Beer Burps: Why Do They Happen?

Beer is a carbonated beverage, which means it contains carbon dioxide gas. This gas is infused during the production process and appears as tiny bubbles in the drink. When you drink beer, the carbon dioxide collects in your stomach and enters your digestive system. This build-up can cause discomfort, so you burp to release the gas. The faster you drink, the more air you swallow, which can also lead to burping as your body tries to relieve the pressure in your chest or abdomen.

Carbonation

The carbon dioxide in beer creates tiny bubbles that accumulate in the stomach and enter the digestive system. This buildup of gas can cause discomfort, leading to the body's natural reflex of burping to release the excess gas. The gas travels up the oesophagus and exits the mouth, often accompanied by a distinctive croaky sound, resulting in a burp or gastric belch.

The amount of carbonation in beer can vary depending on the manufacturer and the desired level of froth and fizz. Different beers will have different volumes of carbon dioxide, which can contribute to the intensity of burping.

To reduce burping while drinking beer, it is advisable to drink slowly and avoid chugging, as rapid consumption can increase the amount of air swallowed, exacerbating the problem. Additionally, avoiding the use of a straw, reducing talking or chewing gum while drinking, and not smoking can help minimise burping.

While burping can be embarrassing, it is a normal and common occurrence after consuming carbonated beverages like beer. However, excessive burping or discomfort may indicate gastroesophageal reflux disease (GRED), which is characterised by stomach contents being pushed upwards into the oesophagus. If symptoms persist, it is recommended to consult a doctor for advice and potential treatment options.

Swallowing air

When you drink beer, especially if you drink it quickly, you tend to swallow a significant amount of air along with the liquid. This swallowed air accumulates in your stomach and digestive system, creating a buildup of gas that can become uncomfortable. To relieve this discomfort, your body naturally expels the excess air through burping.

The act of swallowing beer rapidly, often referred to as "chugging," exacerbates the amount of air you ingest. This rapid consumption of beer leads to larger air pockets surrounding the liquid as it travels down your esophagus to your stomach. The excess air increases the pressure in your chest and abdomen, triggering the urge to burp.

Additionally, the carbon dioxide gas from the beer itself contributes to the buildup of gas in your stomach. The combination of swallowed air and carbonation from the beer amplifies the intensity of burping. For individuals with sensitive stomachs, the effect can be even more pronounced.

To mitigate burping while drinking beer, it is advisable to slow down your consumption and avoid chugging. This allows you to ingest less air and reduce the discomfort associated with excess gas in the digestive system. Additionally, avoiding activities that increase air swallowing, such as chewing gum or smoking, can further help reduce burping.

Drinking too much beer

If you are experiencing any of these issues, it is important to speak to a medical professional. They can advise you on the best course of treatment, which may include cutting back on or quitting alcohol.

Gas build-up

Beer is a carbonated beverage, meaning it contains carbon dioxide, which is a gas. When you drink beer, you are consuming not only the liquid but also the gas it contains. This gas can get trapped in your oesophagus, the tube that carries food and liquid to your stomach. As a result, the gas can then travel back up the oesophagus and escape through the mouth as a burp.

The gas in beer can build up in the body because it is not always able to be absorbed by the stomach. The stomach has a limited capacity to absorb gas, and when it is exceeded, the excess gas has to go somewhere. As a result, the gas escapes through the mouth in the form of a burp. Additionally, the carbon dioxide in beer can also cause a build-up of air in the stomach, which can also lead to burping.

There are a few ways to reduce gas build-up when drinking beer. Firstly, drinking beer slowly can help, as it gives the stomach more time to absorb the gas. Additionally, avoiding carbonated beverages altogether can help reduce gas build-up, as they are a common cause of burping. Drinking through a straw can also help, as it reduces the amount of air swallowed.

Health implications of frequent burping

Frequent burping can sometimes indicate an underlying health issue. For example, burping more than four times after a meal could be a sign of gastroesophageal reflux disease (GERD) or indigestion. If you are concerned about the amount you are burping, it is recommended to consult a doctor. They will be able to advise on any necessary lifestyle changes or medical treatments.

Gastroesophageal reflux disease (GRED)

Gastroesophageal reflux disease (GERD) is a condition where acid flows back from the stomach into the oesophagus, causing heartburn. It can be treated with over-the-counter medication, but if it occurs frequently, changes to diet or prescription drugs may be required.

GERD is the most relevant condition in both types of belching: gastric belching and supragastric belching. Belching is a common phenomenon, but it becomes bothersome when it is excessive. GERD patients often report frequent burping. In fact, a study found that the prevalence of belching in GERD patients ranged from 4.1% to 75.6%.

Impedance-pH monitoring can be used to classify belching into two types: gastric belching and supragastric belching. The former is a physiological mechanism to vent swallowed air from the stomach, whereas the latter is a behavioural disorder. Recent studies have found that excessive supragastric belching may be responsible for typical reflux symptoms such as heartburn, regurgitation, or chest pain.

The combination of psychological treatment and conventional treatment can improve outcomes for patients with PPI-refractory GERD and excessive supragastric belching.
