Does flying make Crohn's worse?
Does flying make Crohn's worse? Flying causes an increased risk of developing deep vein thrombosis (DVT) or blood clots - particularly in flights over eight hours long. Having Crohn's disease or ulcerative colitis can put you at a three times greater risk of developing DVT than the general population, with flares creating an even further risk1.
Can flying affect your intestines?
Your digestive system is hard at work on your flight so it's important to understand the stress that bloating after flying has on your overall health. Because you have excess gas taking up room inside of your intestines, bloating can be uncomfortable and take the form of stomach pain and issues passing gas.
Does flying mess with your digestive system?
The air pressure makes you bloated and gassy. That lower pressure causes the gases in your gut to expand, resulting in bloating and gassiness, Dr. Movassaghi says. That can make your stomach feel uncomfortably full or crampy, or make you fart more.
