Everyday stop bang problems come down to one relationship between sex, your height, your weight, neck female, neck male, sleep — alarming signs, pressure, snoring, constant tiredness and select all that apply to you…. This calculator turns those numbers into stop-bang score and bmi, with the working shown so you can check the result rather than simply trust it.
What Is the STOP BANG Calculator?
The stop bang calculator gives you an estimate of stop-bang score and bmi based on sex, your height, your weight, neck female, neck male, sleep — alarming signs, pressure, snoring, constant tiredness and select all that apply to you....
It is a quick reference figure rather than a diagnosis, and it is most useful for tracking how a number moves over time rather than for interpreting a single reading.
How the STOP BANG Estimate Is Worked Out
The calculation follows published reference relationships, so it is a reasonable approximation when the inputs are accurate. It assumes an average adult and does not account for individual variation.
If you are comparing two people, or the same person over a period of weeks, keep the method and the inputs identical. A change in the method can easily look like a change in the person.
What This Calculator Does Not Do
It does not diagnose anything, and it does not replace advice from a clinician. If a figure comes out at an extreme, or if it differs sharply from what you expect, that is a reason to speak to a professional rather than to adjust the inputs.
Nothing you type here is stored or sent anywhere. The whole calculation happens in your browser.
A Worked Example
Working through an example, with sex set to 0, your height set to 10, your weight set to 5, the calculator returns bmi of 0.05, and stop-bang score of 111,101,010. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out stop-bang score?
Enter sex, your height, your weight, neck female, neck male, sleep — alarming signs, pressure, snoring, constant tiredness and select all that apply to you.... The calculator then works through the relationship and reports stop-bang score and bmi.
What does the stop bang actually calculate?
It takes sex, your height, your weight, neck female, neck male, sleep — alarming signs, pressure, snoring, constant tiredness and select all that apply to you... and converts them into stop-bang score and bmi using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter sex?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
Why does a small change in one value move the answer so much?
That happens when an output depends on a ratio, because dividing by a small number magnifies any change in it. Check the units first, then check whether the value you entered is in the range the relationship was designed for.
