Most bloating comes down to one of two things: trapped gas in your digestive tract or water your body is holding onto after too much sodium. The fix depends on which type you’re dealing with, but several strategies work for both. Here’s what actually helps, from quick relief to longer-term changes.
Take a Short Walk After Eating
One of the simplest and most effective things you can do is walk for 10 to 15 minutes after a meal. A clinical trial found that this brief post-meal walk significantly improved bloating, gas, belching, and abdominal discomfort. The walking helps your intestines move gas through and out of your system faster. You don’t need to power walk. Slow, relaxed walking (about 1,000 steps) is enough to make a noticeable difference.
Try an Abdominal Self-Massage
If you’re lying on the couch feeling bloated, a technique called the ILU massage can help move trapped gas along the natural path of your large intestine. Your colon is shaped like an upside-down U, running up your right side, across the top of your abdomen, and down your left side. The massage follows that route to push gas and stool toward the exit.
Lie on your back and start with the “I” stroke: place your hand just under your left rib cage and slide it straight down toward your left hip. Repeat 10 times with gentle pressure. Next, the “L” stroke: start below your right rib cage, move across to the left, then down to your left hip. Repeat 10 times. Finally, the full “U” stroke: start at your right hip, go up to your right ribs, across to your left ribs, and down to your left hip. Repeat 10 times. Finish with small clockwise circles around your belly button for a minute or two.
Eat More Potassium, Less Sodium
If your bloating feels more like puffiness or tightness (especially after salty food), you’re likely retaining water. Sodium pulls water outside your cells, where it sits as visible swelling. Potassium works like a counterbalance: it helps your kidneys flush sodium and excess water out through urine. When potassium intake is adequate, your body can push more sodium out rather than storing it.
A banana, half an avocado, or a handful of spinach with your next meal can start shifting that balance. Think of sodium and potassium as a seesaw. If you had a salty dinner, pairing the next day’s breakfast with potassium-rich foods helps your body let go of the extra fluid naturally.
Identify Your Trigger Foods
Certain carbohydrates are poorly absorbed in the small intestine and end up being fermented by gut bacteria, which produces gas. These are collectively called FODMAPs, and they include four main groups:
- Oligosaccharides: found in onions, garlic, beans, lentils, and many wheat products
- Lactose: the sugar in milk and dairy
- Fructose: the sugar in certain fruits, especially apples, watermelon, and stone fruits like peaches and plums
- Sugar alcohols: used as artificial sweeteners and found naturally in some fruits
If you suspect one of these groups is behind your bloating, a low-FODMAP elimination diet can help you figure it out. You remove all high-FODMAP foods for two to six weeks, then add them back one group at a time. Most people notice improvement within two to four weeks. It’s not meant to be permanent. The goal is to identify which specific foods cause problems for you, so you can eat everything else freely. Grapes, strawberries, and pineapples, for example, are low-FODMAP fruits that rarely cause issues.
Manage Fiber Carefully
Fiber is essential for healthy digestion, and getting enough of it prevents constipation-related bloating by adding bulk and softness to stool. But the wrong type or a sudden increase can make bloating worse. Soluble fiber dissolves in water and forms a gel-like material that slows digestion. It’s generally gentler. Insoluble fiber adds bulk but can produce more gas, especially when your gut isn’t used to it.
Processed “added fiber” ingredients like chicory root (often listed as inulin on labels) are particularly common culprits. They show up in protein bars, high-fiber cereals, and low-calorie snacks, and many people report gas after eating them. If you’re increasing your fiber intake, do it gradually over a couple of weeks so your gut bacteria can adjust.
Consider Probiotics
Certain probiotic strains can reduce bloating by shifting the balance of bacteria in your gut toward species that produce less gas. Research evaluating specific strains found that Bifidobacterium bifidum showed the best individual results at a dose of 1 billion colony-forming units daily for four weeks. A combination of Lactobacillus, Bifidobacterium, and Streptococcus strains also performed well over the same timeframe. Probiotics aren’t instant relief. They typically take a few weeks of consistent use before you notice a change.
Over-the-Counter Options
Two types of OTC products target gas-related bloating in different ways. Simethicone is an antifoaming agent that breaks up gas bubbles in your digestive tract, making them easier to pass. It works quickly and is useful for acute discomfort after a meal.
Alpha-galactosidase (sold as Beano) takes a different approach. It’s an enzyme that breaks down the complex carbohydrates in beans, lentils, and certain vegetables before they reach your large intestine, preventing the fermentation that creates gas in the first place. You take it with your first bite of the trigger food, not after symptoms start.
Peppermint Oil for Persistent Bloating
Enteric-coated peppermint oil capsules relax the smooth muscle lining your intestines by blocking calcium channels in the muscle cells. This reduces the cramping and spasms that can trap gas and cause that tight, distended feeling. The enteric coating is important because it allows about 70% of the oil to reach the colon rather than being released in the stomach, where it can cause heartburn. This option is particularly well-studied in people with irritable bowel syndrome, but the muscle-relaxing mechanism is relevant for anyone dealing with recurrent bloating and cramping.
Drink Water Normally
A persistent myth suggests that drinking water with meals dilutes your digestive enzymes and worsens bloating. This isn’t true. Water is a component of stomach acid itself and actually helps break down food so your body can absorb nutrients more efficiently. Drinking water with meals also helps you feel full without extra calories, which can prevent the overeating that leads to bloating in the first place. Stay hydrated throughout the day, including at meals.
When Bloating Signals Something Else
Occasional bloating after a big meal or a salty day is normal. But bloating that comes with unintended weight loss, blood in your stool, or unexplained anemia points to something that needs investigation. Persistent bloating that doesn’t respond to any of the strategies above, especially if it’s a new symptom or has been gradually worsening, is worth bringing to a doctor’s attention.
