Bloating usually comes from one of two things: trapped gas in your intestines or fluid your body is holding onto. The good news is that most episodes resolve within a few hours, and several strategies can speed that process along. What works fastest depends on which type of bloating you’re dealing with.
Why You’re Bloated Right Now
Most bloating happens when bacteria in your gut ferment carbohydrates that weren’t fully absorbed earlier in digestion. That fermentation produces gas, which stretches your intestinal walls. The more undigested carbs that reach your lower gut, the more gas you get. Common triggers include beans, lentils, dairy, wheat, onions, garlic, and certain fruits like apples, pears, and cherries.
But here’s something worth knowing: some people who feel severely bloated are actually producing a normal amount of gas. The issue is heightened sensitivity in the gut nerves, which makes ordinary gas feel like intense pressure. In other cases, the muscles of the diaphragm and abdominal wall respond abnormally to gas, contracting or relaxing in ways that push the belly outward even when gas volume is modest.
Fluid-based bloating is a separate issue. A high-sodium meal, hormonal shifts (especially drops in progesterone paired with rising estrogen), or simply not drinking enough water can all cause your body to retain fluid in the abdomen and elsewhere.
Get Moving Within Minutes
A short walk is one of the fastest things you can do. A 2021 study found that people who walked for 10 to 15 minutes after eating reported noticeably less bloating. Walking stimulates the muscles of your digestive tract, helping gas move through and out rather than sitting in one place.
If you can’t walk, certain body positions help gas travel toward the exit. Lying on your back and pulling your knees to your chest stretches the lower back and hips, creating gentle abdominal pressure that encourages gas to pass. Child’s pose (kneeling with your torso folded forward over your thighs) works similarly by relaxing the hips and lower back. A deep squat, where your feet are flat on the floor and your hips drop below your knees, opens the pelvic floor and can provide quick relief. Lying twists, where you drop both knees to one side while keeping your shoulders flat, stretch the lower back and help rotate trapped gas through the colon.
You can also massage your abdomen in a clockwise direction, moving from right to left. This follows the natural path of your colon and can physically nudge gas along.
Over-the-Counter Gas Relief
Simethicone (the active ingredient in Gas-X and similar products) works by breaking large gas bubbles into smaller ones, making them easier to pass. It’s taken after meals, typically 40 to 125 mg up to four times a day. If you’re using chewable tablets, chew them thoroughly before swallowing, as this helps the medication work faster. Simethicone doesn’t prevent gas from forming, but it can reduce that stretched, pressurized feeling more quickly than waiting it out.
For gas caused specifically by beans, lentils, or certain vegetables, a digestive enzyme supplement containing alpha-galactosidase (sold as Beano) can help. It breaks down the complex carbohydrates that your gut bacteria would otherwise ferment into gas. The key is timing: you need to take it before or at the start of a meal, not after bloating has already set in. More than 20% of people experience gas-related abdominal pain from these foods, so if beans are a regular trigger, keeping these on hand is practical.
If dairy is the culprit, a lactase supplement works on the same principle, breaking down the milk sugar your body can’t handle before it reaches the bacteria that ferment it.
Peppermint Oil for Muscle Relaxation
Enteric-coated peppermint oil capsules relax the smooth muscle lining your digestive tract. This eases cramping and allows gas to pass more freely rather than getting trapped behind spasming sections of intestine. The coating is important because it prevents the capsule from dissolving in your stomach (which can cause heartburn) and delivers the oil to your intestines where it’s needed. Most clinical trials used doses of 0.2 to 0.4 mL taken three times daily. Peppermint tea can provide milder relief, though it’s less targeted than the capsules.
Reduce Fluid-Based Bloating
If your bloating feels more like puffiness than pressure, and especially if it follows a salty meal or coincides with your menstrual cycle, you’re likely retaining water. Counterintuitively, drinking more water helps. When you’re dehydrated, your body holds onto fluid more aggressively.
Potassium-rich foods counteract excess sodium by helping your kidneys flush it out, increasing urine production and reducing fluid buildup. Bananas, avocados, and tomatoes are among the best sources. Cutting back on sodium for the rest of the day also helps your body release the water it’s holding. Most people notice fluid-based bloating improving within several hours to a day once they address the sodium-potassium balance.
Prevent the Next Episode
Speed of eating matters more than most people realize. When you eat quickly, you swallow extra air, and you send larger, less-digested food particles to your gut bacteria. Making your meal last at least 20 minutes gives your stomach and small intestine time to break down food properly before it reaches the gas-producing bacteria further along.
The foods most likely to trigger rapid fermentation and bloating fall into a category called FODMAPs: poorly absorbed short-chain carbohydrates. The biggest offenders include dairy (milk, yogurt, ice cream), wheat-based bread and cereals, beans and lentils, onions, garlic, asparagus, artichokes, apples, pears, cherries, and peaches. You don’t necessarily need to avoid all of these permanently, but if bloating is a recurring problem, eliminating these foods for two to three weeks and reintroducing them one at a time can help you identify your specific triggers.
Carbonated drinks are another straightforward cause. Every sip delivers dissolved gas directly into your stomach.
When Bloating Signals Something Else
Occasional bloating after a large meal or a known trigger food is normal. Bloating that persists for more than a few days, comes with unexplained weight loss, involves blood in your stool, or is accompanied by severe abdominal pain that doesn’t resolve is different. A gradual buildup of fluid in the abdomen (called ascites) can mimic bloating but is typically caused by liver, kidney, or heart problems and produces a steady increase in abdominal size rather than the fluctuating fullness of gas. Persistent bloating paired with changes in bowel habits, loss of appetite, or feeling full after eating very little also warrants attention.
