I know I've harped on this in the past, but I really hate having high blood sugars. Given the choice, I'd almost always choose to be too low than too high. It's not so much the feeling of the high . . . I think it's something more psychological than physical. Highs feel like I've failed. (And yes, I know that's not true. I'd be the very first one to tell someone else with a high reading that they are not a failure and it isn't their fault. But when it comes to me, I forget that fact.)
When reviewing the list of things I dislike about exercising, it stands to reason that blood sugar management would be very near the top. Specifically, I dislike the feeling that I need to boost my blood glucose up high before beginning a workout. Instead, I try to balance things out with temp basals and/or strategic meals or snacks. I'm stubborn that way. I refuse to send my blood sugars soaring just so I can exercise.
But as we all know, highs do happen. I battled them all day yesterday, and all night as well. No sooner would I get back into range than they'd start to soar towards the heavens again. After some major corrections and a higher temp basal, I woke up this morning to this . . .
Not the worst fasting number, but certainly nowhere near the range I hope to be in first thing in the morning. However, since we were starting Week 5 of Couch to 5K this morning, I decided to forgo any correction bolus and see what my run would do to the number.
In all honesty, the run actually raised my blood sugar slightly. (Maybe I had some ketones going on, but it's more likely the fact that exercise sometimes makes my glucose rise a bit before it falls.) Once we got home, I took the correction that my pump suggested and was at a happy happy 107 before breakfast. BUT the important thing about my run this morning was that it felt AWESOME!! We had progressed to a harder level, but I felt great. And I'm wondering if starting with a higher than usual blood sugar had something to do with it? Or if I just had a good day, regardless of glucose levels?
I know a lot of you have much much more exercise experience than I do, so I'm asking for your advice. Do you run yourself higher before a workout? Do you find it helps your performance? Do I need to change the way I look at pre-workout blood sugar readings? Or do you see that as counter-productive to the goal of blood sugar management? Do you just try to time insulin and food strategically to get through a workout without plummeting too low? Should I just keep doing what I've been doing all along?
