Hi. I've just had a libre 2 fitted this morning and twice the alarm has gone saying my levels are below 4, on checking with finger prick i was 5.3 and 6.0 . Confusing stuff ?
It is common to take 24 to 48 hours for Libre (or any CGM) to bed in. Some bodies are not happy having an alien object inserted into their arm.
Ahhhh Thankyou, makes sense . Really looking forward to having a little more freedom and less finger pricking LOL
If your Libre doesn't settle, it is worth contacting Abbott (their 0800 number is on the Libre box and their website) to report a faulty sensor. Unfortunately, it does happen but most of us find most of the sensors are accurate enough and very helpful.
I had it fitted at 11 am yesterday so will give it today and see if it settles. On the plus side, i didn't catch it in my sleep so bonus 🙂 .
These may well be compression lows if they are happening whilst you sleep. Unfortunately if you turn over and lie on the arm with the sensor, the pressure placed on the tissue under the sensor causes it to register an erroneous low reading. Gradually you learn to place the sensor in a better position where this doesn't happen and also not to lie on the sensor arm, in the same way as you learn not to roll out of bed, but it takes time. You can usually tell if it is a genuine low or a compression low by looking at the graph. A genuine low will usually be a slow steady decline towards the red line whereas compression lows will show a sudden dip. Obviously don't ignore a low alarm and double check if you think it could possibly be genuine but take into consideration your sleeping position when the alarm wakes you because if you wake up on that side and the graph shows a sudden dip, it is likely a compression low.
Thankyou . Last night was a peaceful nights sleep with no alarms 🙂 x
Good! I'm sure everything will be fine now. Its always the first 24 hrs that are iffy on a sensor. Also your sleeping self may just need a week or so to remember not to lie on the sensor
thanks. not impacted (at least not yet) this is where keeping a spreadsheet comes in handy as lot #s are among the values collected
But it seems not all sensors in that lot. I have 2 from that lot, 1 still unopened and 1 that I've been wearing for a week. I put both sensor serial nos into the Abbott website, which told me my sensors were not affected and I could carry on wearing them.
