…this keeps happening on Day 9 of wear:
I don’t understand why the sensor error occurs. But it almost ALWAYS happens on the ninth day: My sensor will work wonderfully and provide me with extremely accurate data, but then BOOM it’ll sporadically stop working and produce graphs like the one above that are virtually useless. Even worse, there’s no telling when exactly it’ll start communicating again with my receiver. The error message SAYS I’ll get data back within 3 hours, and I normally do, but there’s a big difference between going 10 minutes and going 2 hours without any readings.
This device has so many good things working in its favor: longer wear, painless insertion, increased accuracy, compatibility with acetaminophen, slimmer profile. But I’m of the opinion that if something says it will totally function for a certain length of time, then it WILL. The fact that it doesn’t, and that this has occurred more than once to me, is alarming and frustrating.
The only possible explanation I’ve come up with is that maybe the upper arm isn’t a great place to wear the G6. As we all know, Dexcom devices are FDA approved to be worn on one location, the abdomen. However, that hasn’t stopped the cheeky diabetes community from wearing it elsewhere. Besides the upper arm, I’ve seen people with it on their forearms, thighs, and calves. I even know one clever person who chooses to wear it on the upper bum during the summer months to prevent tan lines (hilarious and brilliant, IMO). I choose to wear my CGM on my upper arm most of the time because it’s comfortable there, and I like to give the sites on my belly a break. But maybe it’s time I start wearing it more frequently on my stomach, the “officially okay” site, to see if that prevents these ridiculous sensor error scenarios.
What I’d like to know in the meantime, though, is has this happened to you or anyone you know using the G6? Has anyone pinpointed a cause, and is it worth notifying Dexcom of this issue? I’d love to hear your stories and thoughts – drop a note in the comments or get in touch with me directly!
