In order for children to grow taller, it is important to prevent precocious puberty from occurring. A direct consequence of precocious puberty is the early maturation of the bone age. In medical science, the age of the bones is monitored to determine whether the child is precocious. The child with precocious puberty is often taller than children of the same age, but the growth period must have ended early, and when parents find that the child is not growing, the child’s bone age has matured, and it is too late to increase height. Therefore, it is best to check the bone age of the child once every six months to a year, once found that the bone age growth is too fast, we need to find the cause. Now, we have better drugs to control precocious puberty, but the problem is that precocious puberty is usually discovered by parents very late, when the child’s bone age is basically mature, it is already very difficult to grow taller. Therefore, once precocious puberty in children is confirmed through bone age monitoring, medical intervention must be carried out in time to delay the maturation of bone age and ensure the child continues to grow.
