The children will have precocious puberty even if the lights in the house are too bright? This statement sounds like a fantasy, but has been confirmed by medical experts: excessive light is one of the important causes of precocious puberty in children, our hospital saw a four-year-old girl with precocious puberty, she is because from childhood to sleep at night with the lights on In addition, long hours of television, computer monitor light may also lead to precocious puberty in children. The expert introduced that melatonin can inhibit the release of pituitary gonadotropin, which can prevent precocious puberty. When people go to sleep at night, the pineal gland will secrete a lot of melatonin. Children who are exposed to too much light can lead to precocious puberty by reducing the secretion of melatonin from the pineal gland. What are the signs of precocious puberty in children? Boys and girls are different. The whole process of sexual development is basically similar to the normal process of puberty, and the breasts start to grow first, which is easy for parents to see, and sometimes not easy for fat children to see. Boys are relatively hidden, why? Boys’ testicles are the first manifestation of testicular enlargement, which is often invisible to parents, and is often discovered only when his voice changes, or when pubic hair comes out and the child tells the parents, or the parents overlook it, for example, some boys also have breast development during puberty, and only when they see the child’s chest do parents notice whether the child is developing. So, children must pay attention when they are around puberty. If you wait for your child’s voice to change before going to the doctor it will be too late. Precocious puberty is more common in girls, and idiopathic precocious puberty occurs in girls about 9 times more than in boys, while precocious puberty in boys is characterized by a higher rate of development of central nervous system abnormalities (such as tumors), and central precocious puberty is clinically characterized by the early appearance of the development of sexual characteristics similar to the normal pubertal development program, but the clinical manifestations vary greatly, and can develop in all age groups before puberty, with symptoms developing at different rates, and some can develop at a In some cases, the development of sexual characteristics can be halted for a period of time after a certain degree of sexual development, while in others, the symptoms may subside and then develop again. During the process of sexual development, both boys and girls experience rapid growth in height and weight and accelerated skeletal maturation, which can lead to early epiphyseal fusion and a shorter height in adulthood despite being taller than children of the same age. After puberty, all children are normal except for their height, which is shorter than the general group. The sexual development process of peripheral precocious puberty is very different from the above-mentioned pattern. In boys with precocious puberty, the size of the testes should be noted. If the testes are >3ml, it suggests central precocious puberty, and if the testes are not enlarged, but masculinity develops progressively, it suggests peripheral precocious puberty, whose androgens may come from the adrenal glands. Those due to intracranial tumors show only precocious puberty during the course of the disease and later on start to see localization signs such as increased cranial pressure and visual field defects, which need to be alerted.
