Phil - I have lots more dietary trouble post-op than I ever had in 25 years or more of acid reducers of all types. If the acid reducers are working and you have no symptoms there is no reason to pester the doc, as he suggests.
Now, post-fundo I have serious problems with eating any gas-producing foods (bread, legumes, most vegetables), resulting in vitamin K deficiency unless I eat a salad with spinach every single day. I'm hating salads already! And I make really tasty ones. It's just HAVING to eat them.
I could eat anything I wanted on acid reducers, as long as it was not foods containing my allergen - sulfite. That means I couldn't eat most processed foods, and I still can't. But that's not everyone's problem. Still, keeping a food journal is a good idea.
I live in fear of getting sick and throwing up. I hurt something when I took a painkiller a few days ago, threw up blood and now am having reflux again.
So surgery is not a cure-all, and it leaves you with problems you didn't have before. Stay on the PPIs if they are working!!!!!
