STOP-BANG Sleep Apnea Screener

The STOP-BANG questionnaire is one of the most widely validated screening tools for obstructive sleep apnea (OSA). Answer each question honestly — this screener works best when you answer based on what is actually true, not what you hope is true.

Has anyone observed you stop breathing during your sleep?

A bed partner, family member, or roommate

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

Includes treated and untreated hypertension

BMI of 35 means your weight in kg divided by height in meters squared equals 35 or more

Is your neck circumference large?

Greater than 40 cm (16 inches) for men · Greater than 37 cm (14.5 inches) for women

Important: The STOP-BANG questionnaire is a validated screening tool for obstructive sleep apnea. It is an educational estimate only and does not constitute medical advice, diagnosis, or treatment. A positive screen does not confirm OSA — formal diagnosis requires a sleep study ordered by a licensed provider. Results are not a substitute for a conversation with your healthcare provider.
