How can i stop growing ?

When you are: Finished with puberty, your bones will stop growing, and that will be the end of it. Once your bones close the epiphyseal plates, you won't get any taller, no matter what you do. You'll have to wait until nature has finished it's work on your individual canvas. You are a one of a kind piece of art. If you are worried that there is something wrong, have your parents take you to an endocrinologist.

Learn to love: yourself including your height. There is no safe way to intervene with Mother Nature on this one. Take care.
