Ive not had a gastric bybass , but my mother has. She had one when she was around 14 stone (sorry , don't know what that is in pounds). That was the leightest weight they'd every done one on in the hospital she was at. At first she got loads of leaflets from the doctor..read through them and discussed it with family. It is quite a complicated procedure , and can be quite risky. She discussed it with us then decided to go ahead with it. She had it pretty much striaght after she decided to get it done, she was in hospital for about 2 weeks afterwards. When she got home after the operation its like being a baby again , your digestive system needs to get used to food. She had to eat baby food for quite a few weeks , then , like babies , she moved on to stuff like bananas and beans. Everything went well , she was losing loads of weight. Then , after about 8 months...she was 6 stone. Basically VERY underweight..and she kept losing weight. The doctor that did the operation refused to help unless she paid ridiculas money. She then phoned some-one else and they told her that it will even out in the end. After a while ..she went to a nice 9 and a half stone. Perfect. She doesn't regret having it done..but,,, There are some down sides to... If you eat something with to much fat in you'll be sick--alot..for like an hour. My mum used to have to lie outside the bathroom with a fan. But once you get used the food you can and can't eat..your fine. My mum used to just eats junk but she's used to healthy stuff now because of the risk of being ill. Note though , my mum only lost loadsss of weight because she wasn't that big when she had the operation. If you go through with it I hope you are happy with the results. Love Steph.
