The following are some statistics regarding this surprisingly common affliction.

Sleep apnea is prevalent in as many as an estimated 18 million Americans alone. This statistic denotes that approximately 1 in every 15 Americans, or 6.62% of the total American population have a case of sleep apnea.

Research conducted at the University of California’s San Diego campus studied 54 African Americans and 346 Caucasians for the presence of sleep apnea. The results showed that a full 17 percent of African American test subjects had a case of obstructive sleep apnea present, compared to 8 percent of the Caucasian subjects. This denotes a hypothesis that African Americans stand an increased risk of obstructive sleep apnea.

Two to four percent of all Americans have an undiagnosed case of sleep apnea. This accounts for approximately 1 in 50 individuals being undiagnosed.

People that are afflicted with sleep apnea face a steep increase in chances of being part of a traffic accident. Due to the sleeplessness and lack of ability to concentrate that are associated with apnea, sufferers are six times more likely to die in a car accident. As a matter of fact, the National Highway Traffic Safety Administration has stated that drowsy driving is responsible for, at the very least, 100,000 car accidents, 40,000 injuries, and 1,550 deaths per year.

More than 263,000 children per year undergo tonsillectomies. Most of these operations are performed due to the presence of sleep apnea in the children that is caused by the tonsils obstructing their air way.

A bedmate of a person with the untreated condition can lose a serious amount of sleep! Due to the breathing and gasping of the apnea sufferer, the bed mate loses up to an hour per night of sleep. This was discovered when a study was conducted that measured the effects of CPAP treatment in helping the bed mate to sleep.

People that have an untreated case of sleep apnea face a risk of stroke that is four times as likely as those who are not afflicted. Untreated sleep apnea sufferers are also three times as likely to have heart disease.

On the average night’s sleep, a sufferer of obstructive sleep apnea may experience 60 apneas per hour. This accounts for an average of 400 apneas per night!

Roughly half of all hospital patients that have a case of hypertension are also afflicted with sleep apnea. Conversely, around half of all sleep apnea sufferers face a diagnosis of hypertension.

According to the National Commission on Sleep Disorders Research, approximately 38,000 deaths occur on an annual basis that relates to cardiovascular problems that in one way or another are connected to sleep apnea. These problems include high blood pressure, hypertension, and stroke, among others. An estimated six million American residents suffer from sleep apnea that is moderate to severe and may necessitate a late night visit to the emergency room. Unfortunately, a great many people do not, as previously mentioned, even realize that they suffer from sleep apnea. This number is somewhere around 500,000 individuals.

As these statistics show, sleep apnea is not a problem to be taken lightly. The risks of mortality faced by those with untreated obstructive sleep apnea are simply not worth it when you consider all the types of sleep apnea treatment available. People with obstructive sleep apnea may not be aware that their sleep was interrupted. In fact, many people with this type of sleep apnea think they sleep well all night.

Risk factors
Anyone can develop obstructive sleep apnea. However, certain factors put you at increased risk:

  • Excess weight. More than half of those with obstructive sleep apnea are overweight. Fat deposits around your upper airway may obstruct your breathing. However, not everyone who has it is overweight and vice versa. Thin people can develop the disorder, too.
  • Neck circumference. The size of your neck may indicate whether or not you have an increased risk of obstructive sleep apnea. That’s because a thick neck may narrow the airway and may be an indication of excess weight. A neck circumference greater than 17 inches (43 centimeters) for men and 15 inches (38 centimeters) for women is associated with an increased risk of obstructive sleep apnea.
  • High blood pressure (hypertension). It is relatively common in people with hypertension.
  • A narrowed airway. You may inherit a naturally narrow throat. Or your tonsils or adenoids may become enlarged, which can block your airway.
  • Chronic nasal congestion. It occurs twice as often in those who have consistent nasal congestion at night, regardless of the cause. This may be due to narrowed airways.
  • Diabetes. It is three times more common in people who have diabetes.
  • Being male. In general, men are twice as likely to have sleep apnea.
  • Being black, Hispanic or a Pacific Islander. Among people under age 35, it is more common in blacks, Hispanics, and Pacific Islanders.
  • Being older. It occurs two to three times more often in adults older than 65.
  • Menopause. A woman’s risk appears to increase after menopause.
  • A family history of sleep apnea. If you have family members who have or had it, you may be at increased risk.
  • Use of alcohol, sedatives or tranquilizers. These substances relax the muscles in your throat.
  • Smoking. Smokers are nearly three times more likely to have it.
