Stop Bang Calculator
The STOP-BANG Calculator is a clinically inspired screening tool used to assess the risk of obstructive sleep apnea (OSA). Sleep apnea is a serious condition where breathing repeatedly stops and starts during sleep, often without the person realizing it.
Many people suffer from poor sleep quality, daytime fatigue, or loud snoring without knowing the underlying cause. The STOP-BANG questionnaire helps identify individuals who may be at risk and need further medical evaluation.
This calculator is widely used in healthcare screening, pre-surgery assessments, and general health risk evaluation.
What is Sleep Apnea?
Sleep apnea is a sleep disorder where breathing repeatedly stops during sleep due to airway blockage or brain signal issues.
Common symptoms include:
- Loud snoring
- Daytime sleepiness
- Gasping during sleep
- Morning headaches
- Poor concentration
If untreated, sleep apnea can lead to serious health problems such as:
- High blood pressure
- Heart disease
- Stroke
- Diabetes
What is STOP-BANG?
STOP-BANG is an acronym representing eight risk factors used to screen for sleep apnea.
STOP Components:
- S: Snoring
- T: Tiredness during daytime
- O: Observed breathing stops
- P: High blood pressure
BANG Components:
- B: BMI over 35
- A: Age over 50
- N: Neck circumference large
- G: Gender (male risk higher)
Each positive answer increases the risk score.
Purpose of STOP-BANG Calculator
The calculator is designed to:
- Screen risk of sleep apnea
- Identify high-risk individuals early
- Support medical diagnosis decisions
- Encourage sleep health awareness
- Assist doctors in pre-assessment
It is not a diagnosis tool but a risk indicator.
How the STOP-BANG Calculator Works
The tool assigns 1 point for each “yes” answer in the STOP-BANG questionnaire.
Total score ranges from:
- 0 to 8
Risk levels:
- 0–2: Low risk
- 3–4: Moderate risk
- 5–8: High risk
Higher scores indicate higher probability of sleep apnea.
