Too Many Toots? What Excessive Farting Says About Your Health.

Doctors share their thoughts on what’s normal when it comes to gas and what needs to be checked out.

Whether it happens on your postprandial fart walk, right in the middle of yoga class or while you’re sleeping, everyone — even the poshest among us — farts.

According to Dr. Satish Rao, professor of Medicine at Augusta University’s Medical College of Georgia, the average person farts seven to 24 times a day.

“It’s a normal physiological phenomenon,” he said, explaining flatulence as the byproduct of fermentation in the colon.

That fermentation creates gas, which is a mixture of nitrogen, oxygen, carbon dioxide, methane, hydrogen and more. One surprisingly smelly fact is that more than 99% of farts are odorless, but a foul smell comes from trace sulfur compounds. Unfortunately, our noses are extremely good at detecting sulfur, even in microscopic amounts.

Once that gas is formed, Rao said there are only two options for it to escape. “Some gas will move from the lining of the colon to the bloodstream, then get exhaled by the breath,” he said. “But the other pathway out is the fart. The gas will find its way out eventually, and if you produce a lot of gas too quickly, it won’t be absorbed, but will automatically push its way out through the anus.”
