STOP-BANG Score Calculator for Sleep Apnea Risk

Your details

Snoring that disrupts a bed partner or can be heard through a closed door counts as loud snoring.
This refers to excessive daytime sleepiness even after a full night of sleep.
Witnessed apneas are one of the strongest predictors of obstructive sleep apnea.
Hypertension (high blood pressure) is associated with increased OSA risk.
A body mass index above 35 kg/m² is a significant risk factor for OSA.
OSA risk increases substantially after age 50 due to changes in muscle tone and anatomy.
A large neck circumference (over 40 cm / ~16 in) increases the likelihood of airway obstruction during sleep.
Men have approximately two to three times higher OSA prevalence than women, partly due to differences in airway anatomy and fat distribution.

Your STOP-BANG score is 0/8 - low risk.

  • A score of 0-2 suggests a low probability of moderate-to-severe obstructive sleep apnea.
  • Even at low scores, OSA is not completely ruled out. If you have persistent symptoms like loud snoring or daytime fatigue, discuss them with a doctor.
  • The STOP-BANG questionnaire is a screening tool only. A definitive OSA diagnosis requires an overnight sleep study interpreted by a qualified clinician.

Next stepContinue to monitor your sleep quality and discuss any new or worsening symptoms with your doctor.
