Hi, Thanks for posting in HCM. I understand your concern. Since you are 17 years, you can grow still taller as you have about 2 to 3 years time by the time the growth is complete. Generally, growth of long bones is complete by 20 years. Hence, you may grow another 2 to 3 inches tall and achieve nearly 5 feet 6 inches, which is quite a good height to achieve. You can supplement your growth by eating healthy diet rich in proteins, essential vitamins and minerals. Exercise like skipping and swimming would also help in this process. In case you are still not satisfied about your growth, you can undergo increase in height by 2 to 4 inches by means of surgical procedure on bones of lower limbs called Ilizarov technique . However, it requires good experience of an Orthopedics Surgeon to perform this operation and would take about 6 to 8 months to get the results. Hope the information provided would be useful. All the best.
