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)
