Most bloating and gas comes down to two things: what you eat and how much air ends up in your digestive tract. The good news is that both are highly fixable with simple changes to your habits, diet, and a few targeted remedies. Here’s what actually works.
Cut Down on Swallowed Air
A surprising amount of gas in your stomach and intestines isn’t produced there at all. You swallow it. This is called aerophagia, and it’s one of the most common and most overlooked causes of bloating. The main culprits are everyday habits you probably don’t think twice about: chewing gum, drinking through straws, sucking on hard candy, eating too fast, talking while eating, drinking carbonated beverages, and smoking.
The fixes are straightforward. Chew your food slowly and swallow one bite before taking the next. Sip from a glass instead of using a straw. Save conversations for after meals rather than during them. Skip the gum and mints. These changes alone can make a noticeable difference within a day or two, especially if air swallowing was your primary trigger.
Identify Your Dietary Triggers
Certain foods cause far more gas than others because they contain short-chain carbohydrates that your small intestine can’t fully absorb. These pass into your large intestine, where bacteria ferment them and produce gas. A low-FODMAP diet, which temporarily removes these fermentable carbohydrates, reduces symptoms in up to 86% of people, according to Johns Hopkins Medicine.
The biggest offenders include:
- Dairy: milk, yogurt, and ice cream
- Wheat-based foods: bread, cereal, crackers
- Beans and lentils
- Certain vegetables: onions, garlic, asparagus, and artichokes
- Certain fruits: apples, pears, cherries, and peaches
You don’t necessarily need to avoid all of these forever. The standard approach is to eliminate high-FODMAP foods for two to six weeks, then reintroduce them one at a time to figure out which specific ones your gut reacts to. Many people find they only have trouble with one or two categories, not the entire list.
Take a Post-Meal Walk
Light movement after eating helps your gastrointestinal tract keep things moving, which prevents the gas buildup that leads to that uncomfortable, distended feeling. A short walk within an hour of finishing a meal is one of the simplest and most effective habits you can build. Some research suggests even five minutes of light activity is enough to make a difference, though 10 to 15 minutes is a reasonable target. You don’t need to break a sweat. A casual stroll around the block works.
Try an Abdominal Self-Massage
When gas is already trapped and you want physical relief, a technique called the “I Love You” massage can help move it through your colon. Women’s College Hospital recommends doing it once daily, using soap in the shower or lotion on your fingertips. Always massage from your right side to your left, following the natural direction of your digestive tract.
Start by stroking with moderate pressure from your left ribcage straight down to your left hipbone, forming the letter “I.” Do this 10 times. Next, form the letter “L” by stroking from your right ribcage across to the left, then down to the left hipbone. Repeat 10 times. Finally, trace a “U” shape: start at your right hipbone, go up to your right ribcage, across to the left ribcage, and down to your left hipbone. Do 10 strokes. Finish with one to two minutes of gentle clockwise circles around your belly button to stimulate the small intestine.
Over-the-Counter Options That Work
Simethicone (sold as Gas-X and similar brands) is the most widely available OTC remedy for gas. It works by breaking up gas bubbles in your stomach and intestines so they’re easier to pass. The typical 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 generally very well tolerated and acts quickly.
Enzyme-based products like Beano contain an enzyme that breaks down the complex sugars in beans, vegetables, and grains before they reach your large intestine and start fermenting. The key is timing: you take them with your first bite of a trigger food, not after symptoms have already started.
Peppermint Oil for Gut Muscle Relaxation
Enteric-coated peppermint oil capsules relax the smooth muscle lining your digestive tract, which can ease the cramping and pressure that comes with trapped gas. The coating is important because it lets the capsule pass through your stomach and dissolve in your intestines, where the oil is needed. The standard dose for adults is 0.2 to 0.4 mL of oil three times daily. Look for products specifically labeled as enteric-coated, since regular peppermint oil can cause heartburn by relaxing the valve at the top of your stomach.
Probiotics: Which Strains Actually Help
Not all probiotics are equal when it comes to bloating. A systematic review published in The Lancet found that specific single-strain probiotics showed measurable benefits for bloating, but multi-strain “kitchen sink” formulas weren’t consistently effective. The strain with the strongest evidence is Bifidobacterium infantis 35624 (sold under the brand name Alflorex or Align in some markets), which outperformed placebo across multiple trials for reducing bloating scores.
Bifidobacterium animalis DN-173010, commonly found in certain fermented dairy products, also showed positive results. If you’re going to try a probiotic, check the label for specific strain numbers rather than just the species name. Give it at least four weeks before deciding whether it’s helping, since gut bacteria populations shift gradually.
When Bloating Signals Something Bigger
Occasional bloating after a heavy meal is normal. Persistent or worsening bloating is worth paying attention to. The Cleveland Clinic identifies several red-flag symptoms that should prompt a visit to your healthcare provider: bloating that gets progressively worse over time, lasts longer than a week, or is persistently painful. Bloating paired with fever, vomiting, bleeding, unintentional weight loss, or signs of anemia (like unusual fatigue or paleness) also warrants evaluation, as these combinations can point to conditions beyond simple gas.
