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.

Alyssa, absolutely the thighs work well. For the past year, I have placed mine on the front of the thigh (not either inside or outside, but front), about the height where if I put my hand in my (male) jeans pocket, I can just reach the transmitter with my fingers and thumb. This way it doesn't chew up valuable pump space on my abdomen, and avoids stretch marks there. And even though I sleep on my sides, I don't ever sleep directly on the transmitter or sensor. I usually get 2-3 weeks out of the sensor this way; more if I use additional Hypafix tape once its own starts to get ragged. My accuracy in this location is completely marvelous, and has been for a year.

Alyssa do you use your upper abdomen, that is were I place mine. I have know issues with the transmitter and sensor staying in place. I'm very thin and also limited on locations. Use some skin tape to secure if that makes you feel more comfortable, several brands on the market.

Comment by Alyssa yesterday
I just had my first wasted sensor :( for some reason I am having adhesion issues (even my infusion set is acting up). I am going on a little weekend getaway and don't want to be stressing about losing another sensor! After inserting it and putting in the transmitter it just fell off. I am limited on available real estate here as I am completely covered in stretch marks. Any tips on using thighs as a site? I know it's not recommended but I have to try something. I should note I do have skin tac to help

My daughter has the dexcom g4 and it is great! It was a life saver to us. I can actually sleep and try not to worry so much. She had it for 6mons now and she said she likes it too. It is so hard as a parent of a child that has type 1, thyroid, and now is gluten free. She is 10 and has been through a lot! She takes everything with a grain of salt!

Thank for the input. It is all very helpful.

I agree. It is such a useful device!

It's hard being disconnected from the Diborg Collective. Hope you get yours soon, lh378. :)

I agree with Elsa, when my BG falls from 180 to even 110, I can feel terrible and jittery. Whereas for the past few days, I've stayed between 70 and 120 with only two readings outside, 160 before exercising (I did not bolus because I expected an intense workout) and the subsequent 60 after exercise. (I am in the process of obtaining my own Dex after a 1 week trial. So presently without a Dex :(.

Hummingbird, I rely on my body's reaction to dropping bg. If blood glucose falls rapidly, it makes me feel similar as actually having hypoglycemia. Just test often during these times. Sometimes patience is what we need if we know we've already corrected a high or low with insulin or food.
