Exercise and BG are strange bedfellows :confused: ....

I've noticed that mild exercise - like ~5km jog at easy pace - has almost no effect on my BG.

But a 30 minute high intensity workout on a gym stationary bike will spike me by about 1.5mmol/L (just found this out over the last few days, still trying to get a handle on it. . . )

And endurance exercise - like 60km+ cycle ride will definitely result in a hypo unless I plan my insulin injections & what/when I eat very carefully :eek:

Fun, isn't it!!:D

It's probably described in the other threads, but it's the result of a natural process of the body. When you start on anaerobic exercise (using your muscles), adrenaline hormone levels rise triggering the release of glucose from internal glucagon stores. If I recall correctly, glucose is released/produced up the 8 times higher than normal, while uptake does also increase but only about half of that rate.

Result - excess energy in the bloodstream, higher insulin requirements and not enough insulin - leading to higher BGs. Extra insulin than normal may be needed to cater for this effect.

Of course a mix or predominantly aerobic exercise can have different effects on the BG, commonly leading the other way of having too much insulin in the system (if not modified, by a pump temp basal for example), so the nature of the exercise and your particular reactions to various types, mixes, and periods of exercise, have to be observed and considered closely.
