Sleep apnea is one of the most common sleep disorders afflicting approximately 20 million adults in the U.S. with an estimated 80% of cases going undiagnosed. Many people may be unaware that a sleep disorder is the underlying cause of their health problems, and others may be aware of their sleep disorder but uninformed of the severe consequences of untreated sleep apnea. Sleep apnea is characterized by frequent breaks or pauses in breathing during sleep. There are 3 forms of sleep apnea: Central sleep apnea (CSA) in which the pauses are due to the brain failing to signal the respiratory system to breathe; obstructive sleep apnea (OSA) in which breathing is interrupted by a physical blockage in the upper airways, often caused by soft tissues of the throat and tongue collapsing into the airway; and complex/mixed sleep apnea which is a combination of central sleep apnea and obstructive sleep apnea.
