Can i still grow taller with the help of specific diet and exercise? 3 cms are enough for me. a week ago i turned 20. i'm a female.

Unlikely to happen: At twenty your growth centers have likely closed and you are unlikely to grow taller.If you want to know for sure an x-ray of your wrist ; hand can be analysed for bone maturity ; tell if the growth centers remain open to new growth.Good nutrition, rest and exercise allow a person to reach their tallest height while the opposite will stunt growth.
