My husband is scheduled to have lapband at the end of this month. he has been considering surgery for 3 years, and researched his options extensively. It was not hard to see how the lapband was a far, far less risky option than gastric bypass.
Still, it is NOT the easy way out. He will have to make a lot of changes. the thing with him is that he is at a point where exercise is pretty much impossible, and he is approaching this as a tool to help him get to a point where exercise is possible.
I have heard that there are places that file people through with little support, so be careful who you use. The doctor he is using has a full program you go through. he's done 6 months of prep, including nutritional counseling, classes at the center, a psych eval, meeting once a month with our family doc., meeting with the surgeon. After surgery, he will be required to go a support group meeting once a month and have regular follow-ups. Any amount of support less than this, and I would be suspicious of the surgeon.
my best friend had lap band 4 years ago, and has had a mixed experience. She developed a clot during surgery and almost died from that. once she recovered from that, she went on to lose 100 pounds in a year. this was including healthier food choices and working out 6 days a week. but then, her port flipped and she lost the restriction, and has gained some weight back. she will have to have the surgery redone. she still recommends this as a viable option, because she realizes that the clot could have happened from any surgery. and they've made changes to the bands themselves and adjusted the procedure slightly so that slippage is not the problem it was a few years ago.
For both her and my husband, the reality is that they are/were already "dying". serious, life-threatening conditions are/were developing, so the risk of surgery seemed tolerable in comparison.
whether you choose surgery or not, at some point you will have to approach the mental, emotional and spiritual causes of your eating disorder. I have battled my weight most of my life as well, and have found this to be an important part of weight loss. I'm not losing weight right now because I'm pregnant, but before the pregnancy I finally found the combination of factors that was working, and I plan on picking back up with those when I'm recovered. I am meeting with a christian counselor and going to celebrate recovery, which is a christian 12-step group. I found that weight lifting was the kind of exercise that was most effective for me, and swimming. I also have PCOS, which meant that hormones were a HUGE factor that had to be resolved. I took fortamet, fish oil, and vitamin D, as recommended by my Ob/Gyn. I also saw an acupuncturist 2x a month and took the medicinal herb blends she gave me. I also followed her dietary recommendations. ALL of this working together resulted in the first weight loss I'd seen in years, and a healthy pregnancy!
So, I know that's a long post, but that's the spectrum of anecdotal experience I have to offer you. I'm proud of you for endeavoring to improve your life, and wish you the best whatever path you choose.
