How to Avoid Bloating and Stomach Pain During a Flight

If you've ever stepped off a plane feeling bloated, uncomfortable, and wondering what happened to your stomach, you're not alone. Many travelers assume the problem starts with the food served during the flight, but digestive health experts say the real culprit may be what you ate in the days leading up to takeoff.

According to Dr. Megan Rossi, a leading British digestive health specialist, the foods we consume in the 24 to 48 hours before flying can significantly affect how we feel in the air. Combined with changes in cabin pressure, certain foods can increase gas production and lead to bloating, stomach discomfort, and pressure during a flight.

Why Flying Can Cause Bloating

As an airplane climbs, the air pressure inside the cabin decreases. According to the laws of physics, gases naturally expand when pressure drops.

That means the gas already present in your digestive system expands as well, which can lead to bloating, abdominal pressure, stomach pain, and increased gas.

The good news? A few simple dietary changes before your trip may help reduce the discomfort.

1. Avoid High FODMAP Foods Before Flying

Dr. Rossi recommends limiting foods high in FODMAPs during the 24 to 48 hours before a flight.

FODMAPs are certain carbohydrates that can be difficult for the body to digest. When they reach the intestines, they may ferment and produce additional gas.

Some common high FODMAP foods include:

• Garlic
• Onions
• Cauliflower
• Apples

These foods can already contribute to gas production on the ground. Once you're in the air, that gas may expand and lead to even greater discomfort.

2. Skip Carbonated Drinks and Chewing Gum

Many travelers reach for a soda or chew gum during a flight without realizing they may be making bloating worse.

Carbonated Drinks

Soft drinks contain gas bubbles that add extra air to the digestive system, increasing the likelihood of bloating and discomfort.

Chewing Gum

Chewing gum may seem harmless, but it often causes people to swallow additional air without noticing. That trapped air can build up in the stomach and contribute to bloating during the flight.

3. Stay Away From Heavy, Fatty Meals

Airport fast food can be tempting, especially before a long journey. However, fatty and fried foods are often harder to digest.

Foods such as burgers, fries, and other greasy meals can slow stomach emptying and digestion. When food remains in the digestive system longer, it may increase fermentation and gas production.

Combined with hours of sitting and reduced cabin pressure, this can leave travelers feeling especially uncomfortable.

What Should You Do Instead?

Fortunately, there are a few simple habits that can help keep your digestive system working smoothly during a flight.

Drink Plenty of Water

Staying hydrated is one of the easiest ways to support healthy digestion.

Dehydration can contribute to constipation and bloating, making digestive discomfort even worse. Drinking enough water before and during your flight can help keep things moving properly.

Get Up and Move Around

Long periods of sitting can slow digestion and make trapped gas more noticeable.

Whenever possible, stand up, stretch, and take a short walk down the aisle. Even gentle movement can help stimulate the digestive system and reduce feelings of bloating and pressure.

A More Comfortable Flight Starts Before You Board

What you eat before a flight can have a bigger impact than many people realize.

Avoiding gas producing foods, skipping carbonated drinks, limiting heavy meals, staying hydrated, and moving regularly during the flight may help reduce bloating and make your journey far more comfortable.

Sometimes the secret to feeling better in the air starts long before you reach the airport.
