Whether or not you will still be tall at age 23 is related to whether or not your epiphyses are closed. If the epiphyses have not yet closed, there is a possibility of growing taller. The normal time for epiphyseal healing is 16-17 years old for females and 17-18 years old for males, but some people’s epiphyses close later. 1. The epiphysis has already closed: Epiphyseal healing is directly related to bone age. The epiphysis will directly affect the size and length of the bones, affecting height. If the epiphysis has already closed, the possibility of growing taller is very small. 2. The epiphysis is still not closed: the epiphysis is not closed, the bones can continue to develop, there is still the possibility of growing taller, but also through dietary supplements to eat a reasonable diet, eat more vegetables, as well as the amount of outdoor exercise, appropriate exercise. Of course, avoid strenuous exercise. If you want to see whether you can still grow taller, you can go to the hospital to do a bone age test, take wrist X-ray and knee X-ray to see whether the epiphysis is closed.
