How is CVI staged?

Staging sounds like a technical idea, but it is only a way of describing how far a condition has progressed. The question many first-timers ask is how chronic venous insufficiency, or CVI, gets sorted into stages.
The range of stages
my.clevelandclinic.org says the stages of venous disorders range from zero to six. It describes venous disorders as a general category for many possible issues with your veins, including CVI.
How to read a stage number
A number from zero to six is a label, and a clinician is the right person to say what yours is and what it means. You can still use the idea. When someone mentions a stage, ask what it describes and what usually happens at that point. This site covers the townships of Frankfort and Rich, and that question works the same way in any waiting room.
Pages that give more background
For background, the Society of Interventional Radiology covers superficial venous disease or chronic venous insufficiency. MedlinePlus explains varicose veins and spider veins, and my.clevelandclinic.org discusses edema, its causes and treatment. If you want to see one treatment described in detail, my.clevelandclinic.org also has a page on endovenous ablation, with procedure details and recovery.
One simple next step
At your next visit, ask which stage applies to you and what it means in everyday terms. Write the number and the explanation on one line. That line becomes a reference you can use at every later visit.
A closing observation
Numbers feel cold, yet they make a conversation easier because everyone is pointing at the same thing. Once you have your number, the plan is much simpler to talk about.
