Anemia, hiatal hernia, gastritis, GERD, LPR, lung problems, thoracic spine issues (pressing on lungs)...

If you suspect a hernia, diaphragm massage may help. Slippery elm, zinc l carnosine, marshmallow root, holy basil, and L glutamine can all help heal the gut. Watch out for L glutamine if you have bipolar or seizures. I personally can't handle it.
