As part of the workup for my gasrric sleeve procedure, I had to have an endoscopy, in order to determine if I had GERD & how bad it was. Well, it turned out that mine was BAD, so 6 mos. before I had my gastric sleeve, my doctor told me that I would need a procedure called a fundoplication, which relieves the GERD, since GERD only gets worse after the sleeve procedure. In fact, he wouldn't do the sleeve unless I had the fundoplication surgery. So I had it & in July 2021 I had the sleeve. I can count on one hand the number of times I have experienced GERD since having the fundoplication. And it was good preparation for the sleeve, since the dietary restrictions for the first 6 weeks were very similar.
