I’m guessing that adding an oral med Rx for one day might be tough.
Depends on the numbers. Exercise highs can be tough because they are sticky, even with insulin. But, if its consistently high and not oscillating a lot, then a few units of over the counter NPH on Frisbee days might just do the trick. Its a fast, simple solution if the user is acquainted with insulin already. An early morning shot of 5 units might do it. I dont know.
I sometimes have to dose 12 units of rapid prior to cross county skiing/downhill skiing in the morning. (I do not recommend that he do that…thats just me).
His liver is pumping glucagon/glycogen/sugar. A med might be better for treating that, in general. But, at the same time, that energy output is what makes you perform well, so I dont know if it helps performance to prevent it. Its possible that its better to treat it with insulin. Its interesting.
I find that my best performance is often accompanied by high BG. Thats my body wanting to work for it and rising to the challenge. That energy output is good. But, if I go too high, then I will feel like crap. I can’t always predict that behavior reliably. So, I tend to treat with short term insulin. Sometimes the interval of oscillation is so short that it becomes a complete crap shoot. However, sometimes I see a very predictable, day after day pattern of it steadily rising (maybe 300 points an hour…which makes basal a better fit UNTIL glycogen is depleted). At some point your body WILL stop outputting sugar. Then, you are at risk of severe and rapid lows. It might take 24 hours to reach that point, or a couple days. Hard to say.
I guess i would recommend actually playing the course a week prior to competition and try a treatment. That might give the best chance of success. A lot depends on ones ability to predict the pattern. If its super predictable, I would treat with a little long term. If things are unpredictable, then you might not have any choice other that treat with a few tiny rapid insulin shots (less preferable).
