plastic surgery

Though these surgeries include the word 'plastic' it has nothing to do with the synthetic polymer material. This is a surgery involving correction or reconstruction, in either form or function or both.This is used for medical(reconstructive) or cosmetic reasons.
Reconstructive surgeries are performed to improve function and to approximate normal appearance. These are used in patients with burns, traumatic injuries, birth abnormalities, and lot more.
cosmetic surgeries are performed to alter a part of body that person is not satisfied with; enhancement of appearance. Breast implants, fat removal,firming and reshaping the abdomen, redoing nose, lips are the most popular cosmetic surgeries nowadays.
People do these surgeries mostly because they are not comfortable with there own appearance.They see these surgeries as a way to fit in or a way to stand out from a crowd.
I think doing a plastic surgery, reconstructive or cosmetic is totally acceptable. Because it will affect there self esteem in a good way and they will valu themselves.but I don't think plastic surgery is the first option for loose your weight or getting beautiful or anything.because an effective plastic surgery will be really expensive. And it carries a great risk and also whole lot of emotional stress.
everything has its own pros and cons, so I think its upto them to decide what they really want and whats best for them.
