A bloated stomach usually comes from excess gas, fluid retention, or slow-moving digestion, and each cause has a different fix. The good news is that most bloating responds well to simple changes you can start today. Here’s what actually works, organized from quick relief to longer-term strategies.
Quick Physical Relief
When you’re bloated right now, gentle movement is one of the fastest ways to get things moving. A short walk after eating helps stimulate the muscles that push gas through your digestive tract. If walking isn’t an option, specific body positions can help. Lying on your back and pulling your knees to your chest (sometimes called the “wind-relieving pose” for good reason) puts gentle pressure on your abdomen and helps trapped gas shift. Twisting at the waist while lying down compresses the intestines and encourages gas to pass. Bridge pose, where you lie on your back and lift your hips, alternately compresses and releases the abdominal area, improving blood flow and helping release gas.
The common thread: moves that involve twisting your midsection, forward bends, squats, and knees-to-chest positions all mechanically encourage gas to travel through and out of your digestive tract. They also lower stress, which makes it physically easier for your body to relax and release gas. Even five minutes of these positions can make a noticeable difference.
Over-the-Counter Gas Relief
Simethicone (sold as Gas-X and similar brands) works by breaking up gas bubbles in your gut so they’re easier to pass. It’s taken after meals and at bedtime, up to four times a day. It won’t prevent gas from forming, but it can reduce that uncomfortable pressure feeling relatively quickly.
Peppermint oil capsules are another option, particularly if your bloating comes with cramping. The capsules need to be enteric-coated, meaning they’re designed to dissolve in your intestines rather than your stomach. 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. Swallow them whole with water. Breaking or chewing them releases the oil in your stomach, which can cause heartburn instead of relief.
Stop Swallowing So Much Air
A surprising amount of bloating comes not from what you eat, but from air you swallow without realizing it. This is called aerophagia, and common culprits include eating too fast, talking while eating, chewing gum, sucking on hard candy, drinking through straws, and carbonated beverages. Smoking and loose-fitting dentures also contribute. Stress and anxiety increase air swallowing too, because tense breathing patterns pull more air into the esophagus.
The fix is straightforward: chew your food slowly and make sure you’ve swallowed one bite before taking the next. Put your fork down between bites. Skip the straw. If you’re a gum chewer or hard candy person, cutting back may noticeably reduce how bloated you feel by the end of each day.
Identify Your Trigger Foods
Not all fiber is created equal when it comes to gas production. Soluble fibers that ferment easily in your gut are the biggest gas producers. Your gut bacteria break these fibers down, and the byproducts include gas. The most fermentable types include inulin and oligofructose (found naturally in onions and Jerusalem artichokes), beta-glucans from oats and barley, resistant starches in bananas and legumes, and wheat dextrin. These fibers are genuinely healthy and feed beneficial gut bacteria, but if you’re sensitive, they can cause significant bloating.
A low-FODMAP diet, which temporarily removes these highly fermentable carbohydrates, has strong evidence behind it. In a study published in Frontiers in Nutrition, over 90% of IBS patients reported a reduction in symptoms after following the diet. The approach works in three phases: you eliminate high-FODMAP foods for two to six weeks, then systematically reintroduce them one category at a time to identify your personal triggers, and finally settle into a long-term diet that avoids only the specific foods that bother you. Common triggers include garlic, onions, wheat, certain fruits, and dairy, but everyone’s list is different.
If you’re adding more fiber to your diet for health reasons, increase gradually. A sudden jump in fiber intake overwhelms your gut bacteria and produces a surge of gas. Spreading the increase over two to three weeks gives your microbiome time to adjust.
Reduce Water Retention
Not all bloating is gas. Sometimes your belly feels swollen because your body is holding onto extra fluid, and sodium is usually the driver. Salt pulls water into your bloodstream, and to keep your blood from getting too concentrated, your body parks excess fluid in your tissues, including your abdomen.
Potassium helps counteract this by encouraging your body to push out sodium. Most adults do well near 3,500 to 4,700 mg of potassium per day from food. You don’t need supplements to get there. One cup of cooked spinach delivers about 800 mg, a cup of cooked potatoes around 600 mg, a cup of plain yogurt about 570 mg, and a medium banana roughly 420 mg. Building a few of these into your daily meals can meaningfully reduce fluid-related bloating, especially if your diet is currently heavy on processed or salty foods.
Drinking more water, counterintuitively, also helps. When you’re dehydrated, your body holds onto fluid more aggressively. Staying well-hydrated signals that it’s safe to let go of the excess.
Probiotics for Ongoing Bloating
Probiotics may help if your bloating is chronic, though the evidence is strain-specific and modest. One clinical trial tested Bifidobacterium infantis 35624 at one billion colony-forming units per day and found significantly more bloating-free days compared to placebo. That said, the same study noted the improvement was less dramatic in people without an underlying condition like IBS. Probiotics aren’t a quick fix. They typically take several weeks of consistent use before you’d notice a difference, and what works varies from person to person.
When Bloating Signals Something Else
Most bloating is harmless, but certain patterns warrant attention. Bloating that gets progressively worse over time, persists for more than a week, or comes with persistent pain is worth investigating. The Cleveland Clinic flags accompanying symptoms like unexplained weight loss, fever, vomiting, bleeding, anemia, or significant changes in bowel habits (new diarrhea or constipation) as red flags that point to something beyond simple gas or fluid retention. These combinations can indicate conditions ranging from food intolerances to ovarian issues to inflammatory bowel disease, all of which are treatable but need proper diagnosis.
