High Blood Sugar before bed

[Jackz79]

I have been finding recently that my blood sugar levels are quite high before going to bed. I currently take Humalog Insulin before meals and Lantus at night. I often find that my blood sugar levels can drop quite a lot during the night on my current levels of Lantus, but I'm obviously keen to reduce my levels before I go to bed. I'm worried that having lower levels before bed will cause me to have a hypo during the night. I just wondered if anyone else had this same problem or what people would suggest to avoid this.

The job of your lantus is to keep your blood sugars flat-ish when you aren't eating or bolusing. If you're lantus is at the right dose for you and you go to bed with no active insulin on board and no food being digested you shoul wake up within 2mmol of the number you went to bed on. If currently you find you drop more than 2mol overnight that might suggest you lantus dose is too high.

Lantus lasts about 18 hours for most people, so if you take your lantus to go to bed the high bedtime readings might be a reflection that the lantus you took last night has run out. You could consider splitting your lantus and taking one shot in the morning and one in the evening.

If I were you, I'd start out with a bit of basal testing just to see what's going on overnight with your lantus and whether you might need to consider splitting it - https://mysugr.com/basal-rate-testing/
