I wanted to go with the Lap Band it at first because it's less invasive ... BUT it doesn't always work so well ... AND .... it's a hassle.
My doctor does 2 - 3 'revison' surgerys a week. These are surgeries to undo the lap band and take the RNY or another WLS.
The RNY is the 'gold standard' of WLS and ... it works 'for sure' - not for 'maybe'.
Read
www.lapbandtalk.com and see the complaints as compared to the complaints this forum or
http://www.obesityhelp.com.
You'll see what I mean about the hassles.
Of course, everyone is biased here .. based on the surgery they have chosen so the folks in the lapband forums will try to talk you out of the RNY surgery.
You just have to read and read and come to your own conclusions.
