Hello Jade,

I can tell you my experience is similar. I play racquetball rather well and was concerned about the possibilities of getting low blood sugars, and needing to take a snack along. I start feeling "shakey" after the third match. Pulled out my meter and it ran 250! Alarmed I did a retake and it came to 255. Within the hour of returning home it got back to around 110. I called my endocrinologist and he was unconcerned as long as the numbers when down following exercise.

I have since asked other "experts" and basically they say that your liver is pumping out the glucose to enable the exercise you are demanding. And it is pumping more than needed and more than your own insulin can handle.

I also run and lift weights, but for me it is the intensity of racquetball, male competitiveness, and short breaks between games that puts my numbers so high. I don't feel great about it, but have learned to leave the meter at home! I have also cut my play time down to an hour max.

Do others have insights on this? Is this your experience with exercise?
