Anyone wear one on their arm? I might try one to see how my body reacts to the food I eat.

My wife has/had the dexcom, she puts it on her upper chest, this avoids knocking it off by accident... still records properly, she recently suffered a severe allergic reaction to the glue on the sensor, we thought it was shingles at first , so has temporarily stopped wearing it and she's now waiting for her doctor for a recommendation...

the sensors are not exactly the same as a blood (This word is unacceptable on Trapperman) analysis, but are accurate to itself so seeing the highs and lows is close enough.
One cool thing is the sensor will alert you to high, or dangerously low readings...

I have the Libre 3, I’ve used the Libre 2 and the Dexcom, I really like the Libre 3 but I would take the Dexcom over the Libre 2. Libre 3 lid a little more gentle on out of pocket cost too vs the Dexcom for me.

My wife has dexcom. WE LOVE it .Been 2 times we KNOW it saved her life. I was on lake at night .I got a low notification on my phone her sugar was 65 and dropping fast. She has a severe hearing loss and with out aids doesn't hear ANYTHING.. I tried calling her cell house phone nothing. Called my son who went to our house. She was still sleeping and sugar was 48 still dropping. Best thing I see about dexcom versus libre is you don't have to hold phone up to device. She wears hers on stomach just above her belt. Back of arm if she wants a break from stomach
