Upper airway resistance syndrome (UARS)

Upper airway resistance syndrome (UARS) affects younger, more physically fit individuals who don’t correspond to the typical profile of someone who suffers from sleep apnea, but have its characteristic daytime sleepiness and poor energy levels. When these patients undergo diagnostic testing for apnea in a laboratory sleep study, they don’t have overt apneas (brief periods in which airflow is completely obstructed), but wake frequently. While snoring is often associated with the UARS condition, at least 10 percent of UARS patients do not snore. UARS patients have fewer, milder apneas, but suffer increased heart-rate variability because their sympathetic nervous system is activated over and over again.

UARS can sometimes be misdiagnosed as fibromyalgia, particularly in female patients. At Reardon Dental Health, we partner with regional sleep doctors to diagnose and find the most appropriate treatment for UARS, as well as snoring, obstructive sleep apnea, and other sleep disorders.
