Last year I had H. pylori with nausea and heaviness after meals. After treatment, nausea is gone. Now I mainly have upper stomach fullness (2 fingers above navel) after pooping (30–45 mins or more), occasionally after eating on an empty stomach in the morning. Stool and flatulence have always been foul-smelling(since 2022) . No acidity , no stomach pain or cramps, no diarrhoea. SIBO test was negative. This year i again tested myself for h.pylori and its negative.
Vitamin/mineral levels are mostly normal. Endoscopy is normal. I have already tried medicines for the symptoms but they don’t work. I want to identify the root cause, not just manage symptoms. Which tests do you suggest to evaluate this?
