Sleep apnea is a potentially serious sleep disorder in which breathing repeatedly stops and starts. You may have sleep apnea if you snore loudly, and you feel tired even after a full night’s sleep.
The main types of sleep apnea are:
- Obstructive sleep apnea, the more common form that occurs when throat muscles relax.
- Central sleep apnea, which occurs when your brain doesn’t send proper signals to the muscles that control breathing.
- Complex sleep apnea syndrome, also known as treatment-emergent central sleep apnea, occurs when someone has both obstructive sleep apnea and central sleep apnea.
