For bloating, refluxing you can try to figure out if you have food triggers. My allergist helped me get mine under control.
I kept a food log for a couple of months, listing foods, drinks, medications, and what symptoms and the time of everything. After I had a list of possible foods, I did "challenge testing." You eat something simple, like bread or milk - just a teaspoon (or maybe a tablespoon if you think you may need to start with a higher quantity) to start. Then wait 20 minutes and record any symptoms. Then you double the dose and wait another 20 minutes. 1,2,4,8, and ending with 16 teaspoons or bites or whatever measure. Wait at least a couple of hours and go on to another food.
I ended up with a weird list of foods: gelatin, maple syrup, nearly all processed foods, pork, corn syrup ... and much more. When I started googling food allergies and the specific foods I came up with sulfites. There was my whole list! You could end up with MSG, which is in just about the same foods, or something completely different.
Eliminating specific food triggers stops the heaving, refluxing of the stomach. It won't cure a bad valve or stop acid in any way. Now, after haaving had to have surgery because of a bad accident, I don't reflex into my esophagus any more, but my stomach can still heave.
It's possible for trigger foods, or just refluxing for unknown reason, to trigger the heart to beat very fast. I still get this when I eat my trigger foods. It's called cardio-esophageal reflex.
