Bloating usually comes from trapped gas, slowed digestion, or water retention, and most cases respond well to simple changes you can start today. The fix depends on what’s driving the problem, so it helps to understand the most likely culprits before reaching for remedies.
Why You’re Bloated in the First Place
The most common causes of abdominal bloating are swallowing air (from eating too fast, chewing gum, or drinking through straws), constipation, overeating, and difficulty digesting certain foods like dairy or wheat. Irritable bowel syndrome (IBS) and an overgrowth of bacteria in the small intestine can also keep your belly distended for hours or days at a time.
A less obvious trigger is salt. 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. Salt causes your body to hold onto water, and that extra fluid can settle in your abdomen. If your bloating tends to show up after restaurant meals or processed foods, sodium is a likely contributor.
Certain carbohydrates called FODMAPs are also major gas producers. These are sugars that ferment in your gut, and they’re found in surprisingly common foods: onions, garlic, apples, pears, beans, wheat bread, and dairy. For many people, one or two of these foods are the hidden source of daily bloating.
Quick Relief for Bloating Right Now
If you’re bloated and uncomfortable, a few things can help within minutes to hours. Light physical activity after eating encourages your digestive tract to move gas through. Even a 10 to 15 minute walk can make a noticeable difference.
Specific body positions also help release trapped gas. Lying on your back and pulling both knees to your chest (called the wind-relieving pose) compresses the abdomen and helps you pass gas. Other effective positions include child’s pose, a seated forward bend, and lying flat while twisting both knees to one side. You can also try abdominal self-massage: lie on your back and rub your belly in a clockwise direction, following the path of your colon, using gentle pressure with your palm or a loose fist.
Over-the-counter gas relief products containing simethicone work by breaking up gas bubbles in your stomach and intestines, making them easier to pass. These are taken after meals. If your bloating comes specifically from beans, lentils, or cruciferous vegetables, enzyme supplements designed to break down those complex sugars before they ferment can help when taken with the first bite of food.
Dietary Changes That Make the Biggest Difference
A low-FODMAP diet is one of the most studied approaches to chronic bloating. Research from Johns Hopkins Medicine found it reduces symptoms in up to 86 percent of people. The diet works by temporarily removing the fermentable carbohydrates that feed gas-producing gut bacteria, then reintroducing them one at a time to identify your personal triggers.
The main foods to cut during an elimination phase include:
- Dairy: milk, yogurt, and ice cream
- Wheat-based products: bread, cereal, and crackers
- Beans and lentils
- Certain vegetables: artichokes, asparagus, onions, and garlic
- Certain fruits: apples, cherries, pears, and peaches
You don’t need to avoid all of these forever. The point is to strip them out for two to six weeks, then add them back one category at a time. Most people find that only one or two groups are real problems for them.
Fiber is helpful for bloating caused by constipation, but increasing it too quickly can backfire and make gas worse. Start with something simple like one bowl of oatmeal per day and give your gut time to adjust before adding more. If bloating gets worse instead of better, scale back.
Reducing sodium is another straightforward lever. Cooking more meals at home and cutting back on packaged snacks, deli meats, and soy sauce can meaningfully reduce water-retention bloating within a few days.
Peppermint Oil for Ongoing Bloating
Enteric-coated peppermint oil capsules have solid clinical evidence behind them. In a double-blind trial of IBS patients, 75 percent of those taking peppermint oil saw more than a 50 percent reduction in their overall symptom score after four weeks, compared to 38 percent in the placebo group. The benefit also persisted for at least a month after stopping. The enteric coating matters because it prevents the oil from releasing in the stomach (which can cause heartburn) and delivers it to the intestines where it relaxes smooth muscle and reduces spasms that trap gas.
Probiotics That Target Bloating
Not all probiotics help with bloating, but specific strains have clinical evidence. Bifidobacterium infantis 35624 is one of the best studied. In a trial of women with IBS, it significantly reduced both abdominal pain and bloating across all IBS subtypes. Other strains with positive results include Lactobacillus rhamnosus IDCC 3201, which improved bloating and bowel habits over eight weeks, and heat-inactivated Bifidobacterium bifidum MIMBb75, which improved bloating along with overall IBS symptoms.
The key takeaway with probiotics is specificity. A generic “gut health” blend from the supplement aisle may contain none of these strains. Look for products that list the exact strain name and number on the label, not just the species. Most effective doses in studies were around 1 to 10 billion colony-forming units taken daily for at least four weeks before judging results.
Habits That Prevent Bloating From Coming Back
Eating slowly and chewing thoroughly reduces the amount of air you swallow, which is one of the simplest and most overlooked causes of gas. Smaller, more frequent meals also keep your digestive system from being overwhelmed. Carbonated drinks introduce gas directly into your stomach, so cutting back on sparkling water, beer, and soda can help.
Regular physical activity keeps your gut motility healthy, meaning food and gas move through at a normal pace instead of sitting and fermenting. You don’t need intense exercise. Consistent daily movement, even walking, is enough to make a difference over time.
Signs Your Bloating Needs Medical Attention
Most bloating is uncomfortable but harmless. However, you should see a healthcare provider if your bloating gets progressively worse over time, lasts more than a week without improvement, or comes with persistent pain. Bloating paired with fever, vomiting, blood in your stool, unexplained weight loss, or signs of anemia (like unusual fatigue or pale skin) warrants prompt evaluation, as these can signal conditions beyond simple gas or food intolerance.
