Obstructive sleep apnea is the most prevalent type of sleep apnea. People who suffer from obstructive sleep apnea stop breathing during their sleep because of a complete or partial obstruction of the airway. Many people with obstructive sleep apnea stop breathing multiple times during their sleep, often for longer than a minute at a time.
The obstruction most people have is the passage in their own mouths from the soft palate to the base of the tongue. Muscles keep this area open when a person with obstructive sleep apnea is awake. When sleeping, these muscles relax causing the soft palate and tongue to block breathing. The airway closes; the sufferer stops breathing and then wakes up in an attempt to breathe again. The sufferer falls back to sleep only to wake up many times, from five to one-hundred times per night.
The brief waking and returning to sleep only lasts a few seconds. It is enough time to keep the sufferer from achieving deep sleep and REM (rapid eye movement) sleep. Everyone needs deep and REM sleep to awake refreshed and revitalized every day.
The three main risk factors for developing obstructive sleep apnea are:
1. Age - As people get older, they lose muscle mass, which makes the airway soft and slender. When sleeping these already weak muscles relax, forming the obstruction.
2. Being Male - Men are at greater risk of developing obstructive sleep apnea.
3. Weight Gain - Weight gain is a contributing factor in obstructive sleep apnea. Excess fat makes the airway close when the muscles around it relax.
Other factors that put a person at risk of developing obstructive sleep apnea include:
Drug and alcohol abuse
Down Syndrome
Family history
Large adenoids and/or tonsils
Muscle disorders
Nasal congestion
Receding chin
Smoking
Thyroid disease
