Borrowing money for surgery

Somebody I know is going to have a Laser Liposuction. I understand her because she really needs one but, I don’t understand where she got the money from, because as far as I know, the laser liposuction cost is high. If I had weight problem, I am sure that the Laser Liposuction cost wouldn’t matter. She probably borrowed money to cover the Laser Liposuction cost. I am proud of her because she does everything that makes her happy.
