The place I'm going is kind of a one stop shop. The weight loss center has the surgeons, NUT, and psych all right there. My surgeon is the one who did my endoscopy in fact. We also get a nurse coordinator who keeps track of all of the tests and makes sure you're scheduled for the right appointments.
My first appointment was 4 hours long and during that appointment I had an EKG and all of my measurements taken, then I met with a physician assistant who assists with the surgery and we talked for about an hour. He gave me all kinds of information and answered questions. I briefly met with the surgeon, then I met with the psychologist. She asked me some questions, I was totally honest in my answers and didn't have any problems. The dietitian came in and we discussed how I should be eating and what eating would be like after surgery etc. She gave me a packet full of meal suggestions and has me logging my food with a plan to keep calories under 1100, Protein about 100 grams and limit net carbs to less than 80 each day.
I had all of my blood tests at my PCP and he submitted the orders for my endoscopy with the surgeon too. I had a follow up after two weeks with NUT and psych. I haven't been having any issues so it was a quick appointment. Now I go in on the 11th for my final surgical review and I'm tentatively scheduled for surgery on the 25th!
As a self-pay I'm on a fast track. Most insurance who cover WLS require you to go through a 3 or 6 month medical monitored weight loss program prior to surgery. I did have to sign a form stating that I would not gain weight between my first appointment and my surgery, but that's all.
