My height is very small according to my age. what can i do to speed up my height growth ?

Doctor can measure: If over 16 years old and had no growth in the past year, then growth has finished. Most people reach their maximum height in their late teens. Without nutritional problems or chronic childhood illnesses, height is largely based on genetics and parental heights. Aside from eating right, exercising, sleeping well, and being happy, there's not much a person nor his doctor can do to increase height.
