I had a revision due to the GERD and heartburn, in the 9 months leading up to it, my surgeon started looking at some data and why there were so many revisions. His findings were that unlike priori where GERD and heartburn were not thought to be an issue passed down is now looking like it is. And due to that he has added new screening questions about more familial conditions that can come into play after the sleeve surgery if that is what what was being considered. And if there is even the slightest hint that it could be there he is opting for bypass.
