Medical research shows that the decisive factor controlling height in the process of human growth is the endogenous growth hormone secreted by the pituitary gland, which directly promotes the differentiation and proliferation of the epiphyseal cartilage plate, thus making the body grow taller and taller, and finally the epiphysis is completely ossified, completing the process of height growth. Generally speaking, after the age of 16 for females and 18 for males, the epiphysis gradually closes and height growth gradually stops. It is because it takes nearly 20 years for a person to grow taller. Therefore, parents often mistakenly believe that the growth of children first and later; or mistakenly believe that the growth of children by genetic influence, parents are not high children are bound to be high; or mistakenly believe that the growth of children is the body’s natural height, not subject to the interference of external factors, and sit and wait for the growth of children. Knowing that after the best period for children to grow, it seems that there is no hope, or job hunting and employment is hindered, only to remember to ask the hospital to grow taller, it is often too late. Therefore, parents are reminded to monitor their child’s growth rate regularly every year. If you find that your child’s growth rate is less than 4 centimeters per year, you should go to the hospital and let the doctor help you evaluate whether your child is short.
