High morning readings

Hi I have had high morning reading that seem to vary wildly (11-1

Cant seem to get a correlation between my night time long term Levemir + Novarapid adjustments

Anyone have similar problems

I can control the other times reasonably well as long as I'm aware of carb value of what I'm eating

what are your readings before bed? If the long acting is working right then your reading won't really change in the morning. If you are correcting with Novorapid before bed and you are still high in the morning, that suggests your long acting is not enough. LIkewise if it is low in the morning your long acting is too much.

I only find my bedtime levemir is predicable if i have absolutely no humalog or food (evening snack!) in my system. If either of those are in my system it doesn't matter how predictable the levemir is because my morning BG will often show no relationship to the bedtime level!

If I have to correct at bedtime that obviously doesn't help because of what I've said above - and over the last couple of weeks I think I've worked out that any bedtime correction needs to be a different ratio to the rest of the day. So at bed 1 unit brings my BG down by 2, during the day it's 3.

Well that worked last night anyway...

Hi, always had the same problem but reajusted the time I took my lantus. I'm just about to start on levemir. I'll let you know how it works out.

Are you going low in the night without knowing?

Hi Mark,

Others have given you some really good comments / suggestions.

The reasons for high morning BG may be:
High BG at bedtime that's not been corrected
Late meal/CPs not sufficiently covered with QA
Bedtime dose of BI not high enough
Bedtime dose of BI 'running out' and not strong enough to counteract the Dawn Phenomenon

Contrary to previous beliefs / advice, research has now proved that it is highly UNLIKELY that a high morning BG is the result of sleeping through a hypo.

Levemir is one of the better insulins for controlling morning BG as it has a fairly 'flat' action and longer duration than isophane insulins, however most people find they need relatively high doses of it and it is best to take it as near to bedtime as possible (rather than at evening meal time).

So if your bedtime BG is in target (6.5-8.0mmol/l), a good 4-5hrs after any carbs or QA, if your bedtime Levemir dose is right your BG should remain stable overnight (with an expected natural dip around 3am which shouldn't drop below 4.5mmol/l).

Hope this helps.

Good luck,

Carolin
