I had my consultation on 3/29 and my surgery was scheduled for 5/1. I only needed 30 days with my insurance. I was given a list of things/appointments that I need to compete before the surgery date. If all is complete, my surgery is a go within 33 days of my consultation. The hardest part is scheduling the other Dr appointments within that time restriction. Also for me, I was not required to diet before hand. I have no required Weightloss before surgery.
