Most bloating comes down to three things: trapped gas, water retention, or your gut overreacting to normal amounts of gas. The good news is that each of these has practical fixes, and most people can reduce bloating significantly within a few days to a week of making changes. Here’s what actually works.
Why Your Belly Bloats in the First Place
Bloating feels like pressure, fullness, or visible swelling in your abdomen. It happens when gas builds up in your digestive tract, when your body holds onto extra water, or when your gut is unusually sensitive to stretching. Some people experience all three at once.
Gas gets trapped when your intestines struggle to move it through efficiently. In studies comparing people with chronic bloating to healthy volunteers, 90% of those with sensitive guts retained gas in their intestines compared to only 20% of people without symptoms, even when both groups produced similar amounts of gas. The problem isn’t necessarily that you’re making more gas. It’s that your body is slower to clear it, particularly from the upper part of the colon and small intestine. On top of that, some people feel normal amounts of gas more intensely because the nerves in their gut have a lower threshold for discomfort.
Cut Back on High-FODMAP Foods
FODMAPs are short-chain carbohydrates that ferment rapidly in your gut, producing gas. They include fructose (in many fruits and honey), lactose (in dairy), fructans (in wheat, onions, and garlic), galactans (in beans and lentils), and sugar alcohols (in sugar-free gum and some sweeteners). Reducing these foods is one of the most effective dietary strategies for bloating, with up to 86% of people with irritable bowel syndrome reporting improvement in symptoms including bloating. In one study, 96% of patients with bloating achieved adequate relief.
You don’t need to avoid all of these permanently. A standard low-FODMAP approach involves cutting them out for two to six weeks, then reintroducing them one group at a time to identify your specific triggers. Most people find that only one or two categories cause problems. The greatest symptom control in clinical trials was achieved and maintained after just seven days on the diet.
Common high-FODMAP culprits to try eliminating first: garlic, onions, wheat-based bread, apples, pears, milk, yogurt, beans, and cauliflower. Swap these for low-FODMAP alternatives like rice, potatoes, spinach, carrots, oranges, strawberries, and lactose-free dairy.
Be Careful With Fiber
Fiber is healthy, but increasing it too fast is one of the most common causes of new bloating. Data from the OmniHeart Trial showed that switching from a typical low-fiber American diet to a higher-fiber diet increased bloating occurrence. Plant-protein sources like beans, legumes, nuts, and soy were particularly problematic because they’re rich in oligosaccharides, a type of soluble fiber that produces a lot of gas during fermentation.
If you’re adding more fiber to your diet, increase by about 3 to 5 grams per day over several weeks rather than all at once. Interestingly, the OmniHeart researchers found that replacing some of that plant protein with carbohydrate-rich foods was an effective strategy for reducing bloating. So if a new high-fiber eating plan is making you miserable, try shifting the balance toward whole grains and starchy vegetables rather than loading up on beans and lentils.
Reduce Salt Intake
Sodium drives water retention throughout your body, including your abdomen. Research from the DASH-Sodium Trial found that higher sodium intake promotes water retention and suppresses digestive efficiency, both of which contribute to bloating. High-salt diets also appear to change gut bacteria composition, reducing beneficial Lactobacillus species that help with digestion.
Most people eat far more sodium than they realize, largely from processed and restaurant foods. Cutting back to around 2,300 mg per day (roughly one teaspoon of table salt) can noticeably reduce water-retention bloating within a day or two. Check labels on canned soups, deli meats, frozen meals, bread, and condiments, which are the biggest hidden sources.
Stop Swallowing Extra Air
You naturally swallow small amounts of air when you eat, breathe, and talk. But certain habits dramatically increase the volume of air entering your gut, a condition called aerophagia. Chewing gum is a major offender. So is eating quickly, sucking on hard candies, drinking through straws, and talking while chewing.
The fix is straightforward: chew food slowly, finish one bite before taking the next, and skip the gum. If you’re a fast eater, try putting your fork down between bites. These changes won’t eliminate bloating on their own, but they remove one of the easiest-to-fix contributors. Carbonated drinks also pump gas directly into your stomach, so cutting soda and sparkling water can help.
Try Peppermint Oil Capsules
Enteric-coated peppermint oil capsules are one of the better-studied natural remedies for bloating. The enteric coating is important because it lets the capsule pass through your stomach and release in your intestines, where it relaxes smooth muscle and helps trapped gas move through. In one trial, 83% of people taking peppermint oil had marked or moderate improvement in abdominal distention compared to 29% on placebo. Another trial found that 75% of the peppermint oil group had a greater than 50% reduction in total symptom scores after four weeks, versus 38% on placebo.
Look for enteric-coated capsules containing 180 to 225 mg of peppermint oil, taken two to three times daily before meals. These are widely available over the counter. Side effects are mild but can include heartburn if the coating dissolves too early, so take them on an empty stomach with cool water rather than hot beverages.
Consider a Targeted Probiotic
Not all probiotics help with bloating, and grabbing a random bottle off the shelf is unlikely to do much. But specific strains have strong evidence. A network meta-analysis of 39 studies found that Lactobacillus plantarum 299v, Bifidobacterium bifidum MIMBb75, and the multi-strain blend VSL#3 were all significantly better than placebo at reducing bloating scores. Bacillus coagulans MTCC 5856 also ranked highly.
When shopping for a probiotic, look for one of these specific strains on the label. Generic “Lactobacillus blend” products may not contain the strains that have been tested. Give any probiotic at least four weeks before deciding whether it’s working.
Use Simethicone for Quick Relief
Simethicone (sold as Gas-X, Phazyme, and store-brand equivalents) works by breaking up gas bubbles in your stomach and intestines so they’re easier to pass. It doesn’t prevent gas from forming, but it can take the edge off when you’re already uncomfortable. The typical dose for adults is 40 to 125 mg taken up to four times daily after meals and at bedtime, with a maximum of 500 mg in 24 hours. It’s available as chewable tablets, capsules, and liquid drops, and has very few side effects because it isn’t absorbed into your bloodstream.
Move Your Body to Move the Gas
Physical movement helps your intestines push gas through and out. Even a 10 to 15 minute walk after a meal can make a noticeable difference. For more immediate relief, specific positions compress and massage your abdominal organs to help release trapped gas.
The wind-relieving pose is exactly what it sounds like: lie on your back, pull both knees toward your chest, and hold for 30 seconds to a minute. Child’s pose (kneeling with your forehead on the floor and arms extended) gently compresses your abdomen. A two-knee spinal twist, where you lie on your back and drop both bent knees to one side, stretches and massages the intestines. You can also try a simple abdominal self-massage: using the flat of your hand, rub in clockwise circles around your belly button for a few minutes. This follows the natural direction of your digestive tract and can help things move along.
When Bloating Signals Something Bigger
Occasional bloating after a big meal or a high-fiber day is normal. But certain patterns warrant a closer look. Bloating that comes with unintentional weight loss, blood in your stool, persistent vomiting, feeling full after just a few bites, or new symptoms after age 55 should be evaluated by a doctor. These can point to conditions like celiac disease, gastric outlet obstruction, or other issues that need specific treatment rather than dietary tweaks.
If your bloating is chronic and accompanied by alternating diarrhea and constipation, it’s worth getting tested for celiac disease, which is commonly missed in people initially assumed to have irritable bowel syndrome. A simple blood test can screen for it.
