I am very interested in alternative sites as well. I think a better approach to this post would be to describe what the alternative areas are like, because one person's thigh may be nothing like the next's, and whether the Dexcom works well there are not depends more on the tissue it's in than where on the body it is. Dexcom works pretty well on my abdomen, except in the summer, not quite sure why. I've never been able to get more than 10 days out of it though like some people. I have a pretty lean abdomen, muscular, but still have a small "diabetes" pooch under my belly button, and I've found I get the best and longest lasting performance when I put sensors there. I just now put a new sensor on my upper inner thigh, which is the softest (most pinchable) part of my thigh. My theory from my abdomen experiences is that the dexcom likes softer places (like maybe with more fat), what do y'all think and how does it match up to luck with alternative sites?
Lower back horizontal is a winner. Soft tissue and out of the way.
As for Dex liking softer places with more fat.......I am a 'fluffy' person and when
I had it on my fluffy spots, abdomen, my readings were way out of whack. Someone suggested using my thighs(not 'fluffy') and now my readings are much better.
My favorite spot is on my upper arms, on the top of the arm near where the arm meets the armpit. To put it on one-handed I sit sideways in a chair with no arms and push my arm against the back of the chair to simulate pinching it up. It does help if my husband is there to help rock the inserter forward to remove.
On my arms, I have the most accurate results with no ??? (knock on wood!). In the location I described you can't see the sensor under a short sleeve shirt either. I honestly forget even which arm I have it on. I'm careful when pulling a shirt off not to dislodge the sensor.
I've also used the inner thigh successfully but found it more bothersome when changing pants, going to the bathroom, crossing legs when sitting, and just more aware that it's there. The accuracy was good for me on the thigh though.
The least accurate place in my experience has been my abdomen. I don't mind wearing it there; it just doesn't seem to work as well there for me...lots of ??? and inaccurate tracking of numbers.
I really like the arm too. I usually put it halfway between my armpit and my elbow cause there's a little more "meat" there. I just go from one arm to the other. It's placed directly on top of my arm and never seems to get in the way while sleeping, etc.
