Hi I'm younis I'm 16 year old and my hight is 6.4 how can I stop the the increasing of my hight

Hello, Younis. Thank you for posting.

Once girls start to menstruate, they usually grow about 1 or 2 more inches, reaching their final adult height by about age 14 or 15 years (younger or older depending on when puberty began). Boys tend to show the first physical changes of puberty between the ages of 10 and 16. They tend to grow most quickly between ages 12 and 15. The growth spurt of boys is, on average, about 2 years later than that of girls. By age 16, most boys have stopped growing, but their muscles will continue to develop. I don't know of any way to stop your height growth. If you are concerned, you can speak to your doctor.
