Procedure went good. Bad news is that there is no improvement. Good news is that iit is no worse. So. They would like to have the surgery done in the next two months.
Go into it as healthy as you can, as active as you can, with your lungs as healthy as you can get them. Then have a good attitude regardless.
I've found through many interactions that for whatever reason, bypass surgeries can (not always) seem to make men depressed. I suppose something along the same way that hysterectomies tend to make some (emphasis on some) women depressed. It is a visceral reaction, not necessarily one that is solely physical.
This may not apply to you but I do know several men of varying ages that it did. I do recommend that you go into it with as healthy a position as you can.
