Obstructive sleep apnea (OSA) is one of the most common, but potentially serious forms of Sleep-disordered breathing (SDB). People of all ages, shapes and sizes can suffer from OSA without ever knowing it. In fact, an estimated 90% of the people who have OSA have never been diagnosed.
The repeated awakenings associated with OSA make normal restorative sleep impossible. People with obstructive sleep apnea often experience severe daytime drowsiness, fatigue, depression or irritability.
