I am only 168 cm height i very sad about i am very short compared to all my friends is there is any way i can be taller i am 17 years old ???

Maybe: Most males finish their linear growth by 17, but some will continue into their early 20's. An x-ray of your wrist and hand could confirm open growth centers that predict more growth. The expected final male height is the average of their parents height plus 2.5 inches. A balanced diet, proper sleep and exercise will support normal growth. No special exe3rcise or diet will make you taller.
