Nine self-checks and calculators, each built around a question people actually ask. They run entirely in your browser: nothing you enter is transmitted, logged or saved, and closing the page discards it. None of them diagnoses anything — what they do is tell you whether a question is worth putting to a doctor, and give you something specific to bring when you do.
What makes these different: each one handles the things generic calculators quietly get wrong — cholesterol in mmol/L as well as mg/dL, blood pressure under both the European and American systems, BMI with the lower thresholds several ethnic groups should be measured against, and the diabetic foot assessed by the international IWGDF categories rather than a points total.

How to get something useful out of them
- Answer for the side that troubles you where a tool asks about legs. Averaging a good leg with a bad one hides the finding.
- Use real figures, not remembered ones. A cholesterol value from two years ago describes two years ago.
- Write the result down with the date. The comparison that matters later is with your own earlier figure, not with a population average.
- Take it with you. "My pulse was 88 and irregular on three mornings" is a far more useful sentence in a consultation than "I think my heart beats oddly sometimes".
- Treat a reassuring result as information, not permission. Most of these tools can only see what you tell them, and several conditions here are silent until they are not.
What they cannot do
None of these tools measures anything. They apply published thresholds and decision rules to numbers and answers you supply, which means two limits follow directly. They cannot detect what you have not noticed — reduced sensation in a diabetic foot, a narrowed carotid artery, reflux in a vein — and they cannot weigh the things no questionnaire captures: family history in detail, kidney function, the appearance of your skin, what a doctor finds on examination.
They are also deliberately not treatment advice. Where a result points somewhere, the tool names the test that settles it — a colour Doppler ultrasound, an ECG, an ankle pressure measurement — rather than a treatment, because that decision belongs with the person who has examined you.
No self-check replaces emergency care. Call your local emergency number — 112 in Türkiye and across the EU, 999 in the UK, 911 in the US — for sudden weakness, facial droop or difficulty speaking; chest pain or sudden breathlessness; a leg that becomes suddenly cold, pale, numb and painful; or a leg that swells over hours with pain and warmth. If you are uncertain, treat it as an emergency rather than opening a calculator.
Where to go next
If you already know the diagnosis and want the condition explained, start from the vascular diseases overview. If you are starting from a symptom, the articles section works that way round. For a structured assessment where risk factors are present but nothing hurts yet, see vascular check-up, and for how to make first contact from abroad, the contact page sets out what to send.
Frequently Asked Questions
Is anything I enter stored or sent anywhere?
No. Every tool here runs entirely in your browser. Nothing is transmitted to a server, nothing is logged, and closing the page discards it. That is also why no result can be recovered later — write down anything you want to keep.
Can these tools diagnose a condition?
No, and none of them tries to. They apply published thresholds and decision rules to what you enter. A diagnosis needs examination and usually a test — an ultrasound, an ECG, a blood sample — and each tool names the test that would settle its particular question.
Why do some tools ask for ethnic background or sex?
Because the thresholds genuinely differ. BMI and waist cut-offs are lower for several ethnic groups because risk begins earlier, and HDL cholesterol thresholds differ between men and women. Using one set of numbers for everyone would make the result wrong for a large share of readers.
Can I use mmol/L, pounds and inches?
Yes. The cholesterol and risk tools accept mmol/L or mg/dL, and the BMI tool works in centimetres and kilograms or in feet, inches, stones and pounds. Each one warns you if a value looks as though it was entered in the other unit.
A tool gave me a worrying result — what should I do?
Read what it says about which test settles the question, write the result down with the date, and arrange to be seen. The exception is anything the tool flags as urgent or an emergency, which means the same day rather than the next appointment.
The result looks fine — can I stop worrying?
It means the questions asked did not raise a flag, which is not the same as being assessed. Several of the conditions covered here are silent in their early stages, and a self-check cannot detect what you have not noticed. If you have symptoms that persist, a normal result is not a reason to leave them.
Who wrote these and on what basis?
They were built around published guidance, named on each page — among others the Framingham risk model, ESC and ACC/AHA blood pressure classifications, NICE and WHO BMI thresholds and the IWGDF diabetic foot categories — and reviewed within cardiovascular surgery. Each page lists its sources.
Do you see international patients?
Yes. International and Gulf patients are seen in Istanbul with English- and Arabic-speaking support, and an initial remote assessment can be made from your existing reports and images before you travel.
