Passing gas between 14 and 23 times a day is completely normal. If you’re above that range, or your gas comes with bloating, cramping, or embarrassing timing, the problem is almost always manageable with changes to how you eat, what you eat, and a few targeted remedies.
Gas forms in two ways: you swallow air, or bacteria in your colon ferment carbohydrates your small intestine didn’t fully absorb. More than 99% of intestinal gas is hydrogen, carbon dioxide, and methane. The less than 1% that’s left is what actually smells. Understanding which source is driving your problem helps you pick the right fix.
Cut Down on Swallowed Air
A surprising amount of gas never comes from food at all. Every time you swallow, a small amount of air goes down with it. Certain habits dramatically increase that volume:
- Eating too fast or talking while you eat
- Chewing gum or sucking on hard candy
- Drinking through straws
- Carbonated drinks (soda, sparkling water, beer)
- Smoking
The fix is straightforward. Chew each bite slowly and swallow before taking the next one. Sip from a glass instead of a straw. Save conversations for after the meal rather than during it. These small adjustments can cut upper-GI gas (the kind that causes belching and upper belly bloating) significantly within a few days.
Identify Your Food Triggers
The biggest source of lower intestinal gas is fermentation. When certain carbohydrates reach your colon undigested, bacteria break them down and produce hydrogen, methane, and carbon dioxide as byproducts. The foods most likely to cause this are called FODMAPs, a group of short-chain carbohydrates your small intestine absorbs poorly. Common high-FODMAP foods include:
- Dairy: milk, yogurt, ice cream (especially if you’re lactose intolerant)
- Wheat-based products: bread, cereal, crackers
- Beans and lentils
- Certain vegetables: onions, garlic, artichokes, asparagus
- Certain fruits: apples, pears, cherries, peaches
You don’t need to avoid all of these permanently. A food diary is the simplest tool: write down what you eat and when gas or bloating hits. After two to three weeks, patterns usually become obvious. Some people find that beans are their main trigger while dairy causes no trouble at all. Others discover that onions and garlic are the culprits. Once you identify your personal triggers, you can reduce or adjust those specific foods rather than overhauling your entire diet.
The Lactose Question
Lactose intolerance is one of the most common enzyme deficiencies behind excessive gas. If dairy seems to be the issue, a hydrogen breath test can confirm it. During the test, you drink a lactose solution and breathe into a collection device over a few hours. If hydrogen in your breath rises by more than 20 parts per million, that’s a positive result. But many people simply try eliminating dairy for a week or two and see if symptoms improve, which is just as informative for practical purposes.
Over-the-Counter Options That Work
Two types of products target gas through different mechanisms. Simethicone (sold as Gas-X, Mylicon, and generics) works by breaking up gas bubbles in your digestive tract so they’re easier to pass. It doesn’t reduce gas production, but it can relieve the pressure and bloating you feel after a meal. The typical dose is 40 to 125 mg taken after meals and at bedtime, up to four times a day.
The other option is an enzyme supplement containing alpha-galactosidase (sold as Beano). This one actually prevents gas from forming by helping your body break down the complex carbohydrates in beans, broccoli, and other vegetables before they reach the colon. You take it with your first bite of the problem food, not after symptoms start. If dairy is the issue, a lactase enzyme supplement does the same job for lactose.
Peppermint Oil and Ginger
Enteric-coated peppermint oil capsules have strong clinical evidence behind them. A meta-analysis pooling data from seven trials found that peppermint oil was roughly 2.4 times more likely than placebo to improve overall digestive symptoms, including bloating and gas pain. For abdominal pain specifically, it was about 1.8 times more effective. The number needed to treat was just three, meaning for every three people who took it, one got meaningful relief they wouldn’t have gotten from placebo. That’s a solid effect for a natural remedy. Look for enteric-coated capsules specifically, because the coating prevents the oil from releasing in your stomach (where it can cause heartburn) and delivers it to the intestine instead.
Ginger has a longer traditional history but thinner clinical evidence. Small studies suggest it helps with gastric emptying and overall gut motility, which can reduce the time food sits around fermenting. Ginger tea or fresh ginger added to meals is a low-risk option worth trying, though the effect is likely more modest than peppermint oil.
Probiotics for Gas and Bloating
Probiotics aim to shift the balance of bacteria in your gut toward species that produce less gas. A meta-analysis of 23 trials involving over 2,500 people with irritable bowel syndrome found that probiotics significantly improved bloating and flatulence compared to placebo. The effect was real but moderate, with a number needed to treat of seven.
The challenge is that dozens of strains have been studied and no single “best” strain has emerged. Lactobacillus plantarum, Lactobacillus rhamnosus, and several Bifidobacterium species (including B. longum and B. lactis) all show up in positive trials. Multi-strain products tend to perform better in studies than single-strain ones. Give any probiotic at least three to four weeks before judging whether it’s helping, since it takes time for gut bacteria populations to shift.
Physical Techniques for Quick Relief
When gas is trapped and causing pain right now, movement helps. Even a short walk can stimulate the muscles around your intestines and help gas move through. Specific positions that apply gentle pressure to the abdomen or relax the hips tend to work fastest:
- Knee-to-chest: Lie on your back, pull both knees toward your chest, and tuck your chin. This compresses the abdomen and encourages gas to pass.
- Child’s pose: Kneel, then sit back onto your heels while stretching your arms forward on the floor. Your torso resting on your thighs creates gentle abdominal pressure.
- Lying twist: Lie flat, bend your knees with feet on the floor, then slowly lower both knees to one side while keeping your shoulders flat. This stretches the lower back and rotates the abdomen.
- Deep squat: Stand with feet shoulder-width apart and lower into a squat, keeping your weight in your heels. This position naturally relaxes the pelvic floor.
Abdominal self-massage can also help. Using moderate pressure, massage from the right side of your lower belly up, across, and down the left side, following the path of the colon. This can physically encourage gas to move toward the exit.
Signs That Gas May Signal Something Else
Occasional gas, even a lot of it, is rarely a medical problem. But gas paired with certain other symptoms can point to conditions like celiac disease, inflammatory bowel disease, or small intestinal bacterial overgrowth. Pay attention if you also have bloody stools, unexplained weight loss, persistent diarrhea or constipation, a change in how your stools look, or ongoing nausea and vomiting. Prolonged abdominal pain or chest pain alongside gas warrants immediate medical attention, since chest pain especially can mimic or mask cardiac issues.
