In my unofficial opinion: Yes, Dexcom G6 transmitters lose accuracy as they approach their expiration dates. And I’m not quite sure if I’m the only one who has noticed this, or if others have also experienced this frustrating phenomenon.

I’m writing this after dealing with a dying transmitter that was showing its signs of decay by 1) losing connectivity with my receiver and 2) reporting inaccurate blood sugar readings. I’ve definitely narrowed the problem down to my aging transmitter, which (allegedly) had one session left before it was set to expire – everything else about this particular sensor session was standard procedure. And guess what else, everything about the entire 10-day session was obnoxious, because it was rare for me to have a single day with both accurate and consistent readings. Ugh!!!

I don’t know what’s more irritating – the signal loss or the inaccuracies. Actually, I DO know what irritates me more than anything else, and that’s the fact that the transmitters don’t seem to last for as long as they’re advertised. It’s just ludicrous, especially when you take into account how much these devices cost.

Many people with diabetes rely on this, and other forms of technology, to effectively manage diabetes. And when the technology can’t be relied on to do its job, we can’t perform our jobs as well. Diabetes is draining enough – is it too much to ask for technology to be trustworthy?
