Patient's question:
The child is now 8 and a half years old and has always been lean. This summer vacation, it's not known whether it's because of the high exercise volume from learning to swim, but they have finally reached 50 jin (about 25 kilograms) and are 1.38 meters tall.Doctor's answer:
Hello, it is due to developmental reasons. If girls exhibit signs of sexual development before the age of 8 to 8.5, or boys before the age of 10, it is considered precocious puberty. There are many factors that can affect children's development, primarily race, genetics, climate, nutrition, and diseases, which also play a significant role. Therefore, there is a large individual variation in children's development. With economic development, puberty is also continuously advancing. Of course, it is still best to check the endocrine system.
