I understand how exhausting it must be to deal with persistent acidity for a year without relief. Since standard treatments like proton pump inhibitors and H2 receptor antagonists haven't helped, the next step is finding the root cause. I highly recommend consulting a gastroenterologist. They may suggest investigations like an upper endoscopy to examine your stomach, a 24-hour pH study to measure acid levels, or esophageal manometry to check muscle function. Testing for H. pylori infection is also crucial. Depending on these results, alternative treatments like prokinetics, baclofen, or specialized therapies can be explored.
