How To Not Be So Gassy | The Eating Pattern Most People Miss

Most people pass gas somewhere between 13 and 21 times a day. It’s a normal byproduct of digestion, but when the frequency climbs or bloating sets in, it’s easy to wonder if something is off. You’re not alone in that — gas-related discomfort is one of the more common digestive complaints people bring up with their doctors.

The good news is that gassiness often traces back to two main sources: swallowed air during eating and drinking, and the way your gut bacteria ferment certain undigested carbohydrates. Small adjustments to how you eat, what you drink, and how you move can shift things noticeably. This article covers the changes backed by major health organizations that you can try starting today.

Why Gas Builds Up In The First Place

Intestinal gas comes from two sources. The first is aerophagia — swallowing air while eating, drinking, or even talking. The second is bacterial fermentation in the colon, where undigested carbohydrates get broken down by gut microbes, producing hydrogen, methane, and sometimes carbon dioxide.

Both paths are completely normal. The volume of gas your body produces depends on what you eat, how fast you eat, and how well your digestive system handles certain foods. Some people naturally produce more gas than others, and that variation is normal too.

The key is distinguishing occasional discomfort from a pattern that affects your daily life. Occasional gassiness usually responds well to habit changes. Persistent symptoms paired with pain, cramping, or changes in bowel habits may need a medical opinion to rule out underlying conditions.

Why The Obvious Fix Often Gets Overlooked

Most people reach for an antacid or cut out beans entirely when gas becomes uncomfortable. But the interventions gastroenterologists tend to recommend first have nothing to do with medication or drastic elimination diets. They involve how you eat, not just what you eat.

• Eating too quickly: When you rush through a meal, you swallow more air along with your food. Slowing down gives your stomach time to signal fullness and reduces the air that turns into gas later.
• Using straws and chewing gum: Both habits pull extra air into your digestive tract. Each sip through a straw or chew of gum adds small pockets of air that accumulate over the day.
• Carbonated drinks and beer: The bubbles in soda, sparkling water, and beer are carbon dioxide gas released in your digestive tract. Switching to still water for a few days can help you spot the difference.
• Skipping meals or eating large portions: A very large meal in one sitting can overwhelm digestion. Smaller, more frequent meals tend to produce less gas for most people.
• Eating while stressed: Your brain and gut are connected through the gut-brain axis. Eating in a rushed or anxious state can slow digestion and contribute to bloating and gas.

These habits are easy to overlook because they are part of your daily routine. But they are also the easiest to adjust. Trying one change at a time — like ditching the straw or taking 20 minutes to eat a meal — can help you identify what makes the biggest difference for your body.

Food Choices That Can Turn Up The Gas

Certain foods are well-known gas producers because they contain carbohydrates the small intestine cannot fully digest. Beans, lentils, broccoli, cabbage, onions, and whole grains are common culprits. That does not mean you should avoid them — many are excellent sources of fiber and nutrients — but being aware of their effect can help you plan around them.

Gassiness can also stem from food intolerances. Lactose intolerance affects a large portion of the population and can cause gas, bloating, and discomfort after dairy. A food diary can help you spot patterns — if gas consistently follows certain meals, you may have found a trigger. The Ohio State Wexner Medical Center covers several common causes of gassiness that are worth reviewing for a thorough overview.

High-fiber foods tend to cause more gas when you first increase your intake, but your gut bacteria can adjust over time if you introduce them gradually rather than all at once. Drinking enough water throughout the day helps keep things moving and may reduce the bloating that comes with increased fiber.

This is not a list of foods to avoid permanently. The goal is awareness, not restriction. Many foods on the left are perfectly healthy — your body may just need time to adjust, or you may find that eating smaller portions works better for you.

Simple Daily Adjustments That May Help

Beyond food choices, a few daily routines can support how your digestive system handles gas. These adjustments carry minimal risk and are straightforward to test for a week. Many people notice a difference within a few days of changing just one habit.

1. Eat slowly and chew thoroughly. Taking at least 20 minutes per meal and chewing each bite fully reduces the air you swallow. NHS Scotland’s guidance recommends chewing with your mouth closed for the same reason.
2. Walk briefly after meals. A 10- to 15-minute walk after eating can stimulate digestion and move gas through your system more quickly. Even light movement around the block may help.
3. Try ginger with meals. Some people find ginger helps the stomach empty faster, which may reduce bloating and the gas that follows. Fresh ginger in tea or powdered ginger on food is a common approach worth testing.
4. Keep a food diary. Since triggers vary from person to person, writing down what you eat and noting when gas occurs can reveal patterns you would not catch otherwise. This is the approach the International Foundation for Functional Gastrointestinal Disorders recommends.

These adjustments target the root causes — swallowed air and fermentation patterns — rather than just masking symptoms. If one approach does not help after a week, try another. Small changes often add up over time.

When Habits Aren’t Enough

If you have adjusted your eating habits, identified trigger foods, and made lifestyle changes but still feel uncomfortably gassy, a few more options exist. Over-the-counter products like simethicone (Gas-X, Mylanta Gas Minis) are widely available and marketed for gas relief. They work by helping small gas bubbles combine into larger ones that pass more easily. That said, Mayo Clinic notes there is relatively little clinical evidence supporting their effectiveness, so individual results vary considerably.

For others, a more structured approach guided by a professional makes a bigger difference. Per the change eating habits resource from the National Institute of Diabetes and Digestive and Kidney Diseases, consulting a doctor or registered dietitian can help you tailor changes to your specific digestive patterns. That professional might suggest a low-FODMAP diet, an elimination diet, or testing for lactose intolerance depending on your symptoms.

In specific clinical scenarios — such as when bloating and fullness are the main symptoms after meals — some doctors may consider medications like metoclopramide or buspirone. These are not first-line treatments and apply to a narrow set of cases. They are prescribed only after other approaches have been tried, under medical supervision.

The Bottom Line

Gassiness is normal, and for most people it responds well to changes in how and what they eat. Eating slowly, avoiding carbonated drinks and straws, keeping a food diary, and gradually adjusting fiber intake are the strategies with the most consistent support from health organizations. Simethicone and other OTC products may offer relief for some, but the evidence is limited.

If gas is paired with persistent pain, cramping, or changes in bowel habits, a gastroenterologist can run tests for lactose intolerance, SIBO, or other underlying conditions and build a plan that fits your specific digestive patterns.
