Hi. Thanks for your query. Noted the history and understood the concerns. Your symptoms of heartburn and burping lok to be due to GERD that is gastroesophageal reflux disease. Additional complaints of feeling fullness, bloating, indicate that there may be an associated intestinal problems. Hence I would advise you the following in such a situation: Tests of stool for a few day Tests of blood for CBC, diabetes, liver function. Upper GI Endoscopy. A course of an antibiotic, metronidazole. Probitoics, bananas, yogurt and activated charcoal tablets help further. PPI like Omeprazole, domperidone. Continue antacids particularly when on empty stomach. CT scan if needed and colonoscopy too if the above measures do not help; go for consultation with a Gastroenterologist for further clinical evaluation,correlation with investigations and proper management.
