My levels always drop overnight but I find that my sensor alarm frequently wakes me with levels of 3.4 or similar. When I get up I don’t feel at all hypo and often my levels then go up even though I haven’t eaten anything. If I had those readings during the day I would definitely be feeling hypo.I've had a few issues with the libre 2 sensors. Yesterday and through the night I had the sensor reading as lo or 3.2 or beliw and was taking action to deal with the lows. It wasn't until I got home and finger pricked when I realised my sensor was reading at about 3.5 below my actual readings. So I was never low in the first place? This has happened a few times and not at the end of the sensors life either usually 7 to 9 days in? However I always report the issue to Abbott who have usually replaced the sensor. Has anyone else had this issue?
May I ask what problems you are having ?I never had any problems with the original Libre. Libre 2 is a nightmare. I don't bother with it anymore.
I dislike ' new improved' things, they rarely are as good as the original.
Sensors only lasting 11 days and being unable to scan when I want to...'try later 'multiple times a day. Abbott have replaced a couple of sensors for me, but it's just too much trouble to keep contacting them. Technology that doesn't work all the time is useless.May I ask what problems you are having ?
Do you check your readings with a finger prick?My levels always drop overnight but I find that my sensor alarm frequently wakes me with levels of 3.4 or similar.

The BG readings going up early morning could also be due to the "dawn phenomena", where BG rises on its own. That happens to me every morning.Do you check your readings with a finger prick?
If this only happens at night and your BG goes back up on its own, it could be a compression low - false low reading reported by any CGM if pressure is applied to the sensor blocking the flow of fluid to the filament.
I find it frustrating that this is something that is "tribal knowledge" amongst those of us who have been using CGMs for some time but is rarely shared by the manufacturers.
Plus the other common limitations of CGMs such as insertion trauma, predictive reporting and design calibration for normal levels.
I like that idea. I presume though that you still get the 1 hour gap between the first one stopping and the new one starting?It could well settle down after the first 24 hours and be more accurate. If not, give Abbott a call and they'll replace it. Some of us find it helps to apply the Libre to our arms 24 or even 48 hours before activating it.
Does the Abbott reader still give alarms forI learned to
- apply new sensors several hours before the previous one stopped
- always use the other arm for the new one
- always wait after swabbing the skin, to allow all the alcohol to evaporate
- during application, after pressing the sensor onto the skin, wait before withdrawing the applicator
- then press firmly directly onto the sensor to be sure it is fully and firmly attached
- as soon as the older sensor stops functioning, rip it off, so that I could not rescan it in error after starting up the other sensor (scanning both sensors really screws up the operation of the reader)
Since then, they operate perfectly. I never link my phone: only use the Abbott reader.
Try contacting Abbot direct. They will replace faulty sensors without affecting your prescription.Same, i have had to faulty one in the last month too. One kept looking signal and my phone was right next to it. The other unavailable to scan all the time. But GP only gives me 2 a monthback to pricking my finger for 3 weeks
Yes you do.like that idea. I presume though that you still get the 1 hour gap between the first one stopping and the new one starting?
