Bloating usually comes down to one of three things: trapped gas, slow digestion, or water retention. The fix depends on which one you’re dealing with, but most people get relief from a combination of dietary changes, movement, and a few targeted remedies. Here’s what actually works.
Move Your Body First
The simplest thing you can do when you feel bloated is go for a walk. Physical activity speeds up the rate at which gas moves through your intestines, which is exactly what you need when your abdomen feels tight and distended. The Cleveland Clinic recommends aiming for 30 minutes of moderate exercise, five days a week. Moderate means your heart rate is up, you’re breaking a sweat, and you can still hold a conversation but couldn’t sing a song. Even a 10- or 15-minute walk after a meal can get things moving if a full workout isn’t realistic.
Over-the-Counter Gas Relief
Simethicone (the active ingredient in Gas-X and similar products) works by breaking up gas bubbles in your digestive tract so they’re easier to pass. The typical adult dose is 60 to 125 mg taken four times a day, after meals and at bedtime, with a maximum of 500 mg in 24 hours. It won’t prevent gas from forming, but it can take the edge off when you’re already uncomfortable.
If your bloating tends to hit after eating beans, lentils, broccoli, or other high-fiber vegetables, a digestive enzyme containing alpha-galactosidase (sold as Beano) can help. It breaks down the complex carbohydrates in those foods before they reach your large intestine, where bacteria would otherwise ferment them and produce gas. You take it with your first bite of the problem food, not after symptoms start.
Watch How You Eat, Not Just What
Eating quickly, talking while chewing, drinking through a straw, and chewing gum all increase the amount of air you swallow. That air has to go somewhere, and it often ends up sitting in your stomach or intestines. Slowing down at meals and chewing thoroughly is one of the easiest changes you can make.
Carbonated drinks are another obvious culprit. The carbon dioxide that creates the fizz releases gas directly into your digestive tract. If you’re regularly bloated and drinking sparkling water or soda throughout the day, cutting back is worth trying before anything else.
The Fiber Paradox
Fiber is essential for healthy digestion, but it can also be the reason you’re bloated. This is especially true if you’ve recently increased your fiber intake, switched to a higher-fiber cereal, or started adding a fiber supplement. Certain types of fiber are fermented by gut bacteria, and that fermentation process produces gas.
The fix isn’t to avoid fiber. It’s to increase it gradually over a few weeks so your gut bacteria can adjust. If you jumped from a low-fiber diet to a high-fiber one and started feeling worse, scale back and add a little more each week. Foods with added fiber (like fiber-enriched bars and breads) tend to cause more gas than whole foods that are naturally high in fiber.
Try a Low-FODMAP Approach
If bloating is a regular problem, certain carbohydrates in your diet may be the trigger. FODMAPs are a group of short-chain sugars that the small intestine absorbs poorly. When they pass undigested into the large intestine, bacteria ferment them, producing gas and drawing in water. Common high-FODMAP foods include garlic, onions, wheat, apples, milk, beans, and artificial sweeteners.
A low-FODMAP elimination diet, developed by researchers at Monash University, reduces symptoms in up to 86% of people according to Johns Hopkins Medicine. The process involves removing high-FODMAP foods for two to six weeks, then reintroducing them one group at a time to identify your specific triggers. It’s not meant to be a permanent diet. Most people find that only one or two FODMAP groups bother them and can eat everything else freely.
Peppermint Oil for Digestive Spasms
Peppermint oil relaxes the smooth muscle in your intestinal wall, which can ease the cramping and tightness that often accompany bloating. In a double-blind trial of 57 patients with irritable bowel syndrome, 75% of those taking enteric-coated peppermint oil capsules twice daily saw their symptom scores drop by more than half after four weeks, compared to 38% on a placebo.
The enteric coating matters. It prevents the capsule from dissolving in your stomach (which can cause heartburn) and delivers the oil to your intestines where it does the most good. You can find enteric-coated peppermint oil capsules at most pharmacies. Peppermint tea is milder and can soothe mild discomfort, but it doesn’t deliver the same concentrated dose.
Probiotics That Target Bloating
Not all probiotics help with bloating, and grabbing a random bottle off the shelf is unlikely to do much. The strains with the best evidence for reducing gas and abdominal distension are specific:
- Bifidobacterium lactis helps break down dietary fiber and digest lactose, reducing gas production at the source.
- Lactobacillus acidophilus produces lactase (the enzyme that breaks down milk sugar), making it particularly useful if dairy triggers your bloating.
- Bifidobacterium infantis has shown improvement in bloating and gas in people with IBS, and it also has anti-inflammatory effects on the intestinal lining.
- Saccharomyces boulardii is a yeast-based probiotic that’s especially helpful when bloating follows a course of antibiotics or a gut infection, since antibiotics can’t disrupt it the way they disrupt bacterial probiotics.
Probiotics typically take two to four weeks of consistent use before you notice a difference. If one strain doesn’t help after a month, it’s reasonable to try a different one.
Reduce Water Retention Bloating
Not all bloating is gas. If your abdomen feels puffy rather than pressurized, and it’s worse after salty meals or around your menstrual cycle, water retention is the more likely cause. Sodium tells your body to hold onto fluid, and potassium counteracts that effect by promoting urine production and preventing fluid buildup.
Potassium-rich foods include bananas, avocados, sweet potatoes, spinach, and white beans. Increasing your intake of these while cutting back on processed and salty foods can make a noticeable difference within a day or two. Drinking more water also helps, counterintuitive as that sounds. When you’re dehydrated, your body holds onto every drop it can. Staying well-hydrated signals your kidneys that it’s safe to release excess fluid.
Signs Your Bloating Needs Medical Attention
Most bloating is uncomfortable but harmless. It becomes worth investigating when it gets progressively worse over time, persists for more than a week, or is consistently painful rather than just annoying. The Cleveland Clinic flags several alarm symptoms that warrant a visit to your doctor: unintentional weight loss, fever, vomiting, rectal bleeding, anemia, and significant changes in bowel habits like new or worsening diarrhea or constipation. These can signal conditions like celiac disease, ovarian cysts, or inflammatory bowel disease that won’t respond to dietary tweaks alone.
