Ever been in a situation where passing wind is going to be hugely embarrassing and you’ve had to hold in a fart? Let’s face it – we all have.
Trying to hold it in leads to a build up of pressure and major discomfort. A build up of intestinal gas can trigger abdominal distension, with some gas reabsorbed into the circulation and exhaled in your breath. Holding on too long means the build up of intestinal gas will eventually escape via an uncontrollable fart.
The research is not clear on whether the rise in pressure in your rectum increases your chance of developing a condition called diverticulitis, where small pouches develop in the gut lining and become inflamed – or whether it doesn’t matter at all.
What is flatus?
As your body digests food in the small intestine, components that can’t be broken down move further along the gastrointestinal track 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.
