Obstructive sleep apnea is the most common 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 region open when a person with obstructive sleep apnea is awake. Whilst the sufferer is asleep, these muscles relax causing the soft palate and tongue to obstruct breathing. The airway shuts; the sufferer stops breathing and then wakes up trying to breathe again. The sufferer falls back to sleep only to wake up on multiple occasions, from five to one-hundred times per night.
The brief waking up and going back to sleep only lasts a few seconds. It is long enough to prevent the person from achieving deep sleep and REM (rapid eye movement) sleep. All people need deep and REM sleep to wake up refreshed and revitalized each morning.
Three of the main risk factors for developing obstructive sleep apnea are:
1. Age - As people grow older, they lose muscle mass, which makes the airway soft and thin. When sleeping these already weak muscles relax, forming the obstruction.
2. Being Male - Men are at greater risk of getting obstructive sleep apnea.
3. Weight Gain - Weight gain is a contributing factor in obstructive sleep apnea. Excess fat causes the airway to close in when the muscles around it relax.
Other factors that put a person at risk of getting 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
