Hard to get approval

I was just curious if anyone has any experience out there with how inusrance companies llok at things. I am currently in a weight loss program for the lap band and have been dieting for 6 months and excercising with documented gym time for 3 months. I have PCOS which consists of a co-morbidity along with high blood pressure, GERD, and knee and foot pain. Do you think they will approve me? I am so anxious right now because during the first 2 months of my diet I actually gained weight. I am now below my starting point but I am so scared and filled with anxiety. On what grounds will they approve or deny this?

These things need to be looked at

1) do you or have you checked you policy to see if they cover WLS under your contract?

2)  If they allow WLS have you checked the benefits and the criteria that needs to be met?
