Will Aetna Insurance cover Lap Band or Gastric Bypass?

[LiveLoveLaugh]

I have been trying everything under Weight Watchers, Nutri System, Diet Pills along w/ exercises but have not been able to shed the extra weight ( 138 pds. ). In the last 6 months, my test results are high for cholesterol and triglycerides and I have been put on cholestrol medication to help reduce the level. Just last week, I was told by my doctor that I was boderline diabetic and I have a fatty liver which she's very concern with because it can get worse. So she has put in a refferal for these two options. I don't know what the insurance covers or do not does anyone know?
