I also read this story and I think the whole thing can be summed up in the last paragraph where her Mum says if she didn’t have it she would have died. Personally, I expect my skin to look worse than that when I have lost my weight (if I lose, I still think I will be the one person that defines medical history and not lose anything lol). I know I will have excess skin and it is a very small price to pay for the benefits of weight loss, health etc.
Also, I wonder it she had a psychological assessment before hand. Surely part of the assessment is to monitor the patients expectations about what life will be like post surgery.
It seems a shame that she regrets her surgery when obviously it has been very successful. I suspect if she was older and wiser she would view things differently.
