WHAT IS OBSTRUCTIVE SLEEP APNEA?
Sleep-Related Breathing Disorder
During sleep, as the muscles relax, a complete or partial blocking of the upper airway can occur.
Obstructive sleep apnea (OSA) is a sleep disorder characterized by repeated obstruction to the airway during sleep. OSA occurs when the muscles supporting the soft tissues in your throat, such as your tongue and soft palate, relax. This causes your airway to narrow or even close, momentarily cutting off your breathing. This leads to interrupted and irregular sleep, restlessness and loud snoring. Left untreated, OSA can cause serious health problems such as high blood pressure, heart disease, stroke, diabetes, abnormal heart rhythm, and pulmonary hypertension.
