I had my second failed sensor this week. It looked perfect, no issues from looking at it. Wasn’t even starting to come off. It had been on for 9 days out of 14. I woke up around 8:15 am and it read 5.2. That’s about where out should be and I was proud of that. Since getting hurt my blood sugar has been a little high.
About an hour and a half later it showed 11.5 and going up fast, oddly enough I hadn’t even eaten yet. I scanned again just to be sure and it was 12.4 and rising fast (the arrow straight up indicates it’s rising fast). I decided to use the test strips for the Libre and it showed 8.8. I knew then something was wrong with the sensor.
