Obstructive Sleep Apnea

Obstructive sleep apnea occurs when the upper airway repeatedly narrows or closes during sleep, disrupting sleep quality and breathing.

Common symptoms

  • Loud snoring, choking, or gasping during sleep
  • Witnessed pauses in breathing
  • Morning headaches, dry mouth, or unrefreshing sleep
  • Daytime sleepiness, fatigue, poor concentration, or irritability

Evaluation basics

Testing may include a home sleep apnea test or an in-lab polysomnography, depending on symptoms, medical history, and clinical context.

Self-assessment

Do you have risk factors for obstructive sleep apnea?

The STOP-Bang questionnaire is a screening tool that estimates risk for obstructive sleep apnea. It does not diagnose sleep apnea. A sleep study is needed to diagnose OSA.

S — Snoring: Do you snore loudly, louder than talking or loud enough to be heard through closed doors?

T — Tired: Do you often feel tired, fatigued, or sleepy during the daytime?

O — Observed: Has anyone observed you stop breathing, choke, or gasp during sleep?

P — Pressure: Do you have, or are you being treated for, high blood pressure?

B — BMI: Is your body mass index greater than 35 kg/m²?

A — Age: Are you older than 50?

N — Neck: Is your neck circumference greater than 16 inches / 40 cm?

G — Gender: Were you assigned male at birth?
