obstructive sleep apnea (osa)
Sleep apnea is a common and serious sleeping disorder that happens when your regular breathing is interrupted during sleep. Snoring is common among patients with sleep apnea but not all snorers have sleep apnea.
There are two main types of sleep apnea:
- Obstructive sleep apnea (OSA). The more common form, it is the result of blocked airflow during sleep, usually when the soft tissue at the back of the throat collapses while you sleep. Health factors, such as obesity may contribute.
- Central sleep apnea. Results from a problem with how the brain signals the breathing muscles. The airway is not blocked, instead the brain fails to signal the muscles to breath. This type of sleep apnea can occur with conditions such as heart failure, brain tumors, brain infections, and stroke.
Sleep apnea can affect any one at any age, although men are more likely to develop the disorder. The risk is also greater for those:
- over 40
- with large tonsils, large tongue or small jaw
- with a family history of sleep apnea
- with a nasal obstruction due to a deviated septum, allergies or sinus problems
If left untreated, sleep apnea can result in a number of health problems including:
- high blood pressure
- heart failure, irregular heartbeat and heart attack
- worsening of ADHD
Sleep apnea can be treated. There are several options:
- Adjusting sleeping habits. This may mean simply not sleeping on your back
- Continuous positive air pressure (CPAP). This is a device which improves breathing while you sleep. The device supplies air through the nasal passages and the air pressure keeps the airway open while sleeping.
- Oral appliances. Certain oral devices can shift and support the jaw to prevent the airway from collapsing. Research shows that oral appliances can successfully prevent sleep apnea in some mild to moderate cases.
- Surgery. According to the American Academy of Dental Sleep Medicine, upper airway surgery may be recommended when other treatment options are unsuccessful in eliminating the symptoms of sleep apnea. Depending on the location and nature of the airway obstruction, the procedure may be minimally invasive or more complex. It may be necessary to remove the tonsils or other parts of the soft palate or throat.
If you think you have sleep apnea, make sure to speak with your physician or dentist for more information and possible evaluation.
