I wrote
last month about my diabetes diagnosis this year and my
difficult choice to wear a proprietary device (called a
CGM) on my arm 24/7
to continuously monitor my glucose levels. Like my friend and colleague,
Karen M. Sandler — who previously made a much higher-stakes choice to
receive a proprietary implanted defibrillator to keep her safe given her
genetic heart condition — I reluctantly chose to attach proprietary
hardware and software to my body.
I’ve found this is really dependent on placement. If I put my libre a couple of centimeters away from the region I usually use, it’ll read low all night, but as long as I stick to the zone I’ve determined to be fine, it’ll agree with a blood test even if I’ve had pressure on it for ages. Also, the 3 is more forgiving than the 1 or 2 because it’s smaller than the older models, so affects how much the skin bends and squishes less.
