I am just curious. What is the pre op diet like and my MD syas we'll have no problem being approved because Ihave BMI of 43.5, OSA, borderline diabetes/hyperinsukinemia, osteoartghritis, borderline HBP, gout, and finally the new one..asthma. They said after all my qualifications for insurance met I could have surgery in March. Does anyone know of problems with BC/BS of Alabama?
