What is the primary cause of obstructive sleep apnea?

Question

Quizplus · Accepted Answer

The primary cause of obstructive sleep apnea is a small or unstable pharyngeal airway, which can be caused by various factors such as obesity, enlarged tonsils, or anatomical abnormalities. Deviated septum and unstable larynx may contribute to sleep disturbances, but they are not the primary cause of obstructive sleep apnea. While a large tongue can be a contributing factor, it is not the primary cause either.
