Experiencing acidity every few hours, belching, and hunger-related headaches suggests your stomach might be producing excess acid or has mild inflammation, such as gastritis or a peptic ulcer. While pantoprazole and albendazole offered partial relief, the root cause?such as a common Helicobacter pylori bacterial infection?may still need to be addressed. Please be reassured that these issues are very common and highly treatable. I highly recommend consulting a healthcare professional. They may suggest a simple test for Helicobacter pylori or adjust your acid-suppressing therapy. In the meantime, eating smaller, more frequent meals can help keep your stomach acid stable.
