Truthfully, I think that if you're willing to pay enough, they can fix anything surgically, even the wrinkled thighs that would result from the procedure. However, it can have other complications. This is SURGERY... and it's just not worth it. People should only have surgery if it's something they really need, medically, to save their life. Your mother can exercise, she could get a personal trainer, she could walk ever day, she could swim. I think that you should help her to find other options, because they do exist.
