Old people say there are “early growth, late growth”, in fact, a person’s youth development should be a relatively fixed age, if premature development, in the sex hormones involved, the bone age will be early healing, although now look long fast, but the child will soon not grow. The late growth is only a delayed individual puberty, usually with a family history, but no one can guarantee that by the age of 23 whether or not they can still flee again. If the child is found to be short after puberty, it is too late to treat the child because the best time for growth has been missed. Some parents think that their children are short, but they are only 10 years old, they are still young, they do not have pubertal development, they can still grow later. It is true that children have to have a rapid growth period during puberty, but everyone enters puberty with a different height, if the child is of normal height, the rapid growth through puberty is ideal for the final height. But if the child is much shorter than the same age, even if the same growth to puberty, but still can not reach the ideal height. So we should not believe in the old idea of “early growth, late growth, twenty-three scampering a scamper, let the child grow naturally, so that the child lost the last opportunity to grow. Parents should look at their child’s growth potential through scientific evaluation, such as secondary sex characteristics, bone age, family history, etc., and intervene as early as possible to prevent regret. During childhood, if you find that your child’s height is significantly lower than that of children of the same age, or the growth rate is less than 4 cm per year, it means that there may be a height problem, and you should go to a specialist hospital as soon as possible to check and find out the cause. There are many causes of short stature in children, such as growth hormone deficiency, idiopathic dwarfism, small for gestational age, Turner syndrome, delayed institutional puberty, etc. During the summer, parents should pay attention to their children’s height, discover it as early as possible and intervene to improve it!
