Airway Resistance Syndrome (UARS) and Its Impact on Sleep
Addressing Upper Airway Resistance Syndrome (UARS) and Its Impact on Sleep: A Whole-Patient Approach
Upper Airway Resistance Syndrome (UARS) is a sleep disorder characterized by increased resistance in the upper airway during sleep, leading to disrupted sleep architecture and daytime symptoms similar to those of obstructive sleep apnea (OSA). These symptoms include excessive daytime sleepiness and fatigue. Unlike OSA, which involves clear apneas or hypopneas, UARS is marked by subtle airflow restrictions that nevertheless result in significant sleep fragmentation. Understanding UARS within a whole-patient framework is essential for effective management and improving sleep health.
The Connection Between UARS and Sleep Health
UARS disrupts sleep by causing frequent micro-arousals—brief awakenings that are often too short to be remembered but are sufficient to prevent deep, restorative sleep. These disruptions can lead to a cascade of negative health effects, including cardiovascular stress, cognitive impairment, and a decreased quality of life. Identifying and treating UARS is crucial for restoring healthy sleep patterns and mitigating its systemic impacts.
- Sleep Fragmentation: The hallmark of UARS, leading to non-restorative sleep and significant daytime impairment.
- Systemic Health Impacts: Chronic sleep disruption associated with UARS can contribute to metabolic dysregulation, mood disorders, and increased cardiovascular risk.
Distinguishing UARS from Other Sleep Disorders
UARS often presents a diagnostic challenge, as its symptoms and sleep disturbances can closely mimic those of OSA and other sleep disorders. However, the primary distinction lies in the subtlety of airway resistance and the absence of significant apneas or hypopneas in UARS. Polysomnography with esophageal pressure monitoring, though not routinely performed, can help distinguish UARS by identifying increased respiratory effort against airway resistance.
Prevalence and Clinical Importance
While the exact prevalence of UARS is difficult to quantify due to diagnostic challenges, it is recognized as a significant contributor to sleep-related complaints. Addressing UARS is clinically important not only for alleviating its immediate symptoms but also for preventing the potential progression to more severe forms of sleep-disordered breathing.
Underlying Causes
Factors contributing to the development of UARS include:
- Anatomical Variations: Narrowing of the upper airway due to structural anomalies or nasal congestion can increase airway resistance.
- Functional Abnormalities: Neuromuscular control issues affecting airway patency during sleep may also play a role.
- Lifestyle Factors: Obesity, alcohol consumption, and sedative use can exacerbate airway resistance.
Identifying Symptoms
Symptoms that may indicate UARS include:
- Excessive Daytime Sleepiness: Despite adequate sleep duration.
- Frequent Nighttime Awakenings: Often without a clear cause or recollection of awakening.
- Chronic Insomnia Symptoms: Difficulty falling or staying asleep, not explained by other causes.

Many people from infancy and into old age suffer from undiagnosed disorders that could be fixed. You don’t have to suffer, we’re here to help, we see you, we’ve got you.
Diagnostic and Treatment Pathways
Addressing UARS requires a comprehensive approach:
- Detailed Sleep Evaluation: Including polysomnography to assess for subtle signs of increased airway resistance.
- Management of Contributing Factors: Addressing nasal congestion, anatomical variations, and lifestyle factors that may exacerbate UARS.
- Positive Airway Pressure Therapy: CPAP or BiPAP therapy can be effective in reducing airway resistance and improving sleep quality.
- Oral Appliances: In some cases, dental devices that adjust the position of the jaw or tongue can help maintain an open airway.
BreatheWorks' Integrated Care Approach
At BreatheWorks, we adopt a whole-patient approach to managing UARS, recognizing the nuanced nature of this disorder and its broad impact on health. Our care strategy includes:
- Whole-Patient Assessment: Conducted by a Speech-Language Pathologist, we take a detailed case history to get a clear picture of your body’s story and assess the function of the speech and breathing mechanisms. We will observe how the muscles perform tasks like speaking, chewing, swallowing, clearing your teeth, and breathing and identify the contributing factors that may relate to your symptoms.
- Personalized Treatment Plans: Combining lifestyle modifications, therapeutic interventions, and, when necessary, medical devices to address the specific needs of each patient with UARS.
- Multidisciplinary Collaboration: Engaging a team of sleep specialists, ENT doctors, and dental professionals to provide comprehensive care.
- Education and Support: Empowering patients with knowledge about UARS and its treatment options, supporting adherence to therapy, and promoting long-term health improvements.
Conclusion
Upper Airway Resistance Syndrome represents a critical yet underrecognized sleep disorder with significant implications for health and quality of life. A whole-patient approach to diagnosis and treatment is essential for effectively managing UARS and restoring optimal sleep health. BreatheWorks is committed to providing comprehensive care for patients with UARS, leveraging a multidisciplinary team and personalized treatment strategies to address the unique challenges posed by this condition and support patients on their journey to better sleep and overall wellness.

Orofacial Myofunctional Disorders (OMD)
Orofacial Myofunctional Disorders (OMD) refer to a group of conditions characterized by abnormal patterns of muscle function and incorrect habits involving the face, mouth, and throat. These disorders can affect various aspects of oral function, including speech, swallowing, breathing, and facial development. Examples of OMD include tongue thrust (where the tongue pushes against or between the teeth during swallowing or at rest), open mouth posture (habitual mouth breathing with the mouth consistently open), and incorrect tongue resting position. OMD can contribute to dental malocclusions, speech articulation difficulties, temporomandibular joint (TMJ) dysfunction, and other orofacial issues.Orofacial Myofunctional Therapy (OMT or MYO)
Orofacial myofunctional therapy (OMT) is a specialized form of therapy designed to address and correct Orofacial Myofunctional Disorders (OMD). It focuses on retraining the muscles of the face, mouth, and throat to achieve proper resting posture, swallowing patterns, and speech articulation. OMT involves a variety of exercises, techniques, and behavioral modifications tailored to the individual’s specific needs and goals. The goals of OMT include improving orofacial muscle strength and coordination, correcting abnormal swallowing patterns, promoting nasal breathing, and enhancing overall oral function and health. OMT is typically provided by speech-language pathologists or therapists trained in orofacial myofunctional therapy techniques.Benefits of Orofacial Myofunctional Therapy (OMT)
Orofacial myofunctional therapy (OMT) can be highly beneficial for individuals with Orofacial Myofunctional Disorders (OMD). By addressing underlying muscle dysfunction and promoting proper oral habits, OMT can help improve speech clarity, correct swallowing patterns, alleviate breathing difficulties, and optimize facial development. However, the effectiveness of OMT depends on various factors, including the severity of the OMD, the individual’s commitment to therapy, and consistency in practicing exercises and techniques. OMT is often recommended as part of a comprehensive treatment plan in collaboration with other healthcare professionals, such as dentists, orthodontists, and ENT specialists, especially when addressing complex orofacial issues.We hold space in our clinicians’ schedules for new patients because we know that early intervention is the best approach. We like to see new patients in less than 2 weeks and typically schedule phase one treatments during the first visit. We can see you virtually or in person. Get started now.
