Obstructive sleep apnea occurs when the muscles in the back of your throat
When the muscles relax, your airway narrows or closes as you breathe in, and
you can't get an adequate breath in. This may lower the level of oxygen in your
blood. Your brain senses this inability to breathe and briefly rouses you from
sleep so you can reopen your airway. This awakening is usually so brief that you
don't remember it.
You may make a snorting, choking or gasping sound. This pattern can repeat
itself from 5 to 100 times each hour, all night long. More than five apneas per
hour is abnormal. More than 30-40 per hour is considered severe sleep
apnea.These disruptions impair your ability to reach the desired deep, restful
phases of sleep, and you'll probably feel sleepy during your waking hours.
Consult a medical professional if you experience any of the above symptoms.
