Most gas and bloating responds well to a combination of simple dietary changes, physical movement, and over-the-counter options. The fastest relief comes from addressing the root cause, whether that’s swallowed air, certain foods, or sluggish digestion. Here’s what actually works.
Habits That Reduce Swallowed Air
A surprising amount of bloating comes from air you swallow without realizing it. This is called aerophagia, and the Cleveland Clinic lists it as a direct cause of bloating, gas, and gas pain. The biggest culprits are eating too fast, talking while eating, chewing gum, sucking on hard candy, using straws, drinking carbonated beverages, and smoking.
The fixes are straightforward: chew slowly, finish one bite before taking the next, sip from a glass instead of a straw, and save conversation for after the meal. Cutting out carbonated drinks and gum alone can make a noticeable difference within a day or two, since you’re eliminating a constant stream of air entering your digestive tract.
Dietary Changes With the Strongest Evidence
Certain carbohydrates ferment rapidly in the gut, producing gas as a byproduct. These are collectively called FODMAPs, short-chain carbohydrates found in foods like onions, garlic, wheat, beans, certain fruits, and dairy. A low-FODMAP diet, which temporarily removes these foods and then reintroduces them one at a time, reduces bloating and gas symptoms in up to 86% of people, according to Johns Hopkins Medicine.
The elimination phase typically lasts two to six weeks. After that, you reintroduce foods individually to identify your specific triggers. Most people don’t need to avoid all FODMAPs permanently. They just need to know which ones their gut handles poorly. Common triggers vary widely from person to person, so the reintroduction phase matters as much as the elimination.
Even without a full FODMAP protocol, you can start by reducing the most common gas-producing foods: beans, lentils, broccoli, cabbage, Brussels sprouts, and dairy (if you suspect lactose intolerance). Keeping a simple food diary for a week or two often reveals patterns you wouldn’t otherwise notice.
Over-the-Counter Options
Simethicone is the most widely available OTC remedy for gas. It works by merging small gas bubbles in your gut into larger ones, making trapped air easier to pass. It won’t prevent gas from forming, but it can relieve that uncomfortable, pressurized feeling relatively quickly. You’ll find it in products like Gas-X and Mylanta Gas. It’s considered very safe because it isn’t absorbed into the bloodstream.
Alpha-galactosidase (sold as Beano) takes a different approach. It supplies an enzyme that breaks down the complex carbohydrates in beans and vegetables before they reach the bacteria in your colon. You take it with or just before a meal containing those foods. It’s most useful if your bloating is tied to specific high-fiber meals.
Activated charcoal is sometimes marketed for gas, but the evidence is mixed. The Cleveland Clinic notes that while activated charcoal works well for poisoning treatment in hospitals, there are conflicting results for gas, bloating, and nausea relief. It can also interfere with medication absorption, so it’s not the best first choice.
Peppermint Oil for Cramping and Bloating
Enteric-coated peppermint oil capsules are one of the better-studied natural options. Peppermint oil relaxes the muscles of the bowel, which relieves the painful spasms and cramps that often accompany bloating. The enteric coating is important: it prevents the capsule from dissolving in your stomach so the oil reaches the intestines where it’s needed.
Peppermint oil is commonly used for irritable bowel syndrome, but it can help anyone whose bloating involves cramping or tightness. Peppermint tea offers a milder version of the same effect, though the concentration is much lower than a capsule. If you have acid reflux, peppermint can sometimes make that worse by relaxing the valve between the stomach and esophagus.
Probiotics: What the Research Shows
Probiotics get a lot of attention for bloating, but the evidence is strain-specific and more modest than marketing suggests. One of the most studied strains, Bifidobacterium infantis 35624, showed significantly more bloating-free days compared to placebo in a clinical trial. However, the overall severity scores for bloating at the end of four weeks didn’t differ meaningfully between the probiotic and placebo groups in people without a diagnosed condition like IBS.
In IBS patients, specific strains have shown stronger benefits. But if you’re generally healthy and just dealing with occasional bloating, probiotics are unlikely to be a dramatic fix. They’re worth trying for a few weeks, especially if your bloating followed a course of antibiotics or a stomach illness, but don’t expect overnight results. Look for products that name specific strains rather than just genus and species.
Physical Movements That Help Pass Gas
When gas is already trapped, certain body positions use gravity and gentle abdominal compression to move it through. These work best when you’re feeling acutely bloated and want relief within minutes.
- Knee-to-chest pose: Lie on your back, bend both knees, and pull your thighs toward your chest. Tuck your chin down. This compresses the abdomen and encourages gas to move.
- Child’s pose: Kneel on the floor, then sit back onto your heels while stretching your arms forward and resting your forehead on the ground. Your torso resting on your thighs creates gentle abdominal pressure.
- Lying twist: Lie flat with arms out to the sides. Bend your knees with feet on the floor, then lower both knees to one side. This stretches the lower back and helps rotate gas through the colon.
- Deep squat: Stand with feet shoulder-width apart and lower into a deep squat. This position naturally opens the pelvic floor and straightens the pathway for gas to exit.
Abdominal self-massage also helps. Using moderate pressure, massage from your right lower abdomen up toward your ribs, across the top of your belly, and down the left side. This follows the natural path of the colon and can physically push gas toward the exit. A brisk 10 to 15 minute walk works similarly by stimulating the muscles of the intestinal wall to contract and move things along.
Warning Signs Worth Paying Attention To
Occasional gas and bloating are normal. But certain symptoms alongside bloating point to something that needs medical evaluation: unintentional weight loss, blood in your stool, persistent vomiting, fever, difficulty swallowing, jaundice (yellowing of the skin or eyes), or bloating that keeps getting worse over weeks rather than coming and going. New-onset bloating in adults over 55 also warrants a closer look, as do symptoms that align with a family history of gastrointestinal or ovarian cancer. Bloating that doesn’t respond to any of the strategies above after several weeks is another reason to get checked out.
