years now and may be LADA now, endo is going to check at follow-up. In my 60s. I started the Dexcom G6 and what I found what that while it may be good for patterns, as far as actual bg readings it is always way off from my meters, over the 20%. It didn’t even record some postmeal high curves but just flatlined. All the Dexcom readings are much lower (for instance, this morning delayed fasting - in which my bg will climb considerably until I eat breakfast - fingerstick was 183 while Dexcom was 139. This was very disappointing to me because it was the data I was most interested in, not reports and so forth. My POC at the endo clinic used the code to calibrate it and I think this was the issue. Next sensor I am going to use manual calibration and see if that makes a difference,. Has anyone else had this issue?
I did some research online and found that generally alternate sites do not do well at determining bg, so I have to assume their code-based calibration algorithm is crap. I would really like to get some use out of this, it was expensive, and hope that manual calibration works better (I will post results when I have changed sensors).
Also I find it ironic that Dexcom advertises no fingersticks when they then say don’t rely on it for insulin dosing, fingerstick for that. (I don’t have an issue with fingerstick, I use the sides of my fingertips which causes no issues)
