I have had some of those same concerns. My doctor told me that after the healing process you can be normal and do all kinds of activities including twisting, turning, etc... so jazzercise should be good. As far as 20 years from now, if there are issues it can be removed. But those 20 years will be a better quality of life if done properly. Last going to the hospital for complications, yes they may not have expertise in the ER for bariatric lap bands but they can call the doctor who does and they know life saving techniques to save you regardless. My doctor advised me that no lap band complication would be life threatening. I think all of these are natural fears and questions and you are right to ask all of them to your doctor. I am fearful everyday of my choice but I know if I do not do something I will be worse off. My surgery is scheduled for next Monday, 11/23. No turkey day for me. :thumbup: Everytime I get sad for missing the food, I think of the long term positive effects. Keep the faith!
