Night-time highs

[EmmaK_2907]

Last month, I started on the Medtronic 780. It’s working really well during the day - sugars are almost always in range. At night time, though, I am having a real nightmare! My sugars are rising and despite numerous correction doses, they just don’t seem to come down - if anything, they continue to rise. Lots of beeps overnight, a few hopeful set changes, twice I’ve disconnected the pump and done a pen injection in the wee hours. Driving me up the wall!

I’ve tweaked my carb ratios for my evening meal (and the few hours before). I’ve also reduced the active insulin time. Regular contact with the diabetes team who seem as much at a loss at to why this is happening as I am.

Really love to hear from anybody else who might have had this? Or any suggestions! Most nights, my graph is almost solid blue with corrections. And I am stupidly tired and cranky!

Have you tried when you are getting high blood sugars overnight to test your blood sugar, enter the value into your insulin pump and check to see if it is suggesting a bigger correction than it is currently giving in micro amounts? The pump takes your previous 6 days insulin amounts into account to then decide how much it will give at various times in the day, with you disconnecting and giving a manual injection it hasn't "learnt" that perhaps you need more overnight than it is giving.

I've also heard of people going back into manual mode for a week to retrain the algorithm and let it learn again what your insulin needs are.

As a final note, have you thought about swapping to a faster-acting insulin if you're not on one already, I was on Novorapid previously which really struggled with bringing my sugars down but Lyumjev has helped massively with that as it begins to work a lot faster.

I do get similar, particularly in periods of stress. I increase the basal profile from 9pm, then if required, a correction about 10.30. Generally this works but not always.
