Knowitallstrikesagain: There is jjust so much more to it with weight loss surgery though.
If you have it done privately, you have people speculating on your financial situation; in this climate, a lot of people don't have 10k kicking around in a savings account, and telling people you had private surgery is like basically saying you do. That's what my op cost me, just shy of 10k. And then you get people saying "well, that's just mad, imagine what you could have spent that money on, if only you pulled your finger out and lost it the traditional way".
And on that point, a lot of us who have weight loss surgery HAVE lost it the traditional way, several times. I have. I've lost weight on slimming world, weight watchers, Lighterlife...6 stone I lost with them. Statistically, weight loss surgery is the best option for long term weight loss and weight maintenance. Its the one thing that gives the best possible chance of losing the weight and keeping it off. Obesity surgery patients know how to lose weight, generally; they struggle particularly with keeping it off long term, and there is a limit to how many times you should lose and gain the same few stones. Its bad for your body.
And then if you had it done on the NHS, you are an evil selfish fatso for sapping resources that could have saved someone from breast cancer (which is not actually how it works, and in fact you may well have saved YOURSELF from breast cancer for less £££ than it would have cost to cure you if you hadn't had surgery and had gone on to get it) and all that malarky. If its public funds, people think they have a say in it, if its private funds, people speculate...
Its so much more than simply weight loss and how you did it.
There are the risks of surgery - people will say "I can't believe she risked her life when she had children, how selfish" when actually statistically you are far more likely to die from an obesity related illness if you don't have it than to die on the table if you do (which is why the NHS fund it for people with co-morbidities)
I could go on, but the main point I'm trying to make is you will never please everybody with something like this, so you may as well please yourself.
