About Snoring and OSA

Nearly 1 billion adults aged 30 to 69 years are estimated to have obstructive sleep apnea (OSA) globally. There is a strong, clinically proven link between OSA and co-morbidities like diabetes, hypertension, and strokes. Mild OSA affects over 110 million people in the US and 100 million people in Europe.

Obstructive sleep apnea is marked by the recurring collapse of the upper airways during sleep. The most common symptoms are restless sleep, snoring, tiredness during the day, decreased intellectual alertness, and personality alterations. Higher risks of cardiovascular diseases and increased mortality rates have been associated with OSA.

Standard therapy of all advanced levels of sleep apnea is with a continuous positive airway pressure (CPAP) device. Many patients find this therapy invasive, and the long-term compliance of CPAP therapy is limited, so there is a clear demand for new forms of treatment.
