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)
âMost people who snore donât have obstructive sleep apnea, but most people who have apnea snore,â says Robert L. Owens, MD, of the Sleep Disorders Research Program at Brigham and Womenâs Hospital in Boston. If you have chronic snoring that is loud enough to wake a bed partner, talk to your doctor. Like snoring, the most definitive sign of sleep apnea -- waking up to breathe -- is often witnessed by a bed partner. People with sleep apnea frequently wake up for a few seconds to gasp for air.
