Unlike snoring and obstructive sleep apnea, UARS is often more prevalent among women than men.

Symptoms may include:

  • Sleep-onset insomnia
  • Headaches
  • Gastroesophageal reflux
  • Depression
  • Bruxism (grinding of teeth)
  • Rhinitis
  • Hypothyroidism
  • Asthma


People who suffer from UARS lack the typical findings of apnea, hypopnea and nighttime oxygen desaturation on polysomnography (diagnostic sleep studies). As a result, UARS is often not diagnosed by physicians. However, the arousals and sleep fragmentation related to an increased effort to breathe can be diagnosed by measurement of pressure changes in the esophagus.
