STOP-BANG Questionnaire: Screen Your Risk of Sleep Apnea

The STOP-BANG questionnaire is a validated 8-item screening tool used by clinicians worldwide to identify people at risk of obstructive sleep apnea (OSA). Answer each question honestly — your result is calculated instantly and never leaves your browser.

S — Snoring

Do you snore loudly (louder than talking or loud enough to be heard through a closed door)?

T — Tiredness

Do you often feel tired, fatigued, or sleepy during the daytime?

O — Observed apnea

Has anyone observed you stop breathing during your sleep?

P — High blood pressure

Do you have, or are you being treated for, high blood pressure?

B — BMI over 35 kg/m²

Is your body mass index over 35?

A — Age over 50

Are you older than 50 years?

N — Neck circumference over 40 cm

Is your neck larger than 40 cm (approx. 16 inches)?

G — Male gender

Are you male?

How the STOP-BANG score is interpreted

0–2: Low risk of moderate-to-severe OSA
3–4: Intermediate risk — worth discussing with a GP
5–8: High risk — a formal sleep study is strongly recommended

Important limitations

STOP-BANG is a screening tool, not a diagnosis. Only a sleep study (polysomnography or a home sleep test) can confirm obstructive sleep apnea. If your score is intermediate or high — or if your partner has witnessed you stop breathing — please book a GP appointment. See our guide on what to expect during a sleep study.
