I am jealous!!!!!!! Can I come too??
I have been skiing as a T1, and didn't notice any difference with absorption. The thing I did notice was that all that exercise meant that I did need extra carbs. The other thing to make sure is that lots of extra sugar, glucose tabs, chocolate (anything high carb and easy to eat in gloves is put in all the pocets of her ski jacket. On my first day skiing, we managed to miss the last lift and had to ski home in the dark. I was very glad of all the extra stores of food I had in my pockets. I do have to say that this was many years ago, before carb counting...so it may not be as important, but don't rely on anybody else to look after her "supplies", she needs to have them to hand. Other than that, hope she has a great time! It is good to see that she lives her life with diabetes, and doesn't let it stop her.
