When will girls grow taller? When will girls grow taller?

In adolescence, due to the interaction of hormone stimulation, congenital factors and acquired environmental factors, the growth rate of bones is obviously accelerated and the body grows taller. The maximum growth rate of female students begins at the age of 12 ~ 14 (mostly around the first menstruation, the height grows fastest); Boys' puberty will not suddenly increase until two years later. Most women grow to 19 years old and stop growing at the age of 23 at most; Men have to grow up to 23 years old, and some can grow up to 26 years old. The height of the body is a foregone conclusion. The bones of lower limbs grow rapidly in adolescence and become the key factor to determine their height, but their growth is not long; The growth rate of spine is far less than that of lower limb bone, but its growth is more lasting than that of lower limb bone. Therefore, a person's height depends mainly on the lower body before the age of seventeen or eighteen, and it depends entirely on the upper body after the age of seventeen or eighteen.
