The fastest relief for bloating and gas depends on what’s causing it. For immediate discomfort, over-the-counter gas relief products and peppermint oil capsules can help. For recurring bloating, dietary changes, eating habits, and physical activity make the biggest long-term difference. Here’s what actually works, starting with the quickest fixes.
Quick Relief: Gas-Reducing Products
Simethicone, the active ingredient in products like Gas-X, works by reducing the surface tension of gas bubbles trapped in your stomach and intestines. This lets smaller bubbles merge into larger ones that are easier for your body to expel through burping or passing gas. It’s not absorbed into your bloodstream, so side effects are essentially nonexistent. That said, clinical evidence for its effectiveness is surprisingly thin. It’s widely used based on common consensus rather than strong trial data, but many people find it helpful for short-term relief.
If your gas tends to flare after eating beans, lentils, broccoli, or other plant-heavy meals, an enzyme supplement containing alpha-galactosidase (sold as Beano) can help. This enzyme breaks down specific sugars called raffinose and stachyose that your body can’t digest on its own. When those sugars reach your large intestine intact, bacteria ferment them and produce gas. The key is timing: you need to take the enzyme with your first bite of food, not after symptoms start.
Peppermint Oil for Bloating
Enteric-coated peppermint oil capsules relax the smooth muscle lining your digestive tract, which can ease the cramping and pressure that make bloating feel so uncomfortable. The enteric coating is important because it prevents the capsule from dissolving in your stomach (which can cause heartburn) and instead releases it in your intestines where it’s needed. The NHS recommends one capsule three times a day for adults, increasing to two capsules three times a day if needed. This is one of the better-studied natural options for digestive discomfort, particularly for people with irritable bowel syndrome.
Eating Habits That Reduce Swallowed Air
A surprising amount of bloating comes not from food itself but from swallowing excess air. This is called aerophagia, and it’s more common than most people realize. Eating too fast, talking while eating, and chewing gum are the main culprits. Stress and anxiety can also trigger a pattern of frequent air gulping without you noticing. In severe cases, people with aerophagia belch up to 120 times an hour, compared to the normal rate of about 10.
The fix is straightforward: chew slowly, finish one bite before taking the next, and avoid talking with food in your mouth. Drinking through straws and sipping carbonated beverages also force extra air into your stomach. These changes sound minor, but for people whose bloating is primarily air-driven, they can eliminate the problem entirely.
The Low FODMAP Diet
FODMAPs are a group of short-chain carbohydrates that ferment rapidly in your gut, pulling in water and producing gas. They’re found in a wide range of foods: garlic, onions, wheat, apples, milk, honey, and many legumes. A low FODMAP diet temporarily removes these foods, then reintroduces them one at a time so you can identify your personal triggers.
Research from Johns Hopkins Medicine found that a low FODMAP diet reduces symptoms in up to 86% of people. That’s a remarkable success rate, but the diet is restrictive and best done with guidance from a dietitian. It’s not meant to be permanent. The goal is the reintroduction phase, where you learn which specific foods cause your symptoms and at what portion sizes. Most people find they can tolerate many FODMAPs in moderate amounts and only need to avoid a few specific ones.
Probiotics That Target Gas
Not all probiotics help with bloating, and “probiotic” on a label doesn’t mean much without knowing the specific strain. A systematic review published in The Lancet’s eClinicalMedicine identified several strains with clinical evidence for reducing IBS-related bloating and abdominal pain. Bifidobacterium infantis 35624 showed significant improvement in bloating scores across multiple trials, with medium doses performing better than both low and high doses. Bifidobacterium animalis DN-173010 (the strain in some fermented dairy drinks) also demonstrated measurable reductions in bloating compared to placebo.
The catch is that probiotic effects are strain-specific. A product containing a different strain of Bifidobacterium, even a closely related one, may not have the same benefit. Look for products that list the full strain name and number on the label, not just the species. Give any probiotic at least four weeks before deciding whether it’s working.
Walking After Meals
One of the simplest and most effective things you can do is take a short walk after eating. Light movement stimulates peristalsis, the wavelike muscle contractions that push food, stool, and gas through your digestive tract. Walking helps gas move through your system faster and reduces the amount of time it spends shifting around in your intestines, which is what causes that uncomfortable bloated sensation. Even 10 to 15 minutes of gentle walking can make a noticeable difference, and it costs nothing.
Fiber: Helpful or Harmful
Fiber is essential for healthy digestion, but increasing it too quickly is one of the most common causes of bloating. Your gut bacteria need time to adjust to higher fiber loads. If you’re adding more fruits, vegetables, beans, or whole grains to your diet, ramp up gradually over two to three weeks rather than making a dramatic overnight change.
The type of fiber matters too. Highly fermentable fibers, like those in beans, chicory root, and inulin-based supplements, produce more gas than less fermentable options like psyllium husk or oat fiber. If you’re prone to bloating, start with these gentler sources and increase slowly. Drinking plenty of water alongside fiber also helps it move through your system rather than sitting and fermenting.
When Bloating Signals Something More
Occasional bloating after a large meal or a high-fiber day is normal. But bloating that gets progressively worse, lasts more than a week, or comes with persistent pain deserves medical attention. The Cleveland Clinic flags several symptoms that should prompt a visit: fever, vomiting, bleeding, unintentional weight loss, anemia, or significant changes in bowel habits like new diarrhea or constipation. These can point to conditions ranging from food intolerances and small intestinal bacterial overgrowth to celiac disease or ovarian issues, all of which are treatable once identified.
