What is a bad BGL after intense exercise like ice hockey. I am usually up around 189. I understand why, but do I need insulin?

Dear schufgb7,

Whether you need to take some insulin or not after an intense activity that causes it to go up depends on your own regimen. Do you usually eat after playing hockey? If so, you will need some insulin to cover what you eat, but usually it will be much less than your normal amount.

Whether you should give insulin for a blood glucose level of 189 also depends on the time of day and how much insulin you have taken up to that point before playing (since it sticks around for as much as 6-8 hours, even when it's mostly gone in 2-3 hours for most rapid-acting doses).

If your level is anywhere below 200 after playing, you may want to wait it out (if you're not eating) to see how quickly it comes down on its own without any insulin. If it doesn't, then you may want to give a very small dose of insulin to bring it down (half of normal or less for that type of correction). If it's over 200, it may be worth using a bit of insulin to lower it more quickly.

Remember that your body is very insulin sensitive for a period of time after exercise, and the first 30 minutes to two hours is probably when you need the least extra insulin to make it drop. Giving too much then can also cause a precipitous drop and low blood glucose levels later on.
