Obstructive sleep apnea, or OSA, is a common sleeping disorder characterized by chronic and repeated interruptions in breathing during one's sleep due to the obstruction of the upper airway. Snoring, a common symptom of OSA, is the sound produced when air flows through the relaxed tissues in the throat, which causes a vibration as you breathe. Both of these may be connected, but just because one snores does not always mean they have OSA. A thorough sleep study and evaluation are necessary to determine whether or not OSA is a concern for a patient.
