Bloating usually comes down to one of three things: excess gas from food fermentation, swallowed air, or water retention. The fix depends on which one is driving your discomfort, and for many people, it’s a combination. The good news is that most bloating responds well to straightforward changes in what you eat, how you eat, and how you move.
Cut the Foods Most Likely to Cause It
Certain carbohydrates are poorly absorbed in the small intestine. When they reach the large intestine intact, gut bacteria ferment them and produce gas. These fermentable carbohydrates go by the acronym FODMAPs, and they’re the single most common dietary trigger for bloating. The major culprits include dairy-based milk, yogurt, and ice cream; wheat-based products like bread, cereal, and crackers; beans and lentils; vegetables such as onions, garlic, asparagus, and artichokes; and fruits like apples, cherries, pears, and peaches.
You don’t necessarily need to eliminate all of these permanently. A temporary elimination approach, where you cut high-FODMAP foods for two to six weeks and then reintroduce them one at a time, helps you identify which specific foods your gut reacts to. Most people find they’re sensitive to a handful of items, not the entire list.
Carbonated drinks deserve a separate mention. They deliver carbon dioxide directly into your stomach, and for some people that alone is enough to cause visible distension.
Stop Swallowing So Much Air
Every time you eat, drink, or even talk, some air enters your stomach. That’s normal. But certain habits dramatically increase the volume. Eating too fast, talking while chewing, chewing gum, sucking on hard candy, drinking through straws, and smoking all contribute to excess air swallowing, a condition called aerophagia.
The fixes are simple. Chew each bite of food 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. Skip the gum and hard candies entirely if bloating is a regular problem for you. These changes alone can noticeably reduce the amount of gas that builds up in your digestive tract over the course of a day.
Move Your Body to Move the Gas
Physical activity helps gas travel through your intestines and exit rather than sitting in one place and expanding. Even a 10- to 15-minute walk after eating can make a difference. For more targeted relief, specific yoga poses work well because they compress and massage the abdomen.
Wind-relieving pose (lying on your back and pulling your knees to your chest) is the classic choice for a reason: it relaxes the abdomen, hips, and thighs and encourages trapped gas to pass. Child’s pose gently compresses your internal organs. A two-knee spinal twist, where you lie on your back and drop both bent knees to one side, stretches and stimulates the digestive tract. Happy baby pose (grabbing the outsides of your feet while lying on your back) stretches the lower back and inner groin while calming the nervous system, which can ease tension-related bloating.
Hold each pose for 30 seconds to a minute and breathe deeply. You can cycle through all four in under 10 minutes.
Manage Fiber Carefully
Fiber is essential for digestion, but it’s also a common source of bloating, especially when you increase your intake too quickly. Soluble fiber dissolves in water and forms a gel-like material in the stomach that slows digestion. Insoluble fiber doesn’t dissolve and instead adds bulk to stool and keeps things moving. Both types are fermented to some degree by gut bacteria, which means both can produce gas.
If you’re adding more fruits, vegetables, whole grains, or supplements to your diet, increase the amount gradually over several weeks. This gives your gut bacteria time to adjust. Jumping from a low-fiber diet to a high-fiber one overnight is one of the fastest ways to trigger severe bloating and cramping.
Consider Over-the-Counter Options
Simethicone is the most widely available anti-gas medication. It works by breaking up gas bubbles in your gut so they’re easier to pass. The typical adult dose is 40 to 125 mg taken four times a day (after meals and at bedtime), with a maximum of 500 mg in 24 hours. It’s generally well tolerated and works best for bloating caused by trapped gas rather than water retention.
If beans and legumes are your main trigger, digestive enzyme supplements containing alpha-galactosidase (sold under brand names like Beano) can help break down the complex carbohydrates that cause fermentation. One caveat: stomach acid can degrade the enzyme before it does its job. Research shows that taking it alongside protein-containing foods helps protect the enzyme’s activity through digestion. So taking it with a full meal, rather than on an empty stomach, improves its effectiveness.
Enteric-coated peppermint oil capsules have solid evidence behind them. In one clinical trial, 64% of people taking peppermint oil experienced at least a 50% reduction in total digestive symptoms after four weeks, compared to 34% on placebo. The enteric coating is important because it prevents the peppermint oil from releasing in the stomach (which can cause heartburn) and delivers it to the intestines where it relaxes smooth muscle and reduces spasms.
Probiotics That Actually Help
Not all probiotics are equal when it comes to bloating. A systematic review published in The Lancet’s eClinicalMedicine identified specific strains with clinical evidence behind them. Lactobacillus plantarum 299v and Bifidobacterium infantis 35624 both showed meaningful improvements in abdominal symptoms including pain and bloating. Six single-strain probiotics and three probiotic mixtures demonstrated significant benefits for at least one measure of gut symptoms in clinical trials.
Look for products that list the specific strain on the label (not just the species name) and check that the strain matches one with clinical evidence. A generic “probiotic blend” with no strain information is a gamble. Give any probiotic at least four weeks before deciding whether it’s working for you.
Hormonal Bloating Before Your Period
If your bloating follows a predictable pattern tied to your menstrual cycle, hormones are likely involved. During the late luteal phase (the week or so before your period), progesterone and estrogen levels shift in ways that increase fluid retention. Progesterone increases capillary permeability, allowing fluid and proteins to leak from blood vessels into surrounding tissue. This is why you may notice swelling in your ankles, breasts, and abdomen during that window.
Your body also ramps up production of aldosterone, a hormone that tells your kidneys to hold onto sodium and water. Women who experience premenstrual syndrome tend to have exaggerated spikes in aldosterone compared to those who don’t, which helps explain why the bloating can feel so dramatic. Reducing sodium intake in the days leading up to your period, staying well hydrated (which counterintuitively helps your body release excess water), and maintaining regular physical activity can all blunt the effect. This type of bloating typically resolves within a day or two of your period starting.
When Bloating Signals Something Bigger
Occasional bloating after a large meal or around your period is normal. But certain patterns warrant a closer look. See a healthcare provider if your bloating gets progressively worse over time, persists for more than a week, is consistently painful, or comes alongside fever, vomiting, blood in your stool, unintentional weight loss, or signs of anemia. These can signal conditions like celiac disease, ovarian pathology, inflammatory bowel disease, or small intestinal bacterial overgrowth that need specific diagnosis and treatment rather than dietary adjustments alone.
