How to Get Rid of Gas on Your Stomach Fast

Standing up and walking around is the single fastest way to move trapped gas through your digestive tract, and research backs this up convincingly. Beyond that, a handful of other strategies, from applying warmth to your belly to sipping peppermint tea, can ease the pressure within minutes to an hour. The trick is knowing which remedies actually speed gas along versus which just mask the discomfort, because some popular fixes can quietly make things worse.

Stand Up and Move Around

If you’re lying on the couch when gas pain hits, the simplest thing you can do is get vertical. A study published in Gut found that intestinal gas clearance was dramatically better in an upright position compared to lying down. After 60 minutes, participants cleared about 72% of infused gas while upright versus only 49% while lying flat, and the amount of gas retained in the gut was almost negligible when standing compared to substantial retention when supine.¹ Gravity helps gas rise through the tract, and the natural contractions of the intestines work more efficiently when you’re not compressed against a mattress or cushion.

A gentle walk takes this a step further. You don’t need to jog or do anything strenuous. Even a slow stroll around the block engages your abdominal muscles in a rhythmic way that helps push gas toward the exit. Many people instinctively pace when they feel bloated, and their instinct is backed by the physics of how the gut moves gas. If walking isn’t an option, simply sitting upright with good posture is still a meaningful improvement over lying down.

Apply Warmth to Your Belly

Placing a warm compress, heating pad, or hot water bottle on your abdomen is a time-honored remedy, and there’s a physiological reason it works. A study on heat-and-steam-generating sheets found that applying warmth to the abdomen increased peripheral blood flow, shifted the nervous system toward parasympathetic dominance (the “rest and digest” mode), and boosted gastric motility.² In plain terms, warmth relaxes the muscles of the gut wall and encourages the digestive system to keep things moving rather than clenching around a pocket of gas.

The practical appeal is obvious: you can do this immediately with whatever you have. A damp towel microwaved for 30 seconds, a rice-filled sock, or a standard heating pad all work. Aim for comfortably warm rather than hot, and drape it over your midsection while sitting upright if possible, combining the benefits of posture and heat at once. Most people feel at least partial relief within 15 to 20 minutes.

Peppermint, Fennel, and Ginger

These three herbs show up in nearly every folk tradition for stomach discomfort, and all three have laboratory evidence supporting their effects on the gut, though through different mechanisms.

Peppermint oil acts as a smooth muscle relaxant. Research shows it blocks calcium channels in the intestinal wall, which is the same basic mechanism some prescription antispasmodic drugs use. Studies in both animal tissue and human colon samples confirm that menthol, peppermint’s active compound, directly inhibits the contractions of circular smooth muscle.³ When the gut wall relaxes, trapped gas can pass through more easily instead of building up behind a spasm. Peppermint tea is the most accessible form. Enteric-coated peppermint oil capsules, which dissolve in the intestine rather than the stomach, are another option if you deal with this regularly.

Fennel tea works somewhat differently. A recent study found that fennel relaxes the upper regions of the stomach (the fundus and corpus) while simultaneously increasing the strength of contractions in the lower region (the antrum).⁴ That combination is useful: the upper stomach relaxes enough to let gas move, while the lower stomach contracts more forcefully to push contents downward into the intestine. Steeping crushed fennel seeds in hot water for five to ten minutes gives you a tea that many people find soothing within the first cup.

Ginger has a long reputation for settling the stomach, and animal research suggests it may speed gastric emptying. In rats with chemically delayed stomach emptying, ginger extract reversed the delay at moderate and higher doses.⁵ Human evidence for ginger specifically targeting gas is thinner than for peppermint, but it’s widely considered safe and may help if your gas is tied to sluggish digestion. Fresh ginger sliced into hot water or chewed raw is the fastest route.

Abdominal Self-Massage

Gently massaging your abdomen can physically coax gas through the intestines. A clinical trial found that patients who received abdominal massage after a colonoscopy (a procedure that pumps air into the colon) had their bloating relieved within 15 minutes.⁶ That’s a more extreme starting point than everyday bloating, which suggests the technique should work at least as well for garden-variety trapped gas.

The standard approach is to follow the path of the colon. Start on your lower right side near the hip bone, press gently upward toward the ribs, across the upper abdomen from right to left, then down the left side. Use firm but comfortable pressure with your fingertips or the flat of your palm. Repeat for a few minutes. You’re essentially nudging gas along the same route it would travel naturally, just faster. Combining this with lying on your left side can help, since the anatomy of the colon means gas in the descending colon has an easier time reaching the rectum in that position.

Over-the-Counter Enzyme Supplements

If your gas comes from specific foods, particularly beans, lentils, broccoli, or other high-fiber plant foods, enzyme supplements taken with the meal can reduce gas before it starts. The most studied is alpha-galactosidase, sold under brand names like Beano. This enzyme breaks down the complex sugars (oligosaccharides) that your body can’t digest on its own, which would otherwise arrive intact in your colon and get fermented by bacteria into gas.

A double-blind crossover study found that alpha-galactosidase significantly reduced flatulence events compared to placebo over a six-hour period after a gas-producing meal, though it didn’t significantly reduce bloating or pain in that particular trial.⁷ A separate study tested different doses and found that a higher dose (1,200 GalU) significantly reduced both hydrogen production in the breath (a direct measure of bacterial fermentation) and the severity of flatulence, along with overall symptom scores.⁸ The catch is that these need to be taken with or just before the meal, not after you’re already bloated. They’re preventive, not a rescue remedy.

Simethicone (sold as Gas-X and similar brands) works differently. It doesn’t prevent gas formation; instead, it breaks large gas bubbles into smaller ones, which theoretically makes them easier to pass. It’s generally considered safe and fast-acting, though the clinical evidence for meaningful symptom relief is mixed. For many people, simethicone provides modest comfort rather than dramatic relief.

Why Baking Soda Can Backfire

Dissolving baking soda (sodium bicarbonate) in water is a common home remedy for stomach discomfort, and it does neutralize stomach acid. But here’s the problem: that neutralization reaction literally creates carbon dioxide gas. A study in Gastroenterology examined what happens when sodium bicarbonate meets hydrochloric acid (the acid in your stomach) and found that while the chemical reaction itself is instant, the CO₂ produced dissolves into the liquid and is only slowly released into gas form.⁹ That slow release means you get a prolonged period of additional gas generation right in your stomach. If your problem is already too much gas, adding more is counterproductive. People who drink baking soda for bloating often end up more bloated and belchy in the short term, even if the acid neutralization provides some relief from heartburn.

Carbonated Drinks Are Part of the Problem

It’s worth calling out a related misconception. Some people reach for sparkling water or ginger ale when they feel gassy, thinking the bubbles will help them burp and feel better. You might get an initial belch, but you’re also pumping more gas into your stomach than you release. Research using MRI to track gastric contents showed that a carbonated drink produced significantly greater total stomach volumes compared to non-carbonated beverages and caused more gastric distress.¹⁰ The rate at which your stomach clears gas was the same regardless of the drink, so the extra gas from carbonation just sits there longer. If you’re trying to get rid of gas fast, flat water, herbal tea, or warm water is a better call.

Understanding Where the Gas Comes From

Knowing the source of your gas helps you pick the right fix. Gas in the stomach and upper digestive tract usually comes from swallowed air, a condition doctors call aerophagia. This is surprisingly common and can become chronic: people swallow large quantities of air that accumulates in the gastrointestinal tract and causes bloating and distention.¹¹ Eating quickly, talking while chewing, drinking through straws, chewing gum, and anxiety-driven mouth breathing all increase air swallowing. The resulting discomfort is usually felt high in the abdomen or behind the breastbone and is relieved by belching.

Gas in the lower digestive tract, by contrast, is produced by bacteria fermenting carbohydrates that your small intestine couldn’t absorb. Certain short-chain carbohydrates known as FODMAPs are especially efficient at generating gas. A controlled study showed that a high-FODMAP diet produced roughly four times as much hydrogen gas in healthy volunteers and about four times as much in people with irritable bowel syndrome compared to a low-FODMAP diet.¹² Common high-FODMAP foods include onions, garlic, wheat, certain fruits like apples and pears, and legumes. If your gas is consistently worse after meals and involves lower abdominal cramping and flatulence, reducing these foods is one of the most effective longer-term strategies.¹³

Activated Charcoal and Its Limits

Activated charcoal shows up in many “detox” products and is sometimes recommended for gas. The logic is straightforward: activated charcoal has an enormous surface area and adsorbs (binds to its surface) a wide range of chemicals in the gastrointestinal tract.¹⁴ The idea is that it might trap gas or gas-producing byproducts. In practice, results are inconsistent. Some small studies show modest reductions in bloating; others show no benefit over placebo. There’s also a practical downside: activated charcoal can bind to medications you’ve taken, reducing their effectiveness. If you’re on any prescription drugs, this is a meaningful risk. It can also cause constipation, which tends to make gas worse rather than better.

When the Bloating Doesn’t Go Away

Occasional gas after a big meal or a specific food trigger is normal. But if you feel bloated most days regardless of what you eat, or if the physical distention of your abdomen seems out of proportion to how much gas you think is there, something else may be going on.

One possibility is abdominophrenic dyssynergia, a coordination problem between the diaphragm and abdominal wall. In this condition, the diaphragm contracts downward while the abdominal muscles relax outward, producing visible distention that looks like extreme bloating but may involve relatively normal amounts of gas. It’s essentially a muscular misfiring rather than an overproduction of gas, and it’s been linked to visceral hypersensitivity, where the gut overreacts to normal levels of stretch and pressure.¹⁵ Biofeedback therapy, which teaches patients to consciously control those muscle groups, has shown promise in treating this.

Another possibility is small intestinal bacterial overgrowth, or SIBO, where bacteria that normally belong in the colon colonize the small intestine. This produces gas higher up in the digestive tract than usual, often leading to bloating soon after eating. Prevalence estimates range widely, from about 2.5% to 22% depending on the population studied, and it becomes more common with age and in people with other digestive conditions.¹⁶ SIBO is usually diagnosed with a breath test and treated with targeted antibiotics.

There’s also emerging research into how the gut’s reflex systems handle gas transit. In healthy people, the intestines have feedback mechanisms that adjust gas movement in response to what’s happening downstream. A study found that when healthy subjects received a stimulus in the rectum, their intestines adapted and reduced gas retention. People with chronic bloating, however, lacked this reflex entirely: their gas retention remained equally high with or without the stimulus, and they retained significantly more gas overall than the healthy group.¹⁷ This suggests that for some chronic sufferers, the problem isn’t how much gas is produced but how poorly the intestines move it along. That distinction matters because it shifts the treatment focus from diet changes toward therapies that improve gut motility.

Yoga Poses That Target Trapped Gas

Specific body positions can help release gas by compressing or stretching the abdomen in ways that encourage gas to move. The aptly named “wind-relieving pose” (lying on your back and pulling one or both knees into your chest) gently compresses the ascending and descending colon. A supine spinal twist, where you lie on your back and drop both knees to one side, stretches the abdominal muscles and can shift gas pockets. The child’s pose, kneeling with your torso folded forward over your thighs, puts gentle pressure on the entire abdomen.

These aren’t backed by the same kind of controlled trial data as some of the other remedies discussed here, but the mechanical logic is sound, and they combine two things that do have evidence: physical compression of the abdomen and changes in body position that affect gas transit. They’re also free, available immediately, and unlikely to cause any harm. If you’re at home and uncomfortable, cycling through a few of these positions for five to ten minutes is a reasonable first move alongside getting upright and applying warmth.
