I got my band in december of last year and I'm really glad I went with the band instead of RNY for the following reasons.
-I liked that the band wasn't permanant. If something serious happened I could always get it taken out. Or if for some reason I didn't like the band then I could take it out and then go with RNY.
-I'm young so if I get pregnant it is safer to have the band.
-I like the fact that if I loose restriction I can always go in and get another fill instead of just dealing with your stomach stretching (I have heard about a new procedure that can make your stomach smaller if you've had RNY and it's stertched out.)
-I've heard about issues with people who have had RNY having problems with really smelly gas and burping. I didn't really want to deal with this. I'm in school and I'm sure it would be no fun being the "smelly girl".
-I don't like the sound of dumping or malabsorbtion.
With that being said I love my band and I'm glad I went with it!
