Dexcom Users

For users of a Dexcom Continuous Glucose Monitoring ("CGM") device

Just as a reminder with the recent release of the new Dexcom G4 to the US market--it is NOT okay to post about previous models or older sensors as being 'for sale' on this site.

It is a violation of the Terms of Use because it is a prescription device, and any such efforts will unfortunately be removed.

We encourage you to donate supplies to non-profits such as the Charles Ray III Diabetes Association (, which accepts unexpired glucometer and insulin pump supplies, or alternatively you may talk to your physician's office or other local medical group to discuss donating them to those in need of assistance.

Thank you all for kindly refraining from this activity.

cody, I to feel lost what my sugars are, but then on the other hand, my G4 is not accurate most of the time, My first sensor I had on my stomach, lasted 10 days, now I have it on my thigh hoping I will get more accuracy from it and hopefully last longer since I pay out of pocket, but so far I don't see the benefit I was hoping from it, if it is not accurate most of the time then how can it help me or the doctors. Just hoping I am doing something wrong so it can be adjusted. LOL

Steven what problems were you having with the buttons?
I have issues with that, and accuracy issues.

Does anyone else feel lost during the 2 hour start up period for the sensor? I know i hate not knowing what my blood sugar is doing during that period besides doing a finger stick

I just got off the phone with Dexcom and they are replacing my receiver for the second time to investigate why the buttons are not working. They want you to call them with these problems and told me that if anyone is having the same problem to call them and let them know.

I used to have the button problem as well (dealt with it for over a year, I even posted in a thread here somewhere about it) but then I got my new receiver (Software Rev and the problem is gone.
I actually didn't notice it until this week when I switched back to my old receiver (revision number: to see if my sensors last longer with the old software.
Now the old familiar middle button issue is back!

Similar issues with mine.

Comment by SS on March 19, 2014 at 9:43am

I thought maybe I was imagining it, but I also noticed that sometimes I have to press twice to wake it up. Hoping it doesn't become more of an issue as I continue fall even more in love with Dex.
