Question:
From Prodigy:
I am new at this (about 2 months now) and I would like to know what blood sugar is too low to take my insulin? I'm Type 1 and at times when I test my blood sugar it will be 89 or 85; at times it's 99. I just do not know what is too low; I do know that 200 or more is too high.
Answer:
My own advice about this is that you shouldn't miss insulin at all. You should always be about to eat when you are taking your routine Regular [or Lispro] insulin injections. The blood sugar before a meal therefore reflects the effect of the previous dose and not the one that you are about to have. If you are regularly low at a particular time,
then you should consider reducing the previous dose or increasing your food intake after
it.
If you have a low sugar before an injection then you should still take the injection but eat immediately (a fast acting carbohydrate followed by your regular meal); i.e., don't leave the usual gap between your injection and food.
