How STOP-BANG scoring works
Every positive factor adds one point.
Snoring
PendingLoud enough to disturb others
Tiredness
PendingDaytime sleepiness or fatigue
Observed apnea
PendingObserved breathing pauses, choking, or gasping
Pressure
PendingHigh blood pressure or treatment
BMI
PendingNeeds height and weight
Age
PendingNeeds age
Neck
PendingNeeds neck size
Gender
PendingNeeds sex at birth
Important note
Useful for screening, not for diagnosis.
STOP-BANG is best used to spot risk, especially when snoring and daytime sleepiness show up together. It does not confirm obstructive sleep apnea and it does not replace medical advice or a sleep study.
When this tool is helpful
- A good fit if you snore loudly, wake up tired, or someone has noticed pauses in your breathing during sleep.
- Includes the BMI, age, neck size, and sex-at-birth thresholds used in the standard STOP-BANG screening questionnaire.
- Gives you a quick score interpretation so you can decide whether it makes sense to talk with a clinician about formal sleep testing.
What to do next
Use the tool, then act on what you learn.
- Save or screenshot your score so you can discuss it during a sleep or primary-care visit.
- If you want to work on airway-support habits while you follow up clinically, Airway Trainer can help you build consistency with guided daily exercises.
STOP-BANG score interpretation and FAQs
These are the questions people usually have after they see a STOP-BANG score for the first time.
What does STOP-BANG stand for?
STOP-BANG stands for Snoring, Tiredness, Observed apnea, high blood Pressure, BMI, Age, Neck circumference, and Gender. Each item is worth one point.
What is a high STOP-BANG score?
For general-population screening, 0 to 2 points is low risk, 3 to 4 points is intermediate risk, and 5 to 8 points is high risk for obstructive sleep apnea.
Is the STOP-BANG questionnaire a diagnosis?
No. STOP-BANG is a screening tool, not a diagnosis. A higher score means it is worth talking with a clinician about formal sleep apnea testing.
What should I do if I score 3 or more?
A score of 3 or more suggests meaningful risk. Use the result as a prompt to discuss symptoms, snoring, daytime sleepiness, and testing options with a qualified healthcare professional.
How is STOP-BANG different from the Epworth Sleepiness Scale?
STOP-BANG combines anatomy and symptom questions to screen for sleep apnea risk. The Epworth Sleepiness Scale focuses on daytime sleepiness in common situations.
