We all have certain height and weight proportion as per our ethnicity, we as Asian have average height for males ranging from 5.3' to 5.11' and females ranging from 4.9' to 5.7'. Also, our height and body weight depends on various factors like genetics, physical activities pursued since childhood, eating habits, exercise, hereditary familial body features. Hence, all these are naturally occurring bodily changes which should not be intervened with any surgeries as it is just a reconstructive surgery or surgery performed for aesthetic or cosmetic purposes which may further lead to many side effects in previously healthy body. Well that's just my opinion, you can very well consult any orthropedic or cosmetic reconstructive surgeon/doctor for further consultation.
