Most gas relief comes down to two things: helping trapped gas move through your digestive tract right now, and reducing how much gas your body produces in the first place. Healthy adults pass gas up to 25 times a day, so some is completely normal. But when it becomes painful, excessive, or embarrassing, there are straightforward ways to bring it under control.
What Causes Gas in the First Place
Gas enters your digestive system through two routes. The first is swallowed air. Every time you eat, drink, or swallow saliva, a small amount of air goes down with it. Certain habits dramatically increase that amount: eating too fast, talking while eating, chewing gum, sucking on hard candy, drinking through a straw, smoking, and drinking carbonated beverages. This swallowed air tends to cause burping and upper abdominal discomfort.
The second route is bacterial fermentation in your large intestine. When your gut bacteria break down undigested carbohydrates, they produce hydrogen, methane, and other gases as byproducts. This is the source of most flatulence and lower abdominal bloating. The more fermentable material that reaches your colon, the more gas you produce.
Quick Relief for Trapped Gas
When gas is already causing pain or pressure, gentle movement is one of the fastest ways to get things moving. A short walk helps stimulate the muscles of your digestive tract and encourages gas to pass naturally. Certain yoga-style positions work even better because they relax the hips, lower back, and abdominal muscles while creating gentle pressure that pushes gas through the bowels.
A few positions worth trying:
- Knee-to-chest pose: Lie on your back and pull one or both knees toward your chest. This stretches the lower back and compresses the abdomen, which helps release trapped gas.
- Child’s pose: Kneel on the floor and fold forward with your arms extended, resting your forehead on the ground. This relaxes the hips and lower back.
- Lying twist: Lie on your back with your knees bent, then drop both knees to one side while keeping your shoulders flat. The rotational stretch helps move gas along.
- Squats: A deep squat opens up the pelvic floor and can help you pass gas more easily.
For over-the-counter relief, simethicone (sold as Gas-X and similar brands) works by lowering the surface tension of gas bubbles in your stomach and intestines. This causes small, trapped bubbles to merge into larger ones that are easier for your body to expel through burping or flatulence. It doesn’t reduce gas production, but it breaks up the painful pockets of gas that cause that tight, bloated feeling. Simethicone is not absorbed into the bloodstream, so side effects are minimal.
Foods That Produce the Most Gas
Certain carbohydrates are poorly absorbed in the small intestine and end up being fermented by bacteria in the colon. Researchers group these under the acronym FODMAPs, and they show up in a surprisingly wide range of foods. The major categories:
- Legumes and pulses (beans, lentils, chickpeas) are among the most notorious gas producers, loaded with a type of carbohydrate called GOS that humans can’t fully digest.
- Certain vegetables like onions, garlic, asparagus, and artichokes are high in fructans, another fermentable carbohydrate. Cauliflower, mushrooms, and snow peas contain mannitol, a sugar alcohol with similar effects.
- Dairy foods cause gas in people who don’t produce enough lactase to break down lactose. This affects a large portion of the global population.
- Wheat, rye, and barley contain fructans, so bread, pasta, and cereal can contribute to gas even if you don’t have celiac disease.
- Certain fruits, especially apples, pears, mangoes, and watermelon, are high in excess fructose or sorbitol.
- Sugar-free products sweetened with sorbitol, xylitol, or erythritol are fermented rapidly in the colon.
You don’t need to avoid all of these permanently. The practical approach is to cut back broadly for two to three weeks, then reintroduce foods one category at a time to identify your personal triggers. Many people find that only one or two categories cause them real problems.
Enzyme Supplements That Help
If beans and other legumes are a major trigger for you, an enzyme supplement containing alpha-galactosidase (sold as Beano and similar products) can help. This enzyme breaks down the specific carbohydrates in beans that your body can’t digest on its own, reducing the amount of material available for bacteria to ferment. The key is timing: take it right before your first bite or within 30 minutes of starting your meal. It won’t help if you take it hours later, because the food has already moved past the point where the enzyme can act on it.
For lactose intolerance, lactase enzyme tablets work on the same principle. Take them with your first sip or bite of dairy, and they’ll break down the lactose before it reaches your colon.
Habits That Reduce Swallowed Air
If your gas tends to come with a lot of burping or upper abdominal pressure, swallowed air is likely a major contributor. The fixes are simple but require some awareness. Slow down while eating and put your fork down between bites. Stop chewing gum and sucking on hard candy, both of which cause near-constant swallowing. Drink from a glass instead of a straw. Cut back on carbonated drinks, which deliver dissolved gas directly into your stomach on top of the air you swallow while drinking them.
These changes can make a noticeable difference within a few days, especially if you were previously a fast eater or heavy gum chewer.
Peppermint Oil, Probiotics, and Other Remedies
Peppermint oil relaxes the smooth muscle of the digestive tract, which can ease cramping and discomfort associated with gas. In a randomized trial of 190 patients with irritable bowel syndrome, a small-intestinal-release peppermint oil capsule significantly reduced abdominal pain, discomfort, and overall symptom severity over eight weeks. Enteric-coated capsules are the form most likely to help, because they dissolve in the intestine rather than the stomach, where peppermint oil can worsen heartburn.
Probiotics get a lot of attention for digestive issues, but results are mixed and strain-specific. One strain with decent evidence behind it is Lactobacillus rhamnosus GG, which has shown reductions in bloating, gas, and abdominal discomfort. The challenge is that not every probiotic product contains strains studied for gas specifically, and benefits can take several weeks to appear. If you try a probiotic, give it at least three to four weeks before deciding whether it’s working.
Activated charcoal is widely sold for gas relief, but the evidence is poor. A study in the American Journal of Gastroenterology found that commonly used doses of activated charcoal failed to reduce the release of any gas produced by gut bacteria, including the sulfur-containing gases responsible for odor. The charcoal’s binding sites appear to become saturated during their passage through the digestive tract, leaving it ineffective by the time it reaches the colon where gas is actually produced.
Signs That Gas May Need Medical Attention
Ordinary gas, even when frequent or uncomfortable, is rarely a sign of something serious. But certain symptoms alongside gas warrant a visit to your doctor: blood in your stool, unintended weight loss, persistent changes in stool consistency (ongoing diarrhea or constipation), and recurring nausea or vomiting. Prolonged abdominal pain that doesn’t resolve, or any chest pain, should be evaluated promptly. These can point to conditions like inflammatory bowel disease, celiac disease, or other issues that need specific treatment beyond gas management.
