Overnight Hypos

My partner has type 1 and uses a Libre 2 monitor. Regularly she will have a hypo overnight - typically her blood glucose will reduce in a more or less straight line at around 2.2 to 2.4 mm/l per hour. To avoid a hypo she effectively has to go to bed with a reading of up to 20mm/l. She carb counts and splits her long acting morning and evening.
Given the continuous rate of glucose reduction I can't see compression effects on the Libre sensor being relevant or an effect of her last short acting injection. I assume this points to the number of units of long acting she is taking in the evening but she's only taking half the daily amount and reducing by 1 unit makes no difference.
I'd be very grateful for anyone else's views or experience

Hi @Europa01 and welcome to the DCUK forums.

The first recommendation I would make is that she contacts her medical team urgently. This is the sort of issue they should be advising on.

What kind of long acting insulin is she using?

Hi EllieM - thanks very much for your quick response - she's using Levemir but about to be moved to Glargine. Your advice is noted and I'll have a serious word with her.

I used to have quite severe nocturnal hypos until I changed from giving my long acting insulin at night to when I wake up in the morning , I haven't had a night time hypo for over 5 years now .

Hi Jawak - thanks for the prompt advice - as she's going to be moved to Glargine a single morning injection may suit what I understand to be its 'long tail' effect.
