Sleep apnea (AP-ne-ah) is a common disorder in which you have one or more pauses in breathing or shallow breaths while you sleep.
Breathing pauses can last from a few seconds to minutes. They may occur 30 times or more an hour.
Typically, normal breathing then starts again, sometimes with a loud snort or choking sound.
Sleep apnea usually is a chronic (ongoing) condition that disrupts your sleep.
When your breathing pauses or becomes shallow, you’ll often move out of deep sleep and into light sleep.
As a result, the quality of your sleep is poor, which makes you tired during the day.
Sleep apnea is the leading cause of excessive daytime sleepiness and is also linked to high blood pressure and diabetes.
