    I have otherwise pretty much perfect blood sugar, so a compression low is a little annoying. I did not wake up in the night.

    I do not want to decrease my basal as currently I'm only on 5 units of Tresiba 24h and that already seems very low. However if it's likely that's a real low, I will probably decrease it to 4 units to avoid the lows

    Hi @Hannah Robyn

    That does have the familiar pattern of a compression bounce, I tend to go by how I am feeling too so do I feel a bit groggy. I also don’t adjust insulin based on one off readings i’d act on this if I saw a repeat pattern to verify first ;)

    Assuming you slept through it and didn't need any hypo treatment for the rebound, it is most likely to be a compression low.

    Looks like a likely compression low to me, especially because it looks like you have been quite stable through the night and the line just makes more sense the way I've drawn it in your graph.

    Very nice catch after that steep drop before bed, well done!

    I thought the libre 2 had alarms? Doesn't it wake you for night time hypos? If so, you could verify with a blood test....

    It looks like a really steep drop, but i was only dropping from 8.8 to 4.5 over 2 hours (my graph on my phone is pretty spikey and makes it look way worse). Libre makes it easy to catch drops!

    Maybe set up the alarms so you can check whether the night time low is real...
