How to Reduce Bloating: 10 Evidence-Based Fixes

By Dr. Jane Smith · Published October 26, 2026 · 12 min read

If you want to know how to reduce bloating, start with the two jobs it involves: easing the pressure you feel now, and stopping it from building after your next meal. A 10–15 minute walk after eating, slower meals with less swallowed air, less salt and fiber added gradually all have trial or guideline support, and a short list of trigger foods explains much of the rest.

Bloating is common: in a survey of 88,795 Americans, 13.9% — nearly 1 in 7 — had felt it in the previous seven days. Below are 10 methods, split into quick home remedies for bloating and habits that prevent bloating after eating, followed by the warning signs that mean it's time to see a doctor. If your bloating comes with irritable bowel syndrome (IBS), our IBS-friendly meal plan lays out a full week of gentler meals.

What Causes Bloating After Eating?

Bloating after eating usually comes from one of four things: swallowed air, gas made when gut bacteria ferment carbohydrates you didn't fully digest, a large or fatty meal, or a gut that is more sensitive than average to normal amounts of gas.

• Swallowed air. Everyone swallows some air with food. Eating or drinking quickly, chewing gum, sucking hard candy, fizzy drinks, smoking and loose dentures all add more, according to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
• Fermentation. Sugars, starches and fiber that your small intestine doesn't fully absorb travel on to the large intestine, where bacteria break them down and release gas.
• Meal size and fat. NIDDK notes that high-fat foods can increase bloating, and doctors often suggest smaller, more frequent meals.
• A sensitive gut. In chronic bloating, the amount of gas often isn't the problem. A 2025 European consensus found no consistent link between how bloated people feel and how much gas their intestines hold, and named visceral hypersensitivity — a gut that registers normal stretching as discomfort — as one of the main drivers.

Bloating, the feeling of fullness or pressure, isn't the same as distension, a belly that visibly grows. NIDDK says only about half of people with bloating also have distension. Constipation, the menstrual cycle and conditions such as lactose intolerance, IBS and celiac disease can cause either.

Home Remedies for Bloating: 4 Quick Fixes

When you're bloated right now, the most useful home remedies for bloating help trapped gas move along or calm the muscles around it: gentle movement, a warm drink, an over-the-counter gas remedy and slower breathing.

1. Take a 10–15 Minute Walk After Meals

Walking is the simplest quick fix with trial support. In a 4-week randomized trial of 94 adults with functional bloating, 45 walked for 10–15 minutes after each meal and 49 took a prokinetic drug (domperidone) with activated dimethicone, an anti-gas agent. Both groups improved on belching, gas and abdominal discomfort, and walking did better than the medication on one measure: fullness and bloating after meals.

It is one modest trial, and the European consensus rates the evidence for exercise as very low. But a walk costs nothing and has no real downside. A slow loop around the block counts; you don't need to break a sweat.

2. Sip Peppermint or Ginger Tea, With Realistic Expectations

A warm cup of peppermint or ginger tea is a reasonable comfort measure, but the research behind both was done on capsules, not tea.

• Peppermint oil: a 2022 meta-analysis of 10 trials in 1,030 people with IBS found that peppermint oil capsules beat placebo for overall symptoms: for every four people treated, one more improved than would have on placebo. The authors rated the evidence very low quality, and side effects were more common with peppermint. Heartburn is the side effect most often reported, so skip peppermint if reflux is part of your problem.
• Ginger: in a small crossover study of 11 people with functional dyspepsia (chronic indigestion), 1.2 g of ginger in capsules made the stomach empty faster than placebo — a half-emptying time of 12.3 versus 16.1 minutes — but it didn't change their symptoms.

Neither tea has been tested directly for bloating. If a warm, non-fizzy drink helps you, there is little downside.

3. Try an Over-the-Counter Gas Remedy

Simethicone is the standard pharmacy option. MedlinePlus lists it for gas symptoms "such as uncomfortable or painful pressure, fullness, and bloating," and it usually causes no side effects when taken as directed. Keep expectations modest: the European consensus found insufficient evidence to recommend it for chronic, functional bloating.

If dairy is your trigger, NIDDK mentions lactase products as an option for people with lactose intolerance. Follow the label limits, and check with a pharmacist if you take other medicines.

4. Try Slow Diaphragmatic Breathing

If your belly visibly swells after meals, slow belly breathing may help. Normally the diaphragm relaxes and the abdominal wall tightens as your gut fills. In some people with distension the reflex runs backwards — the diaphragm pushes down while the belly wall slackens — a pattern called abdomino-phrenic dyssynergia. The 2023 American Gastroenterological Association (AGA) clinical practice update lists diaphragmatic breathing as a treatment for it.

Sit or lie comfortably with one hand on your belly. Breathe in slowly through your nose so your hand rises, then breathe out for longer than you breathed in. If visible distension is a regular problem, a gastroenterologist can confirm the pattern and may refer you for biofeedback.

How to Reduce Bloating After Eating: 6 Habits

Preventing bloating after eating comes down to what goes in with your food — air, salt, fat and fermentable carbohydrates — and how quickly you change your fiber intake.

5. Eat Slowly and Swallow Less Air

Slowing down is the simplest way to cut swallowed air. NIDDK's treatment advice for gas is practical:

• Eat more slowly, sit down to eat, and don't talk while chewing.
• Skip chewing gum and hard candy.
• Swap fizzy drinks for still ones, and drink without a straw.
• If you smoke, ask your doctor about quitting; if you wear dentures, make sure they fit.

6. Make Meals Smaller and Less Fatty

A very large or very fatty meal is a common reason for feeling bloated after eating. NIDDK says doctors may suggest smaller, more frequent meals and notes that high-fat foods can increase bloating. Try splitting a big dinner into a smaller dinner and a snack later, and keep fried foods and creamy sauces to modest portions.

Our portion sizes guide shows how to size a plate with your hand. To see how big and how fatty your usual meals really are, Caloria, the AI calorie tracker, breaks a plate down into calories, protein, carbs and fat from a single photo.

7. Go Easy on Salt

Salt makes bloating more likely, and the evidence comes from a controlled feeding trial. In the DASH-Sodium trial, 412 adults ate each of three sodium levels for 30 days, with all food provided. The high-sodium level raised the risk of bloating by 27% compared with the low one, whichever diet people were on.

At 2,100 kcal a day, the levels were 50, 100 and 150 mmol of sodium — roughly 1,150, 2,300 and 3,450 mg (our conversion, at 23 mg per mmol). The researchers noted that the high level matched average US intake, so most people have room to come down. Packaged soups, sauces, breads and deli meats are worth checking first. Our low sodium meal plan shows a full week of lower-salt meals.

8. Add Fiber Gradually, and Drink With It

Fiber helps prevent constipation, a common cause of bloating, but adding a lot at once can cause bloating itself, so build up slowly. In the same DASH-Sodium trial, the high-fiber diet (32 g a day, against 11 g on the control diet) raised the risk of bloating by 41%. A related OmniHeart feeding trial found that a high-fiber diet rich in protein carried a 40% higher risk of bloating than a high-fiber diet rich in carbohydrate.

That's not a reason to avoid fiber. NIDDK's constipation guidance puts adult needs at 22–34 g a day, depending on age and sex, and advises adding it a little at a time and drinking water and other fluids so the fiber works better. Soluble fiber such as psyllium is usually better tolerated than insoluble bran, according to MedlinePlus. Our high-fiber foods list ranks 40 foods by fiber per serving, so you can add one at a time.

9. Find Your Own Trigger Foods

A handful of food groups cause most diet-related bloating, but people react differently, so the list that matters is your own. These are the common culprits NIDDK and MedlinePlus name:

Lactose deserves a closer look. NIDDK estimates that about 36% of people in the US have lactose malabsorption, though not all of them get symptoms. If you suspect a food, NIDDK suggests keeping a diary of what you eat and drink alongside your symptoms; a food diary template makes that easy. Cut one suspect at a time for a week or two, then bring it back and see whether the bloating returns.

Beans, broccoli and whole grains are some of the most nutritious foods you can eat, so try a smaller portion before cutting them out. If several triggers overlap, and especially if you have IBS, a dietitian may suggest a low-FODMAP diet: a short elimination of fermentable carbohydrates followed by a staged reintroduction. The European consensus rates it effective for functional bloating, and the AGA advises doing it with a gastroenterology dietitian rather than alone.

10. Keep Constipation in Check

If you go days between bowel movements, treating constipation can be what fixes the bloating. In the US survey, chronic constipation was one of the conditions most strongly linked to bloating, and the AGA update advises doctors to consider constipation treatment for bloating whenever constipation is present.

The basics from method 8 apply: build fiber up gradually, drink enough fluid and stay active. If that isn't enough, talk to your doctor, who may suggest a laxative or check for a pelvic floor problem that makes it hard to empty your bowels.

What Doesn't Help as Much as You'd Think

Probiotics, gluten-free eating and long lists of banned foods are popular bloating fixes, but the evidence for each is thinner than the marketing suggests.

• Probiotics: expert guidelines disagree. The AGA update says probiotics should not be used to treat bloating, while the European consensus says selected strains may help, on low-quality evidence, and stresses that results from one product don't carry over to another. If you try one, use a single product and stop if nothing changes. Our guide to probiotics for gut health covers what the strains do.
• Going gluten-free: the European consensus found insufficient evidence for a gluten-free diet in bloating unless you have celiac disease — which a blood test can check, so ask before you cut gluten.
• Cutting food after food: a 2024 review notes that people often blame a food intolerance and adopt highly restrictive diets that fail to fix the distension while risking nutritional deficiencies. Test one food at a time instead.

When to See a Doctor About Bloating

See a doctor if bloating is new and won't go away, keeps getting worse or changes suddenly, or comes with any of these warning signs from NIDDK and MedlinePlus:

• Abdominal pain, vomiting or diarrhea
• Blood in your stool, or black, tarry stools
• Weight loss you can't explain
• Heartburn that is getting worse

For women, the CDC lists bloating, pelvic pain and feeling full too quickly among possible symptoms of ovarian cancer and advises seeing a doctor if any of them lasts two weeks or longer and isn't normal for you. Most bloating has a far more ordinary cause, but this pattern is worth having checked.

You probably won't need a scan. The AGA advises reserving imaging and endoscopy for people with warning signs, recent worsening or an abnormal examination. More often, a doctor will look for lactose or other carbohydrate intolerances, celiac disease (with a blood test), IBS, constipation or small intestinal bacterial overgrowth (SIBO), which a breath test can help identify.

Where to Start: Two Changes for This Week

For many people, bloating responds to small, unglamorous changes rather than supplements. Start with a 10–15 minute walk after your largest meal, and cut back on fizzy drinks, gum and sugar-free sweets. If you still bloat after a week or two, look at salt, meal size and how fast you've been adding fiber, then use a food diary to test one suspect food at a time.

If none of that helps, or any warning sign appears, a doctor can check for the conditions that diet alone won't fix. Pairing the diary with a photo of each meal in Caloria makes it easier to tell whether big or fatty meals are behind your pattern.
