Upper Airway Resistance Syndrome (UARS)

Do you often wake up feeling tired even after a full night’s sleep? Do you frequently experience daytime fatigue or a lack of energy? Do you struggle with falling or staying asleep, or find yourself waking up with headaches? Are you dealing with cognitive issues such as memory problems or difficulty concentrating? Have you noticed mood changes like increased irritability, anxiety, or feelings of depression? If you’ve had a sleep study that didn’t reveal significant apnea but you still experience poor sleep quality, you might have Upper Airway Resistance Syndrome (UARS).

UARS is a sleep disorder that, like obstructive sleep apnea (OSA), involves disrupted breathing during sleep, but it’s characterized by increased resistance in the upper airway rather than complete or partial blockages. This resistance leads to frequent arousals and poor sleep quality without causing significant drops in blood oxygen levels, making it harder to detect and often missed in sleep studies.

Prevalence of UARS

UARS is increasingly recognized as a significant sleep disorder, though it is often underdiagnosed due to its subtle presentation. Unlike OSA, which is more common in overweight individuals, UARS frequently affects those with a normal body mass index (BMI), particularly women. While the exact prevalence is difficult to determine, UARS is believed to impact a substantial portion of the population, especially those who do not fit the typical profile for OSA.

Symptoms of UARS

The symptoms of UARS can be subtle and often overlap with other sleep disorders, making it challenging to diagnose. Common symptoms include:

  1. Daytime Fatigue: Persistent tiredness and lack of energy, even after a full night’s sleep.
  2. Frequent Arousals: Repeated awakenings throughout the night, which may not be remembered in the morning.
  3. Non-Restorative Sleep: Feeling unrefreshed upon waking.
  4. Insomnia: Difficulty falling or staying asleep.
  5. Morning Headaches: Common in UARS sufferers, often related to sleep disturbances.
  6. Snoring: Typically lighter than in OSA, but still a sign of airway resistance.
  7. Cognitive Difficulties: Problems with memory, focus, and mental clarity.
  8. Mood Changes: Increased irritability, anxiety, or depressive symptoms.

How Do I Know if I Have UARS?

If you suspect you have UARS based on the symptoms listed above, the best way to confirm the diagnosis is through a sleep study. Our office offers take-home sleep studies, which provide a convenient way to monitor your breathing patterns, sleep stages, and other vital parameters in the comfort of your own home. The data from this study will be reviewed by a qualified sleep physician to determine if UARS is present and guide the appropriate treatment plan.

Dental Treatment Options for UARS

As a dental office specializing in the treatment of sleep-related breathing disorders, we offer effective, patient-friendly solutions to manage UARS:

  1. Mandibular Advancement Devices (MADs): These oral appliances reposition the lower jaw slightly forward, enlarging the airway and reducing resistance. MADs are particularly effective in treating UARS because they directly address the structural issues contributing to airway resistance, offering a comfortable and less invasive alternative to Continuous Positive Airway Pressure (CPAP) therapy.
  2. NightLase® Therapy: NightLase is a non-invasive laser treatment that tightens the tissues of the soft palate and surrounding areas. By tightening these tissues, NightLase can reduce airway resistance, decrease snoring, and improve sleep quality. This treatment is painless, requires no surgery, and has shown promising results in improving symptoms of UARS.
  3. Myofunctional Therapy: This therapy involves exercises designed to strengthen the muscles of the mouth, tongue, and throat. By improving muscle tone, myofunctional therapy can help reduce airway resistance, complementing other treatments like MADs and NightLase.
  4. Nasal Breathing Optimization: Techniques to improve nasal airflow, such as the use of nasal dilators or addressing structural issues through surgery, can also enhance the effectiveness of MADs and NightLase therapy.
  5. Lifestyle Modifications: Weight management, avoiding alcohol, and steering clear of sedatives can all help reduce airway resistance and improve overall treatment outcomes.

If you suspect you may have UARS, we encourage you to get tested. Contact our office to learn more about our take-home sleep study and explore how our treatment options can help you achieve better sleep and improved well-being.
