I. “What should I do about my child’s early development, is it some kind of disease?” After the specialized examination, it was found that Lin Yan’s bone age was two and a half years early, her sex hormone level was elevated and her gonads were enlarged, which belonged to idiopathic central precocious puberty. Precocious puberty refers to the early appearance of secondary sexual characteristics and is divided into central and peripheral, also known as true and false. There are many diseases such as intracranial tumors, hypothyroidism, ovarian tumors, etc. that can cause precocious puberty, so if you find that your child has early sexual signs, you need to consult a doctor first. The doctor will be able to distinguish the type and determine the cause of the problem by combining the medical history, specialized physical examination, bone age development index, hypothalamic-pituitary-gonadal axis function index and other information. Second, “So my daughter is precocious, what is the danger to her?” The appearance of secondary sexual characteristics means that sexual development has begun, and sexual development and bone development are linked, so once sexual development begins, bone growth begins to accelerate, and the older the bone age is, the less room for growth. In addition, premature breast development and even the onset of menstruation can be a psychological shock to the affected children and bring social problems. Third, “It turns out that precocious puberty will lead to short stature instead, so is there any way to save it? Is it necessary to treat precocious puberty? Is it possible to apply traditional Chinese medicine?” For children with precocious puberty caused by organic diseases, treatment of the original disease is the main concern; for children without original disease, if the disease is long and serious, GnRH agonist injection treatment can be used; if the disease is short and light, the treatment with Chinese medicine alone can achieve satisfactory therapeutic effect. If the child with precocious puberty has advanced bone age and height simultaneously and the adult height prediction is still ideal, it can be treated without medication and regular monitoring is the main focus. If precocious puberty is detected early, it is entirely possible to control it, but if it is delayed too long, or if the child is older, or if the sexual development is nearly mature, the best time for treatment is lost and the effect is poor. In the early stage of precocious puberty, regardless of whether it is central or peripheral, traditional Chinese medicine can be used, which has various effects. Firstly, it can effectively control the development, so that the hard nodes of breasts can be reduced or disappeared, the vulvar discharge can be reduced or disappeared, and the growth of bones can be slowed down, so as to win time for growing taller; secondly, it can improve the appetite, so as to win the material basis for growing taller; thirdly, it can improve sleep, so as to facilitate the secretion of growth hormone, so as to win power for growing taller. When the child reaches the age of normal development, he will be switched to the development-promoting Chinese medicine to seize the last chance to grow taller. After the doctor’s analysis, he thinks that Lin Yan is already in the middle and late stage, and the best plan is to combine Chinese and Western treatment. Fourth, “What do I need to pay attention to in the treatment of precocious puberty, and can I stop the medicine once the development of sex characteristics is controlled?” During the treatment process, we should follow up on time, usually once a month, to measure the height and sex characteristics of the child, which also has a supervisory effect on the child; from three to six months, we need to re-evaluate the changes in the condition to adjust the treatment plan at the right time. Both Chinese and Western treatments have a course of treatment. Premature discontinuation of medication or missing or under-dosing is a common cause of exacerbation of the child’s condition. Because the development of sexual characteristics is controlled, but the course of treatment is insufficient, the accelerated skeletal growth has not yet been controlled, and the opportunity to grow taller is lost. For peripheral precocious puberty and simple premature breast development, the medication can be discontinued at the discretion of the patient after the condition is relieved by herbal treatment and consolidated for about six months; central precocious puberty is generally maintained until about 10 years old in the early stage, while children in the middle and late stage need to maintain treatment until about 12 years old. Male children generally need to stop treatment until the age of 12 years. Parents should regularly check the size of the second sex characteristics of the child during treatment or after discontinuation of the drug, urge the child to carry out effective vertical exercise, ensure sufficient sleep, enhance reasonable dietary nutrition, eliminate junk food, and pay attention to psychological education. V. “Do boys also have precocious puberty, and can precocious puberty be prevented?” Although the incidence of girls is much higher than that of boys. But because breast development can be detected and treated by parents in time, boys have a relatively insidious onset and organic diseases are more common, so they need more attention. How to prevent precocious puberty? The first is to control the intake of exogenous hormones; the second is to control excessive calorie intake; the third is to control bad mental stimulation; the fourth is to strengthen the observation of children’s life, especially pay attention to the time of breast development of little girls. Precocious puberty itself is not scary, what is scary is that parents lack common sense and miss a good opportunity for treatment. The Department of Pediatrics of Zhejiang Provincial Hospital of Traditional Chinese Medicine has been carrying out research on precocious puberty for many years and has a daily specialist clinic for precocious puberty.
