Periods when breathing stops completely are called apnea episodes. In obstructive sleep apnea (OSA), airflow is repeatedly blocked during the night due to a narrowing or obstruction of the upper airways.

Who Is Affected by OSA?
Obstructive sleep apnea is more common among middle-aged men, but it can affect anyone, including children. In women, the incidence increases after menopause, to the point where rates become comparable to those observed in men of the same age.

The Link Between Snoring and Sleep Apnea
Snoring can be associated with OSA, especially when it is interrupted by periods of silence, often corresponding to breathing pauses. Snoring results from a narrowing of the airways, which compresses the airflow and causes tissue vibration.
