Re: [IPk] Excercise causing high BG level
I am fascinated. I don't think I could eat 60g of carb without insulin and 1
hour later not have risen so little. I'd be massively high within an hour. Do
you absorb food very slowly or am I weird?

Sounds perfect. But I actually still need some of that missing insulin to cover
the carbs for lunch, which continue to have an effect on my body for the next
few hours (since the action of the carbs is several hours, not just 2 hours). So
I have to then bolus 1-2 units when I finish the class, to cover that missing
insulin I didn't take with my lunch.

with exercise is to not reduce their insulin early enough, and/or to end the
reduction of basal rate too late (after you've finished the class is already too
late - usually putting the basal back to normal at least 30 minutes before the
end of the class is better).

suggestion is to take a small amount of insulin immediately after you finish the
class. I find it better to do this as a square wave over 30 minutes or so, for
the simple reason that if you find you don't need it after all and start going
low, you can at least cancel the rest of it.

it'll take a bit of experimentation. It's taken me a long time to figure all the
different food and insulin requirements for the various different sports and
exercise I do, and it's different at different times of day.
