Time for Novarapid to start lowering BS

[sgm14]

Another in the long list of things about diabetes that I don't understand.

Unless my BS is very high, I never inject my insulin more than about 15 minutes before a meal, otherwise I risk going low before the carbs kick in, which means that my Novarapid must quite often start lowering my BS within 15 minutes and can often cause a 2-3 point drop within 30 minutes.

So why does it almost always take more than an hour for a correction dosage to start lowering my BS and usually takes 90 - 120 minutes before it will drop 2-3 points?

I was wondering if anyone else experiences this or has an explanation?

I feel your pain. Not using novorapid (also referred to as novosluggish by some on the forum) but I find that once my bg is too high I become more insulin resistant and everything takes longer to act.

I'm using humalog BTW.

Interestingly.

Novo slug don’t apply to me..
The times I’ve gone wayward (talking in the 20s?) & need to correct I’ve seen a turnaround in under the hour & need to under calculate the correction dose by at least 1 unit or I plummet like a stone & almost feeling hypo when hitting range??
(Especially if busy at work..)

That’s interesting. Would that mean that some people are more insulin sensitive than others or maybe it depends on time of day?

I use NovoRapid in my insulin pump. In the morning I inject 30min before breakfast and my bm stay good. However, I can't do that with lunch and dinner. I need to inject as I eat. Or go hypo.

If my bmi goes above 14mml, my resistance goes high.

Personally I think it depends on many things , sometimes I can inject 20 mins before and I’m fine sometimes I can take it 20 mins after and 3 hours after if I eat spag bog too many variables to actually give an accurate diagnosis but that’s just the things we have to do what was it Forest Gump said about life being likea Box of chocolates

Hello, everyone. My experiences are similar to @sgm14 when my glucose level is below 120.

But when it's above 140-150, it's a big problem for me. If you eat a lot of carbohydrates at once, it will go down, but it may take an hour or much longer (2, 3, or even 4 hours). But if I eat only a few (for example, if my breakfast is 6 carbohydrates and my glucose is at 160), my glucose will never reach an optimal level for eating. Because I use the pump in Guardian mode, and as soon as it sees an insulin bolus, it stops injecting basal insulin, and of course, the amount for the bolus disappears and is used as basal insulin. So what do I do? I wait to see if it goes down somehow. But when it's at 160, it stops injecting basal for a long time, and then there's no insulin left from the bolus I injected to eat.

Also, in Guardian mode, when I am administering insulin for a meal, if I exceed 10-12 carbohydrates, it starts reducing the dose. Sometimes it gives me less than 50% of the insulin planned for that amount. After the meal, it takes a lot of time trying to bring the glucose down to a lower level (because, in my opinion, it made more reductions than necessary in the amount of insulin to be injected for that particular meal) and finally (7 hours later) it ends up asking me for blood. But it doesn't inject more insulin neither. Maybe It is not learning.

Today, I have hardly eaten anything, and my glucose has remained around 160 for many hours. And after 7 or 8 hours, it asks me for a blood glucose test. In non-Guard mode, I would have lowered it, but my endocrinologist have been told to let it learn, although I don't know if what I am doing is teaching it bad habits.

Rather, it seems that it does not believe the values it obtains from the sensor. And today, the sensor values and blood glucose values differed by only 1. That's what I call a good sensor.

Best regards to all of you.
