Have you ever been in a situation where passing wind is going to be hugely embarrassing and you’ve had to hold in a fart? especially those big , deep ones..

Let’s face it – we all have.

But the gas can’t stay trapped forever, and it could even be damaging for your digestive health to prevent it from escaping like Nature wants it to.

The totally natural – but potentially humiliating – release is caused by gases created when your food and drink are digested, or when you swallow air. The phenomena would have been as unnoticed as Exhaling only that it has to come out of a channel in your body that is laced with foul surroundings and as it travels it picks up  its characteristic odour.

And if the gas isn’t given its usual way out it can be reabsorbed by the body, some of it can escape through the mouth, or after time it can escape as an uncontrollable “i must come out” fart.

Clare Collins, a professor in nutrition and dietetics at the University of Newcastle in New South Wales, Australia, writes to explain what farts are and what happens if you hold them in:


Flatus, farts and breaking wind refer to intestinal gases that enter the rectum due to the body’s usual gastrointestinal processes of digestion and metabolism and then leave via the anus.

As your body digests food in the small intestine, components that can’t be broken down move further along the gastrointestinal tract and eventually into the large intestine called the colon.

Intestinal bacteria break down some of the contents by fermentation.

This process produces gases and by products called fatty acids that are reabsorbed and used in metabolic pathways related to immunity and preventing disease development.

Gases can either be reabsorbed through the gut wall into the circulation and eventually exhaled through the lungs or excreted via the rectum, as a fart.

Trying to hold it in leads to a build up of pressure and major discomfort plus damage to internal organs.

A build up of intestinal gas can trigger abdominal distension, with some gas reabsorbed into the circulation and exhaled in your breath. Yes it can find its way out of your mouth too.

Holding on too long means the build up of intestinal gas will eventually escape via an uncontrollable fart.

The Major Constiuents of a fart is Nitrogen although some people have been seen to produce Methane and Sulphuric gas (The smelliest type)


So the next time you feel a large volume of intestinal gas getting ready to do what it does, try to move to a more convenient location.

Whether you make it there or not, the best thing for your digestive health is to just let it go.
