More about Sleep Apnea?
Typically, normal breathing then starts again, sometimes with a loud snort or choking sound. The term "sleep-disordered breathing" (SDB) includes a spectrum of respiratory disorders ranging in severity from snoring to OSA.
Sleep apnea usually is a chronic (ongoing) condition that disrupts your sleep 3 or more nights each week. You often move out of deep sleep and into light sleep when your breathing pauses or becomes shallow.
This results in poor sleep quality that makes you tired during the day. Sleep apnea is one of the leading causes of excessive daytime sleepiness.

Prevalence
In a community-based study, men were found to be 2 times more likely than women to have OSA. However, men are 8 times more likely to be treated for OSA than women. This suggests that the symptoms of OSA in women are often attributed to other conditions, such as chronic fatigue syndrome, depression, and fibromyalgia.
Untreated OSA can severely affect quality of life, health and mortality. Clinical research shows that it is linked strongly to a range of serious, even life-threatening, chronic diseases such as stroke, heart failure, hypertension, diabetes, obesity and coronary heart disease.
