Gas and bloating usually respond well to a combination of simple physical techniques, dietary adjustments, and over-the-counter options. Most episodes aren’t a sign of anything serious, and you can often get relief within minutes to hours depending on the approach. Here’s what actually works, starting with the fastest options.
Quick Physical Relief
When you’re bloated right now, movement is your best first step. A short walk helps relax the muscles around your abdomen, hips, and lower back, which assists digestive transit and helps gas pass through. Even five to ten minutes can make a noticeable difference.
Certain body positions create gentle pressure on the abdomen that encourages gas to move. Lying on your back and pulling both knees to your chest stretches the lower back and hips while compressing the belly. Child’s pose (kneeling with your forehead to the floor and arms extended) does something similar. A seated forward bend, where you reach toward your toes with legs straight, stretches the back while pressing lightly on the abdomen. Squats and lying twists (knees falling to one side while your shoulders stay flat) also help. Hold each position for 30 seconds to a minute and repeat as needed.
The I-L-U Abdominal Massage
Your large intestine is shaped like an upside-down U. The right side goes up, the top crosses left, and the left side goes down. An abdominal massage that follows this path pushes gas and stool in the direction your body is already designed to move them. The technique has three steps, each named for the letter shape your hand traces.
- I stroke (down the left side): Start just under your left rib cage and slide your hand straight down toward your left hip bone. Repeat 10 times with gentle, steady pressure.
- L stroke (across and down): Start just below your right rib cage, move across the upper stomach to your left rib cage, then down to your left hip. Repeat 10 times.
- U stroke (up, across, and down): Start at your right hip, move up to your right rib cage, across to your left rib cage, then down to your left hip. Repeat 10 times.
Do all three steps in order. The idea is to clear the exit path first (the left, descending side), then progressively work gas from further back in the colon toward it.
Over-the-Counter Options
Simethicone (sold as Gas-X, Phazyme, and store brands) works by combining small gas bubbles in your gut into larger ones that are easier to pass. The usual adult dose is 40 to 125 mg taken four times a day, after meals and at bedtime, with a maximum of 500 mg in 24 hours. It’s available as capsules, chewable tablets, and liquid. Simethicone doesn’t get absorbed into the bloodstream, so side effects are rare.
Enteric-coated peppermint oil capsules are another option, particularly if your bloating comes with cramping. The coating prevents the oil from dissolving in your stomach (which can cause heartburn) and lets it reach your intestines, where it relaxes smooth muscle. The NHS recommends one capsule three times a day, taken 30 to 60 minutes before eating. You can increase to two capsules three times a day if one isn’t enough. If you’re buying it without a prescription, limit use to two weeks before checking in with a doctor.
Reduce Swallowed Air
A surprising amount of gas in your digestive tract isn’t produced there. It’s air you swallowed. This is called aerophagia, and it’s one of the most common and most fixable causes of bloating. The biggest contributors: eating too fast, talking while eating, chewing gum, sucking on hard candy, drinking through straws, and carbonated beverages. Smoking also increases air swallowing significantly.
The simplest fix is to slow down at meals. Chew each bite thoroughly and make sure you’ve swallowed before taking the next one. If you’re a gum chewer or hard candy person and you deal with frequent bloating, try cutting those habits for a week and see if it makes a difference. Swap carbonated drinks for still water. These changes sound minor, but for people whose bloating is driven primarily by swallowed air, they can resolve the problem almost entirely.
Dietary Triggers to Watch For
Certain carbohydrates are poorly absorbed in the small intestine and get fermented by bacteria in the colon, producing gas. These are collectively called FODMAPs, a group that includes fructose (in many fruits and honey), lactose (in dairy), fructans (in wheat, onions, and garlic), and sugar alcohols like sorbitol (in “sugar-free” products). Beans, lentils, broccoli, cabbage, and Brussels sprouts are also well-known gas producers.
If bloating is a regular problem, a low-FODMAP elimination diet is one of the most evidence-backed approaches. Research from Johns Hopkins has found it reduces symptoms in up to 86% of people with irritable bowel syndrome. The diet works in phases: you remove all high-FODMAP foods for two to six weeks, then reintroduce them one category at a time to identify your specific triggers. Most people don’t react to every FODMAP group, so the goal isn’t permanent restriction. It’s finding which foods cause your symptoms so you can avoid just those.
Even without a full elimination diet, keeping a simple food diary for a couple of weeks can reveal patterns. Write down what you eat and when bloating hits. Common culprits tend to become obvious fairly quickly.
What About Probiotics?
Probiotics are heavily marketed for bloating, but the evidence is more mixed than the packaging suggests. One clinical trial tested a well-studied strain (Bifidobacterium infantis 35624) in people with a history of bloating and abdominal discomfort who didn’t have a formal IBS diagnosis. After four weeks, the probiotic group had significantly more bloating-free days than the placebo group. However, overall severity scores for bloating and discomfort didn’t differ meaningfully between the two groups by the end of the study.
In people with diagnosed IBS, certain probiotic strains have shown stronger results, but “probiotic” is a broad category. Different strains do different things, and a generic probiotic supplement may not contain the strains with the best evidence for gas and bloating. If you want to try one, look for products that list specific strains (not just species) and give them at least four weeks before deciding whether they help.
Signs That Need Medical Attention
Most gas and bloating is uncomfortable but harmless. However, certain patterns suggest something more is going on. Watch for bloating that gets progressively worse over days or weeks, persists for more than a week without improvement, or is consistently painful rather than just uncomfortable. Bloating paired with fever, vomiting, blood in your stool, unintentional weight loss, or signs of anemia (like unusual fatigue or pallor) warrants a visit to your doctor. These can signal conditions ranging from food intolerances to inflammatory bowel disease or, rarely, something more serious that needs prompt evaluation.
