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 used Libre 1 for years, they work reliably. They will usually fail in the first hours of use, but otherwise work well for the 14 days.
Always keep a standard glucometer at hand, because these monitors can be affected by temperature and humidity.
