Thanks for your question on Healthcare Magic.
I can understand your concern.
Sorry to say say but after the age of 21 years, height can not be increase.
There is growth plate at the end of each long bone. Between the age of 18-21 years, this growth plate fuses with main bone. So after the age of 21 years, further growth of bone is not possible, so increase in height is also not possible.
In your case, you should try
weight loss, so that you look tall. So follow strict dieting and exercise schedule with guidance of dietician and physiotherapist.
Don't worry, once you loose weight, you will look tall.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
