Chronic reflux as a symptom is almost always initially treated by PPIs because the cause among white collar workers is assumed to be chronic stress[1]. Since doctors can't "treat stress" only its symptoms, they will just tell you to try and manage stressors in your life yourself. Maybe suggest counseling but in general they are limited in what they can do. What they can do, if you are persistent in the complaint, is to just run through all the other less likely causes of it.
I was lucky omeprazole worked for me the first time. I knew exactly what was stressing me out 24/7 and the acid reflux and frequent belching combined with the "pit in my stomach" feeling was all too common and connected around my main stressor. In my case, it started 8 months after accepting a role shift from engineering into management. I was cautiously excited initially, but it just soured very quickly. I would feel physical angst parking at work every morning trying to remind myself of all the web of political infighting "what our team is hiding from this other team", "who we can discuss what with", "how that other team is actively undermining us and their other downstream partners, but how we are circumventing that" how to 4d chess maneuver yourself in the most counterproductive ways possible. It was illuminating on where a lot of those special "business requirements" come from sometimes, but it just wasn't for me. Cutting that out was a massive relief
