I am early pre-op and although I'm getting the bypass, I'm also close to your weight and have a lot of physical problems. My fitness level at this point is practically non-existent so one of my questions in my first consult appointment was whether I should be concerned about undergoing surgery at such a low level of mobility and health in general. This was a physician's assistant and I'm sure each doctor would respond based on your individual circumstances, but she said that the surgery these days is really not that hard on a body and recovery is manageable regardless of whether or not you can exercise. Her words: 'people who have the surgery don't need to run to lose weight, they need to lose weight to run.' Granted, she also sent me home with a print-out for some simple resistance exercises to try. 😄
