Most bloating responds well to a combination of dietary changes, simple lifestyle adjustments, and targeted supplements. The trick is figuring out which type of bloating you’re dealing with, because the causes vary and so do the fixes. Bloating can come from excess gas production, sluggish digestion, fluid retention, or even swallowed air, and each one calls for a slightly different approach.
Why Bloating Happens in the First Place
Your gut bacteria ferment carbohydrates that your small intestine couldn’t fully absorb. That fermentation produces hydrogen and methane gas, which stretches the intestinal walls and creates that uncomfortable, full feeling. People who bloat frequently tend to produce more gas from bacterial fermentation than average, and some have slower intestinal transit, meaning food and gas sit in the gut longer than they should.
But gas isn’t always the culprit. Bloating can also develop without significant gas retention. Increased fluid in the bowel, backed-up stool slowing everything down, or simply a larger volume of partially digested food can all create the same sensation. High-sodium meals promote water retention in the gut and throughout the body, which adds another layer. Understanding which of these drivers is behind your bloating helps you pick the right strategy.
Cut Back on Fermentable Carbs
The single most studied dietary approach for bloating is a low-FODMAP diet. FODMAPs are short-chain carbohydrates that your small intestine absorbs poorly. They pull extra water into the bowel and get rapidly fermented by gut bacteria, producing gas and distension. Common high-FODMAP foods include onions, garlic, wheat, beans, lentils, apples, pears, milk, yogurt, and artificial sweeteners like sorbitol.
Clinical trials consistently show that reducing these foods makes a real difference. In one trial, 81% of people on a low-FODMAP diet responded to treatment compared to 46% on a normal diet. Another found that 60% of people given structured low-FODMAP guidance met responder criteria, versus 28% who received standard dietary advice. Studies specifically measuring bloating severity found significantly lower scores in people following the low-FODMAP approach compared to controls.
The diet works in three phases: a strict elimination period (usually two to six weeks), followed by systematic reintroduction of one FODMAP group at a time, then a personalized long-term plan based on your individual triggers. Most people don’t need to avoid all FODMAPs forever. The reintroduction phase reveals which specific foods cause problems for you, so you only restrict what actually matters.
Watch Your Sodium Intake
Salt is an overlooked bloating trigger. A trial comparing three levels of sodium intake found that people eating the highest amount were 27% more likely to experience bloating than those eating the lowest amount. On the high-sodium diet, about 35% of participants on a standard Western diet reported bloating, compared to roughly 26% on the low-sodium version. High sodium promotes water retention and can suppress digestive efficiency, both of which contribute to that puffy, distended feeling.
Processed foods, restaurant meals, canned soups, deli meats, and salty snacks are the biggest sources. Cooking at home and reading labels for sodium content gives you the most control. For reference, the threshold where bloating risk climbed significantly in the trial was the equivalent of about 3,450 mg of sodium per day, which is close to what many people consume without realizing it.
Slow Down When You Eat
Swallowing air during meals, a condition called aerophagia, is a surprisingly common cause of bloating, gas, and gas pain. Eating too fast is one of the primary culprits. When you rush through a meal, you gulp air with every bite, and that air accumulates in your stomach and intestines.
The fix is straightforward: chew each bite thoroughly and swallow completely before taking the next one. Drinking through straws, chewing gum, and talking while eating also increase air intake. Carbonated drinks add gas directly. None of these changes cost anything or require supplements. For people whose bloating is worst right after meals and improves throughout the day, air swallowing is worth investigating first.
Move Your Body
Physical activity helps clear gas from the intestines. Even mild exercise, like a 15 to 20 minute walk after eating, enhances intestinal gas clearance and reduces bloating symptoms. The 2025 Seoul Consensus guidelines for irritable bowel syndrome specifically recommend mild exercise as a treatment for abdominal bloating. You don’t need intense workouts. Gentle movement stimulates the muscles of the gut wall, helping contents move along rather than sitting and fermenting.
Peppermint Oil for Crampy Bloating
Enteric-coated peppermint oil capsules are one of the better-supported natural options for bloating, especially when it comes with cramping or spasms. The active ingredient, L-menthol, blocks calcium channels in the smooth muscle of the intestinal wall. This relaxes the gut, reduces spasms, and lets trapped gas pass more easily. A meta-analysis of pooled clinical data from randomized controlled trials found that peppermint oil significantly improved symptoms in people with irritable bowel syndrome.
The enteric coating matters. Without it, the capsule dissolves in the stomach instead of the intestines, which can cause heartburn and reduce effectiveness. Look for products labeled “enteric-coated” and take them 30 to 60 minutes before meals.
Ginger Speeds Up Digestion
If your bloating feels like food is sitting in your stomach too long, ginger can help. A clinical trial found that 1.2 grams of ginger root powder sped up gastric emptying significantly. The median time for the stomach to empty half its contents dropped from about 16 minutes with placebo to about 12 minutes with ginger. Faster emptying means less time for food to ferment and produce gas in the upper gut.
You can take ginger as capsules (1,200 mg of dried ginger root is the dose used in the research), brew fresh ginger tea by steeping sliced ginger in hot water, or add fresh ginger to meals. Ginger is particularly useful for the heavy, “food won’t move” type of bloating that peaks after large meals.
Over-the-Counter Gas Relievers
Two common OTC products target gas, but they work differently and suit different situations. Alpha-galactosidase (sold as Beano) is an enzyme that breaks down the specific carbohydrates in beans, lentils, and certain vegetables before your gut bacteria can ferment them. You take it with the first bite of a trigger food, and it prevents gas from forming in the first place. It works best when your bloating is clearly tied to meals containing legumes or cruciferous vegetables.
Simethicone (sold as Gas-X) works after gas has already formed. It reduces the surface tension of gas bubbles in the gut, helping them merge and pass more easily. However, the clinical evidence for simethicone is weaker than many people assume. It can provide some comfort, but it doesn’t address the underlying cause of excess gas production.
Probiotics: Limited but Promising
The evidence for probiotics and bloating is more mixed than marketing suggests. A strain-specific meta-analysis found that Bacillus coagulans (specifically the strain Unique IS2) reduced bloating severity along with pain, flatulence, and other digestive symptoms. However, several other widely sold strains, including Lactobacillus plantarum 299v, Saccharomyces boulardii, Lactobacillus gasseri, and Lactobacillus casei Shirota, did not show significant effects on bloating in pooled data.
Even Bifidobacterium infantis 35624, often highlighted in IBS research, had insufficient evidence for bloating specifically, despite helping with other symptoms. The takeaway: probiotics aren’t a universal bloating fix. If you want to try one, look for strains with evidence for your specific symptom rather than grabbing a general “gut health” product. Give it at least four weeks before judging whether it’s working.
When Bloating Signals Something Bigger
Most bloating is functional, meaning uncomfortable but not dangerous. But certain patterns warrant medical attention. Bloating that gets progressively worse over weeks, persists for more than a week without relief, or is persistently painful rather than just uncomfortable needs evaluation. Bloating paired with fever, vomiting, blood in your stool, unintentional weight loss, or anemia can signal conditions that need diagnosis beyond dietary tweaks. Nighttime diarrhea and iron deficiency anemia are particularly important red flags that gastroenterologists use to decide whether further testing, like a colonoscopy, is needed.
