Bloating happens when gas builds up in your digestive tract, when food moves through your gut too slowly, or when the muscles in your abdominal wall relax in a way that lets your belly push outward. The good news: most bloating responds well to changes in how you eat, what you eat, and a few simple daily habits. Here’s what actually works.
Why You’re Bloating in the First Place
There are two main things going on when you feel bloated. The first is excess gas production. Bacteria in your intestines ferment carbohydrates you didn’t fully digest, and that fermentation produces gas that stretches your intestinal walls. This is especially common with certain sugars like lactose, fructose, sorbitol, and a group of carbohydrates collectively called FODMAPs.
The second is a quirk of your nervous system. Your body has a reflex that coordinates your diaphragm and abdominal wall muscles to move gas through and out of your digestive tract. In some people, this reflex misfires: the diaphragm contracts downward while the abdominal muscles relax, letting the belly protrude even when gas levels are normal. This is why two people can eat the same meal and only one ends up feeling like a balloon.
Cut Down on Swallowed Air
A surprising amount of bloating comes not from food fermentation but from air you swallow without realizing it. Cleveland Clinic identifies several everyday habits that contribute:
- Eating too fast or talking while you eat
- Chewing gum or sucking on hard candy
- Drinking through straws
- Carbonated drinks like sparkling water, soda, and beer
- Smoking
The fix is straightforward. Chew each bite slowly and swallow it before taking the next one. Sip from a glass instead of a straw. Save conversations for after the meal rather than during it. If you’re a gum chewer, this single change can make a noticeable difference within days.
Identify Your Trigger Foods
Certain short-chain carbohydrates ferment rapidly in the gut and are the most common dietary cause of bloating. These include lactose (in dairy), excess fructose (in honey, apples, and high-fructose corn syrup), sugar alcohols like sorbitol and mannitol (in sugar-free products), fructans (in wheat, onions, and garlic), and galacto-oligosaccharides (in beans and lentils).
A two-week elimination of these foods, known as a low-FODMAP approach, reduced bloating severity by 56% in clinical testing. You don’t need to avoid all of them forever. The standard process is to remove the major categories for two to six weeks, then reintroduce them one at a time. This lets you pinpoint which specific sugars your gut handles poorly and which ones you can eat without trouble. A dietitian can help you do this systematically, but many people get useful results on their own by keeping a food and symptom diary.
Get Your Fiber Right
Fiber is essential for healthy digestion, and most people don’t get enough. Current guidelines recommend about 14 grams of fiber per 1,000 calories you eat, which works out to roughly 25 to 30 grams a day for most adults. But here’s the catch: adding too much fiber too quickly is one of the most common causes of gas, cramping, and bloating.
If you’re increasing your fiber intake, whether through whole grains, vegetables, or a supplement, do it gradually over a few weeks. Add one extra serving of a high-fiber food every three to four days and give your gut bacteria time to adjust. Drinking more water as you increase fiber also helps, because fiber absorbs water and moves more smoothly through your system when it’s well hydrated.
Hormonal Bloating Before Your Period
If you notice bloating that reliably shows up in the week or so before your period, progesterone is the likely culprit. This hormone rises sharply during the second half of your menstrual cycle, and one of its effects is slowing digestion. Food sits in your gut longer, ferments more, and produces extra gas. Progesterone also contributes to water retention, which adds to that puffy, heavy feeling sometimes called “PMS belly.”
You can’t prevent the hormonal shift, but you can minimize its impact. Eating smaller, more frequent meals during that luteal phase keeps your slowed digestive system from getting overwhelmed. Reducing salt intake helps with the water retention side. Light exercise, even a 20-minute walk, stimulates gut motility and counteracts some of progesterone’s slowing effect.
Movement That Helps Right Now
When you’re already bloated and want relief, certain body positions help trapped gas move through your intestines. A few poses are particularly effective:
- Wind-relieving pose: Lie on your back and pull one or both knees into your chest. The compression on your abdomen helps you pass gas.
- Child’s pose: Kneel and fold forward with your arms extended. The gentle pressure on your stomach activates digestion.
- Seated spinal twist: Sit with legs extended, bend one knee and twist toward it. This massages your intestines and encourages movement in the digestive tract.
- Forward fold: Stand and fold at the hips, letting your upper body hang. This compresses the digestive organs and stimulates circulation.
You don’t need a full yoga session. Even five minutes cycling through these positions can help gas pass more quickly. Regular aerobic exercise, walking, cycling, or swimming, also reduces bloating over time by keeping gut motility consistent.
Probiotics That Target Bloating
Not all probiotics are equal when it comes to bloating. A systematic review published in The Lancet’s eClinicalMedicine identified specific strains with evidence behind them. One well-studied strain, Bifidobacterium infantis 35624, showed the best results at a medium dose in people with irritable bowel syndrome, with 62% of participants reporting improvement compared to 42% on placebo. Other strains with positive data include Bifidobacterium animalis DN-173010 (found in some commercial yogurt drinks) and Bacillus coagulans MTCC5856.
The key takeaway is that “probiotic” is not a single thing. If you want to try one for bloating, look for a product that lists a specific strain (the numbers after the species name matter), not just a generic “probiotic blend.” Give it at least four weeks before deciding whether it’s working.
Over-the-Counter Options
Simethicone, the active ingredient in products like Gas-X, works by breaking up gas bubbles in your digestive tract so they’re easier to pass. It doesn’t reduce gas production, but it can take the edge off that tight, distended feeling. The typical adult dose is 40 to 125 milligrams taken after meals and at bedtime.
Peppermint oil capsules are another option with genuine clinical backing. The menthol in peppermint relaxes the smooth muscle of the intestinal wall, which eases spasms and helps gas move through. It also appears to reduce visceral pain sensitivity, meaning your gut feels less uncomfortable even if gas levels stay the same. Look for enteric-coated or delayed-release capsules so the oil reaches your intestines rather than dissolving in your stomach, which can cause heartburn.
Enzyme supplements can also help in specific situations. Lactase supplements taken before dairy help if you’re lactose intolerant. Alpha-galactosidase (the enzyme in Beano) breaks down the complex sugars in beans and cruciferous vegetables before your gut bacteria get the chance to ferment them.
When Bloating Signals Something Else
Occasional bloating after a big meal or around your period is normal. Bloating that persists for weeks, keeps getting worse, or comes with unexplained weight loss, persistent pain, changes in bowel habits, or blood in your stool needs medical attention. Persistent bloating that doesn’t respond to dietary changes can sometimes signal conditions like small intestinal bacterial overgrowth, celiac disease, or, in rarer cases, ovarian cancer. The NHS specifically notes that bloating which doesn’t go away can be an early sign of ovarian cancer, particularly if it’s accompanied by feeling full quickly or pelvic pain.
