It is my understanding that children who are untreated with CAH grow faster and are large children, at first. Their bone growth is too rapid and the growth is stopped shortbecause the bones have fused and no more growth can occur and they are very short adults. Anyone, please correct me if I am wrong. There may be people who grow just the opposite, I've never heard of that happening but it sounds like you are in good hands. Good luck and let us know!
