UARS

UPPER AIRWAY RESISTANCE SYNDROME

Upper airway resistance syndrome (UARS) is a condition in which patients snore, wake frequently during the night, and have excessive daytime sleepiness. However, UARS patients do not have the breathing abnormalities that characterize sleep apnea and they do not show a reduction in blood oxygen levels. This syndrome affects the area from the front of the nose to back of the upper throat.  It occurs when the passage of air through this area is restricted.  This restriction can be caused from swelling and inflammation, or deformity of the airway. 

Unlike apnea, UARS is more likely to occur in women than in men.

Treatments are similar to those of sleep apnea. Treatment options include medical regimens, oral appliances and in extreme situations surgical intervention.

It is not known if UARS has any serious health complications.
