That tight, balloon-like pressure in your abdomen isn’t just annoying. It's distracting. You’re sitting in a meeting or out to dinner, and suddenly, you feel like your waistband is fighting back. We’ve all been there. Most people think they just need to pop an antacid and move on, but honestly, understanding how to get rid of gas in your stomach requires looking at your gut like a complex plumbing system rather than just a storage tank.
Gas is a natural byproduct of digestion. You swallow air when you eat, and your gut bacteria produce gases like hydrogen, carbon dioxide, and methane as they break down carbohydrates. Usually, this gas moves through the system and exits without much drama. But when it gets trapped—either due to slow motility, specific food triggers, or even the way you breathe—it causes that sharp, localized pain that makes you want to unbutton your pants immediately.
The immediate fixes that actually work
If you’re doubled over right now, you don't care about long-term dietary shifts. You need relief. Movement is king here. A quick walk around the block can stimulate the muscular contractions in your intestines (peristalsis) that push gas along. Even better? Yoga. Specifically, the "Wind-Relieving Pose" (Pawanmuktasana). You lie on your back and hug your knees to your chest. It’s simple. It works. It physically compresses the colon to help move things toward the exit.
Another trick involves heat. A heating pad or a warm bath relaxes the muscles of the gut wall. When those muscles relax, the gas can move more freely. It’s basically about reducing the "cramp" factor. Some people swear by peppermint tea, too. The menthol in peppermint has an antispasmodic effect on the smooth muscles of the digestive tract. Just be careful if you have GERD (acid reflux), because peppermint can relax the lower esophageal sphincter and make heartburn worse.
Why your "healthy" diet might be the culprit
It’s ironic. You start eating better—more kale, more beans, more lentils—and suddenly your stomach is a war zone. This happens because of high-FODMAP foods. FODMAPs are Fermented Oligosaccharides, Disaccharides, Monosaccharides, and Polyols. That’s a mouthful, but basically, they are short-chain carbs that the small intestine doesn’t absorb well. Instead, they sit in the large intestine and ferment.
- Cruciferous vegetables: Broccoli, cabbage, and cauliflower are famous for this. They contain raffinose, a complex sugar that humans lack the enzyme to digest fully.
- Legumes: Beans are the classic gas food for a reason. They’re packed with fiber and those same complex sugars.
- Sugar Alcohols: Sorbitol and xylitol in "sugar-free" gum or keto snacks are massive gas producers. Your gut bacteria go to town on them.
Dr. Monia Werlang, a gastroenterologist at the Mayo Clinic, often points out that it isn't just what you eat, but how your specific microbiome reacts to it. If you’ve recently upped your fiber intake, you likely did it too fast. Your gut needs weeks, not days, to adjust to a high-fiber lifestyle. If you go from zero to sixty with fiber, you're going to feel like a parade float.

The air you didn't know you were eating
Aerophagia is the medical term for swallowing air. You'd be surprised how much "gas" in the stomach is just trapped atmosphere. If you’re a fast eater, you’re gulping air with every bite. If you use a straw, you’re pulling air into your system before the liquid even hits your tongue.
Carbonated drinks are the most obvious offender. Those bubbles have to go somewhere. They either come back up as a burp or travel down through the intestines. Chewing gum and sucking on hard candies also keep your mouth open and your swallowing reflex active, leading to more trapped air. Honestly, if you're struggling with chronic bloating, ditching the sparkling water for a few days is the easiest experiment you can run.
How to get rid of gas in your stomach by fixing your habits
Sometimes the solution isn't a pill; it's a change in the physical mechanics of how you live. For example, did you know that your posture matters? Slouching compresses your digestive organs. When you sit upright or take a walk after a meal, you're giving your intestines the space they need to process food.
Over-the-counter help
There are three main players in the pharmacy aisle:
- Simethicone: This is the active ingredient in Gas-X. It doesn't "delete" gas. Instead, it acts as a surfactant. It breaks up large gas bubbles into smaller ones that are easier to pass. It’s generally very safe.
- Alpha-galactosidase: This is what’s in Beano. It’s an enzyme that helps you break down the complex sugars in beans and veggies. The catch? You have to take it with your first bite of food. Taking it after you're already bloated is like putting on a seatbelt after the car crash.
- Probiotics: These are a long game. Research published in Gastroenterology & Hepatology suggests that certain strains, like Bifidobacterium infantis, can help balance the gut flora and reduce gas production over time. But don't expect a miracle overnight.
When it's more than just a heavy dinner
Sometimes gas is a symptom of an underlying condition. If you’ve tried the teas and the walks and you’re still miserable, it might be time to look deeper.

Small Intestinal Bacterial Overgrowth (SIBO) is a condition where bacteria that normally live in the large intestine migrate to the small intestine. They start fermenting food way too early in the digestive process. This leads to extreme bloating, often right after eating.
Then there’s food intolerances. Lactose intolerance is the big one. As we age, many of us lose the lactase enzyme needed to break down milk sugars. Celiac disease or non-celiac gluten sensitivity can also cause massive gas. If your bloating is accompanied by unintentional weight loss, blood in the stool, or severe abdominal pain, that's your body telling you to see a doctor. It’s not just "something you ate" at that point.
The connection between stress and your gut
The gut-brain axis is real. Your gut is lined with neurons—so many it’s often called the "second brain." When you’re stressed, your body enters "fight or flight" mode. Digestion is a "rest and digest" function. Stress slows down the movement of food through your system. When food sits too long, it ferments. When it ferments, you get gas.
Ever notice how you get "butterflies" or an upset stomach before a big presentation? That’s the connection. Deep diaphragmatic breathing can actually help. It calms the nervous system and physically massages the internal organs. Just five minutes of slow, deep belly breathing can sometimes do more for gas than a handful of supplements.
Practical steps for long-term relief
Start a food diary. It sounds tedious, but it's the only way to find your specific triggers. You might find that it's not "veggies" in general, but specifically onions or garlic that set you off.

Try the "low-FODMAP" diet for two weeks. Don't do it forever—it's too restrictive—but use it as a reset. Slowly reintroduce foods one by one to see which ones cause the pressure to return.
Drink more water, but not during meals. Drinking too much liquid while eating can dilute digestive enzymes and lead to more air swallowing. Sip throughout the day instead.
Lastly, look at your supplements. Some protein powders, especially those with whey or artificial sweeteners, are notorious for causing "protein farts." Switching to a cleaner, fermented pea protein or a different brand might solve the problem instantly.
Moving forward
Fixing a gassy stomach is rarely about one single "cure." It’s a combination of physical movement, identifying your personal trigger foods, and managing how much air you’re physically swallowing.
- Audit your habits: Stop using straws and slow down your chewing. Aim for 20 chews per bite.
- Heat and movement: Use a heating pad and try the wind-relieving yoga pose when the pain hits.
- Enzymes: Keep an enzyme supplement like Beano on hand for high-fiber meals.
- Track your symptoms: If the gas is chronic, keep a log of what you ate and how you felt for 7 days to show a doctor.
- Check for SIBO: If bloating happens within 30 minutes of eating regardless of what you eat, ask your GP about a breath test.
