Obstructive sleep apnea (OSA) is a sleep disorder characterized by repetitive pauses in breathing during sleep, caused by a partial or complete obstruction of the upper airway. The obstruction often occurs when the soft tissues at the back of the throat collapse and block the airway, leading to decreased airflow or even temporary cessation of breathing. These breathing disruptions can last for a few seconds to minutes and may happen multiple times throughout the night, disrupting the normal sleep pattern and preventing the person from reaching restorative deep sleep stages.
