Hi, just started using freestyle libre on Thursday (I realise that's not long). However finding it a bit frustrating. First night I had it, it said I had a below 3 hypo during the night, which I didnt feel or wake up during....so was scared, I'm fairly newly diagnosed and never had a during the night hypo yet (to my knowledge).
So last night I set an alarm for 1:30, scanned libre 4.2, finger pricked 6.8.
Today 12:00 scanned 4.2
, finger pricked 5.8.
I realise there's a lag, but am I being a bit unrealistic thinking this is quite a variance? Could there be something wrong with the libre, does it take time to bed in, etc? Thank you.
How closely does it correlate during waking hours?
If you sleep on the sensor, there is a theory that the pressure pushes interstitial fluids away from the needle so it has less to measure and will thus give a lower reading.
