Obstructive sleep apnea is a common and serious disorder in which breathing repeatedly stops for 10 seconds or more during sleep. The disorder results in decreased oxygen in the blood and can briefly awaken sleepers throughout the night. Sleep apnea has many different possible causes. In adults, the most common cause of obstructive sleep apnea is excess weight and obesity, which is associated with soft tissue of the mouth and throat. During sleep, when throat and tongue muscles are more relaxed, this soft tissue can cause the airway to become blocked.
Once asleep again, the muscles relax and the airway becomes blocked, cutting off the airway again. This cycle can occur hundreds of times per night. Obstructive Sleep Apnea is the most common form of sleep apnea. It ranges in severity from mild to moderate, to severe. Other forms of sleep apnea include Central and Mixed Sleep Apnea.
