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.

Dexcom is a ware of this and they REFUSE to work with MACs. They also REFUSE to work with DiaSend. I do not know if the problem is Dexcom or FDA (Fools, Dummies and A.... ).

I am so amazed the software doesn't work on my MAC. Yikes what a pain.

Thanks Luca, I think :(

Unfortunately there is no way to do that. Been there, tried everything, no luck. Even by fiddling with the data it won't work, as there is a level of encryption used to provide anti-tampering to the data.

You'll have to create a new profile and start with fresh data.

Ciao, Luca

I've asked previously, elsewhere, but never got a solution.

Can anyone figure out how to merge the databases from 2 different receivers? When I called Dexcom they said it's not possible. The person I spoke with didn't even know where to find the dbs or what type they are. Any help appreciated!

I put a sensor in my arm last night and it is working fabulously! Thanks everyone!

You guys inspired me. Just changed my sensor today and used my arm for the first time. Seth, thanks for the video. I ended up with it mid-arm towards the inside - so far, so good. Readings are awesome already.

Thank you so much! I will have to go ahead and try the arm and thigh. Thank you Lisa C and Manoah!

I have used on my upper thigh( quad area) and had good result. the back of arm ( tricep) did not work for me as I am a swimmer and it went bad after 4-5 days. Probably too much movement? Also difficult to do on ones own. Find a loving assistant for arm.
