If this operation requires strict lifestyle changes, then it begs the question of why not just make the lifestyle changes you're going to have to make anyway and skip the surgery part that is exposing you to potential risks? Do you need the threat of literally dying to make the changes? I know that is actually the case for some people. One of my friends actually died (flatlined for like 10 seconds) with a heart condition before he finally made changes to his diet/exercise habits. I think it's pretty common behavior when old habits are deeply entrenched in the reward center of your brain (e.g., people who continue smoking or drinking even after a cancer diagnosis). I hope it works out, in any event. It just seems like putting yourself through a lot more hell than any doctor-mandated diet program would be, but I get that the whole smaller stomach thing is the key difference.
