Flatulence is a biological necessity. It's just air. Specifically, it's a mix of nitrogen, hydrogen, carbon dioxide, methane, and oxygen that has been trapped in the digestive tract and needs an exit strategy. While most people are trying to figure out how to stop it, there are plenty of times—whether it’s for medical relief from bloating or just because you’re curious about how your body works—where you actually want to know how to make a fart come out.
It isn't always about what you just ate. Sometimes it's about physics.
Honestly, the "how" is divided into two camps: physiological production and physical manipulation. You're either making more gas in the lab of your gut, or you're using movement to help the gas that’s already there find the door. Most adults pass gas between 13 and 21 times a day. If you feel like you're under that average and feeling the pressure, your body is essentially holding onto a pressurized balloon that needs a release valve.

Why the Gas Gets Stuck in the First Place
Your intestines are basically a giant, winding tube. If you've ever tried to get a bubble out of a garden hose, you know it doesn't always just slide through. Sometimes it gets caught in the "kinks" or turns of the colon, known as the splenic and hepatic flexures.
This is where the discomfort starts.
Gastroenterologists often point to motility—the way your muscles move food through the pipe—as the main culprit for why gas stays trapped. If your motility is slow, the gas just sits there. You feel heavy. You feel "puffy." To get things moving, you have to understand that gas production starts way up in the mouth with aerophagia (swallowing air) and ends with the fermentation of carbohydrates by bacteria in the large intestine.
Dietary Tweaks for Natural Production
If you’re looking to increase gas production through diet, you have to look at FODMAPs. This stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. Basically, these are short-chain carbs that the small intestine doesn't absorb well. Instead of being digested, they travel down to the colon where your gut bacteria have a literal party.
They ferment. They bubble. They release gas.
- Beans and Legumes: These are the classics for a reason. They contain raffinose, a complex sugar that humans lack the enzyme to break down.
- Cruciferous Veggies: Broccoli, Brussels sprouts, and cabbage contain both raffinose and high levels of sulfur. The sulfur doesn't necessarily make more gas, but it makes it smell like, well, you know.
- Fructose and Sorbitol: Found in fruits like pears and apples, or artificial sweeteners. These are notorious for drawing water into the gut and creating rapid fermentation.
It’s kinda fascinating how specific the body is about this. If you eat a steak, you probably won't get much gas because protein is mostly absorbed before it hits the "fermentation zone." But throw in a side of onions? That's a different story. Onions contain fructans, and for many people, fructans are the primary trigger for a noisy stomach.
Using Movement to Force the Issue
Sometimes the gas is already there, but it's stuck. You can’t just wait for it. You need to change the geometry of your torso.
Yoga practitioners have known this for centuries. There is literally a pose called Pawanmuktasana, which translates directly to "Wind-Relieving Pose." It’s not a joke. It works by compressing the ascending and descending colon, which physically pushes the gas bubbles toward the rectum.
To do this effectively, you lie on your back and pull your knees to your chest. You’re basically turning your body into a human nutcracker for your own intestines. You can also try the "Child's Pose" or a deep squat. Squatting is actually the natural human position for elimination; it straightens the anorectal angle. When you sit on a standard chair or toilet, that angle is kinked. By squatting, you’re literally opening the highway.
Walking helps too. It’s the simplest "how to make a fart" hack there is. Gravity and the rhythmic movement of your legs massage the internal organs. This is why many people find they have to go to the bathroom shortly after starting a light jog or a brisk walk.
The Role of Swallowed Air
About 50% of the gas in your system isn't from fermentation at all. It’s from your mouth.

When you drink through a straw, chew gum, or talk rapidly while eating, you’re gulping down nitrogen and oxygen. This is aerophagia. If you want to increase the volume of gas in your stomach, carbonated beverages are the fast track. The "fizz" in soda or sparkling water is carbon dioxide gas. Once it’s in your stomach, it has two choices: it comes back up as a burp, or it travels the long way down.
If you lay on your left side after drinking something carbonated, you’re positioning the exit of the stomach (the pylorus) in a way that allows gas to move more easily into the small intestine. This is a neat little trick of anatomy.
When Should You Be Worried?
Look, while we're talking about how to make a fart happen, we have to talk about when it's a problem. Gas is normal. Pain is a signal.
If you are trying to pass gas because you have sharp, stabbing pains that don't go away, or if you're experiencing "pencil-thin" stools and chronic constipation, it’s not just a gas bubble. It could be an obstruction or an underlying issue like SIBO (Small Intestinal Bacterial Overgrowth).
According to research from the Mayo Clinic, most "gas" pain is actually just hypersensitivity to normal amounts of pressure. Some people have what's called visceral hypersensitivity—their nerves in the gut are just louder than everyone else's. What feels like a "giant gas bubble" to them might be a tiny puff of air that their brain is over-interpreting as a crisis.
Medical Aids and Fast Relief
If the natural methods aren't cutting it, there are over-the-counter options. Simethicone is the most common. It doesn't actually "create" or "remove" gas. Instead, it acts as an anti-foaming agent.
Imagine a bunch of tiny, stubborn bubbles that won't move. Simethicone breaks the surface tension of those bubbles, merging them into one large bubble that is much easier for your body to pass. It's like turning a hundred tiny pebbles into one easy-to-roll stone.
On the flip side, if you're trying to stop the smell while still letting the gas flow, internal deodorizers like bismuth subsalicylate can help. But that’s usually the opposite of what someone looking to "make a fart" is after.
Quick Actions to Stimulate Gas Release
If you need a result in the next ten minutes, follow this sequence:
- Drink a glass of warm water. Warmth can help relax the smooth muscles of the gut.
- The "Wind-Relieving" Pose. Lie on your back, hug your right knee to your chest for 30 seconds, then the left, then both.
- Self-Massage. Start at the lower right side of your abdomen (where the large intestine begins), move up to the ribs, across the middle, and down the left side. You are following the path of the colon.
- Deep Squat. Hold a deep squat for 60 seconds. Use a stool or the edge of a couch for balance if you need to.
Final Insights on Gut Mechanics
Getting your digestive system to "release" is often more about relaxation than force. Straining can actually cause the pelvic floor muscles to tighten, which seals the exit. It's a bit of a paradox: the more you "try" to force it, the harder it might be.
Focus on diaphragmatic breathing. When you breathe deeply into your belly, your diaphragm drops down and creates internal pressure that gently nudges the intestines. It’s a natural, internal pump.
If you've tried the movements and the dietary triggers and nothing is happening, your body might just not have any gas to give at the moment. But given the average human produces about 500 to 2,000 mL of gas daily, you usually won't have to wait long.
To keep your system moving long-term, prioritize fiber and hydration. Fiber provides the bulk that gives the muscles something to grip, while water ensures that bulk doesn't turn into a stationary brick. If you're looking for immediate relief right now, get on the floor, pull your knees to your chest, and let physics do the heavy lifting.
Next Steps for Gut Comfort
To manage your digestive health more effectively, start tracking which foods cause the most "pressure" in your system. Use a simple journal for three days, noting when you feel bloated and what you ate four to six hours prior. This "lag time" is usually how long it takes for food to hit the fermentation stage in the large intestine. Additionally, incorporate two minutes of abdominal stretching every morning to keep your motility high and prevent gas from becoming trapped in the first place.
