Most gas can be treated at home with a combination of simple habit changes, over-the-counter remedies, and dietary adjustments. The average person passes gas at least 14 times a day, so the goal isn’t to eliminate it entirely but to reduce discomfort, bloating, and excessive frequency. Here’s what actually works.
Reduce Swallowed Air First
A surprising amount of gas in your digestive tract comes from air you swallow throughout the day. Before reaching for any remedy, it’s worth checking whether your everyday habits are part of the problem. Common culprits include eating too fast, talking while eating, chewing gum, sucking on hard candy, drinking through straws, and drinking carbonated beverages. Smoking also increases the amount of air you swallow.
These are easy fixes that can make a noticeable difference within a day or two. Slowing down at meals and putting your fork down between bites gives you less opportunity to gulp air. If you’re a regular gum chewer or seltzer drinker, cutting back for a week is a simple way to test whether swallowed air is driving your symptoms.
Over-the-Counter Gas Relief
Simethicone is the most widely available gas medication and the active ingredient in products like Gas-X and Mylanta Gas. It works as a surfactant, meaning it reduces the surface tension of gas bubbles in your digestive tract so they merge together into larger bubbles. Those larger bubbles are easier to expel through belching or flatulence. Simethicone does not reduce how much gas your body produces. It just helps you pass what’s already there more comfortably.
Another option targets gas at its source. Products containing the enzyme alpha-galactosidase (sold as Beano) break down the complex carbohydrates in foods like beans, broccoli, and cabbage before they reach your colon, where bacteria would otherwise ferment them and produce gas. You take it with your first bite of a gas-producing food, not after symptoms start. It won’t help with gas caused by dairy (that requires lactase) or gas from swallowed air.
Activated charcoal is sometimes marketed for gas relief, but the evidence is mixed. While it’s proven effective in hospital settings for certain poisoning cases, its ability to reduce everyday gas and bloating hasn’t been reliably demonstrated. It can also interfere with nutrient absorption, reduce the effectiveness of other medications, and cause constipation with regular use. These supplements aren’t regulated by the FDA, so quality varies.
Peppermint Oil for Bloating and Spasms
Peppermint oil has stronger clinical evidence behind it than most natural remedies. Multiple controlled trials have shown it reduces bloating, flatulence, and abdominal pain, particularly in people with irritable bowel syndrome. In one trial, 79% of people taking peppermint oil saw meaningful improvement in flatulence, compared to just 22.5% on placebo. Another study found that 75% of participants had more than a 50% reduction in total symptom scores after four weeks.
Enteric-coated peppermint oil capsules are the form used in most studies. The coating prevents the oil from releasing in the stomach (where it can cause heartburn) and delivers it to the intestines, where it relaxes smooth muscle and eases trapped gas. Peppermint tea is gentler and may provide mild relief, but it delivers far less of the active compound than capsules.
Dietary Changes That Lower Gas Production
Your gut bacteria produce gas when they ferment carbohydrates that your small intestine didn’t fully absorb. Some foods are notorious for this: beans, lentils, onions, garlic, wheat, certain fruits, and cruciferous vegetables like broccoli and Brussels sprouts. Dairy causes gas specifically in people who don’t produce enough lactase to digest lactose.
If gas is a persistent problem, a low-FODMAP diet is the most structured approach. FODMAPs are a group of fermentable carbohydrates found in a wide range of foods. The diet works in two phases: an elimination phase lasting two to six weeks, during which you remove high-FODMAP foods, followed by a reintroduction phase where you add foods back one at a time to identify your personal triggers. It can take the full elimination period before symptoms fully subside, so this isn’t a quick fix. Working with a dietitian helps you avoid unnecessary restrictions.
For a less formal approach, keep a food diary for two weeks. Write down what you eat and when symptoms flare. Patterns usually emerge quickly: maybe it’s the lentil soup, the apple you eat at 3 p.m., or the milk in your coffee.
Physical Movement and Positioning
When gas feels trapped and painful, certain body positions can help move it through your system. A gentle walk after meals stimulates the muscles in your intestines and helps gas pass naturally.
Specific yoga poses are particularly effective for releasing trapped gas. The wind-relieving pose (lying on your back and pulling one or both knees to your chest) works by compressing and then releasing the abdomen, which helps your intestines move gas along. Kneeling and sitting back on your heels stimulates the stomach area and can relieve bloating. Lying face-down and reaching back to grab your ankles in a bow position increases blood flow to your digestive organs. Even five minutes of these positions can provide noticeable relief during an acute episode.
What About Probiotics?
Probiotics get a lot of attention for digestive health, but the evidence for gas specifically is underwhelming. An international consensus review found that while certain probiotics can help reduce bloating and abdominal distension, the probiotics tested so far do not reliably reduce flatulence. The distinction matters: bloating (the sensation of fullness and pressure) and flatulence (actually passing gas) appear to respond to different interventions.
If bloating is your main complaint rather than excessive gas, a multi-strain probiotic may be worth trying for a few weeks. Single-strain products containing Bifidobacterium infantis alone did not improve symptoms in pooled study data, but combination products containing that strain alongside others did reduce pain and bloating.
Signs Your Gas Needs Medical Attention
Gas itself is almost never dangerous, but persistent or severe gas alongside other symptoms can signal a digestive condition that needs treatment. Pay attention if your gas comes with fever, nausea and vomiting, unexplained weight loss, chronic or sudden-onset diarrhea, rectal bleeding, or stools that are black, bloody, or unusually greasy and foul-smelling. Severe abdominal pain that doesn’t seem connected to meals, or any chest pain, also warrants a visit to your healthcare provider rather than continued self-treatment.
