Most gassy stomachs can be relieved within minutes to hours using a combination of movement, over-the-counter remedies, and simple changes to how you eat. Gas is one of the most common digestive complaints, and while it’s rarely dangerous, it can be genuinely uncomfortable. Here’s what actually works, starting with the fastest options.
Quick Physical Relief
Moving your body is often the fastest way to get trapped gas out. A short walk activates your intestinal muscles and helps gas move through your system naturally. If walking isn’t enough, specific yoga-style positions use gravity and gentle compression to push gas along.
The most effective pose is the wind-relieving pose (it’s literally named for this). Lie on your back, pull both knees into your chest, and hold them there for 30 seconds to a minute. This compresses your abdomen and encourages gas to release. Child’s pose works similarly: kneel on the floor, sit back on your heels, and fold forward with your arms stretched out in front of you. The pressure on your belly gently massages your intestines. A two-knee spinal twist, where you lie on your back and drop both bent knees to one side, stretches and compresses your digestive organs from a different angle. Cycling through these positions for five to ten minutes often produces noticeable relief.
Over-the-Counter Options That Work
Simethicone (the active ingredient in Gas-X and Mylanta Gas) works by breaking up large gas bubbles into smaller ones, making them easier to pass. The typical adult dose is 40 to 125 mg taken after meals and at bedtime, up to four times a day, with a maximum of 500 mg in 24 hours. It won’t prevent gas from forming, but it can reduce the pressure and bloating you feel once gas is already trapped.
If your gas tends to flare after eating beans, broccoli, cabbage, or other high-fiber vegetables, an enzyme supplement like Beano can help. It contains an enzyme that breaks down the complex sugars in these foods before bacteria in your gut can ferment them into gas. The key is taking it with your first bite, not after symptoms start.
Peppermint Oil for Intestinal Spasms
Peppermint oil relaxes the smooth muscle in your intestinal wall, which can ease cramping and help trapped gas move through. The clinically tested dose is 0.2 to 0.4 mL taken three times daily in enteric-coated capsules. The enteric coating matters: without it, peppermint oil dissolves in your stomach and relaxes the valve between your stomach and esophagus, which can cause heartburn. Enteric-coated capsules pass through your stomach intact and release in your lower gut, where you actually need the relief.
Foods That Cause the Most Gas
Your gut bacteria produce gas when they ferment certain carbohydrates that your small intestine can’t fully absorb. The worst offenders fall into a category called FODMAPs, which are short-chain sugars found in a surprisingly wide range of everyday foods:
- Dairy: milk, yogurt, and ice cream (especially if you’re lactose intolerant)
- Wheat-based foods: bread, cereal, crackers, and pasta
- Legumes: beans and lentils
- Certain vegetables: onions, garlic, asparagus, and artichokes
- Certain fruits: apples, pears, cherries, and peaches
You don’t necessarily need to eliminate all of these permanently. A structured low-FODMAP approach involves cutting these foods out strictly for two to six weeks until symptoms resolve, then reintroducing them one at a time to identify your personal triggers. Most people find they’re sensitive to only a few categories, not all of them. Monash University, which developed the protocol, emphasizes that the strict phase is temporary, not a lifelong diet.
Eating Habits That Make Gas Worse
A significant portion of stomach gas comes not from food fermentation but from swallowed air. You swallow small amounts of air constantly, but certain habits dramatically increase the volume. Eating too fast, talking while chewing, drinking through straws, chewing gum, sucking on hard candy, and drinking carbonated beverages all force extra air into your stomach. Smoking does the same thing.
The fixes are straightforward. Chew slowly and finish each bite before taking the next one. Sip from a glass instead of a straw. Save conversation for after your meal rather than during it. Cut back on carbonated drinks. If you chew gum throughout the day, try stopping for a week and see if your symptoms improve. These changes sound minor, but swallowed air is one of the most underestimated causes of a bloated, gassy feeling, especially in the upper stomach.
Probiotics for Ongoing Gas Problems
If gas is a recurring issue rather than an occasional one, probiotics may help rebalance the bacteria in your gut. A meta-analysis of 23 clinical trials involving over 2,500 people with irritable bowel syndrome found that probiotics significantly improved bloating and flatulence compared to placebo. The strains with the most evidence behind them belong to the Bifidobacterium family, particularly Bifidobacterium longum subspecies infantis (sold as Align) and related strains like Bifidobacterium animalis and Bifidobacterium bifidum.
Probiotics aren’t an instant fix. Most people need several weeks of daily use before noticing a difference. The quality of evidence is still considered low overall, so results vary from person to person. But for chronic gassiness that doesn’t respond well to dietary changes alone, they’re a reasonable option to try.
When Gas Could Signal Something Else
Occasional gas is normal. Persistent, worsening, or unusually severe gas can sometimes point to an underlying condition. The two most common are irritable bowel syndrome (IBS) and small intestinal bacterial overgrowth (SIBO). The symptoms overlap heavily, but there’s a useful rule of thumb: IBS tends to be more pain-dominant, while SIBO tends to be more bloating-dominant. SIBO occurs when bacteria that normally live in your large intestine colonize your small intestine, where they ferment food earlier in the digestive process and produce excess gas.
Celiac disease is another possibility. It can cause bloating, flatulence, diarrhea, or constipation, and over time may lead to anemia from poor nutrient absorption.
Certain warning signs suggest gas is part of a bigger problem that needs medical evaluation: unintentional weight loss, blood in your stool, fever, difficulty swallowing, jaundice, vomiting, nighttime diarrhea that wakes you up, or symptoms that keep getting progressively worse. New digestive symptoms appearing for the first time in older adults, or in anyone with a history of cancer or abdominal surgery, also warrant a closer look.
