Why Farting Is Healthy: The Surprising Benefits of Flatulence

Farting is a completely normal—and necessary—digestive process. Gas is created as gut bacteria digest the food we eat, or as a result of swallowing air (aerophagia), and releasing it is a normal part of keeping our digestive systems comfortable and balanced. Most people pass gas as many as 23 times a day, but diet, activity levels, and overall gut health can influence how often it happens. Despite how routine it is, many people feel embarrassed by flatulence; some even endeavor to hold it in. Doing so can lead to increased abdominal pressure and belly distension, making digestion feel more uncomfortable. Passing gas can be an effective way to feel better while helping your digestive system function smoothly.

1. Farting May Reduce Bloating

Gas buildup is a main cause of that “tight pants” feeling in the abdomen. “Your abdomen is a confined, closed space. When gas builds up, it’s exactly like blowing up a balloon inside a small box. That tight feeling is a literal distension of your… gut,” explains Pornchai Leelasinjaroen, MD, a gastroenterologist at Gastro Health in Kennewick, Washington.

That pressure builds in the digestive tract, leading to uncomfortable bloating that often worsens as the day goes on. Passing gas allows some of the trapped air to escape, reducing pressure on the intestines and can sometimes offer almost “instant relief,” says Supriya Rao, MD, a gastroenterologist and a spokesperson for the American Gastroenterological Association.

2. Gas Can Be a Potential Warning Sign

Changes in how flatulent you are can also serve as early clues about what’s happening in your gut, including food intolerances or chronic health issues. “It’s the ‘canary in the coal mine’ telling you that [something] has shifted,” says Dr. Leelasinjaroen.

Pay attention to these phenomena:

• Swift transit: If things are moving too fast, you may have symptoms such as gas accompanied by diarrhea. This is often due to malabsorption issues tied to celiac disease, lactose intolerance, or fructose intolerance.
• Slow transit: When your intestines move food through your gut too slowly, it leads to constipation. This allows for more fermentation and way more gas. Irritable bowel syndrome with constipation (IBS-C), an underactive thyroid (hypothyroidism), or even undiagnosed diabetes can be the cause.
• Diet: Gas can crop up if you overdo it on fiber or fiber supplements. Other foods, such as beans, cruciferous vegetables, and fizzy drinks can also increase flatulence.

People with gluten sensitivity or small intestinal bacterial overgrowth (SIBO) may notice extra gas and bloating. “Increased gas, bloating, or stronger odors can be the first signs something isn’t quite right,” says Dr. Rao. Paying attention to these changes can help you identify potential issues.

3. Flatulence Can Lead to Instant Stress Relief

Trapped gas doesn’t just affect the gut, it can influence how the entire body feels. “When your abdomen feels tight or pressured, it may trigger your body’s stress response and make everything feel worse,” Rao says. If you have irritable bowel syndrome (IBS), you can experience unwelcome bloating and gas. “You might have a normal amount, but your brain interprets it as painful or excessive,” says Dr. Leelasinjaroen.

Passing wind may sometimes alleviate that feeling of stress, bringing you back to a “rest and digest” state by engaging the parasympathetic nervous system. You may feel your body relax and shift back to a calmer, more settled space, Rao says. It’s a small reminder that digestive health and stress regulation are closely connected.

4. It Can Be a Sign of Healthy Gut Function

Gas is a natural by-product of gut bacteria breaking down fiber and other nutrients, which means farting is part of normal GI function. The trillions of bacteria living in the gut thrive on a varied, fiber-rich diet, and fermentation is part of how they function. “Gas is a by-product of your gut bacteria fermenting fiber and nutrients, so it’s often a sign that your microbiome is active and alive, which is a good thing,” says Dr. Leelasinjaroen.

Track your bowel movements to get a fuller picture of gut health. “Ideally, we wish to see regular bowel movements that fall around 3 to 4 on the Bristol Stool Chart, which is a better indicator [than gas] of a healthy microbiome,” says Rao. If gas shows up alongside a noticeable change in bowel habits, or begins to interfere with daily life, check in with a gastroenterologist to rule out an underlying issue.

The Takeaway: Farting is a normal and necessary part of digestion, and most people pass gas multiple times a day. Flatulence helps us relieve bloating and the physical discomfort of trapped gas. Sudden shifts in your body’s production of gas—in frequency, odor, or discomfort levels—can warn of food intolerances, motility issues, or conditions like small intestinal bacterial overgrowth (SIBO). If you have recurring or disruptive symptoms related to passing gas, check in with your healthcare provider.
