The Stink in Your Fart

Apparently, the stink in farts control blood pressure.

A smelly rotten-egg gas in farts controls blood pressure in mice, a new study finds.

The unpleasant aroma of the gas, called hydrogen sulfide (H2S), can be a little too familiar, as it is expelled by bacteria living in the human colon and eventually makes its way, well, out.

The new research found that cells lining mice’s blood vessels naturally make the gas and this action can help keep the rodents’ blood pressure low by relaxing the blood vessels to prevent hypertension (high blood pressure). This gas is “no doubt” produced in cells lining human blood vessels too, the researchers said.

The article goes on to explain that researchers subjected mice to conditions comparable to hypertension in humans. The mice which were missing a gene responsible for the production of were unable to relax their blood vessels as much as the mice which did have the gene.

This doesn’t mean that if you fart often that you’ll have low blood pressure since hydrogen sulfide only accounts for the stink of your ass gas, not the whole shebang of gases and pressure, but it does mean that science editors are getting better at writing attention-grabbing headlines.
