What is dwarfism? The standard deviation method and the height percentile method are currently used clinically to determine short stature. In layman’s terms, short children who are in the top three in their class need to be taken seriously, have their height measured regularly, and go to the hospital for consultation in a timely manner. The incidence of dwarfism has increased in recent years and has attracted the attention of all sectors of society. The incidence of dwarfism in the Wuhan area is 3.25%. There are many problems associated with short stature. Compared with normal children, although their IQ is within the normal range, they have psychological personality traits of introversion and emotional instability; behaviorally there is poor interaction and social withdrawal. In addition, the size deficiency also directly affects their schooling, employment and marriage. The age of 4 is the cut-off point for determining short stature in children. As long as early treatment is given before epiphysis closure, there is hope that children with short stature can reach normal height. Therefore, parents should keep track of their children’s basic growth pattern and record their height in detail every year. If you find that your child grows slower than his or her peers during the growth spurt, not even 4 cm a year, then you should be highly alert. Early intervention is important The final height of a person is influenced by genetics, birth height, nutrition, hormones, environment, and disease. Among the many factors, growth hormone plays a decisive role in the whole growth process. If growth hormone deficiency is diagnosed, growth hormone replacement therapy is needed and should be based on the principles of early, timely, adequate and long-term. Studies have shown that the younger the child is, the more active the proliferation and differentiation of the cartilage layer of the epiphysis, and the more sensitive the child is to treatment; moreover, the younger the child is, the lighter the child’s weight is, and the smaller the dose of medication is. Therefore, it is important not to wait until the age of 15-18 for treatment, when the epiphysis is close to closing and the growth potential is small, and it is no longer possible to achieve the ideal height.
