Children in adolescence, the speed of bone growth is relatively fast. If it is found that the child's height growth is not obvious within one year, or there is no growth, and there are more and more muscles, there is a feeling of muscle tightness. If the child has the above symptoms, it may be a sign that the boy will stop growing taller and will not grow taller again. You can take the child to the hospital to take an X-ray to see if the epiphysis is closed. If the epiphysis is closed, it means that the child has stopped. Under normal circumstances, boys around the age of 20, the bones began to close to healing, and the growth rate of height slowed down.
