🌙 Validated Screening Tool

Snoring & Sleep Apnea Risk Assessment

The STOP-BANG questionnaire is the world’s most widely used, clinically validated screening tool for Obstructive Sleep Apnea (OSA). Answer 8 questions — get your risk score in 60 seconds.

Used in hospitals worldwide. STOP-BANG has a sensitivity of 93% for moderate-severe OSA. A High risk score means you should discuss a formal sleep study with your ENT or sleep physician. This tool does not replace clinical diagnosis.
Question 1 of 8 0%
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?
For example, falling asleep during driving or while at rest.
O — Observed
Has anyone observed you stop breathing during your sleep?
A bed partner or family member noticing pauses in breathing or gasping.
P — Pressure
Do you have or are you being treated for high blood pressure?
Including if you are on blood pressure medication.
B — BMI
Is your BMI greater than 35?
BMI = weight (kg) ÷ height² (m). A BMI above 35 is a significant OSA risk factor.
A — Age
Are you older than 50 years?
OSA prevalence increases significantly after age 50.
N — Neck
Is your neck circumference greater than 40 cm (16 inches)?
Measured around the Adam’s apple. A thick neck is associated with increased airway collapse during sleep.
G — Gender
Are you male?
OSA is 2–3x more common in men, though prevalence in women increases after menopause.

Understanding Your STOP-BANG Score

The STOP-BANG questionnaire was developed and validated at the University of Toronto and is now used globally as the standard pre-screening tool for Obstructive Sleep Apnea before anaesthesia, surgical procedures, and clinical sleep evaluation. Each letter represents one risk factor.

Score 0–2 | Low Risk

Low probability of OSA. Formal sleep study not routinely indicated unless significant daytime symptoms are present.

Score 3–4 | Intermediate Risk

OSA is possible. Clinical evaluation recommended. Consider home sleep test or polysomnography alongside ENT airway assessment.

Score 5–8 | High Risk

High probability of moderate-to-severe OSA. Formal sleep study and urgent ENT evaluation strongly recommended.

Score ≥3 + Male | High Risk

A score of ≥3 combined with male gender significantly increases sensitivity for clinically significant OSA.

What Happens After a High STOP-BANG Score?

A high STOP-BANG score is the beginning of the evaluation — not the diagnosis. The next step is a formal polysomnography (PSG) sleep study, which measures your AHI (Apnea-Hypopnea Index), RDI (Respiratory Disturbance Index), oxygen nadir, arousal index and sleep architecture. This is interpreted alongside a nasal endoscopy to identify the anatomical site of obstruction — nasal, palatal, tonsillar or base of tongue — and then matched to the most appropriate treatment.

At Rog Nidan ENT & Dental Clinic, Janakpuri, Dr Pranshu Mehta uses a structured OSA evaluation pathway integrating PSG interpretation, nasal endoscopy, DISE (Drug-Induced Sleep Endoscopy) where indicated, and — uniquely — coordination with airway dentistry for cases where mandibular advancement or oral appliance therapy is appropriate alongside or instead of surgery.
