Large bone age does not necessarily mean that you will not grow taller. If the bone age is between 2 years old, it will not affect the height of the child. However, if the epiphysis closes prematurely, it may affect the later bone development. Bone age is more likely to fluctuate up and down until the child is 5 years old. In children within 2 years of age, the growth rate is faster, and the average height can reach 5cm a year, within this stage, if the bone age is not more than 2 years old, it will not affect the height. However, it can reflect that the child’s growth and development is slightly faster than normal. Parents need to accompany the child for regular checkups and can do some physical exercise to enable the child to return to the normal level of development. A major factor in determining whether a child can grow taller is to observe whether the epiphysis is already closed, and if the epiphysis is already closed, the probability of growing taller is relatively small. The time of epiphyseal closure is generally 17-22 years old for men and relatively early for women, generally around 17 years old. If a child’s epiphysis closes early within this closing range, the bones may stop redeveloping, resulting in no more height change and the child may not grow taller. In order to prevent early epiphyseal closure, it is recommended that children take more calcium supplements, do some stretching activities and get enough sleep to promote their growth and development to a normal level.
