I didn't need endo, I went straight on the list after seeing surgeon. I can't remember exactly when I was put on the list but it wasn't long ago so u should be soon. They say it doesn't depend wot surgery u have to how long u wait but I think sleeve is less weight than bypass. That is only because a friend of mine is having bypass and I'm sleeve and I was offered surgery well b4 her even tho she had been in the waiting list b4 me x
