The word “apnea” means “without breath”. There are three types of apnea: obstructive, central, and mixed. The most common type of “apnea” is “Obstructive Sleep Apnea (OSA)”. OSA is caused by the blockage of your airway. If you have OSA, you stop breathing repeatedly during your sleep and for periods of times that may last for a minute or longer.
OBSTRUCTIVE SLEEP APNEA
Obstructive sleep apnea is a common and serious sleep disorder that causes you to stop breathing during sleep. The airway repeatedly becomes blocked, limiting the amount of air that reaches your lungs. When this happens, you may snore loudly or make choking noises as you try to breathe. Your brain and body becomes oxygen deprived and you may wake up. This may happen a few times a night, or in more severe cases, several hundred times a night.
In many cases, an apnea, or temporary pause in breathing, is caused by the tissue in the back of the throat collapsing. The muscles of the upper airway relax when you fall asleep. If you sleep on your back, gravity can cause the tongue to fall back. This narrows the airway, which reduces the amount of air that can reach your lungs. The narrowed airway causes snoring by making the tissue in back of the throat vibrate as you breathe.
Sleep apnea can make you wake up in the morning feeling tired or unrefreshed even though you have had a full night of sleep. During the day, you may feel fatigued, have difficulty concentrating or you may even unintentionally fall asleep. This is because your body is waking up numerous times throughout the night, even though you might not be conscious of each awakening.
The lack of oxygen your body receives can have negative long-term consequences for your health. This includes:
- High blood pressure
- Heart disease
- Pre-diabetes and diabetes
Snoring is the often loud or harsh sound that can occur as you sleep. You snore when the flow of air as you breathe makes the tissues in the back of your throat vibrate. The sound most often occurs as you breathe in air, and can come through the nose, mouth or a combination of the two. It can occur during any stage of sleep.
About half of people snore at some point in their lives. Snoring is more common in men, though many women snore. It appears to run in families and becomes more common as you get older. About 40 percent of adult men and 24 percent of adult women are habitual snorers. Men become less likely to snore after the age of 70.
