Hi. Sorry to hear you feel like you are not being heard at your doc’s. I’ve battled gut issues for quite some time so I’ll share what helped me. I have no medical training - just patient experience. Two meds I use are Zenpep (or you could try Creon) to aid with digesting fats and Ondansetron (generic for Zofran) for nausea. I do suggest you have your gallbladder checked. It may look fine on a CT Scan but a HIDA test will tell if it’s working. I’d research a lot before having it removed though, as that can come with its own host of problems.
Could you be having bile reflux rather than acid reflux? There are meds to help with that such as Colesevelam or Colestipol (sp?).
Hope this helps some in your health journey.
