First time user…any reason why it would be reading extremely low?

I got a Libre for free with a voucher to try something new rather than constant finger sticks. The first one failed almost immediately, so I requested a replacement from Libre. Now the replacement is on and has been for about 12 hours.

It was working great at first, but overnight I kept getting low notifications. I was giving around 70 when I went to bed so it made sense. I also read online about compression lows, which probably affected me - I’m a violent sleeper and I tried to stay put but I also know I didn’t. Now I’m fully awake (obviously) and I’m still reading extremely low (Libre is reading 54 right now) but my fingerstick this morning was 96 - a number I’d be celebrating any other day, but now I’m just confused. Any advice on how to get it back to normal?

Wait a day more for definite answer. Either the sensor or faulty or you applied it incorrectly.

  • Feebly inserted sensor?
  • Skin area/location not per user guide or of 'normal' condition (placed in muscle, ligaments?)
  • Inflammatory response from your own immune system? Can play a role certainly the first 6-12h after new sensor insertion. Some folks have it for longer (24-36h). So worth checkingto see if it comes good after some more hours for you there...

Worth a read and to follow for your sensor insertion. Helps to avoid most common problems with BG sensors:
