Aerophagia means swallowing too much air, and it is more common than most people think. It can cause bloating, burping, abdominal pain, and general digestive discomfort. The good news is that most cases of aerophagia can be treated with simple changes to your eating habits and daily routine. This article explains what causes it, what to watch for, and when to talk to your family doctor or visit a walk-in clinic.
What Is Aerophagia?
Aerophagia comes from the Greek words for “air” and “eating.” It happens when a person swallows excess air, usually during meals or while drinking. That air gets trapped in the stomach and digestive tract, leading to uncomfortable symptoms.
Everyone swallows a small amount of air while eating and drinking. However, when someone swallows significantly more than normal, the build-up can cause real discomfort. In most cases, the condition is harmless and easy to manage at home.
Common Causes of Aerophagia
There are many reasons a person may swallow too much air. Most causes are linked to everyday habits and behaviours rather than serious medical conditions.
Eating and Drinking Habits
Eating too quickly is one of the most common causes of aerophagia. When you rush through a meal, you tend to gulp air along with your food. Talking while eating, chewing with your mouth open, or eating while distracted can all make this worse.
Drinking carbonated beverages is another major trigger. Sodas, sparkling water, beer, and sparkling wine all introduce bubbles of gas directly into your stomach. Drinking through a straw can also increase the amount of air you swallow.
Chewing gum frequently causes aerophagia as well. Each time you chew, you swallow small amounts of air. Over time, this adds up and leads to bloating and burping.
Poor Posture During Meals
Your body position at the table matters more than you might expect. Slouching or hunching over your plate can affect how the valve between your oesophagus and stomach works. As a result, more air can enter your digestive tract than normal.
Oral Health Problems
Gum disease, missing teeth, or ill-fitting dentures can interfere with proper chewing. When food is not chewed well, you may swallow larger pieces along with extra air. People with loose dentures also tend to produce more saliva, which can trigger more swallowing and increase the risk of aerophagia.
Smoking
Smokers regularly inhale and swallow air as part of the act of smoking. This makes aerophagia more likely, especially in heavy smokers. Quitting smoking benefits digestion in many ways, and reducing aerophagia is one of them.
Stress and Anxiety
Emotional stress and anxiety can change the way you breathe and swallow. Many people unconsciously swallow more often when they feel nervous or tense. Furthermore, stress often leads to rushed or irregular eating habits, which increases the risk of swallowing excess air.
CPAP Machines and Medical Causes
People who use a CPAP machine for sleep apnea sometimes develop aerophagia. The machine pushes pressurised air through the airway to keep it open during sleep. If the pressure is set too high, air can travel down the oesophagus into the stomach instead.
In rare cases, aerophagia can occur as a side effect of non-invasive ventilation used for certain respiratory or cardiovascular conditions. In these situations, air trapped in the gastrointestinal tract can sometimes be detected with a stethoscope placed over the abdomen. If not addressed quickly, it can lead to gastric distension, which is serious and requires prompt medical attention.
Some cognitive conditions present from birth can also affect the coordination between swallowing and breathing, leading to chronic aerophagia. In these cases, a doctor may recommend specific medications or behavioural therapy as part of a treatment plan.
Aerophagia in Babies
Infants are particularly prone to swallowing air during feeding. Breastfed babies can take in air if the milk flows very quickly and becomes frothy. Bottle-fed babies may swallow air if the bottle nipple is the wrong size or if feeding is rushed. Burping your baby regularly during and after feeding helps release this trapped air.
Symptoms of Aerophagia
The symptoms of aerophagia are mainly digestive. Most people experience a combination of the following:
Bloating — a feeling of fullness or tightness in the abdomen
Excessive burping — frequent belching, sometimes immediately after eating
Flatulence — increased passing of gas
Abdominal pain or cramping — caused by pressure from trapped air
Nausea — an unsettled feeling in the stomach
Acid reflux or regurgitation — stomach contents moving back up into the throat
In most cases, symptoms are mild and come and go depending on what you eat and drink. However, if symptoms are severe, persistent, or accompanied by vomiting or unexplained weight loss, it is important to seek medical advice.
How Aerophagia Is Diagnosed
There is no single test for aerophagia. Instead, your family doctor will ask about your symptoms, eating habits, and lifestyle. They may ask about your daily fibre and water intake, which foods seem to trigger symptoms, and whether your discomfort is mild, moderate, or severe.
Your doctor may also want to rule out other digestive conditions that cause similar symptoms. For example, lactose intolerance, irritable bowel syndrome (IBS), and gastroesophageal reflux disease (GERD) can all produce bloating and discomfort. To rule these out, your doctor may order tests such as:
Abdominal ultrasound
Upper endoscopy
CT scan of the abdomen
Complete blood count (CBC)
Barium swallow study
According to Mayo Clinic’s guidance on gas and digestive symptoms, keeping a food and symptom diary before your appointment can help your doctor identify patterns and reach a diagnosis more quickly.
Treatment Options for Aerophagia
Most people with aerophagia do not need medication. Simple lifestyle and dietary changes are usually enough to bring relief. However, some cases may benefit from additional support.
Lifestyle and Dietary Changes
The most effective treatment for aerophagia starts with changing how you eat. Slowing down at mealtimes and chewing food thoroughly gives your body time to process each bite without taking in extra air. Try to eat without distractions like your phone or television.
Reducing or eliminating carbonated drinks makes a noticeable difference for most people. In addition, cutting back on chewing gum, hard candies, and other foods that encourage open-mouth chewing can also help.
Eating smaller, more frequent meals throughout the day puts less pressure on your digestive system. Avoid foods that are hard to digest, overly spicy, undercooked, or heavily processed. Getting enough dietary fibre from whole grains, fruits, and vegetables supports healthy digestion overall.
Sitting upright during and after meals helps keep the valve between your oesophagus and stomach working properly. Good posture at the dinner table is a simple but effective habit to develop.
Managing Stress
Because stress and anxiety contribute to aerophagia, managing your mental health is an important part of treatment. Deep breathing exercises, mindfulness, regular physical activity, and adequate sleep all help reduce stress levels. If anxiety is a significant factor, speaking with a mental health professional may be beneficial.
Medications
In some cases, over-the-counter remedies can help relieve symptoms. Simethicone (found in many gas-relief products available at Canadian pharmacies) helps break down gas bubbles in the digestive tract. Activated charcoal supplements and certain herbal teas may also offer relief for some people.
Always speak with your pharmacist or family doctor before starting any new supplement or medication. Some products can interact with other medicines or may not be appropriate for everyone.
For people using CPAP machines, adjusting the air pressure settings with the help of a sleep specialist can significantly reduce aerophagia symptoms. Do not adjust CPAP settings on your own without professional guidance.

When to See a Doctor
Mild and occasional aerophagia is rarely a cause for concern. However, you should make an appointment with your family doctor or visit a walk-in clinic if:
Symptoms are severe or getting worse over time
You experience significant abdominal pain or cramping
You have unexplained nausea, vomiting, or loss of appetite
You notice changes in your bowel habits or unexplained weight loss
Symptoms interfere with your daily life or sleep
You use a CPAP machine and experience regular bloating or discomfort
Your provincial health plan covers visits to your family doctor for digestive concerns, and most walk-in clinics can also assess and refer you if needed. Early assessment helps rule out other conditions and ensures you get the right support.

Frequently Asked Questions About Aerophagia
What is aerophagia and what causes it?
Aerophagia is a condition caused by swallowing too much air, usually during eating, drinking, or as a result of habits like chewing gum or smoking. Common triggers include eating too quickly, drinking carbonated beverages, and stress or anxiety. In some cases, aerophagia can also be linked to CPAP machine use or certain medical conditions.
How do I know if I have aerophagia?
The most common signs of aerophagia include frequent burping, bloating, abdominal discomfort, and excess gas after eating or drinking. If these symptoms happen regularly and are linked to your eating habits, aerophagia may be the cause. Your family doctor can help confirm a diagnosis and rule out other digestive conditions.
Can aerophagia go away on its own?
Yes, in many cases aerophagia improves significantly once you identify and change the habits causing it. Eating more slowly, avoiding carbonated drinks, and reducing stress are often enough to resolve symptoms without any medication. However, if your symptoms persist or worsen, it is a good idea to speak with a healthcare provider.
Is aerophagia the same as excessive burping?
Excessive burping is one of the main symptoms of aerophagia, but they are not exactly the same thing. Aerophagia refers specifically to the act of swallowing too much air, while excessive burping is the body’s way of releasing that trapped air. Other symptoms like bloating and abdominal pain often accompany the burping.
Can a CPAP machine cause aerophagia?
Yes, CPAP machines used for sleep apnea can cause aerophagia if the air pressure is set too high. The pressurised air can travel down into the stomach through the oesophagus rather than staying in the airway. If you suspect your CPAP is causing digestive symptoms, talk to your sleep specialist about adjusting the pressure settings.
What foods should I avoid if I have aerophagia?
People with aerophagia are generally advised to avoid carbonated drinks, overly spicy or heavily processed foods, and foods that are difficult to digest. Chewing gum and hard candies should also be limited, as they encourage swallowing air. Keeping a food diary can help you identify your personal triggers and make targeted dietary changes.
