Diabetes is a ridiculous creature. It requires a level of balance and work that most people just don’t seem to understand. The problem is, something that works one day may not work out quite so well the next. One needs to find a delicate balance between food, insulin and exercise to maintain some semblance of good health.
When I was first diagnosed with Type 1 Diabetes in 1982, there were a lot of things lacking from my routine to make it a proper one. Carb counting wasn’t a thing (at least not for me) so insulin dosages were something of a guessing game. My glucometer (blood testing machine) weighed almost three pounds and it took almost two minutes for a blood sugar reading. I won’t get into the process it entailed, but it was way more complicated than the simple, ten-second finger poke I do today. The common belief at the time was that food increased blood sugar and exercise lowered it. Although this is isn’t completely false, it isn’t completely accurate either.
The human body contains some 79 organs (depending on one’s definition of an “organ” and what medical journal you’re reading). Your body has this tendency of trying to make all your internal systems work together in harmony. That being the case, your Endocrine System (the internal system that contains the Pancreas) will work to compensate for some of the things your Pancreas lacks. For more information on these individual systems, check out Wikipedia (en.wikipedia.org/wiki/List_of_organs_of_the_human_body)
Although I usually only work for about sixty minutes, on average, sometimes my workouts have gone for as long as two hours. When you perform intense, physically-draining exercise, your body generates adrenaline. Adrenaline is wonderful stuff. It relieves pain and alleviates some of the stressors on the body during critical moments. It also has one other unexpected side effect: in increases blood sugar. So if you’re having a total kick-ass workout and you’re having a blast and you feel that “runner’s high”, chances are that your blood sugar will rise, not drop (despite the physical exertion). If you’re doing something consistent (like running, cycling or elliptical) you’ll burn calories and lower your blood sugar. I don’t want to say that cardio in general is boring, but it doesn’t produce the adrenaline kick that high intensity workouts do.
The primary issue with this is that if one tests blood sugar levels right after a high intensity workout and takes an insulin dosage to adjust for the high, blood sugars will bottom out once the adrenaline dies out and the insulin kicks in.
There’s no magic formula to circumvent all of this. If you have Diabetes, all you can do is plan and adjust! WebMD has a good page relating to this. It can be found at https://www.webmd.com/healthy-aging/features/exercise-lower-blood-sugar#2
Things have changed considerably for me since 1982. My blood sugar is tested via wireless sensor attached to my bicep. My insulin is delivered through an insulin pump. The benefit of all these gadgets is that I’m down to one needle every three days, at most, as opposed to over a dozen needles, including blood testing and insulin injections. I’ve been taught how to carb count and calculate appropriate insulin dosages based on my specific metabolism.
Be consistent, check with your doctor before starting any major fitness regiment but stick with it. Diabetes often causes a sort of lethargy or feeling of laziness. This doesn’t mean that you can’t push beyond this feeling and experience a solid burn through your workout. Diabetes doesn’t prevent good fitness; it is simply another obstacle for a strong fitness enthusiast to work through.
