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)
He (or she) may be the brunt of jokes at family gatherings (Uncle Joe snores so loudly he rattles the windows!), but snoring is serious business. For one, a snoring spouse often keeps the other person from a good night's sleep, which can eventually lead to separate bedrooms. Snoring can create real problems in a marriage, says Daniel P. Slaughter, MD, an otolaryngologist and snoring expert at Capital Otolaryngology in Austin, Texas. Not only is snoring a nuisance, but 75% of people who snore have obstructive sleep apnea (when breathing is disrupted during sleep for short periods), which increases the risk of developing heart disease, Slaughter says.
