I'm considering getting a balloon to help me get my weight down. I've read that you have to be between 30-40 BMI. Can i still be approved for it if i am a bit over 40BMI? im currently 250-260 at 5'4. I don't want to get a serious surgery but i desperately need to lose this weight. I'm also looking for a good doctor who can do it in Portland, OR area.
