My dr/clinic had several requirements before surgery. The first was the surgical evaluation/education meeting, the psychological evaluation, attend 1 meeting with the dietician/nutritionist, attend 1 support group meeting, and once my surgery had been scheduled I had to attend an all day education class where everything was reiterated and we met with the surgeon, a psychologist, an exercise trainer and the nutritionist. All were very informative and I am thankful they made me go through that because I knew exactly what was going to happen, what things to look for if I had a problem and exactly what I needed to do after surgery to be successful.
