Bloating usually comes down to one of two things: excess gas trapped in your intestines, or your body holding onto extra water. The fix depends on which one is driving your discomfort, and sometimes it’s both at once. The good news is that most bloating responds well to simple changes you can start today.
Why You’re Bloated in the First Place
Your gut bacteria produce gas as they break down carbohydrates in a process called fermentation. This is normal. But when too many carbohydrates slip through your upper digestive tract without being absorbed, bacteria in your lower gut go into overdrive, producing more gas than your body can comfortably handle. That pressure creates the tight, swollen feeling in your abdomen.
Water retention is the other common culprit. Hormonal shifts, particularly rising estrogen and dropping progesterone before a period, cause your body to hold onto fluid. High sodium intake does the same thing. A study from Johns Hopkins found that high-sodium diets increased the risk of bloating by about 27 percent compared to low-sodium versions of the same diet. So that salty takeout dinner really can leave you puffy the next morning.
You can also end up bloated simply from swallowing too much air, a condition called aerophagia. Chewing gum, drinking through straws, eating too fast, and talking while you eat all force air into your gut, where it gets trapped and creates visible swelling.
Quick Relief for Gas-Related Bloating
When you need relief now, movement is your best friend. A 15 to 20 minute walk stimulates the muscles in your digestive tract and helps gas move through. You don’t need to power walk. A gentle stroll after a meal is enough to get things moving.
Specific yoga poses work well too. The wind-relieving pose (lying on your back and pulling one knee to your chest) compresses your intestines and helps you pass trapped gas. Seated spinal twists massage your abdominal organs and increase blood flow to your digestive tract. A simple child’s pose applies light pressure to your stomach that can activate sluggish digestion. Even five minutes of these positions can bring noticeable relief.
Peppermint oil in enteric-coated capsules relaxes the smooth muscle in your intestines, which lets trapped gas pass more easily. In a double-blind trial, 75 percent of participants taking peppermint oil capsules twice daily saw more than a 50 percent reduction in digestive symptoms after four weeks, compared to 38 percent on placebo. Look for enteric-coated versions specifically, since the coating prevents the oil from dissolving in your stomach and instead delivers it to your intestines where it’s needed.
Over-the-counter gas relief products containing simethicone work by breaking up gas bubbles so they’re easier to pass. The typical adult dose is 60 to 125 mg taken after meals and at bedtime, with a maximum of 500 mg in 24 hours. Simethicone won’t prevent new gas from forming, but it can take the edge off when you’re already uncomfortable.
Reduce Water Retention Fast
If your bloating feels more like puffiness than pressure, water retention is likely the issue. Counterintuitively, drinking more water helps. When you’re dehydrated, your body holds onto every drop it can. Staying well-hydrated signals your kidneys to release excess fluid.
Cut your sodium intake for a day or two. Processed foods, restaurant meals, canned soups, and deli meats are the biggest sodium sources for most people. Swapping these for whole foods with natural potassium, like bananas, avocados, and sweet potatoes, helps your body rebalance its fluid levels. Potassium acts as a counterweight to sodium, encouraging your kidneys to flush the extra water.
For hormonal bloating tied to your menstrual cycle, the same strategies apply. Reducing salt intake in the days before your period and staying hydrated can meaningfully reduce that premenstrual puffiness.
Dietary Changes That Prevent Bloating
A low-FODMAP diet is one of the most effective approaches for recurring bloating. FODMAPs are specific types of carbohydrates that ferment rapidly in your gut: things like onions, garlic, wheat, beans, certain fruits, and dairy products containing lactose. Research from Johns Hopkins Medicine found this diet reduces digestive symptoms in up to 86 percent of people. The approach works in three phases: you eliminate high-FODMAP foods for two to six weeks, then reintroduce them one category at a time to identify your personal triggers, and finally settle into a long-term diet that avoids only the foods that bother you.
Fiber is essential for healthy digestion, but adding too much too quickly is one of the most common causes of bloating. If you’re increasing your fiber intake, add no more than 5 grams per day and drink plenty of water alongside it. Water helps fiber move through your system rather than sitting in your gut and fermenting. A sudden jump from 10 grams to 30 grams of daily fiber will almost guarantee a few miserable days.
Carbonated drinks deliver gas directly into your digestive tract. Sparkling water, beer, and soda can all contribute to bloating, especially if you’re already prone to it. Artificial sweeteners like sorbitol and mannitol, commonly found in sugar-free gum and candy, are also poorly absorbed and ferment in the gut the same way FODMAPs do.
Habits That Make a Difference
How you eat matters almost as much as what you eat. Eating slowly and chewing thoroughly gives your upper digestive tract more time to break down food before it reaches the bacteria in your lower gut. When you rush through meals, larger food particles arrive undigested, giving gut bacteria more material to ferment.
Smaller, more frequent meals put less strain on your digestive system at any one time. A large meal stretches your stomach and slows the rate at which food moves through, which gives bacteria more time to produce gas. Splitting the same amount of food across four or five smaller meals can reduce post-meal bloating significantly.
If you chew gum regularly, this is worth reconsidering. The repetitive chewing motion causes you to swallow air continuously, and many gums contain sugar alcohols that contribute to fermentation. It’s a double hit.
Probiotics for Longer-Term Relief
Certain probiotic strains can help rebalance the bacteria in your gut so they produce less gas over time. The strain with the strongest evidence for bloating is Bifidobacterium infantis 35624, which has been tested across multiple clinical trials. In one study, 62 percent of participants on a medium dose experienced global symptom improvement, compared to 42 percent on placebo. Other strains with supporting evidence include Bifidobacterium animalis and Bacillus coagulans.
Probiotics aren’t instant relief. Most trials run four to eight weeks before measuring results, so give them time. Look for products that list the specific strain (not just the species) on the label, since closely related strains can have very different effects.
When Bloating Signals Something Bigger
Most bloating is harmless, but certain patterns warrant attention. Persistent bloating that doesn’t respond to dietary changes, bloating paired with unintentional weight loss of 10 percent or more, recurring nausea and vomiting, blood in your stool, or unexplained anemia are all signals that something beyond routine gas or water retention may be going on. A gradual buildup of fluid in the abdomen, called ascites, can be caused by liver disease, kidney failure, or heart failure, and feels different from typical bloating because it doesn’t fluctuate with meals or time of day. If your abdomen stays visibly distended regardless of what or when you eat, that’s worth investigating.
