Most gas relief comes down to helping your body move gas through and out of your digestive tract more efficiently. Healthy adults pass gas about 10 times a day on average, with anything up to 20 times still considered normal. If you’re dealing with uncomfortable bloating, sharp pains, or more gas than usual, there are several effective strategies that work on different timescales, from immediate physical relief to longer-term dietary changes.
Why Gas Builds Up
Gas in your digestive tract comes from two main sources: swallowed air and bacterial fermentation. Every time you eat, drink, or swallow saliva, small amounts of air enter your stomach. Most of this exits as burps. The rest travels into your intestines.
The bigger contributor to uncomfortable gas is what happens in your colon. Bacteria living there ferment unabsorbed food residues, particularly certain carbohydrates your small intestine couldn’t fully break down. This fermentation produces hydrogen and methane, which either get absorbed into your blood and exhaled through your lungs or exit as flatulence. Some people’s gut bacteria simply produce more gas from the same amount of food, which explains why two people can eat the same meal and have very different experiences.
Get Moving for Quick Relief
One of the simplest and most effective things you can do is walk. Research comparing gas transit during mild physical activity versus rest found that exercise significantly reduced gas retention in the intestines and decreased abdominal distension by more than half. When participants sat still, gas accumulated and their abdomens measurably expanded. When they moved, gas passed through more efficiently.
You don’t need an intense workout. A 10 to 15 minute walk after a meal is enough to get things moving. Gentle, regular exercise throughout the day helps prevent gas from pooling in your intestines in the first place.
Positions That Help You Pass Gas
Certain body positions use gravity and gentle abdominal compression to help trapped gas move through your digestive tract. These are especially useful when you’re bloated at home and need relief now:
- Knee-to-chest pose: Lie on your back, bend your knees, and pull your thighs toward your chest while tucking your chin down. This compresses the abdomen and is sometimes called the “wind-relieving pose” for good reason.
- Child’s pose: Kneel on the floor, then sit back onto your heels while stretching your arms forward and letting your forehead rest on the ground. Your torso pressing against your thighs creates gentle pressure on the abdomen.
- Lying twist: Lie flat on your back with arms out to the sides. Bend your knees with feet together on the floor, then slowly lower both knees to one side until you feel a gentle stretch across your lower back. Repeat on the other side.
- Deep squat: Stand with feet shoulder-width apart and lower yourself as if sitting in a chair, hinging at the hips. This position naturally relaxes the pelvic floor and can help release trapped gas.
Massaging your abdomen from right to left (following the path of your colon) can also help push gas along.
Foods That Cause the Most Gas
Certain foods are notorious for producing gas because they contain carbohydrates that your small intestine can’t absorb, leaving them for colon bacteria to ferment. The most common culprits include:
- Beans and lentils
- Dairy products like milk, yogurt, and ice cream (especially if you’re lactose intolerant)
- Wheat-based foods such as bread, cereal, and crackers
- Certain vegetables, particularly onions, garlic, artichokes, and asparagus
- Certain fruits, including apples, pears, cherries, and peaches
These foods fall into a category called high-FODMAP foods, which are short-chain carbohydrates that ferment rapidly in the colon. You don’t necessarily need to eliminate all of them. A more practical approach is to track which specific foods trigger your symptoms and reduce those. Many people find that one or two categories are their main problem, not the entire list.
Adding a nonabsorbable sugar to the diet (even 10 grams) can nearly double daily gas frequency, from about 10 episodes to 19. This illustrates how sensitive gas production is to the type of carbohydrates reaching your colon.
Over-the-Counter Options
Two types of products address gas through completely different mechanisms, so choosing the right one depends on your situation.
Simethicone (Gas-X, Mylicon)
Simethicone works by reducing the surface tension of gas bubbles already in your digestive tract, causing small bubbles to merge into larger ones that are easier to pass through burping or flatulence. It doesn’t prevent gas from forming. It just helps your body expel what’s already there. Simethicone isn’t absorbed into your bloodstream, so side effects are minimal. Adults typically take 40 to 125 mg up to four times daily after meals, with a maximum of 500 mg per day.
Alpha-Galactosidase (Beano)
If beans, lentils, or cruciferous vegetables are your triggers, this enzyme supplement works preventively. It breaks down the specific complex sugars in these foods before they reach your colon, so bacteria have less material to ferment. The key is timing: you need to take it at the start of a meal, not after symptoms appear. It won’t help with gas from dairy (you’d need a lactase supplement for that) or gas that’s already formed.
Peppermint Oil for Bloating
Enteric-coated peppermint oil capsules have solid evidence behind them for reducing bloating and gas, particularly in people with irritable bowel syndrome. The enteric coating is important because it prevents the oil from releasing in your stomach, where it could cause heartburn, and instead delivers it to the intestines where it relaxes smooth muscle and helps gas pass through. Most studies used doses around 180 to 225 mg taken two to three times daily. Look for enteric-coated or delayed-release capsules specifically, not peppermint tea or plain oil drops.
Probiotics That Target Gas
Not all probiotics help with gas, but certain strains have clinical evidence for reducing bloating. A large systematic review comparing multiple strains found that Lactobacillus plantarum 299v, Bifidobacterium bifidum MIMBb75, and the multi-strain product VSL#3 were all significantly better than placebo at reducing bloating scores. Probiotics work by shifting the composition of your gut bacteria toward populations that produce less gas during fermentation, but this takes time. Expect to use them consistently for at least two to four weeks before judging whether they’re helping.
Eating Habits That Reduce Swallowed Air
A surprising amount of gas comes not from food itself but from how you eat. Eating quickly, talking while chewing, drinking through straws, chewing gum, and sipping carbonated drinks all increase the amount of air entering your stomach. Slowing down at meals and chewing with your mouth closed are free, immediate changes that can reduce upper-GI gas, which tends to cause burping and upper abdominal discomfort rather than lower intestinal bloating.
Signs That Gas May Need Medical Attention
Ordinary gas, even when uncomfortable, is rarely a sign of something serious. But gas paired with certain other symptoms can point to conditions like small intestinal bacterial overgrowth, where excess bacteria in the small intestine produce abnormal amounts of gas along with diarrhea and weight loss. See a doctor if your gas is accompanied by blood in your stool, unintentional weight loss, persistent diarrhea or constipation, ongoing nausea or vomiting, or a significant change in stool consistency. Prolonged abdominal pain or chest pain warrants immediate care.
