A bloated stomach usually comes down to one of three things: excess gas from fermentation in your gut, fluid your body is holding onto, or a miscommunication between your brain and digestive system that makes normal amounts of gas feel like too much. The fix depends on which one is driving your discomfort, but most people can get meaningful relief with a combination of dietary changes, physical movement, and a few targeted remedies.
Why Your Stomach Feels Bloated
The two most common triggers for bloating are bacterial overgrowth in the small intestine and intolerance to certain carbohydrates. Both lead to the same result: bacteria ferment food in your gut, producing gas that stretches your intestinal walls. Lactose, fructose, and certain fibers are frequent culprits. In one study of over 500 adults with digestive symptoms, 40% to 55% had fructose malabsorption, a condition where the small intestine can’t fully absorb the sugar before bacteria start breaking it down.
But here’s what surprises many people: some bloating has nothing to do with excess gas at all. Research from Mayo Clinic shows that many people with chronic bloating actually produce normal amounts of gas. The problem is visceral hypersensitivity, where the nerves in your gut overreact to ordinary stretching and movement. There’s also an abnormal reflex that can cause your diaphragm to push downward while your abdominal muscles relax, making your belly protrude even when gas levels are normal.
Fluid retention is the third major cause. When you eat a high-sodium meal, salt pulls water into your bloodstream, and your body parks the excess fluid in your tissues, including your abdomen. This type of bloating tends to be more diffuse and puffy rather than the tight, pressurized feeling of trapped gas.
Quick Relief for Gas and Pressure
When you need relief now, over-the-counter simethicone (sold as Gas-X or Phazyme) works by breaking up gas bubbles in your stomach and intestines so they’re easier to pass. It works best taken after meals and at bedtime. Simethicone doesn’t prevent gas from forming, so think of it as a rescue option rather than a daily strategy.
Enteric-coated peppermint oil capsules are another effective option. Peppermint relaxes the smooth muscle in your intestinal wall, which helps trapped gas move through instead of sitting in one spot and causing pain. The NHS recommends one capsule three times a day, taken 30 to 60 minutes before eating. You can increase to two capsules per dose if one isn’t enough. The enteric coating matters because it prevents the peppermint from releasing in your stomach, where it can cause heartburn.
Move the Gas Through Physically
Gentle movement is one of the fastest ways to get relief from trapped gas. You don’t need an intense workout. A 10 to 15 minute walk after eating stimulates the muscles of your digestive tract and helps gas travel toward the exit.
Specific yoga poses work even better because they combine compression and release with gravitational changes that encourage gas to move. The wind-relieving pose (lying on your back and pulling one or both knees to your chest) is the most direct. It compresses the intestines and relaxes the muscles around your bowels, making it easier to pass gas. Seated spinal twists massage the intestines and increase blood flow to the digestive tract. Child’s pose applies light pressure to your stomach. Even a simple forward fold, standing and bending at the waist, compresses the digestive organs and stimulates circulation.
Try holding each pose for 30 seconds to a minute, breathing deeply. The combination of compression and deep breathing seems to help activate the reflex that clears gas from the intestines.
Adjust What You Eat
If bloating is a regular problem, your diet is the most powerful lever you have. Start by identifying your triggers. The most common offenders are dairy (lactose), fruits and sweeteners high in fructose, beans, cruciferous vegetables like broccoli and cabbage, onions, garlic, and carbonated drinks. You don’t need to cut everything at once. Try removing one category for two to three weeks and see if your symptoms improve.
Fiber is tricky because it’s essential for digestion but also a major bloating trigger, especially when you increase your intake too quickly. The daily target is 25 grams for women and 38 grams for men under 50. If you’re well below that and want to increase, add about 2 to 3 grams per week to give your gut bacteria time to adjust. Soluble fiber (found in oats, beans, and apples) dissolves in water and forms a gel that slows digestion. Insoluble fiber (found in whole wheat, nuts, and vegetables) adds bulk and speeds transit. Both can produce gas, but soluble fiber tends to cause more fermentation. Spacing fiber throughout the day rather than loading it into one meal also helps.
Eating too fast is an overlooked cause. When you gulp food, you swallow air, and that air has to go somewhere. Chewing slowly and putting your fork down between bites sounds simplistic, but it genuinely reduces the volume of air entering your digestive tract.
Fix Fluid-Related Bloating
If your bloating feels more like puffiness than pressure, and it gets worse after salty meals or around your menstrual cycle, fluid retention is likely involved. The fix is adjusting your sodium-to-potassium balance. Sodium holds water in your tissues, while potassium helps your body flush sodium out.
During a bloated stretch, aim for under 2,000 mg of sodium per day. That means watching processed foods, restaurant meals, canned soups, and deli meats, which are where most dietary sodium hides. At the same time, increase potassium-rich foods: bananas, avocados, sweet potatoes, spinach, and white beans. Most adults do well near 3,500 to 4,700 mg of potassium daily from food.
Drinking more water, not less, also helps. It sounds counterintuitive, but when you’re dehydrated your body holds onto fluid more aggressively. Consistent hydration signals that it’s safe to release stored water.
Probiotics That Actually Help
Not all probiotics reduce bloating, and most over-the-counter blends haven’t been tested for it. The strain with the strongest evidence is Bifidobacterium infantis 35624, which was tested in a clinical trial published in the Lancet system and showed consistent reductions in bloating scores compared to placebo across multiple doses. Another strain, Bifidobacterium animalis DN-173010 (the one found in certain fermented dairy drinks), also showed improvements in bloating in clinical trials.
The key word is “strain.” A product labeled simply “Bifidobacterium” without a specific strain number may not contain the version that was actually studied. Look for the full strain name on the label. Give any probiotic at least four weeks before judging whether it’s working, since your gut microbiome needs time to shift.
When Bloating Signals Something Bigger
Most bloating is uncomfortable but harmless. It becomes concerning when it’s accompanied by unintentional weight loss, persistent vomiting, fever, blood in your stool, or anemia. Bloating that gets progressively worse over weeks, persists for more than a week without relief, or causes constant pain rather than intermittent discomfort also warrants investigation. These patterns can point to conditions like celiac disease, ovarian issues, gastroparesis (where the stomach empties too slowly), or in rare cases, malignancy. A hydrogen breath test can identify fructose or lactose malabsorption, and testing for small intestinal bacterial overgrowth is straightforward if your doctor suspects it.
