I was a long time sufferer until I came across a doctor who correctly diagnosed me with antibiotic resistant chronic h.pylori infection that lead to inflammation of a stomach lining. The test was painless and consisted of capturing air you breathe out into a special bag. After treatment I am symptom free. The antibiotic regimen I went through was the worst I’ve ever experienced due to resistance.
Before the current home-brewed protocol she tried many different things and many different diets that didn’t work, and was told by the doctor there wasn’t much he could do since it had to do with a weak/loose LES.
