In most cases, children with precocious puberty will end up being shorter without any treatment, because after precocious puberty occurs, pre-menstruation, premature breast development and significantly earlier bone age will occur. The epiphysis will close early when the child’s bone age is significantly early, and when the epiphysis is closed, the bones will not be able to grow again, and thus the increase in stature will stop. Therefore, after the onset of precocious puberty in children, it is important to intervene in the treatment, such as the application of Daphylline, so as to slow down the process of sexual development and gain valuable time for the growth of children’s height.
