Wednesday morning, I woke up at 5:15am with a blood sugar of 219, thanks to a serious steak dinner the night before. I didn’t bolus, but suited up for the gym, made a cappuccino, and went to a kickboxing class for an hour. I came home to a friendlier blood sugar of 150mg/dL
We all know that working out can send you low sometimes, and that you’d never want to workout when you’re already low. But highs? I have quite the upper threshold for working out with a high blood sugar. I’d have to be over 350mg/dL and spilling ketones before I took my gym shoes off and canceled a workout. In fact, I’mmuch more likely to take a half unit to bring down my BG over the course of the workout more quickly rather than sit one out.
If you read through a general guide to diabetes though, know working out with a high isn’t recommended. For one, a workout + high BG is a good recipe for dehydration – your body is already working overtime trying to keep water in while getting sugar out. And two, if you do have ketones, you can really push yourself over the edge by working out when you don’t have cells with ready energy to get you through it. Your body will burn proteins and fat and kick up your ketones more.
The thing is, most of my highs are food induced, which for me doesn’t usually produce ketones. And I tend to look at workouts as an opportunity to bring down a high blood sugar instead of a risk for further damage. But could this outlook get me into trouble? I’ve not had a problem with it ever that I can recall, but I also know it goes against HCP recommendations.
Do all of you have a high number that you won’t workout at? Or do you always push through?
