Who is at risk for CVI?

If you have heard the letters CVI and wonder whether they could apply to you, this page starts with the simplest version of the question. Who should keep an eye out for it?
The plain answer
Anyone with risk factors for CVI should pay attention. The publisher my.clevelandclinic.org says: "If you have risk factors for CVI, you’re more likely than other people to develop the disease."
That sentence tells you what a risk factor does. It does not tell you which risk factors you carry, and that is worth sorting out with a provider who knows your history.
Where to read the background
See the Society of Interventional Radiology page on superficial venous disease and chronic venous insufficiency. MedlinePlus covers varicose veins and spider veins on its own page. Both are open to readers in the townships of Frankfort and Rich without any special setup.
One simple step
Ask your provider to go through risk factors with you, one at a time, using your own history as the guide.
A methodical diagnostician reads a risk factor as a reason to look closer, not as a verdict.
