My daughter’s 5.5-year-old central precocious puberty may not grow taller, but through active treatment, it can also play a role in promoting height growth. Central precocious puberty, also called gonadotropin-dependent precocious puberty, is a condition in which the hypothalamus increases the secretion and release of gonadotropin-releasing hormone (GHRH) in advance, leading to the development of secondary sexual characteristics in the affected child. Due to the elevation of GHRH, the affected child will experience rapid growth in height and body weight, which will lead to an increase in the age of the bones, and this will affect the child’s final height, resulting in the child’s failure to grow taller. Central precocious puberty, if timely intervention, can also promote the growth of height, can be used under the guidance of the doctor treprostinil and leuprolide treatment, these drugs can inhibit the gonadal axis, delay the development of the secondary sexual characteristics, some of the children with regular treatment, the final height of the child can be achieved more satisfactory results. The treatment of precocious puberty is a slow process, in the course of treatment should be followed up regularly, usually need to communicate with the child to avoid psychological problems.
