CORRECTION FACTOR OR INSULIN SENSETIVITY - HOW OFTEN

[mum2westiesGill]

What's your correction factor (also known as insulin sensitivity)?
How often do you change it?

Mine is 1 unit of fast acting insulin to drop me by 2mmols
It's not been changed for probably donkeys years.

I know to work it out you do
100 divided by TDD - total daily dose of all insulins (bolus & basal) equals ? and this number is what 1 unit of insulin drops you by when you do a correction dose of fast acting dose for high BGL.

0000-0700 1:1.8
0700-1100 1:2.3
1100-1900 1:2.8
1900-2100 1:2.6
2100-0000 1:2.3

Not sure how they’ve ended up like that, we didn’t always have so many different ones, and they don’t change very often, but if we find either we’re always going low after a correction, or the correction never quite gets us back into range, then we tweak it for that time period. It’s all set up on the pump and the pump does all the calculations, that’s why it’s weird numbers! Just changing it by a tiny bit can make quite a lot of difference!

Why are you asking? If 1:2 works for you then that’s all you need to know!

Hmm, I’d never really thought to work it out mathematically, or to update it, however I’ve always I’ve always worked on 1 unit generally takes me down 3mmols. As always not an exact science as who knows what else is going on to affect it at any time...but this generally works for me.

The rule of 100 just gives a rough idea. It doesn’t work that well for me. Go with what works for you.

My correction factor is 1 unit brings me down 4 mmol most of the day, 4.5mmol late afternoon and 6.5mmol at bedtime when I seem to be ultra-sensitive. That’s why I generally try to avoid corrections late in the day.

That formula doesn’t work for me. It works out as 1 to 4 for me, when I know that 1 to 3 works. So stick with what works for you. Total daily dose varies so much by how active you are, what your diet is like (ie, carb heavy or carb light), whether you have any of your own insulin production left, etc etc.

I'm just asking in general really. Tbh I've not paid any attention to if it's working for me but I guess I probably should do

100/TDD is just a guideline to start you off, then you tweak it from there if necessary. Which is probably how my daughter’s has ended up so complicated, it’s gradually been tweaked over many years! For a long time it didn’t change at all though, I don’t change it very often. It seems to work 🙂
