Holding a fart means that you could "breathe out by the mouth"

But what you are about to read can make you think twice the next time you feel gas build up in your belly.

Because keeping a fart in will not just leave you feeling uncomfortable – it could make you breathe through your mouth.

According to Professor Clare Collins, an expert in nutrition and dietetics at Newcastle University.

Writing for The Conversation, she said staying in the trapped wind could cause abdominal distention, "with gas reabsorbed into the circulation and exhaled into your breath."

"Holding too long means that the intestinal gas buildup will eventually escape by an uncontrollable fart," added Professor Collins.

In the meantime, she warned that this could also lead to a disease called diverticulitis, but pointed out that the evidence was not clear.

This is where small pockets develop in the intestinal lining and become inflamed.

The strong wind is a completely natural response to the digestion of food by the body.

When food is broken down in the small intestine, the unmeasured pieces move further into the gastrointestinal tract and reach the large intestine or colon.

When the bacteria in your gut break down foods by fermentation, gases are produced.

Some are reabsorbed by the intestinal wall into the circulation and are eventually exhaled by the lungs or excreted in the form of a pet.

According to Professor Collins, it may be difficult to find motivated volunteers.

But a recent study found over a 24-hour period that the average person fartes about eight times (either eight individuals or a series of farts).

Research has shown that people crave more after a big meal and less at night.

According to Professor Collins, the gases produced in the intestines come from different sources.

"This may be due to air swallowing," she said. "Or carbon dioxide produced when the acid from the stomach mixes with bicarbonate in the small intestine.

"Or gases can be produced by bacteria that are in the large intestine."

One study found that the poorest animals were due to sulfur-containing gases.

Sixteen healthy adults were fed Pinto beans and lactulose, and the odor was badessed by two judges – yes, really, bad things!

The good news is that, in a follow-up experiment, researchers discovered that a charcoal-covered cushion "was helping to remove the smell of sulfur gases."

And, last but not least, to the latest news, Professor Collins said the model aircraft were in the line of fire.

"Pressurized cabins in planes mean you're more likely to go flat because the volume of gas increases at lower cabin pressure than on the ground," she said.

So, what should you do the next time you are overwhelmed by the urge to blow the wind in a public place?

Try to go to the bathroom, but whether you get there or not, Professor Collins said the best thing to do for your intestinal health was just to let you tear.
