My best friend and I shared more than a decade of dieting attempts..some more successful than others...and in 2005 we both pursued weight loss surgery. She had gastric bypass because her insurance covered it. I got my lap band because I had to pay for the surgery myself. We have both been fantastically successful and we both love what we chose. There can be complications with both...but in our case it was me who suffered a complication totally out of my control and had to have my band replaced which was NO FUN and very expensive. But even so I am still very happy with the Lap Band. I had a 37BMI to begin with so it seemed that for me the Dr.s preferred to do the Lap Band surgery on me anyway. It's certainly your choice but based on my own and my best friends personal experience I think you might consider the gastric bypass. If you have problems with it later, there are Dr.s who are placing lapbands over the bypass so a lap-band would still be a back-up option later if it was needed.
