With summer approaching and midterms and high school exams over, many parents come to the clinic because their children are short. Some of these children are not actually short, but just have a gap in height than the parents expected. However, there are also some children who are really short, but they usually feel that they are growing late, so they are not in a hurry and come to see us only when they are going to high school or college. The first one is Zhang Zhang from Zhangqiu, 17 years old, 150cm, and the other one is Zou from Zibo, 18 years old, 151cm, but after taking a hand bone film, the long bone epiphysis has closed. Therefore, it is important to detect and treat short stature early, and not to wait until puberty, when the potential to increase height is much smaller. It is best for parents to measure their children’s height every six months or a year and record it. Once they find that their children have height problems or slow growth rate, they should seek medical advice in time so as not to miss the best time for treatment, which may cause lifelong regrets.
