The best approach to bloating depends on what’s causing it, but for most people, a combination of dietary changes and targeted over-the-counter products provides the most reliable relief. No single remedy works for everyone, so understanding your options helps you find what works for your body.
Dietary Changes That Make the Biggest Difference
For recurring bloating, what you eat matters more than any supplement or medication. A low-FODMAP diet, which temporarily removes certain fermentable carbohydrates, reduces symptoms in up to 86% of people with digestive issues like irritable bowel syndrome, according to Johns Hopkins Medicine. The foods most likely to trigger bloating include beans and lentils, wheat-based products, dairy, onions, garlic, and certain fruits like apples, cherries, pears, and peaches.
The low-FODMAP approach isn’t meant to be permanent. You follow a strict elimination phase for two to six weeks, then reintroduce foods one category at a time to pinpoint your personal triggers. Many people discover that only one or two food groups are responsible for most of their discomfort, which makes long-term management much simpler.
Beyond specific food triggers, eating habits play a role. Eating too quickly, drinking through straws, and chewing gum all introduce extra air into your digestive tract. Smaller, more frequent meals give your gut less to process at once, which can reduce the fermentation that produces gas.
Over-the-Counter Gas Relief
Simethicone (the active ingredient in Gas-X and similar products) is the most widely used OTC option for bloating. It works by breaking up gas bubbles in your digestive tract so they’re easier to pass. It won’t prevent gas from forming, but it can ease the pressure and discomfort you’re already feeling. The typical adult dose is 40 to 125 mg taken up to four times a day, usually after meals and at bedtime.
Simethicone doesn’t offer instant relief, but it tends to work within minutes to hours. It’s best suited for occasional bloating after a large meal rather than chronic, daily symptoms. If you find yourself reaching for it every day, that’s a sign you’d benefit more from identifying and addressing the root cause.
Enzyme Supplements for Specific Foods
If certain foods predictably make you bloated, digestive enzyme supplements can help your body break them down before they cause problems. Products containing alpha-galactosidase (like Beano) break down a type of non-absorbable fiber found in beans, root vegetables, and some dairy products. Normally, this fiber passes undigested into your intestines, where bacteria ferment it and produce gas. Taking the enzyme before eating breaks down the fiber before it ever reaches those bacteria.
For people with lactose intolerance, lactase supplements work on the same principle, breaking down milk sugar before it ferments in the gut. These enzyme products are preventive tools. You take them right before or with the meal, not after bloating has already started.
Peppermint Oil Capsules
Enteric-coated peppermint oil capsules relax the smooth muscle in your intestinal wall, which can ease the cramping and distension that come with bloating. A Dutch clinical trial of 190 patients with IBS found that small-intestinal-release peppermint oil produced significantly greater improvements in abdominal discomfort and overall symptom severity compared to placebo over eight weeks. The enteric coating is important: it prevents the oil from releasing in your stomach, where it can cause heartburn, and delivers it to the intestines where it’s needed.
Peppermint oil tends to be most helpful for people whose bloating comes with cramping or spasms, which is common in IBS. It’s less useful for bloating caused purely by excess gas production from food.
Probiotics for Ongoing Bloating
Probiotics can help with bloating, but the strain matters. Not all probiotic products target the same symptoms. One of the most studied strains for bloating is Bifidobacterium infantis 35624. A meta-analysis found that this strain significantly improved bloating and abdominal distension after four to eight weeks of daily use. Combination probiotics containing multiple strains also showed benefit.
The key with probiotics is patience. Unlike simethicone, which works the same day, probiotics need weeks to shift your gut bacterial balance enough to make a noticeable difference. If you’re going to try one, commit to at least a month before deciding whether it’s helping.
The Fiber Question
Fiber is tricky when it comes to bloating. It’s essential for healthy digestion, but the wrong type or too much too fast can make bloating worse. Research comparing psyllium (a soluble fiber) and wheat bran (an insoluble fiber) found that psyllium supplements actually increased bloating and flatulence, and adding wheat bran alongside it didn’t help. If you’re increasing your fiber intake to improve digestion, do it gradually over several weeks. A sudden jump from low to high fiber intake is one of the most common causes of temporary bloating.
Tracking Your Triggers
Harvard Health recommends keeping a food and symptom diary for a few weeks, noting what you ate, when you ate, and when bloating hit. Patterns often emerge quickly. You might discover that bloating always follows lunch (pointing to a specific food) or that it’s worse on stressful days (stress slows gut motility and increases gas retention). This kind of personal data is more useful than any general recommendation because bloating has so many possible causes.
Signs Your Bloating Needs Medical Attention
Most bloating is uncomfortable but harmless. However, Cleveland Clinic recommends seeing a healthcare provider if your bloating gets progressively worse, persists for more than a week, or is consistently painful. Bloating paired with fever, vomiting, bleeding, unintentional weight loss, or changes in bowel habits (new diarrhea or constipation) warrants prompt evaluation, as these can signal conditions beyond simple gas, including infections, food intolerances, or more serious digestive disorders.
