What is it?
Snoring is the sound produced by upper airway tissues vibrating during inspiration, when asleep. Studies report that it affects nearly half the population. Males are affected almost twice as often as are females.
Causes and contributory factors
Anything narrowing the upper airways, like enlarged tonsils/adenoids or an elongated uvula will cause partial obstruction, and these floppy tissues vibrate during inspiration. Obesity results in fat being deposited in tissues around the throat, which also causes narrowing, and is a leading cause of snoring.
