Snoring occurs when your airways are blocked while sleeping, restricting your breathing. In the case of primary snoring, the sound results from struggling to inhale. OSA occurs when snoring gets so bad that the airway is completely blocked, resulting in a lack of oxygen and the sufferer actually stops breathing - sometimes for more than 10 seconds.

Snoring can be caused by a number of different things. Being overweight, drinking alcohol, using sleeping pills and antihistamines, allergies, and a deviated septum are some common reasons that people snore. Primary snoring isn't necessarily a huge problem but it does still have negative effects on you and your family.
