Spiking after exercise?

[Jeff in Vermont]

Hi all

Have an odd question.

The last 2 times I've gone to Physical Therapy, I've gotton a spike at night much higher then what I get normally.

Does any one know if there is a connection or is this just a coincidence?

I have only read a little on the subject and others could probably explain it in greater detail than I, but as I understand it, a spike later in the day after exercise is not uncommon.

My BS spikes a little about 3 hours post, but not that bad.

I brought this up to my CDE and she said that spiking after exercise usually only occurs when your blood sugar is too high to begin with. I understand that you aren't supposed to exercise when your blood sugars are over a certain level or especially if you are spilling ketones. However, I don't know if you start with adequate levels, if the exercise is very strenuous or intense if it can cause spiking. I think I have actually experienced this myself too I'd be interested in hearing what others have experienced.

Your body has a process called gluconeogenesis (glucose from nowhere, basically) where the liver will react to exercise by releasing glucose into the bloodstream to help your muscles needs for energy during intense exercise. You didn't say, but I bet you were doing anaerobic (ie, weightlifting) exercises for PT, right? If you were, that's why your sugars spiked. We seem to have some evidence here that if you are prone to having a spike due to exercise, it is because of intense "burning muscle" kind of exercise. ON the flip side, if you do lower intensity, less strenuous work like walking or light bike riding, sugars seem to drop, and be lower for extended amounts of time afterwards.

I don't seem to suffer from gluconeogenesis, which would explain why I do not look like Arnold, yet. So I am beginning to inject glucose after workouts...

I know from experience, that when I was working alot and walking alot, I could eat anything I wanted.

The exercise was burning up alot of calories.

I always got into trouble when I stopped doing alot of work and walking and didn't adjust my eating to compensate.

That's why I always gained weight in the winter when things were slow.

Now I'll need to watch things till I finish with my PT more carefull.

Hopefully, I'll be able to start a walking program in a month and get back to some work (this sitting around is getting boring!!!).

Too much to do and I can't afford to pay someone to do my work.

Great, thanks again for the help.
