I think when you are younger you are bound to be more concerned about such matters as being left with loose, saggy skin as 'fitting in' is so much more important to you when you are young! I remember all so vividly feeling 'trapped' in my ugly fat body, feeling miserable and left out whilst all my slim friends were wearing skimpy, trendy clothes and I longed to be like them so It is understandable that when a young person loses a lot of weight they would feel most unhappy if they were left still unable to wear all those sexy, skimpy little clothes due to unsightly, surplus skin! Having 2 darling daughters myself I can well understand why this would be a major problem for any youngster, girls especially and I just hope the doctors and surgeons would be sympathetic in such a case and to not help would be cruel and unkind especially after they have worked so hard to change their life!
