Do you wake up during the night sometimes with the sensation of choking or grasping for breath? Do you wake up with headaches and have trouble staying awake during the day? If you answered yes to the questions above, chances are you may already be under a threat of a serious, potentially life-threatening sleeping disorder called sleep apnea.

Sleep apnea is a breathing disorder characterized by brief interruptions of breathing during sleep. It comes from the Greek word, apnea, meaning "want of breathe."

According to the National Institute of Health, sleep apnea affects more than 18 million Americans. It occurs in all age groups and both sexes but is more common to men over the age of forty. Sleep apnea seems to run in some families, suggesting a possible genetic basis.

Early recognition and treatment of sleep apnea is important because it may be associated with memory problems, weight gain, impotency, irregular heartbeat, high blood pressure, heart attack, and stroke.

Fortunately, sleep apnea can be diagnosed and treated. Several treatment options exist, such as behavioral therapy, physical or mechanical therapy and surgery. For many sleep apnea patients, their spouses are the first ones to suspect that something is wrong, usually from their heavy snoring and apparent struggle to breathe.
