Belching and hiccups may be functional dyspepsia, but may also be gastritis, gastric ulcer or even gastric cancer, which requires further gastroscopy to confirm the diagnosis. Patients should pay attention to their diet, avoid spicy and stimulating foods, quit smoking and drinking, eat more pasta and avoid high sugar, high fat and other high-calorie foods. The above symptoms can be relieved by eating less gas-producing foods in general. The above symptoms can be helped by medications such as omeprazole, pantoprazole, rabeprazole and other acid-suppressing drugs; as well as gastric mucosa-protecting drugs such as Schilling granules; plus gastric motility drugs such as fastidious also known as mosapride and digestive enzymes.
