This Is Why You're Always Bloated During Travel — Here's How to Fix It Before Your Next Trip

"I usually tell people to bring their own snacks," Dr. Nazareth said. Instead of munching on the cookies the flight attendant hands out, Dr. Nazareth recommends snacking on whole foods like fruit.

Another way to prevent bloating and constipation is to stay hydrated. Dr. Nazareth recommends travelling with a reusable water bottle (the Larq bottle is self-cleaning) to prevent becoming dehydrated and to keep your digestive system happy.

Whether you're travelling to a secluded island, for work, or to visit your family, Dr. Nazareth said to stay active once you reach your destination. You don't have to do an intense workout, but you should move around and walk as much as possible to regulate your digestion and avoid constipation.

She also recommends going outside in the sunlight so you can reset your digestion's circadian rhythm. "The sooner you get back to normal daylight, and your body recognises the sunlight is now out at a different time, the sooner things will get back to normal," she said.
