> Does that mean we will have to deal with these hormonal peaks for literally 8 years??

My son started puberty early, a few months after he turned 12. Before that, his control was almost perfect, about 95% time in range. Now it’s been 6 months, and it is still getting worse. He is 135 lbs, 5’8" and has a faint dark smudge above the lip. My first son stopped growing around 16.5, so for us I think about 4-5 years of bad peaks total – but possibly it continues for longer?

What worries me a bit is this curve which I put up a few weeks ago: [What is the average A1c of T1D patients: study](https://forum.fudiabetes.org/t/what-is-the-average-a1c-of-t1d-patients-study/1129)

It shows patients’ A1Cs getting much worse starting around age 10, which matches our experience. But if you look, the curve does not become really normal until after age 25 ☹ However, I suspect that it is more due to lack of discipline for young adults than it is due to peaks.

@drpepper68, when did you stop having significant hormone peaks?
