Excessive Burping Causes

Common Causes for Excessive Burping

There are numerous causes for excessive burping. As we take bites of food or sip a drink, air tends to travel down with the food where it ends up in the stomach. Usually the air will sit at the bottom of the stomach under bile, food, and drink until suddenly a shift causes the air bubble to the surface where it then slips right up the throat and out of the mouth. The thing is, not everyone is as sensitive to collections of air in the stomach. In fact one person could have a stomach virtually full of air and he may not belch, yet another person could have a few little trapped air bubbles that decide to make a dash for it (usually at an inconvenient time).

Swallowing Air

Swallowing air is one of the most common causes for excessive burping. This is especially common among people who chew with their mouth open, as this allows air to enter the mouth and mingle with the food on the way down to the stomach. There is also an increased chance of taking in air while drinking with a straw. Straws work on suction but many people also tend to fidget with straws which can result in increased intake of air that is pushed down with whatever drink that is being consumed. Chewing gum also allows one to swallow air because the repetitive chewing causes air to mix with the saliva that is then swallowed down to the stomach.


An allergy is another addition to the list of causes for excessive burping. Common allergies to foods such as milk, eggs, nuts, wheat, and soy have shown to produce excessive belching, bloating, and general stomach upset. The belching may also be accompanied by a burning or itching sensation in one’s throat, heartburn, redness of the skin, or even a rash. Gas caused by an allergy is likely to be longer lasting than typical gas. To prevent this type of reaction one must do a trial and error among different foods in their diet until they locate the culprit. After that it is merely a case of avoiding the allergen.

Fizzy Drinks and Whipped Foods

It is no great secret that carbonated (also known as “fizzy”) drinks are a sure way to obtain a stomach full of gas. Although these drinks taste fantastic on the way down, they don’t seem to have the same effect when a burp escapes during the board meeting or in the middle of a conversation! Unfortunately, another partner in crime when it comes to foods with high air content includes soufflés, mousses, whipped cream, and even omelets. These foods are beaten or whisked so much that air is literally forced into the food particles. This is done so to provide a light and airy texture to the food that stays whether the food is cooked or served cold. No matter which way you have them, they are definitely more likely to give you a good bout of the burps!


Few people give thought to nervousness being a culprit of gas, but think about it. Have you ever been so nervous that you found yourself uncharacteristically and inexplicably gassy? Whether the gas comes out of the top or the bottom end, there is a true link between gas and nerves. Some people, when they become nervous, attempt to calm their nerves by taking in huge breaths of air, or by breathing frequently in an attempt to overcome cotton mouth. Although one’s intentions are pure, the body doesn’t always send every bit of air straight back out on an exhalation, therefore air becomes trapped in the stomach just waiting for the time that it can make itself known.
