Most bloating improves with a combination of dietary changes, movement, and targeted over-the-counter remedies. The right approach depends on what’s driving your symptoms, because bloating isn’t just about having too much gas. In many cases, the real issue is how your body moves gas through the digestive tract or how sensitive your gut is to normal amounts of it.
Why You Feel Bloated in the First Place
The simplest explanation, that your body is producing too much gas, is actually the least common cause. Studies comparing people with chronic bloating to healthy volunteers found no significant differences in how much gas they produced. What did differ was how their bodies handled that gas.
In one study, 90% of people with irritable bowel syndrome retained intestinal gas during testing, compared to just 20% of healthy controls. Their bodies were slower to clear gas from the small intestine and upper colon, letting it pool and stretch the gut wall. On top of that, many people with bloating have heightened sensitivity to that stretch. A modest amount of trapped gas can trigger pain and fullness that feels wildly out of proportion to what’s actually there. This is why two people can eat the same meal and only one walks away feeling like a balloon.
Understanding this helps explain why no single remedy works for everyone. If your bloating comes from eating foods that ferment quickly, dietary changes will help most. If the issue is sluggish gas transit, movement and positioning may matter more. For many people, it’s a mix of both.
Dietary Changes That Make the Biggest Difference
The low FODMAP diet is the most studied dietary approach for bloating. FODMAPs are short-chain carbohydrates found in foods like onions, garlic, wheat, beans, apples, and dairy. They ferment rapidly in the colon, pulling in water and producing gas. The diet works in three phases: an elimination phase lasting two to six weeks, a reintroduction phase where you add foods back one at a time over two to four weeks, and a long-term maintenance phase tailored to your personal triggers.
The elimination phase is not meant to be permanent. It’s deliberately restrictive so you can identify which specific foods cause problems. Most people find they react to only a few FODMAP categories, not all of them, so the reintroduction phase is where the real learning happens. Working with a dietitian makes this process significantly easier and helps you avoid unnecessary long-term restrictions.
Beyond FODMAPs, a few simpler habits can reduce bloating on their own: eating more slowly, chewing thoroughly, and limiting carbonated drinks. Swallowed air is an underrated contributor, especially if you eat quickly, chew gum, or drink through straws.
Over-the-Counter Remedies Worth Trying
Simethicone (the active ingredient in Gas-X and similar products) works by breaking up gas bubbles in the gut so they’re easier to pass. It acts locally in the digestive tract and isn’t absorbed into the bloodstream, which makes side effects rare. A systematic review found that people who took simethicone had significantly lower odds of experiencing bloating compared to those who didn’t, with more than twice the likelihood of bloating in the group that went without it.
For bloating triggered specifically by beans, lentils, and cruciferous vegetables, a digestive enzyme called alpha-galactosidase (sold as Beano) can help. These foods contain complex sugars that human enzymes can’t break down, so bacteria in your colon ferment them instead. Alpha-galactosidase breaks those sugars down before they reach the colon. In a randomized controlled trial, the enzyme significantly reduced the number of days with moderate to severe bloating and decreased flatulence compared to placebo. You take it with your first bite of the problem food for it to work.
Peppermint Oil
Enteric-coated peppermint oil capsules relax the smooth muscle of the intestinal wall, which can ease cramping and help trapped gas move along. The enteric coating is important because it prevents the capsule from dissolving in the stomach, where peppermint oil can relax the valve between the stomach and esophagus and cause heartburn. In a trial of 110 people with IBS, participants took one capsule three to four times daily, 15 to 30 minutes before meals, for one month. Side effects were minimal, with heartburn occurring only in a patient who chewed the capsule instead of swallowing it whole.
Movement and Body Position
Physical activity speeds up gas transit through the intestines. Even a 10 to 15 minute walk after eating can make a noticeable difference, particularly if your bloating tends to worsen in the evening after sitting most of the day.
For more immediate relief, specific yoga-style positions use gravity and gentle compression to help gas move. The wind-relieving pose is the most commonly recommended: lie on your back, draw one knee toward your chest, and wrap your hands around it. Lift your head gently toward your knee, hold for a few breaths, then release and repeat with the other leg. You can also draw both knees up and rock gently side to side. The key is to keep the leg that stays on the ground as straight as possible and avoid lifting your lower back off the floor. This compresses the abdomen in a way that physically encourages gas to pass.
Probiotics: Promising but Nuanced
Probiotics get a lot of attention for bloating, but the evidence is more specific than most marketing suggests. A meta-analysis looking at one of the most studied strains for gut health, Bifidobacterium infantis 35624, found that taking it alone did not significantly improve bloating. However, multi-strain probiotic formulations that included B. infantis alongside other strains did produce a meaningful reduction in bloating and abdominal distension.
This suggests that combination products are more likely to help than single-strain supplements. If you want to try probiotics, look for multi-strain formulations and give them at least four weeks before deciding whether they’re working. Results vary considerably from person to person, and a product that helps one individual may do nothing for another.
When Bloating Signals Something Else
Occasional bloating after a large meal or a high-fiber day is normal. Persistent bloating that doesn’t respond to the strategies above, or that comes with other changes, deserves medical attention. Red flags include unintentional weight loss, blood in your stool, and anemia (which might show up as unusual fatigue or pallor). These symptoms can point to conditions like celiac disease, ovarian pathology, or inflammatory bowel disease that require specific diagnosis and treatment. New, persistent bloating in someone over 50 who has never had digestive issues also warrants evaluation, since the pattern itself is the concern rather than any single accompanying symptom.
