As someone who had a private gastric bypass 10 years ago I'm positive she would struggle/never do it. If its NHS then she will have to complete a weight target loosing on her own first and have psychological assessments prior to an application for funding then it needs to be approved. If she's going private then she needs £12,500+. After the difficult/honeymoon first year post surgery when weight can drop off then she will need to be all over her eating for life. Because the stomach can stretch and many regain some or all of their weight. 10 years on I battle all the time and struggle to remain at 12st/13st at most and 11stone if I can. I however wonder if she is going to have her Dad to live with them?But weight loss surgery only works if you’re willing to work for it. Her eating habits are disgusting and no amount of surgery will help with that if she doesn’t change . She hasn’t even tried to lose weight for longer than a week. She should join SW and it’ll drop off her all whilst eating healthy too
