Several straightforward changes to how you eat, along with a few targeted supplements and over-the-counter options, can significantly reduce gas and bloating. Most people pass gas up to 25 times a day, so some is completely normal. The goal isn’t to eliminate gas entirely but to bring it down to a comfortable level and reduce that uncomfortable, distended feeling.
Adjust How You Eat, Not Just What
A surprising amount of gas comes from swallowed air rather than digestion. Eating quickly, talking while chewing, drinking through straws, and chewing gum all push extra air into your stomach. Slowing down at meals and chewing thoroughly gives your digestive system a head start on breaking food down and cuts the volume of air you swallow.
Carbonated drinks are another obvious but often overlooked source. Every sip delivers dissolved carbon dioxide directly into your gut. If bloating is a regular problem, cutting back on sparkling water, soda, and beer for a week or two is one of the simplest experiments you can run.
Foods That Cause the Most Gas
Gas from digestion happens when bacteria in your large intestine ferment carbohydrates your small intestine couldn’t fully absorb. Some foods are far more likely to cause this than others. Beans, lentils, broccoli, cabbage, Brussels sprouts, onions, and whole grains are common triggers because they contain complex fibers and sugars that human enzymes can’t break down on their own.
Dairy is another major source for people who don’t produce enough of the enzyme that digests milk sugar. If you notice bloating consistently after milk, ice cream, or soft cheese, lactose intolerance is worth investigating. Artificial sweeteners like sorbitol and mannitol, found in sugar-free gum and candy, also ferment readily in the gut and can cause significant bloating even in small amounts.
You don’t necessarily need to avoid all these foods permanently. Cooking vegetables thoroughly, soaking dried beans before cooking, and introducing high-fiber foods gradually all help your gut adapt and produce less gas over time.
The Low FODMAP Approach
FODMAPs are a group of short-chain carbohydrates found in a wide range of foods, from apples and wheat to garlic and honey. They’re poorly absorbed in the small intestine and rapidly fermented by gut bacteria, producing gas and drawing water into the bowel. Research from Johns Hopkins has found that a low FODMAP diet reduces digestive symptoms in up to 86% of people.
The diet works in three phases. First, you remove all high FODMAP foods for two to six weeks. Then you reintroduce them one category at a time, tracking which ones trigger symptoms. Finally, you settle into a personalized long-term diet that avoids only your specific triggers. It’s not meant to be permanent or overly restrictive. Working with a dietitian makes the process much smoother, since FODMAP content isn’t always intuitive (watermelon is high FODMAP, for instance, while strawberries are low).
Over-the-Counter Options That Work
Simethicone is the most widely available anti-gas medication and works by breaking large gas bubbles in your digestive tract into smaller ones that are easier to pass. The typical adult dose is 40 to 125 milligrams taken four times a day, after meals and at bedtime, with a maximum of 500 milligrams in 24 hours. It doesn’t prevent gas from forming, but it can relieve the pressure and discomfort of gas that’s already trapped.
Enzyme supplements take a different approach by helping you digest the foods that cause gas in the first place. Products containing alpha-galactosidase break down the non-absorbable fiber in beans, root vegetables, and some dairy products before it reaches your large intestine, where bacteria would otherwise ferment it. The key is timing: you take it right before eating or with your first bite, not after symptoms appear. For lactose intolerance specifically, lactase enzyme supplements work on the same principle, breaking down milk sugar before it can ferment.
Peppermint Oil for Bloating
Enteric-coated peppermint oil capsules have solid clinical evidence behind them, particularly for people with irritable bowel syndrome. The menthol in peppermint relaxes the smooth muscle lining your intestines, which helps trapped gas move through more easily and reduces the spasms that contribute to bloating pain. A randomized, double-blind trial published in Gastroenterology confirmed that peppermint oil significantly improved symptoms compared to placebo.
The enteric coating matters. Without it, the peppermint oil dissolves in your stomach, which can cause heartburn and won’t deliver the active ingredient to the intestines where it’s needed. Look specifically for enteric-coated capsules rather than peppermint tea, which, while soothing, delivers a much lower and less targeted dose.
Probiotics: Helpful but Strain-Specific
Not all probiotics help with bloating. The benefits are tied to specific strains, and most products on the shelf haven’t been tested for gas or bloating specifically. One strain with the strongest evidence is Bifidobacterium infantis 35624, which has been studied in multiple clinical trials for irritable bowel syndrome symptoms including bloating. At the right dose, it showed meaningful improvement in bloating scores compared to placebo.
Probiotics generally take two to four weeks of consistent daily use before you’ll notice a difference. If you don’t see improvement after a month, that particular strain likely isn’t addressing your issue. It’s worth trying a different well-studied strain rather than assuming probiotics as a category don’t work for you.
Physical Movement and Positioning
A short walk after eating is one of the most effective and underused tools for bloating. Gentle movement stimulates the muscles of your digestive tract, helping food and gas move through faster. Even 10 to 15 minutes of walking after a meal can make a noticeable difference, especially after larger meals.
When bloating hits and you’re at home, lying on your left side can help gas move through your colon more easily because of the way the large intestine curves. Gentle yoga poses that compress the abdomen, like pulling your knees to your chest while lying on your back, can also help release trapped gas. These aren’t long-term fixes, but they provide real relief in the moment.
When Bloating Signals Something Else
Occasional bloating after a big meal or a plate of beans is normal. Bloating that gets progressively worse, persists for more than a week, or comes with persistent pain deserves a closer look. Alarm symptoms to watch for include unintentional weight loss, fever, vomiting, blood in your stool, signs of anemia (like unusual fatigue or pale skin), and significant changes in bowel habits like new diarrhea or constipation. These patterns can point to conditions like celiac disease, small intestinal bacterial overgrowth, ovarian issues, or inflammatory bowel disease that require proper diagnosis and targeted treatment rather than dietary changes alone.
