Loud snoring is one of the most common signs of OSA. Snoring is generated by the soft tissues in the throat area vibrating as air passes over during breathing. The level of snoring is related to how constricted or narrowed the airway is. When the airway becomes completely or almost completely blocked, then obstructive sleep apnea can occur.
Increased health problems due to OSA: Diabetes, heart attack, stroke, high blood pressure, irregular heartbeat, mood changes, weight gain, tiredness.
Some common causes of OSA are: Large tongue or tonsils, aging, enlargement of the soft palate, and being overweight.
