Snoring is a common problem, caused by a blockage of the nasal passages during sleep. Snoring can be a sign of a serious problem called sleep apnea, where you stop breathing for 10 seconds or more during sleep. There are two types of doctors who treat snoring problems: sleep medicine doctors and otolaryngologists (ear, nose and throat doctors). (AndreyPopov/iStock/Getty Images)
While snoring can be harmless, it can also be the sign of a more serious medical condition known as Obstructive Sleep Apnea (OSA).When Obstructive Sleep Apnea occurs, the tongue and soft palate collapse onto the back of the throat and completely block the airway, which restricts the flow of oxygen.
