What causes bubble guts after I eat anything?

1st, why RU gassy? Feeling full of "gas" may reflect malabsorption of food (like gluten, lactose), intake of poorly digested food, eating foods that promote gas (beans, fizzy drinks). Sometimes its more complicated--aerophagia, stomach emptying too slowly, bacterial overgrowth syndrome, delayed intestinal function, partial obstruction from any cause, infection, rectum problems, &/or pelvic pathology outside the gut.
