The fundoplication was done to keep the acid out of the esophagus. If it works, and that can take several weeks, there is no reason to take PPIs anymore. GERD is not caused by an overproduction of acid but is acid getting into the esophagus. The stomach is supposed to be acid. We only took the PPIs to stop the acid because it was wrecking our esophagi.
But surgeons normally do warn that fundoplication does not necessarily mean complete success in stopping reflux, and many patients still need PPIs to keep the stomach non-acid.
Most of us were on liquids or very soft foods for a long time. I had to watch very carefully for 3 months and avoided chunks of beef for 6 months. I still avoid large pills, but then I never could swallow them before either.
Fundoplication will also not cure other esophageal problems like nutcracker, or in my case, food triggers/allergies/sensitivities. My stomach still heaves, trying to reflux, when I eat too much of any of my triggers.
I have had absolutely no remission in the gas and gurgling after 8 months, and I don't expect to. My "new valve" is good enough to keep me from burping much, so the gas has to go the other way out. The only solution is to avoid "gas producing foods." Forever. You can find good lists and explanations online.
