Why Do I Fart When I Cough? (2023)

by | Updated: Sep 26, 2023

Many people experience the seemingly odd phenomenon of farting when they cough.

While it may cause a momentary sense of embarrassment or confusion, there’s actually a straightforward explanation rooted in the mechanics of the human body.

Understanding the physiological processes at play can offer clarity on why coughing sometimes leads to an unexpected release of gas.

Why Do I Fart When I Cough?

When you cough, you exert pressure on your abdominal and pelvic muscles, compressing the organs in your abdomen, including your intestines. This can force gas out of your intestines and cause you to fart. It’s a completely natural reaction and is generally nothing to worry about unless it becomes a frequent issue.

The act of farting when you cough can be attributed to a combination of factors involving physiology and the mechanics of your abdominal and pelvic muscles.

Here are some of the main causes:

  • Pressure on Abdominal Muscles: Coughing involves a forceful expulsion of air from your lungs, which puts pressure on the abdominal and pelvic muscles. This can compress the organs in the area, forcing gas out through the rectum.
  • Gas Accumulation: Throughout the day, gas naturally accumulates in your digestive system due to factors like eating, swallowing air, and the bacterial fermentation of food in the gut. Coughing can act as a trigger for the release of this accumulated gas.
  • Diaphragmatic Movement: The diaphragm plays a crucial role in both coughing and controlling the pressure systems within the thoracic and abdominal cavities. When you cough, the diaphragm contracts sharply, affecting intra-abdominal pressure and potentially leading to flatulence.
  • Relaxed Sphincter: During a coughing episode, your focus is generally on expelling air from your lungs. This distraction can sometimes lead to the temporary relaxation of the anal sphincter, allowing gas to escape more freely.
  • Underlying Medical Conditions: Conditions such as irritable bowel syndrome (IBS), chronic obstructive pulmonary disease (COPD), or even some food intolerances can exacerbate the frequency with which you fart when you cough.

Note: Understanding these factors can help demystify the experience and offer reassurance that, in most cases, it’s a natural bodily function.


Preventing flatulence when coughing involves a multi-faceted approach that tackles both the accumulation of gas and the mechanisms that release it.

Here are some strategies:

  • Control Diet: Foods high in fiber or certain carbohydrates (like beans, lentils, broccoli, and onions) can produce excess gas. You might consider reducing these foods or introducing them slowly into your diet.
  • Stay Hydrated: Drinking water can help with digestion and may reduce the occurrence of gas. Avoid carbonated drinks, as they can contribute to gas buildup.
  • Exercise Regularly: Physical activity helps regulate bowel movements and can aid in the expulsion of gas in a more controlled setting.
  • Chew Thoroughly: Eating quickly can lead to swallowing air, which may contribute to gas buildup. Take time to chew food thoroughly to aid in digestion and minimize swallowed air.
  • Avoid Straws and Gum: These can lead to swallowing more air, increasing the amount of gas that may be expelled during a cough.
  • Probiotics: These can help regulate the bacteria in your gut, which may reduce gas production. Consult a healthcare provider before starting any supplements.
  • Anti-Gas Medication: Over-the-counter medications like simethicone can help break down gas bubbles in your digestive system. Again, consult with a healthcare provider for personalized advice.
  • Mindful Breathing: Learning to control your breath can minimize the pressure exerted on your abdominal cavity when you cough, thereby reducing the chance of an accidental fart.
  • Posture: Maintaining good posture can minimize pressure on the abdominal cavity and might help in controlling the release of gas.
  • Consult a Healthcare Provider: If you find that you’re frequently passing gas when coughing, especially if accompanied by other symptoms, it might be helpful to consult a healthcare provider for a more thorough diagnosis and tailored treatment plan.

Note: By adopting these strategies, you may reduce the likelihood of experiencing flatulence when coughing.

FAQs About Farting and Coughing

Does Coughing Make You Fart More?

Yes, coughing can increase the likelihood of farting. When you cough, your diaphragm contracts forcefully and puts pressure on your abdominal and pelvic muscles.

This pressure can compress your intestines and force out gas, leading to flatulence.

What is Your Body Telling You When You Fart?

Farting is a natural bodily function that occurs when gas accumulates in the digestive system and is expelled through the rectum.

It indicates that your body is digesting food and producing gas as a by-product. However, excessive or painful flatulence can be a sign of digestive issues or food intolerances.

How Can I Stop Farting So Much?

Reducing flatulence involves changes in diet, hydration, and lifestyle. Foods high in fiber or certain carbohydrates can produce more gas; reducing them may help.

Exercise aids in regulating bowel movements, and drinking water can assist digestion.

Anti-gas medication and probiotics may also be beneficial. Consult a healthcare provider for personalized advice.

Can You Cough and Fart at the Same Time?

Yes, you can cough and fart at the same time. When you cough, your diaphragm and abdominal muscles contract forcefully, increasing pressure within the abdominal cavity.

If gas is present in your intestines, this increased pressure can cause you to expel it, leading to simultaneous coughing and farting.

It’s a natural physiological response and generally not a cause for concern.

When is Gas a Problem?

Gas becomes a problem when it is frequent, painful, or accompanied by other symptoms like abdominal discomfort, bloating, or a noticeable change in bowel habits.

Excessive gas could indicate underlying conditions such as irritable bowel syndrome (IBS) or food intolerances.

If you experience persistent issues, consult a healthcare provider for diagnosis and treatment.

Final Thoughts

Farting when coughing is largely a natural occurrence based on the pressure exerted on the abdominal and pelvic muscles.

Though it might feel awkward, it is generally nothing to worry about.

However, if you experience persistent or uncomfortable symptoms, it may be wise to consult a healthcare professional to rule out any underlying issues.
