Sleep apnea is a serious condition that affects more than 30 million Americans who suffer from lack of restorative sleep. The majority are undiagnosed and unaware of their condition. Typical symptoms include heavy snoring, excessive daytime sleepiness or fatigue, difficulty with concentration or memory, among many others. Untreated, sleep apnea can lead to serious health consequences.
