How Do You Stop Bloating? Proven Tips That Work

Bloating responds to a combination of dietary adjustments, physical movement, and targeted supplements, though the right mix depends on what’s driving your symptoms. For some people, reducing certain fermentable carbohydrates brings relief within days. For others, the problem has more to do with how their abdominal muscles and diaphragm respond to a normal amount of gut gas. The distinction matters because a strategy that works brilliantly for one type of bloating can be useless for another. Here’s what the research actually supports.

Two Kinds of Bloating, Two Different Problems

Before you can fix bloating, it helps to know that the word covers two distinct experiences. One is the subjective feeling of pressure or fullness in your abdomen, sometimes without any visible change. The other is measurable abdominal distension, where your belly physically pushes outward. They often overlap, but not always. The feeling of bloating appears to stem from heightened sensitivity in the gut’s nerve endings, while visible distension involves an involuntary muscular reflex: the diaphragm contracts downward and the abdominal wall relaxes outward, a pattern researchers call abdominophrenic dyssynergia.¹ Knowing which type dominates your experience can steer you toward the interventions most likely to help.

Adjust What You Eat

Diet is the first lever most people can pull, and it has the strongest evidence behind it. Certain short-chain carbohydrates, grouped under the acronym FODMAPs (fermentable oligosaccharides, disaccharides, monosaccharides, and polyols), are rapidly fermented by gut bacteria, producing gas that stretches the intestinal walls. A structured low-FODMAP elimination diet consistently reduces bloating, pain, and quality-of-life scores in people with irritable bowel syndrome, and when compared against other dietary approaches in pooled analyses, it comes out on top.²

The diet works in three phases. First, you eliminate all high-FODMAP foods for two to six weeks. Then you systematically reintroduce them one category at a time to identify your personal triggers. In a blinded reintroduction trial, roughly 80% of IBS patients responded to the initial elimination phase, but when individual FODMAPs were reintroduced, about 85% of the FODMAP categories triggered some symptom recurrence, with an average of around two to three specific FODMAPs per person causing trouble.³ Among specific FODMAP types, galacto-oligosaccharides (found in beans and lentils) stood out in one randomized trial as a category particularly tied to increased bloating.⁴

The takeaway isn’t that you need to avoid all FODMAPs forever. The reintroduction phase is the whole point: most people find they tolerate several FODMAP categories just fine and only need to limit one or two. A dietitian experienced with the protocol can make the process much smoother, since the elimination phase is restrictive enough to cause nutritional gaps if you wing it long-term.

Fiber Choices Matter More Than Fiber Quantity

Fiber advice for bloating is surprisingly nuanced. The blanket recommendation to “eat more fiber” can backfire if you pick the wrong type. Short-chain, rapidly fermentable fibers like oligosaccharides tend to produce gas quickly and worsen bloating in sensitive individuals. Longer-chain, moderately fermentable soluble fibers like psyllium produce far less gas and generally avoid triggering those symptoms.⁵ In a randomized trial comparing psyllium to a mixed soluble/insoluble fiber blend, both improved constipation symptoms and reduced bloating scores, though the mixed fiber group reported better results for flatulence specifically.⁶ If you’re adding fiber to your diet, start low, increase gradually over a couple of weeks, and favor psyllium or similar gentle soluble fibers over concentrated inulin or fructo-oligosaccharide supplements.

Watch for Sugar Alcohols

Sugar alcohols like sorbitol, mannitol, and xylitol show up in sugar-free gum, mints, protein bars, and “no sugar added” desserts. They’re poorly absorbed in the small intestine and draw water into the gut by osmosis, which can cause bloating, gas, and loose stools, especially if you’re not used to them. Adaptation does happen over time as gut bacteria adjust, but sensitivity varies widely from person to person.⁷ If you regularly chew sugar-free gum or eat protein bars and notice afternoon bloating, the sugar alcohols are worth investigating before you start eliminating whole food groups.

Get Moving After Meals

Physical activity is one of the simplest and most underrated ways to manage bloating. Being upright and moving around helps gas move through your intestines and exit your body faster. In a controlled study where gas was infused directly into the intestines, retention in the upright position was dramatically lower than when lying down, and gas clearance was substantially faster.⁸ A separate study found that mild physical activity reduced intestinal gas retention compared with rest and reduced measurable abdominal distension as well.⁹

You don’t need an intense workout. A 10-to-15-minute walk after a meal, or gentle movements that engage the abdominal muscles, can help push gas along. Research on post-meal physical activity in people with functional bloating found that abdominal muscle contractions during movement stimulate gut motility, and the shift to an upright position changes how pressure is distributed in the abdomen, both of which facilitate gas transit.¹⁰ If your instinct after a big meal is to lie on the couch, know that you’re making it physically harder for trapped gas to leave.

Slow Down on the Air Swallowing

Some of the gas in your belly didn’t come from fermentation at all. You swallowed it. Eating quickly, talking while chewing, drinking through straws, chewing gum, and sipping carbonated drinks all introduce air into the stomach and small intestine. Repeated air swallowing, sometimes called aerophagia, can produce enough gas to cause belching, abdominal distension, and increased flatulence.¹¹ Slowing down at meals, putting your fork down between bites, and limiting carbonated beverages and gum are low-effort changes that can meaningfully reduce the air load in your gut. These habits tend to be most helpful for people whose bloating is worst in the upper abdomen and accompanied by frequent belching.

Over-the-Counter Options With Evidence Behind Them

Several supplements and OTC products have actual trial data supporting their use for bloating, though the strength of the evidence varies.

Peppermint oil: Enteric-coated peppermint oil capsules relax smooth muscle in the intestinal wall by blocking calcium channels, which can ease cramping and the tight, pressured feeling of bloating.¹² The enteric coating matters: without it, peppermint oil dissolves in the stomach and can cause heartburn.
Alpha-galactosidase (Beano): This enzyme breaks down galacto-oligosaccharides before gut bacteria can ferment them. At higher doses, it reduced both hydrogen gas production and flatulence severity after a meal rich in fermentable carbohydrates.¹³ A separate trial found that full-dose alpha-galactosidase also reduced bloating specifically triggered by galacto-oligosaccharide ingestion.¹⁴ It’s useful for bean-heavy or lentil-heavy meals but won’t help with bloating from lactose, fructose, or other FODMAP categories.
Simethicone (Gas-X): Simethicone works by physically breaking up gas bubbles in the gut so they can be absorbed or expelled more easily. It does this through a mechanical process: the liquid films around gas bubbles are thinned and ruptured by silicone droplets.¹⁵ It’s safe and available without a prescription, but the evidence for subjective symptom relief is modest. It tends to work best when your bloating is clearly gas-related rather than driven by sensitivity or muscle dysfunction.
Ginger and artichoke extract: A randomized trial of a ginger-artichoke combination supplement found reductions in bloating and fullness over four weeks. The ginger component appeared to improve gastric motility, while artichoke extract may accelerate intestinal transit through increased bile secretion.¹⁶ The evidence here is thinner than for peppermint oil, but it’s a reasonable option if you prefer something plant-based and are dealing with upper-abdominal fullness.

Probiotics and What the Evidence Actually Shows

Probiotic supplements are marketed aggressively for bloating, but the reality is that results depend heavily on the specific strain. Not all probiotics are interchangeable. In a randomized trial, Bacillus coagulans MTCC 5856 produced a large drop in gas-related symptoms (distension, flatulence, burping) over the study period compared to placebo.¹⁷ A different Bacillus coagulans strain showed similar symptom improvements in children with IBS.¹⁸

On the other hand, the multi-strain probiotic VSL#3 reduced flatulence scores in IBS patients but did not produce a significant difference in bloating relief compared to placebo.¹⁹ That’s a meaningful distinction: less gas in the gut didn’t automatically translate to less bloating. This pattern shows up across probiotic research. A strain that reduces one gas-related symptom might not help with the broader sensation of bloating, which involves nerve sensitivity and muscular reflexes in addition to gas volume. If you want to try a probiotic, look for trials on the specific strain rather than assuming the category as a whole will help.

When Bacteria Are Overgrowing in the Wrong Place

For some people, the problem is structural: bacteria that belong in the colon have colonized the small intestine, a condition called small intestinal bacterial overgrowth, or SIBO. When those bacteria encounter food in the small intestine before it’s fully absorbed, they ferment it prematurely and produce gas in a part of the gut that isn’t designed to handle it. SIBO has been identified in a substantial proportion of people diagnosed with IBS, and it’s linked to bloating, abdominal discomfort, and altered bowel habits.²⁰

SIBO is typically diagnosed with a breath test and treated with antibiotics. Rifaximin, which acts locally in the gut without being absorbed into the bloodstream, is the best-studied option. A meta-analysis found an overall eradication rate of about 71%, with symptom improvement in roughly two-thirds of patients whose overgrowth was successfully cleared.²¹ The adverse event rate was low.²² If your bloating is persistent, started after food poisoning or abdominal surgery, and comes with diarrhea or nutritional deficiencies, SIBO is worth discussing with a gastroenterologist.

Biofeedback for Visible Distension

If your main complaint is that your belly physically swells after eating, the issue might have less to do with gas volume and more to do with how your body redistributes space. As mentioned earlier, visible distension often involves the diaphragm contracting downward while the anterior abdominal wall relaxes. Biofeedback therapy trains you to reverse this pattern: you learn to engage your abdominal wall muscles and relax the diaphragm and rib cage muscles using real-time monitoring of your trunk movements.

In an early proof-of-concept study, biofeedback reduced the activity of the intercostal muscles and diaphragm while activating the internal oblique muscles, and patients’ girth decreased measurably.²³ A subsequent randomized controlled trial confirmed these results: patients who received biofeedback learned to correct the dyssynergia triggered by a meal, and their clinical distension scores dropped by about two-thirds.²⁴ Biofeedback is still a specialty treatment, and not many centers offer it for abdominal distension specifically. But for people who bloat visibly without producing much extra gas, it targets the actual cause rather than a downstream symptom.

Hormonal Bloating Around Your Period

Many women experience bloating in the days leading up to menstruation, and it’s one of the most commonly reported premenstrual symptoms. Interestingly, research has shown that premenstrual bloating often occurs without any actual change in weight or measured body dimensions. Instead, women’s perception of their body size increases during the premenstrual phase, and the gap between perceived and actual body size is significant.²⁵

That doesn’t mean the sensation isn’t real. Hormonal shifts, particularly fluctuations in progesterone and estrogen, can slow gut motility and increase visceral sensitivity, making a normal amount of intestinal gas feel much more uncomfortable. For premenstrual bloating, the strategies that address sensitivity rather than gas production tend to be more useful: peppermint oil for its antispasmodic effect, gentle exercise, and stress management. Reducing salt intake in the days before your period can also help with any fluid retention that compounds the sensation.

Stress and the Gut-Brain Axis

Stress doesn’t just make you feel like your stomach is in knots. It physically changes how your digestive system moves. Acute psychological stress tends to slow gastric emptying while speeding up colonic transit, a mismatch that can leave food sitting too long in the upper gut while the lower gut churns.²⁶ Stress also appears to increase visceral sensitivity, meaning the same amount of gas or distension registers as more painful or uncomfortable when you’re anxious.

For people whose bloating flares during stressful periods, addressing the stress can be as effective as changing the diet. Cognitive behavioral therapy, gut-directed hypnotherapy, and even basic stress-reduction practices like slow diaphragmatic breathing have all shown benefits for functional gut symptoms in clinical trials. This is also where the biofeedback research circles back: learning to consciously control the diaphragm and abdominal wall isn’t just a physical intervention. It trains the brain-gut connection to stop reflexively bracing and distending in response to perceived threat, whether that threat is a heavy meal or a heavy workload.

When to See a Doctor Instead of Self-Treating

Most bloating is benign and manageable with the strategies above. But certain patterns warrant a medical evaluation rather than another round of dietary tinkering. Bloating that appeared suddenly and persists for weeks when it wasn’t a problem before, bloating accompanied by unintentional weight loss, blood in your stool, persistent vomiting, or progressive difficulty eating all deserve attention. These can signal conditions ranging from celiac disease and ovarian pathology to gastroparesis or mechanical obstruction, none of which will respond to peppermint oil or a walk around the block. New-onset bloating in anyone over 50 who hasn’t had recent screening is particularly worth investigating. A gastroenterologist can use breath testing, imaging, and sometimes endoscopy to rule out structural problems and point you toward the right treatment rather than letting you cycle through generic advice that doesn’t fit your situation.
