I can’t say I’ve ever heard of this in my 32 years of T1, but hey wouldn’t that be nice? Honestly, I don’t think many kids/teenagers with T! are well controlled due to hormone shifts, growing, and generally just trying to be a kid. I know I certainly wasn’t, for reasons both in and out of my control. I’ve always noticed that the language from research studies says that good control can prevent OR delay complications–meaning that even with good control, you MAY only be delaying complications. Not that everyone is doomed to complications, but honestly you just have to do your best and hope for the best.
