How long before you expect to be in target range?

If you inject your rapid acting insulin and eat how long do you expect it to be before your blood sugar is back in target range?
 
It depends on what's been eaten, but the general guidance is to test at 2 hours - 2 hours after the start of the meal, that is.
I go by that generally, but if I have any doubts about the need for a correction because of the content of what I ate, etc, I sometimes leave it a little longer.

Experience of the response to different meals helps a lot. I know roughly where my blood sugar should be after a certain meal, so if my 2 hour test is way different than what I'm expecting, then that's what I act on.

Edited to add that with an unusual meal or a high fat one, I continue to test as the rise can be delayed.
 
If it takes 4hrs to come down does that suggest the dose is wrong?
 
its all about the action of the insulin.........

novorapid is marketed to start after 15 minuted, peak at 1.5-2 hours, and gradually drop off to depletion after 3-5 hours....

everyone is different....
 
The dose is wrong if after the insulin has been in and ran out, the blood sugar is above the intended target....
This is what I thought thank you. Just trying to understand why the nurse wants to up doses when it seems the insulin just doesn't work fast enough

In long term diabetics, yes usually. But your daughter is honeymooning probably, so that complicates things. Enough insulin to get her back into range at two hours might cause a hypo if her pancreas contributes insulin too.

Erratic blood sugars aren't uncommon early on, so tweaks are more frequent.

It's a hard balancing act, especially with very young children who are usually on tiny doses. All you can do is try and monitor.
 
The time it takes for you to get in range will also depend on where you are starting off from - so if you are high and are bolusing a correction dose and insulin to cover your meal that's going to take longer to work because the higher you are the more insulin resistant you are. So when I give correction doses I give my pre bolus longer to work before I start eating, I wait til I'm on the lower side of in range to start eating, the insulin is working when I eat, it attend the spike and let's me plateau early. That's the theory anyway. Works most days with meals I'm familiar with, so long as I'm not stressed, or I'll, or hormonal...

Yes that's the approach I take too but still doesn't work :(

Novorapid. More like Novonotsorapid in my case. I find it is quite a slow action for me and is often still dropping my BG 5.5h later. So I try and dose 20-40 mins before eating to give the insulin a head start, reduce the spikes and prevent later hypos.
