last month my endo put me on a 2 week trial of the FreeStyle Libre Pro sensor to see how my BGs were doing. usually he just down-loads my pump and my meter on his computer; but this was, for me, a very exciting experience. i was told that it was waterproof and that i would be able to swim with it on w/out a problem. well, this first session, 14 days and nights, went really well. it provided a ton of info for my endo to work with.
i don’t use a CGM anymore, for personal reasons, so this was a way to collect data that otherwise might go unnoticed (my over-night BGs, for example)
well, after downloading it after the 2 weeks, he saw that my basal rates were much too high, and he had me re-program my pump settings. very dramic changes. so, in my wisdom, i thought that it would be VERY helpful to wear the sensor for another 2 weeks so that i could see how i responded to the changes. my insurance wouldn’t cover it, so i payed OOP ( very $$$$ at $350) . i discussed it with my husband and we both felt strongly that it was a very worthwhile investment.
so the nurse hooked me up, again promising me that i would have no problem swimming with it and to come back in 2 weeks so that it could be downloaded. well, i did NOT get my money’s worth. after the first week, it peeled off in the swimming pool. i tried pushing it back in, but it didn’t stick. so i called my endo, and he instucted me to put it into a sandwich baggy and bring it in with me to our next scheduled appointment.
i really thought i should get my $$$ back. i mean 7 days does not tell a very clear story; at least in my mind. i wanted him to be able to see the difference between my swimming days and my non swimming days; my over-nights when i have swam hard and long, vs, just a moderate swim day. i wanted to see how these new basal rates were adjusting.
so, although it was, all in all, a helpful tool, someone should have warned me that i would have been better off covering it with some Tegaderm tape.it was definately Not (completely) water-proof.
