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)
Be sure to tell your physician of any past or present drug and medication use. If you can, ask your partner, roommate or family member if they have ever heard you snore. A sleep medicine physician will recommend a home sleep apnea test, or in some cases an in-lab sleep study. A board-certified sleep physician is specially trained to diagnose sleep apnea.
