What is Obstructive Sleep Apnea?
It is a common and serious sleep disorder that causes you to stop breathing during sleep.
An apnea (a temporary pause in breathing) is caused when the tissue in the back of the
throat collapses.
- 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, reducing the amount of air reaching your lungs.
- When this happens, you may snore loudly or make choking noises as you try to breathe. Your body and brain become 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.
Sleep apnea can make you wake up in the morning, feeling tired or un-refreshed even though
you have had a full night's sleep. During the day, you may feel
fatigued, drowsy, have difficulty concentrating or even fall asleep unintentionally.
This is because your body is waking up numerous times throughout the night, even though you
might
not be
aware of such awakenings.
