A 19-year-old boy may still be able to grow taller if his epiphyses have not healed. However, if the ear bone scale has healed, the chances of growing taller may be less. At 19 years of age, during puberty, you will still grow taller, although the growth rate will not be fast. This is because height is influenced by the genetic factors of the parents. It is also related to the exercise and nutritional supply. However, if the epiphysis heals, there may be no growth. You can go to the hospital for an epiphyseal examination to see if the epiphysis has healed. If the examination shows that the epiphysis has not healed, you can adjust your diet by eating more protein-rich foods, such as milk, eggs, etc., and participating in more physical exercise, such as jogging, basketball, badminton, may also promote the body to grow taller. If necessary, you can also take growth-promoting drugs under the guidance of your doctor to help you grow taller.
