You can do whatever you choose to do. I have had Type 1 for 50 years. That is not a typo. Fifty. I am happy to say, that over that time, I have played: football, basketball, volleyball, baseball, softball, punchball,stickball, hockey, tennis, horseback riding, trampoline, jumped horses, swimming, skiing, running, bicycling, canoeing, rowing, waterskiing, motorcycling, road racing motorcycles,motocross, quad riding, ice skating, roller skating, and I am sure I have forgotten a few. There is a wealth of knowledge on this website on the ‘how to’ of it all, and wonderful support. There is also a book called ," Diabetic Athlete’s Handbook ", by Sheri R. Colberg, PhD, and I think I got my copy by Googling the title. It is a fountain of information on the relationship between specific types of exercise and the ability to regulate your needs. All can say is every time I get out there and do something athletic, my sense of empowerment is great. There is nothing like that feeling in the world. Yes, sometimes, I feel a little scared about whether I will go too high or too low, blood sugar wise, but I cannot let that stop me from doing what I do. I always tell the story of my early years, and back in the dark ages, we had no blood sugar testing at home. My treating doctor always urged my parents to let me do as many things as possible athletically, because it was the way to keep blood sugar in check, since we did not have a measurement to fine tune our insulin needs. So , to this day, I still believe in the theory. Now , we can fine tune in a way I never dreamed of. Enjoy, and go for it.
