Human growth and development is a continuous process that lasts from fetal life to adulthood, after which one does not grow any taller. Infants usually use body length to represent height because they cannot stand. Human growth and development proceeds in a certain proportion and in a certain order, in addition to horizontal growth, there is also vertical growth, and it should be carried out in accordance with the law of growth and development from top to bottom and from near to far. Therefore, to predict the phenomenon of growing taller, you can observe the changes in weight, head circumference, chest circumference, and circumference of the limbs to determine whether there is a growth in height. It is also possible to observe the appearance of ossification centers at the ends of the long bones of the limbs through X-ray examination, but radiation is harmful and should be avoided as much as possible.
