Hello Navachaitanya K,
Why do you ask about being taller?
You could always have surgery or wear heels; but, I advise neither. If this is necessary, then, you need to talk to your doctor.
Please be happy with yourself and strive for the best health possible. Like the others have said, being in shape will make you appear taller than you really are.
If you did not know your height, how tall would you be? Please try not to think about the number and go enjoy life.
I am 21 years old and I had this same issue. Fortunately for us there are way’s to increase your height, however you will have to buy some shoe inserts. They are about 10-40$ on ebay or amazon and can increase your height about 2-3 inches. I have been wearing them for about 2 weeks now. I cant even count how many times people have told me that I’ve gotten taller!
Hope this helps!
