Thanks for query,
normally the epiphysis
fuses with metaphysis of long bones around the age of 18 years so there are enough chances of your increase in height.
Height of an individual depend upon the genetic factor ,hormonal
level any organic disease or any deficiency of clacium absorption mechanism.
you should take enough calcium rich diet,do more cycling,jumping with strings will help to improve your health.
Unless you have any disease or hormonal imbalance there is no medicine to increase your height.
don't eat more noodles as it is a junk food gives you more obesity.
