You should see gastroenterologist.

Bloating (with burping, early satiety, nausea, heartburn) may be from H. pylori infection of stomach. There's a bretah urea test for diagnosis. Left sided bloating may be from diverticulitis. x-ray with barium enema is for dx.

You can also have two diet trials: lactose free diet (no dairy) for two days, and low-fructose diet (no fruits or any fruit product, no artificially sweetened food which contains sorbitol or high fructose corn syrup) for 3-4 days.
