You will be more successful doing this as a healthy person. Why wait until you're sick and the risks of surgery go up? As a.c. example, if you know the transmission in your car is bad, do you fix it now our continue driving it until you're stranded in the road? Why put your body through that? You have the best chance of success if you're still healthy. Good luck to you!!! Sent from my LG-H811 using BariatricPal mobile app
