If your bmi is over 30 in uk you can go private, it really is no ones business if you decide to do it or not, at the end of the day is a decision only you can make and take in consideration perhaps what your family has to say. My experience I believe I was 32 bmi, I'm only 5ft1 and always struggled with my weight, I was 14st4 when I decided to have the surgery as I really tried everything in my power to do loose the weight since I was 10. Sometimes we just need that extra push and the band done that for me as been a very hard process but very rewarding I went from size uk 18 to 8!!!!! From 14st4 to 8st13!!! I am glad to say I have no extra skin and really happy to have done the surgery when I was 21! Not even one year on and I already lost all the weight and I am now with a healthy bmi!! Good luck to you all, and do what feels right but remember is a tool not a miracle, you gotta really work on your nutrition, for 3 months I did not touch chocolate or anything bad at all!! Will power!!!
