How many times have you attempted weight loss? For BCBS, you have to spefically name every type of weight loss you've attempted. For instance, I did Slim Fast, Weight Watchers, Nutrition System, Zone, self-imposed exercises and diets. I think that they need at least 10 years (but don't quote me) of weight loss effort before they will approve. Also, have you finished the requirements given to you by your surgeon?
Hope that this info helps!!
