FARTINING, passing wind, letting one go or having a trump, whatever you call it, it's completely natural.

But one doctor has warned that your partner's stinky farts could actually be a danger to your health.

We've all been close to tears or had streaming eyes due to the stench of something before and Dr Anthony Youn said that farts are no different.

Posting to social media, Dr Young was responding to one users who claimed they that they had 'gone blind for three minutes' after 'farting hard'.

In the Instagram video, he explained how passing wind can actually cause loss of vision.

He said: “Although this is very unlikely, if the gas you pass is extremely pungent, it could contain large amounts of hydrogen sulfide.

“Studies show that hydrogen sulfide is very effective at reducing blood pressure.

“If [a fart] reduces blood pressure to the central retinal artery, your silent but deadly toot could theoretically make you go blind.

"So be careful if you're making a lot of bubbles in your bathtub!"

The clip has garnered 570,000 views and 36,700 likes on Instagram, where viewers were stunned by the admission.

Some users said they were now 'paronoid' about farting, while others said 'you learn something new every day'.

Experts have previously also warned that you should never hold a fart in, and if you have to let one rip, you should.

Posting to TikTok, explained that on average, people fart around 14 times a day.

He joked: "The more the merrier. If someone tells you they don't fart they are lying and you should disown them immediately or they have got a bowel obstruction which is a medical emergency."

The NHS doctor explained to his 4.2 million TikTok followers that the average fart volume is enough to fill up a medium-sized balloon.

He cautioned: "If you hold in a fart too long it can be reabsorbed into your blood circulation and breathed out when you exhale."

DON'T HOLD IT IN

This could mean that your breath smells pretty bad.

Professor Clare Collins, a nutrition and dietetics expert at the University of Newcastle said holding on too long means the build up of intestinal gas will eventually escape via an uncontrollable far.

Dr Karan explained: "The first fart of your day is usually the largest. 75 per cent of farts are produced by bacteria in the large intestine.

"Digestive food that isn't broken down is chewed up by bacteria that produces microscopic farts and these accumulate before becoming your regular farts.

"25 per cent of farts is swallowed air that your don't burp and dissolved gas is from the blood making its way into your intestines.

"99 per cent of a fart is non-stinky gases such as hydrogen, carbon dioxide and methane."
