Hi..you can ask for a referal frm ur reg dr, or like I did, I went a seminar for gastric bypass (or lapband if that is the type of surgery u wnt) and they pretty much walk you thur the procedure...
Good luck!
You need a referral from your Dr. but make sure that the Dr. he chooses for you is a good one, and if you know anyone the works in the local hospital they can kinda give u a heads up on which Dr. to choose.
