What is OSA?

Obstructive Sleep Apnea is characterized as the complete or partial closure of the airway despite your body trying to breathe. When you fall asleep the muscles of the upper airway will relax and gravity will cause the tongue to fall back in the throat and occlude the airway further. 

These periods of not breathing can last anywhere from 10 seconds to over a minute in severe cases.  Individuals with severe OSA can stop breathing more than 80 times per hour.  During OSA events the body is not able to get air into your lungs in turn depriving the body of oxygen.  Your body will alert you of this lack of oxygen or increase of Carbon Dioxide by awaken you causing a gasp or snort to increase the airway and allow air to enter the lungs.  These awakenings are called arousals.  Frequent arousals during the night decrease your quality of sleep. 

Your body is meant to rest and repair itself during the night.

In different stages of sleep the body goes through different processes.  If one has OSA, the body has to actively work, repeatedly, throughout the night therefore not allowing this repair process to occur.  Many significant side affects and medical conditions can occur to the body with untreated OSA.  To list just a few; High blood pressure, heart attack, stroke, pre-diabetes and diabetes, depression and death.  Treatment of the OSA can significantly decrease or completely remove the affects of these conditions of on body.  The most preferred treatment of OSA is CPAP.
