Hiya... not nosey at all. Thats what is so brilliant about this forum, you can ask anything.
For me, I was already fairly certain I wanted bypass over band before my hospital appointment. My own research has shown me that the bypass is better suited to my eating habits. I eat large portions, which will be restricted by the bypass as well as fatty/sugary foods which could just slip through if I had the band. I personally felt that the band required more willpower, and whilst I am currently feeling very strong and focused about WLS, I know I will have my weak moments and the fear of dumping will hopefully stop me indulging in the wrong foods.
At the hospital, the doctor told me that a band could still potentially leave me obese after I had stopped losing weight, due to the amount I need to lose. That was the deciding factor for me. Im not putting myself through all this to still be fat at the end of it.
You are asking all the right questions hun. Keep on researching as much as humanly possible. You will reach the right decision for you.
