BMI and waist-risk check: what your number leaves out
Someone handed you a number — and it still didn't tell you what to do about it. Maybe it was a health camp printout, an app, or a comment at a checkup that stayed with you longer than it should have. A number on its own can make you feel judged without making anything clearer. What actually helps is context: what has changed, what has been measured, what someone qualified has already flagged. Take two private minutes to get that context straight — then get measured properly, with something useful to say.

What is a BMI and waist-risk check?
A BMI and waist-risk check is a short, structured set of questions about the context around body measurement — how your weight has changed, how clothes fit around your middle, how recently anyone measured you, and what a professional has already raised. This check does not ask for your height or weight and does not calculate a BMI figure. A measured BMI and waist reading, taken by a health professional and read alongside your history, is the real check — and neither measurement defines your health or establishes eligibility for any medicine by itself.
Frequently asked questions
Does this check calculate my BMI?
No. It does not ask for your height or weight and does not produce a BMI figure. It organizes the context around body measurement — what has changed, what has been measured, what a professional has already mentioned — so that a proper measurement becomes a useful conversation rather than just a number. A measured BMI and waist reading taken by a health professional is the real check.
Does BMI tell me whether I am healthy?
No. BMI is a screening measure calculated from height and weight. It does not distinguish muscle from fat, does not show where fat is carried, and does not account for your history, activity, family background or test results. Waist measurement adds useful context about where weight sits. Neither measurement defines your health on its own, and both are best read by a professional alongside everything else about you.
Can a BMI or waist result confirm that I am eligible for weight-loss medicine?
No. No measurement, and no online tool, establishes eligibility for any prescription medicine. Only an appropriately qualified prescriber can decide whether a medicine is suitable, after assessing you individually. If you want to prepare for that conversation, the GLP-1 Consultation Readiness Check helps you gather what a clinician will ask for — it also cannot confirm eligibility.
Why does this check ask about family history?
Because a clinician usually will. A family history of diabetes, heart disease or high blood pressure is one commonly discussed factor among many — it is context for a conversation, not a prediction and not fate. This check cannot tell you what your family history means for you; that needs a professional who can see the whole picture.
Are my answers private?
Yes. Your answers produce a result for you. Sensitive answers are never sold, sent to advertisers or used to build a marketing profile. Saving a result to track it over time is optional and happens in the Nily app.
What should I do with a "several factors worth discussing" result?
Treat it as a prompt to get measured properly, not as a verdict. It does not mean anything is wrong, and it has not diagnosed or ruled out anything. The useful next step is a professional who can measure you, read the numbers alongside your history and tell you what — if anything — is worth acting on.
Weight dropping without you trying to lose it, breathlessness at rest, or chest discomfort or pressure on mild effort can have several causes and deserve prompt assessment by a qualified professional — please don't wait for a quiz result. If you have chest pain, severe breathlessness, fainting or another rapidly worsening emergency, call 112 now or go to the nearest emergency department. Nily is not a crisis or emergency service.
This check does not calculate your BMI, does not measure your waist and cannot diagnose or rule out any condition. Neither BMI nor waist measurement defines your health, and neither one establishes eligibility for any medicine — only an appropriately qualified prescriber can decide that, after assessing you individually.
