Are you a snorer? Well, it could be because you have a fat tongue.
Scientists have discovered that the tongues of some people who snore are extra large.
It's already well-known that being overweight or obese increases the risk of obstructive sleep apnoea (OSA), which leads to snoring because the airway becomes blocked.
Now, U.S. researchers have found that people who snored had a higher percentage of tongue fat - especially at the base of their tongues - which made their tongues larger overall.
Increased tongue fat might prevent the tongue's muscles from positioning the tongue away from the airway, causing snoring because the airway becomes blocked, researchers said.
