Travelers who deboard airplanes may feel relieved to be out of a cramped cabin and away from the bad in - flight of stairs moving picture . But sometimes there ’s still a bit of physical uncomfortableness as some passengers report feel bloated or having to pass gasolene after a flight . Here ’s the understanding why .
Post - flight flatulence , which is sometimes playfullydescribedas HAFE , or High - Altitude Flatus Expulsion , is actuate by uncomplicated physics . When we ’re on board airplanes , the melody pressuredecreasesas elevation growth . Because we have air in the bowel — and more of it depend on the gases acquire by food we wipe out or bare we swallow — the lower pressure level think those gas expand , creating a need to secrete them via the reliable method of farting .
perish from broken to eminent altitudes apace may also prevent carbon dioxide from dissolving in the bloodstream and causing it to propagate in the intestine , leading to increase gastrointestinal pressure . ( This was verified in a 2013studyin which Australian scientists drove content up a spate resort to an altitude of about 5900 foot . Farts nearly doubled compare to flatulence experienced prior to the ascent and were present even 11 hour following the trip . Another example of scientific discipline working for everyone . )
As for why gas seems to sense a chip more uncomfortable after getting off a flight , you may thank strangle cabins . Being seated for too long can trap air in the intestine . By the time you ’re off the plane , you might feel a mo overstuffed .
If post - flight flatulence is an offspring , it ’s best to avoid gaseous state - causing foods like broccoli and beans as well as carbonated beverages . Some physicians evenrecommendavoiding foods that settle under the FODMAP , or Fermentable Oligo- , Di , Mono - sugar And Polyols , list . That intend milk , yogurt , certain veg , and stilted sweeteners .
The most important backsheesh ? Get up and walk . In addition to keeping gas from getting trapped , you ’ll avoid complications from sit too long , like mystifying vein thrombosis , or DVT , a rake clot thatformsin the leg and can lead to pulmonic embolisms .
