Upper Airway Resistance Syndrome (UARS)

UARS is caused by a flow limitation or blockage of air in the nasal passages during sleep. It is important to note that individuals with UARS can present with identical symptoms to individuals with OSA (Obstructive Sleep Apnea).

Common Features

Cold hands



Chronic fatigue

Low blood pressure

Lightheadedness when standing up rapidly

Also Associated:

Sleep onset insomnia

Runny Nose


TMJ disease




Raynaud's phenomenon or Raynoud's Disease

*People that suffer with UARS can be young thin individuals that have chronic fatigue, low blood pressure, lightheadedness, and  dizziness upon standing 

This diagnosis can be missed with a standard Sleep test

UARS patients frequently progress into OSA later in life. For women, this can occur after menopause when progesterone levels drop.  This is thought to participate in the protective upper airway reflexes prior to menopause.  

Stress Increases and Organ Function Decreases

There is an association with increased stress levels and decreased function of the gastrointestinal system and reproductive organs as well as other body systems.
