What is Obstructive Sleep Apnea (OSA)?

Obstructive sleep apnea (OSA) is a potentially serious sleep disorder that causes breathing to repeatedly stop and start during sleep.

There are several types of sleep apnea, but the most common is obstructive sleep apnea. This type of apnea occurs when your throat muscles intermittently relax and block your airway during sleep. A noticeable sign of obstructive sleep apnea is snoring.
