It has been estimated that roughly 30–50% of the US population snore and almost one-third suffer from sleep apnoea. However, only 5% have been diagnosed and treated. Snoring and sleep apnoea result from obstructed airways. This can be an outcome of many different factors, such as anatomic deviations, tumours, polyps, allergies, large adenoids and tonsils, a large uvula or a long soft palate. Heavy snoring is sometimes called “heroic” snoring may affect bed partners, even causing marital conflict.
