Sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts. If you snore loudly and feel tired even after a full night’s sleep, you might have sleep apnea. Sleep apnea causes episodes of decreased oxygen supply to the brain and other parts of the body.
The three types of sleep apnea are:
- Obstructive sleep apnea: This is the most common type of sleep apnea, in which the airway has become narrowed, blocked, or floppy.
- Central sleep apnea: There is no blockage of the airway, but the brain doesn’t signal the respiratory muscles to breathe.
- Mixed sleep apnea: This is a combination of obstructive and central sleep apnea.
