Abdominal bloating can be curbed by making such changes in your eating habits as avoiding swallowing too much air, which can occur while chewing gum, drinking carbonated beverages, smoking, using a straw, or eating too fast. Foods that cause gas include cabbage; legumes; onions; artichokes; mushrooms; turnips; some fruit such as pears, apples, and peaches; whole grains; sugar-free candy; juice; high-fructose corn syrup drinks; fatty foods; and sweets. Avoiding milk and dairy products may help determine whether you are lactose intolerant. Eliminating gluten from your diet may also help you determine whether you have celiac disease. Some over-the-counter medications to reduce gas may help with bloating, as may probiotics.
