What is the full form of OSA

OSA: Obstructive Sleep Apnea

OSA stands for Obstructive Sleep Apnea. It is a sleep disorder in which breathing repeatedly stops and starts during sleep. It happens during sleep when a person?s throat muscles intermittently relax and cause the tongue or fatty tissues of the throat to fall back into the airway and block the flow of air to the lungs. When the air flow is restricted and the blood flow to the brain is reduced that results in gasping, choking or snorting sounds as the person has to take a deep breath to send air beyond the obstruction. Snoring is the most common sign of this sleep disorder and it can affect anyone: men, women or children.
