Using a CPAP machine can cause mild stomach bloating and gas due to swallowed air, but it doesn’t directly make you fart more frequently.
Understanding How CPAP Machines Work
CPAP, or Continuous Positive Airway Pressure, machines are a cornerstone treatment for obstructive sleep apnea. They work by delivering a steady stream of pressurized air through a mask, keeping the airway open during sleep. This prevents interruptions in breathing that can cause snoring, daytime fatigue, and other health issues.
The airflow from the CPAP machine is continuous and slightly pressurized, which can sometimes lead to unintended side effects. One common concern among users is whether this airflow causes digestive discomfort or increased flatulence. The question “Does CPAP Make You Fart?” stems from the sensation of bloating or gas some users report.
Why Might CPAP Use Lead to Gas or Bloating?
The main reason CPAP therapy might contribute to gas buildup is aerophagia—swallowing air unintentionally. When you breathe through the mask under positive pressure, some air can slip into your esophagus and stomach instead of your lungs. This extra air in the digestive tract can cause bloating, burping, and sometimes flatulence.
Aerophagia isn’t unique to CPAP users; it can happen with any situation where excessive air is swallowed. However, the positive pressure from the machine increases this risk. The swallowed air accumulates in the stomach and intestines and then needs to be released either by burping or farting.
It’s important to note that while aerophagia may increase gas volume temporarily, it does not cause any underlying gastrointestinal disease or chronic digestive problems.
Factors That Influence Aerophagia in CPAP Users
Several factors determine how much air you might swallow during CPAP therapy:
- Mask Fit and Type: A poorly fitting mask may cause you to breathe more forcefully or swallow excess air.
- Pressure Settings: Higher pressure levels can increase the likelihood of swallowing air.
- Breathing Patterns: Mouth breathers often swallow more air compared to nasal breathers.
- User Adaptation: New users tend to experience more aerophagia until they get used to the therapy.
Adjusting these variables under medical supervision often reduces symptoms like bloating and gas.
The Science Behind Air Swallowing During CPAP Use
Swallowing air is called aerophagia, which literally means “air eating.” It occurs when excess air enters the digestive tract instead of being expelled through breathing. In normal breathing, minimal amounts of air enter the stomach. But with positive pressure devices like CPAP machines, this amount can increase.
Once swallowed, this trapped air stretches the stomach walls and intestines. The body naturally tries to expel it through belching or passing gas. This is why some people notice increased burping or farting after starting CPAP therapy.
However, studies show that while aerophagia is common among CPAP users, it rarely leads to severe digestive issues. Most symptoms are mild and diminish as users adjust their equipment or sleeping habits.
Aerophagia Compared With Other Causes of Gas
Gas production in the gut mostly comes from digestion—fermentation of foods by bacteria produces gases like methane and hydrogen. Aerophagia adds a mechanical source of gas by introducing swallowed air.
Here’s a quick comparison:
| Source of Gas | Description | Relation to CPAP Use |
|---|---|---|
| Aerophagia (Swallowed Air) | Air enters stomach due to swallowing during breathing. | Increased risk with positive airway pressure; direct link. |
| Bacterial Fermentation | Bacteria break down undigested food producing gases. | No direct connection; diet-dependent. |
| Mouth Breathing Without CPAP | Swallowed air due to dry mouth or rapid breathing. | No positive pressure; less intense than with CPAP. |
This table shows that while aerophagia linked with CPAP therapy can add some extra gas volume, it’s just one factor among many influencing flatulence.
Common Symptoms Linked With Aerophagia on CPAP Therapy
People who experience aerophagia during CPAP use often report:
- Bloating: A feeling of fullness or tightness in the abdomen caused by trapped gas.
- Belly Rumbling: Audible gurgling sounds as gas moves through intestines.
- Burpiness: Frequent belching as swallowed air escapes upward.
- Flatulence: Increased passing of intestinal gas (farting) as body expels trapped air downward.
These symptoms are usually mild but can be uncomfortable enough for some users to consider stopping therapy if not addressed properly.
Tackling These Side Effects for Better Comfort
If you notice these symptoms after starting your CPAP treatment, there are several practical steps:
- Check Mask Fit: Ensure your mask seals well without leaks but doesn’t force you to swallow extra air.
- Tweak Pressure Settings: Talk with your sleep specialist about lowering pressure if it’s too high initially.
- Mouth vs Nasal Breathing: Using a full-face mask or chin strap may help reduce mouth breathing and swallowing excess air.
- Easing Into Therapy: Gradually increasing usage time helps your body adjust better over days or weeks.
Often these adjustments greatly reduce aerophagia-related discomfort without compromising treatment effectiveness.
The Role of Diet and Lifestyle in Managing Gas on CPAP
While aerophagia introduces swallowed air into your system during sleep, what you eat also plays a big role in how much gas builds up overall. Foods rich in fiber ferment easily in your gut bacteria causing natural gas production.
Cutting back on common culprits such as beans, carbonated drinks, onions, garlic, and certain vegetables may help minimize combined effects with aerophagia. Also:
- Avoid chewing gum before bed — chewing increases swallowed air even before using your machine.
- Avoid smoking — smokers tend to swallow more saliva and air unconsciously.
- EAT SLOWLY — rapid eating causes more swallowed air during meals that carries over into nighttime digestion.
A balanced approach addressing both machine-related factors and diet will deliver better relief from bloating and flatulence symptoms.
The Truth About Does CPAP Make You Fart?
So here’s the bottom line: Does CPAP make you fart? The answer isn’t black-and-white but leans toward yes—indirectly. The machine itself doesn’t produce gas chemically or biologically but increases swallowed air that must exit somehow.
This means some increase in flatulence might occur initially due to aerophagia caused by positive airway pressure pushing extra air into your stomach and intestines during sleep.
However:
- This effect tends to be temporary as many users adapt within days or weeks.
- The degree varies widely depending on mask type, pressure settings, user habits, and diet.
- If unmanaged properly, symptoms like bloating can become bothersome but rarely dangerous or permanent.
Understanding this mechanism helps reduce anxiety about “making you fart” excessively while highlighting simple fixes that improve comfort without sacrificing sleep quality.
The Importance of Continuing Therapy Despite Minor Side Effects
CPAP therapy dramatically improves quality of life for people with sleep apnea by preventing dangerous drops in oxygen levels overnight. Even if minor side effects like mild bloating occur at first due to aerophagia-related gas buildup, quitting isn’t advisable without consulting your doctor.
Most side effects resolve once equipment fit improves or pressures are fine-tuned. Stopping treatment risks serious consequences including cardiovascular problems caused by untreated apnea episodes.
Your healthcare provider can guide adjustments tailored specifically for you so benefits outweigh any temporary discomfort related to increased flatulence from swallowed air.

Frequently Asked Questions
Does CPAP Make You Fart More Often?
CPAP machines can cause mild stomach bloating due to swallowed air, but they don’t directly increase how often you fart. The extra air may lead to gas buildup that your body eventually releases, but increased flatulence is usually temporary and related to aerophagia.
Why Does Using a CPAP Machine Cause Gas or Farting?
Gas or farting during CPAP use happens because of aerophagia—swallowing air unintentionally. The positive pressure from the machine can push air into your stomach, causing bloating and the need to release gas through burping or farting.
Can Mask Fit Affect How Much You Fart When Using CPAP?
Yes, a poorly fitting mask may cause you to swallow more air, increasing gas buildup and flatulence. Ensuring a proper mask fit helps reduce excess air swallowing and the digestive discomfort that sometimes leads to farting.
Does CPAP Pressure Level Influence Farting Frequency?
Higher pressure settings on a CPAP machine can increase the chance of swallowing air, which may lead to more gas and farting. Adjusting pressure levels with medical guidance can help minimize these side effects.
Is Increased Flatulence From CPAP Use Harmful?
No, increased farting due to CPAP-related aerophagia is generally harmless. It does not cause chronic digestive problems or gastrointestinal disease, and symptoms often improve as users adapt to therapy or adjust settings.
Conclusion – Does CPAP Make You Fart?
In summary: yes, using a CPAP machine can lead to swallowing extra air (aerophagia), which may increase bloating and flatulence temporarily. But it doesn’t directly cause excessive farting beyond what typical digestion produces naturally.
Most people adapt well after initial adjustment periods through proper mask fitting, pressure calibration, breathing techniques, and dietary modifications. These steps minimize uncomfortable side effects without compromising life-saving treatment benefits.
