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.

Cool photo, thanks for sharing it.

All the G4 systems are essentially the same. The difference is mostly a few added screens to the received for the pediatric version. It does also seem recent receivers ship with a new firmware and algorithm (this based on their reported different behaviors in some '???' conditions) but the parts are physically the same. My son was a bit aware of his sensor the first week he wore it but even though he is very active, he has never experienced pain. The wire that goes in is very thin and flexible. Here's a macro shot of it (about x20)

As a followup to the questions about shifting, moving clothing and physical activities, is there a difference between the G4 and G4 Platinum?

Comment by lh378 13 hours ago

Wow, those are all very strong testimonials and really positive feedbacks about the Dex CGM. I'm almost towards the end of my 1 week trial of the G4. Just a few times, I've felt a slight pain when my pants shifted (the G4 is on my abdomen). What are some of the learning curve involved in movement and activities and tight clothing or loose clothing to minimize pain.

Lisa C, I did the same thing! It was a horrible experience. I absolutely love the G4. I have never been happier with my Diabetes management! I think having a CGM made by a company that does nothing else makes all the difference!
Comment by lisa c yesterday

I did switch to MM so as not to have 2 devices. I wanted to make it happen. After 4 months of frustration, endless tech support, I sent the system back and got another Dex. PLease do not waste the time, cost and energy.

Comment by Rodger yesterday

I agree with the others regarding Dexcom's accuracy. See PierreV's comment and link below to a study that confirms it. The only reason to consider the competition is that you can't live with two small devices, and want just one. And now that the Dexcom CGMSs are being built into some insulin pumps, that constraint will soon be a non-issue.

Comment by Clare yesterday

I wouldn't waste my time trying the only other CGM available in the US which is a Medtronic device. The G4 beats it in every category hands down.

Comment by Michael Watson on Sunday

I've used the G4 for over a year, and I really can't imagine not having it. I accidentally left the receiver at home when I left for San Diego Comic Con this year, realized my mistake on the plane, and got a friend to FedEx it to me rather than not have it for five days. Totally worth the minimal hassles.
