How to get rid of bloating: what helps today, and how to find your cause

How to get rid of bloating today: go for a 10 to 15 minute walk after you eat, breathe slowly into your belly, loosen your waistband, and skip fizzy drinks and gum for the evening. To bloat less often, you need to find your own cause. Change one thing for about two weeks, on the food side or the stress side, and compare those days with your usual ones.

Almost one in five people bloat every week

If your jeans feel a size smaller by 4 p.m., you have a lot of company. In a survey of more than 51,000 people in 26 countries, nearly 18% said they bloated at least once a week. Women were about twice as likely as men to say so (Ballou et al. 2023).

Bloating is that full, tight, puffed-up feeling in your belly. Sometimes you can see it too, when your belly sticks out more at dinner than it did at breakfast.

What helps with bloating fast

A short walk after eating may help with bloating

Researchers in Barcelona fed a steady stream of gas into the guts of eight people who bloated often. They did it twice: once while people lay still, and once while they pedaled gently on a bike while lying down. Lying still, 45% of the gas stayed inside. Pedaling, only 24% stayed, and people felt less bloated too (Villoria et al. 2006).

Eight people is a tiny study, and a lab bike is a long way from a stroll around the block. A walk after dinner costs nothing, so try it first.

Diaphragmatic breathing for bloating: let your belly drop

When a belly swells after a meal, muscles play a part. Your diaphragm is the dome-shaped muscle under your lungs that you breathe with. In people whose belly swells after eating, the diaphragm tends to tighten and push down while the belly wall relaxes, so the belly gets pushed out (Barba et al. 2024).

That same trial tested a way to undo it. Forty-two people whose belly swelled after meals were split into two groups. One group watched a screen that showed their breathing and learned to move their diaphragm the other way, then practiced at home three times a day for four weeks. Their belly-swelling scores dropped by 66% on average. The group given a dummy capsule saw no such drop (Barba et al. 2024).

That trial used belts, a screen and coached sessions. Plain belly breathing at home hasn't been tested, so try it as your own test:

1. Sit or lie back with one hand on your chest and one on your belly.
2. Breathe in slowly through your nose. Let the belly hand rise while the chest hand stays still.
3. Breathe out slowly, a little longer than you breathed in.
4. Keep going for about 5 minutes after a meal.

Does eating too fast cause gas?

Probably some. Each hurried gulp likely brings a little air down with the food. We couldn't find a good trial on eating speed and bloating, so this one is yours to test. Put your fork down between bites at dinner for two weeks, and watch what your evenings do.

Why am I always bloated? Find your cause, one test at a time

Try one of the ideas above on a bloated evening and see whether it helps. If you bloat most weeks, find out what sets yours off. Look at two sides: the food side (what and how much you eat) and the nervous-system side (how stress and your nerves affect your gut).

Every test works the same way:

1. Log a few normal days first, so you have something to compare against.
2. Pick one suspect and change only that, for about two weeks.
3. If you cut a food, bring it back afterward and watch for a few days.
4. Call it: helped, no change, worse or unclear.

Food side: test your suspect, then bring it back

Your first suspect might be the wrong one. In a blinded study, 59 people who believed gluten bloated them ate muesli bars for a week at a time without knowing what was in them. The bars contained gluten, fructans or neither. Fructans are plant fibers your body can't digest, so your bacteria ferment them. Bloating scores were higher after fructans. The researchers found no difference in symptoms between gluten and the plain bars (Skodje et al. 2018). Fructans are found in wheat, onion and garlic, so they're another possible suspect.

That's why every food test ends with the food coming back. If the bloating goes when the food goes, and returns when it returns, you've got a result worth keeping.

Stress side: when your stomach bloats every time you're anxious

In a study where more than 200 people with sensitive guts logged their stress and gut symptoms every day for four weeks, the two rose and fell together week by week. The study leaves cause and effect open (Blanchard et al. 2008).

Stress-side tests skip the bring-back. You compare the days you did the thing with the days you didn't.

Tests to start with

Reading your result

If logging starts to make you anxious about eating, log less or take a break. You can pick it up again later.

Let Gut Twin keep score

Gut Twin runs these tests with you. You pick meals from a food list, log how your gut feels and your poop, and run one small test at a time against your own days. It starts with a best guess at what to test first, on the food side and the stress side. Each test ends as helped, no change, worse or unclear, and every suspect stays a best guess until a test backs it up.

What we don't know yet

The walking and breathing studies were small, and both used lab equipment. The lab studies above leave open how much these ideas help in everyday life. We found no good trial on eating speed. Two weeks per test is a rule of thumb, and one home test can still give an unclear result.
