Nearly 18% of people worldwide experience bloating at least once a week, making it one of the most common digestive complaints. The good news: most bloating responds well to straightforward changes in how and what you eat, and a handful of targeted remedies can speed relief when it strikes. Here’s what actually works.
What’s Happening Inside When You Bloat
Bloating has two main sources. The first is gas produced by bacteria in your colon as they ferment undigested food residues, primarily generating hydrogen, methane, and carbon dioxide. The second is how your body responds to that gas. In people who bloat frequently, the abdominal wall muscles don’t tighten the way they should when gas volume increases. Instead of contracting to hold things in place, the muscles relax, letting the belly push outward. This means bloating isn’t always about having more gas; it can also be about your body handling a normal amount of gas abnormally.
Fluid retention plays a role too. High sodium intake increases bloating in a dose-dependent way: in a controlled trial, about 35% of people on a high-sodium diet reported bloating, compared to roughly 25% on a low-sodium diet. The pattern held regardless of what else participants were eating.
Cut the Foods That Ferment Fastest
Certain carbohydrates pass through your small intestine undigested and arrive in the colon where bacteria feast on them, producing large volumes of gas quickly. These are the FODMAPs: short-chain carbohydrates found in foods like onions, garlic, wheat, beans, apples, and dairy products containing lactose. In clinical studies, eliminating high-FODMAP foods for just two weeks produced a 56% reduction in bloating severity.
A low-FODMAP approach works in three phases. You remove high-FODMAP foods for two to eight weeks, then reintroduce them one category at a time to identify your personal triggers, and finally settle into a long-term diet that avoids only the specific foods that bother you. Working with a dietitian during this process helps, since the elimination phase is intentionally restrictive and not meant to last forever.
Choose the Right Type of Fiber
Fiber is often recommended for digestion, but the type matters enormously for bloating. Short-chain, highly fermentable fibers like those in supplements containing inulin or fructooligosaccharides produce gas so rapidly that your gut can’t absorb it into the bloodstream fast enough. The result is pain, distension, and flatulence.
Psyllium husk is a better option. It’s a long-chain, moderately fermentable, soluble fiber that produces far less gas. If you’re adding fiber to your diet, start with a small dose and increase gradually over a week or two to give your gut bacteria time to adjust.
Slow Down When You Eat
Every time you swallow a mouthful of food or liquid, you also swallow air. Studies using sensors inside the esophagus show that a single 10-milliliter sip of liquid carries 8 to 32 milliliters of air into the stomach. Eating quickly, talking while chewing, drinking through straws, and chewing gum all multiply the amount of air you take in. That air has to go somewhere, and if it doesn’t come back up as a belch, it travels through your intestines and contributes to bloating.
Smaller, more frequent meals also help. A large meal stretches the stomach and slows gastric emptying, giving bacteria more time and more raw material to produce gas.
Reduce Your Sodium Intake
Salt causes your body to hold onto water, and that fluid retention can make your abdomen feel swollen and tight. In the DASH-Sodium trial, switching from high to low sodium intake reduced bloating risk by 27%, and the effect was consistent across different dietary patterns. Processed foods, restaurant meals, canned soups, and deli meats are the biggest sources of hidden sodium. Cooking more meals at home and seasoning with herbs, spices, and citrus instead of salt is one of the simplest ways to see a difference within days.
Remedies That Have Clinical Evidence
Peppermint Oil
Enteric-coated peppermint oil capsules relax the smooth muscle in your intestinal wall, helping trapped gas move through more easily. In a randomized trial of 110 people, 83% of those taking peppermint oil capsules reported less abdominal distension after one month, compared to 29% on placebo. The enteric coating is important: it prevents the capsule from dissolving in your stomach, which would cause heartburn. Take them 15 to 30 minutes before meals.
Digestive Enzyme Supplements
If beans, lentils, and certain vegetables are your main triggers, an enzyme called alpha-galactosidase (sold as Beano and similar products) can help. Your small intestine lacks the enzyme needed to break down certain complex sugars in these foods, so they pass intact to the colon where bacteria ferment them. Taking the enzyme with your first bite breaks down those sugars before they reach the colon, reducing gas production at the source.
Simethicone
Simethicone (found in Gas-X and similar products) works differently from the options above. It doesn’t prevent gas from forming. Instead, it acts as a surfactant that reduces the surface tension of gas bubbles already in your gut, causing small bubbles to merge into larger ones that are easier to pass as flatulence or belching. It’s not absorbed into your bloodstream, so side effects are minimal. It works best for acute relief rather than as a long-term strategy.
Probiotics
Specific probiotic strains have shown measurable effects on bloating in clinical trials. The strain with the longest track record is Bifidobacterium longum 35624 (previously called B. infantis), which has been studied extensively in people with irritable bowel syndrome. Several strains of Bacillus coagulans and Lactiplantibacillus plantarum 299v have also reduced bloating severity in randomized trials. The key word is “strain-specific.” A generic probiotic yogurt or supplement may not contain any of the strains that have actual evidence behind them. Check the label for the full strain name and number.
Movement That Moves Gas
Physical activity stimulates intestinal motility, helping gas travel through and out of your digestive tract rather than pooling in one segment. Even a 10 to 15 minute walk after a meal can make a noticeable difference. For more targeted relief, certain yoga poses use gentle compression of the abdomen to encourage gas release.
The wind-relieving pose is the most direct: lie on your back, bring your knees toward your chest, and gently hug your shins. As you inhale, let your knees drift slightly away from your body. As you exhale, draw them back in. The rhythmic compression and release helps trapped gas move. Child’s pose works similarly, with your torso folded over your thighs creating light pressure on your stomach. A standing forward fold, where you bend at the hips and rest your belly against your thighs, compresses the digestive organs and stimulates circulation in the area.
When Bloating Signals Something Bigger
Occasional bloating after a large or rich meal is normal. Bloating that persists for more than a week, gets progressively worse, or comes with pain that doesn’t resolve deserves medical attention. Red flags that warrant a prompt visit include unintentional weight loss, fever, vomiting, rectal bleeding, new anemia, or a sudden change in bowel habits. These symptoms can signal conditions ranging from celiac disease and ovarian cysts to more serious causes that benefit from early detection.
