I’ve been dealing with chronic reflux for about 8 mos now. On PPIs and they don’t seem to do much. But once I get away from my typical routine of work/dadding then all the symptoms vanish, even to the point of being able to eat foods that are not good for reflux: spicy things, tomatoes, a bit of coffee. In my case, this is absolutely a downstream symptom of something mind-body. Already been scoped and got a diagnosis…
He almost certainly suffered minor brain damage during this episode, and later, after about a decade of taking anti-protonic medications for reflux, developed exactly the abnormally rapidly growing abdominal cancer that patients who take anti-protonics apparently develop at a higher rate than similar GERD patients who don't.
I don't mean to give medical advice. I can only describe what happened in my family (which has a heritable deformation in the esophagus, leading to severe GERD). Take it with a grain of salt (and an antacid) as what it is: an anecdote from some anonymous nonexpert on the internet.
Anyhow, good luck. I'm glad to know you're working actively on the problem, not ignoring it as my father did, and I hope you find some long-term relief and peace.
