Whether it’s elementary or middle school, classes involve seating and standing in line, especially for freshmen. Of course, tall and short are relative, and the final height of human body is inseparable from genetic, environmental, nutritional, exercise, sleep, and psychosocial factors, but if your child still sits in the first three rows of the class because of short height after a holiday, and the annual growth rate is less than 4 cm, and the gap with children of the same age is gradually widening, you should pay more attention to it and take your child to the hospital for examination as early as possible. Clinical medicine uses the standard deviation method and height percentile method to determine short stature: the child’s height is lower than the 3rd percentile or two standard deviations (i.e., more than 5-10 cm lower than the average height) of the normal height standard for children of the same age, sex, region, and ethnicity. Dwarfism is a disease Taking health care products to “help growth” is often the first choice of parents of children with dwarfism, but the huge economic investment in exchange for a painful lesson, “health care products are ineffective in increasing height!” The root of dwarfism is a disease, and it is the right way to treat the cause after identifying it. According to a survey, 70% of parents in China do not know that their children’s short stature may be caused by diseases. There are various causes of dwarfism, including endocrine diseases, familial dwarfism, somatic growth and developmental delay, chromosomal abnormalities, etc. Among them, some children suffer from growth hormone deficiency, which is a growth disorder and short stature caused by insufficient secretion of growth hormone, and used to be called “pituitary dwarfism”. For these children, growth hormone injections are an effective treatment. How to grasp the best time to treat dwarfism. At the age of 4, the growth hormone and thyroid hormone are basically formed in the body, and the eating and sleeping habits are gradually formed, so we can see whether there is any defect in the figure. It is recommended that parents measure their children’s height every 2 months, and if the growth rate is too slow, it is time to see a doctor. Domestic treatment for dwarfism is received relatively late, with 70% of the age range being between 11 and 16 years old. In contrast, the average age of treatment abroad is 6 years. The older age of initiation of treatment contributes less to adult height, and early treatment can maximize the adult height of the child. Therefore, 4-6 years of age is the ideal age for the diagnosis and treatment of short stature caused by growth hormone deficiency.
