UARS: The Overlooked Sleep Disorder That Mimics Apnea but Demands Attention
Upper airway resistance syndrome (UARS) is a sleep-related breathing disorder that shares similarities with obstructive sleep apnea (OSAS) but remains less severe. First identified in 1993, it affects individuals who experience disrupted sleep, daytime fatigue, and breathing difficulties—yet lack the clear apnea episodes seen in OSAS. Without proper treatment, the condition can worsen over time, leading to broader health complications.
UARS develops due to anatomical differences in the upper airway, such as narrowing between the uvula, soft palate, or epiglottis. Obesity and certain demographic factors can also contribute to increased airway resistance. As a result, sufferers often struggle with snoring, morning headaches, unexplained nighttime awakenings, and persistent exhaustion during the day. Over time, untreated UARS may raise blood pressure, trigger cardiovascular problems, and even evolve into full-blown OSAS.
Diagnosing the condition begins with a visit to a sleep specialist, otolaryngologist (ENT), or pulmonologist. Patients describe their symptoms before undergoing a sleep study, known as polysomnography (PSG), to confirm the issue. University clinics, like the Department of Otolaryngology at Medical University Graz, frequently handle such assessments.
Treatment varies but commonly includes CPAP therapy, the most researched and widely used option. Other approaches involve surgery, orthodontic adjustments, or custom oral appliances. For those also dealing with anxiety, depression, or insomnia, combining talk therapy—such as cognitive behavioural therapy (CBT)—with medical interventions can improve outcomes.
Left unmanaged, UARS can deepen fatigue, worsen mental health, and heighten risks for metabolic and heart-related conditions. Early diagnosis and tailored treatment—whether through CPAP, dental devices, or therapy—help restore sleep quality and reduce long-term health consequences.
