Do you feel exhausted during the day even though you’re technically “sleeping” through the night? Do you snore lightly, wake often, or struggle with concentration and energy?
If so, you could be dealing with a lesser-known but impactful condition called Upper Airway Resistance Syndrome (UARS). It’s often missed or misdiagnosed, especially in patients who don’t fit the typical profile for obstructive sleep apnea (OSA). But the effects of UARS are very real—and fortunately, so are the solutions.
WHAT IS UARS?
Upper Airway Resistance Syndrome is a sleep-related breathing disorder that occurs when the airway becomes partially blocked during sleep, increasing the effort it takes to breathe. Unlike obstructive sleep apnea, UARS doesn’t usually cause complete airway collapse or long pauses in breathing. However, it still leads to frequent micro-arousals—brief awakenings that disrupt sleep quality.
These interruptions aren’t always noticeable to you, but your brain is forced to keep “checking in” on your breathing throughout the night. Over time, this leads to poor-quality, fragmented sleep and the frustrating symptoms that come with it.
COMMON SYMPTOMS OF UARS
Many patients with UARS don’t snore loudly or appear to stop breathing—so it’s easy for this condition to go undetected. Instead, UARS is often associated with:
- Feeling tired despite “enough” hours of sleep
- Light snoring or noisy breathing
- Frequent nighttime awakenings
- Trouble falling or staying asleep
- Morning headaches
- Daytime fatigue or brain fog
- Anxiety or mood swings
- Sensitivity to sounds, light, or stress
- TMJ symptoms or teeth grinding (bruxism)
UARS can affect both adults and children, and it’s especially common in people with smaller jaws, narrow airways, or nasal congestion.
HOW IS UARS DIFFERENT FROM SLEEP APNEA?
While both UARS and OSA disrupt sleep, there are some key differences:
| UARS | OSA | |
| Airway Collapse | Partial (increased resistance) | Complete (brief stoppage of airflow) |
| Oxygen Drops | Typically mild or none | Often significant |
| Snoring | Light or absent | Loud and frequent |
| Sleep Disruption | Frequent micro-arousals | Full awakenings often due to gasping |
| Health Risks | Cognitive fatigue, stress sensitivity | Heart issues, high blood pressure |
Even though UARS may seem “milder” than OSA, its impact on energy, mood, and focus can be just as serious.
TREATMENT OPTIONS FOR UARS
The good news is that UARS is very treatable—and the right plan can help you get deeper, more restorative sleep. At our practice, we take a personalized approach to care that targets the root cause of your breathing difficulties.
Here are the most effective treatment options for UARS:
1. Oral Appliance Therapy
Oral appliances are custom-made devices worn during sleep that gently adjust the jaw to keep the airway more open. For UARS patients, this can reduce resistance and improve airflow without the need for a CPAP machine.
Benefits include:
- Comfortable and discreet
- Easier to use than CPAP
- Great for people with jaw-related airway narrowing
2. Orthopedic Expansion
If the root cause of UARS is a narrow upper jaw or nasal passages, we may recommend maxillary expansion. This treatment widens the upper arch and improves space for both the tongue and airflow.
Options include:
- MARPE (Miniscrew-Assisted Rapid Palatal Expansion): Ideal for older teens and adults
- RPE (Rapid Palatal Expansion): Often used in growing children
- DOME (Distraction Osteogenesis Maxillary Expansion): A surgical option for complex cases
These techniques can reduce nasal resistance, improve tongue posture, and make a long-term difference in breathing comfort.
3. Myofunctional Therapy
This exercise-based therapy strengthens the muscles involved in breathing, speaking, and swallowing. For UARS patients, it’s especially helpful in:
- Improving nasal breathing
- Correcting tongue posture
- Reducing nighttime airway resistance
Myofunctional therapy is often used in combination with oral appliances or expansion techniques for the best results.
4. Behavioral and Lifestyle Support
For some patients, addressing sleep position, stress levels, or nighttime nasal congestion can improve symptoms. We’ll also look at habits like mouth breathing or tongue posture that could be contributing to airway resistance.
WHY PROPER DIAGNOSIS MATTERS
Because UARS is harder to detect than obstructive sleep apnea, many patients go untreated or are misdiagnosed with insomnia, anxiety, or chronic fatigue. If you’ve been told your sleep study is “normal” but you still feel exhausted, UARS may be the missing piece.
A proper evaluation—including a physical airway exam and possibly a sleep study—can help us determine what’s going on and how to help.
