Many parents believe that because children nowadays are well nourished, it is normal for them to develop earlier and be taller. However, they do not realize that these phenomena may not be a good thing. If the early growth is caused by precocious puberty, it will affect the development of height, and ultimately cause the short stature of adults. Normal Sexual Development Under normal circumstances, girls are usually more than ten years old before the development of secondary sexual characteristics, such as breast development, pubic hair growth, menstruation, etc. Boys will be twelve or thirteen years old when the development of secondary sexual characteristics begins. In boys, secondary sexual characteristics such as testicular development and beard growth begin to appear at age 12 or 13. If a girl’s breasts develop before the age of 8 and a boy’s testicles develop before the age of 9, this is considered precocious puberty. What are the dangers of precocious puberty? Precocious puberty can cause both psychological and physical harm to children. The child may have low self-esteem, fear and anxiety because he or she is different from the surrounding peers in terms of body size and appearance. Early menstruation in girls often affects their normal life and study. Boys may develop early love tendency and premature sexual behavior. As children with precocious puberty are often accompanied by accelerated bone growth, although they temporarily seem to grow faster than others, they use up the part that they have to grow later on. The more they grow ahead of time, the faster their height growth stops, and they will be shorter than others when they grow up. How to treat precocious puberty? Pseudo precocious puberty does not require special treatment after diagnosis, and the symptoms will gradually subside after exposure is stopped for a period of time. Gonadotropin-releasing hormone analog treatment is recommended for true precocious puberty, which can prevent the development of secondary sexual characteristics, slow down the progression of bone age and improve lifelong height. However, growth deceleration may occur during the application of this drug treatment, generally after half a year of treatment, the growth rate will fall back to about 5 cm/year. In recent years, gonadotropin-releasing hormone analogs and genetically recombinant human growth hormone have been used in the international arena as a combination of drugs to overcome the problem of growth deceleration. The vast majority of precocious puberty can be cured, but early detection and timely treatment are very important. As long as early detection and timely treatment, patients with precocious puberty can obtain normal psychological status and desired adult height, and the earlier the treatment, the better the result.
