What Is Chronic Venous Insufficiency?
Veins carry blood back to your heart. They rely on valves — or flaps — to open and close to allow the blood to move forward.
Chronic venous insufficiency is a vein condition.
It occurs when the valves become weak or damaged, allowing blood to pool in your legs instead of moving back your heart. This can put pressure on your vein walls and cause a range of symptoms.
Chronic venous insufficiency causes and risk factors
Weak or damaged valves cause chronic venous insufficiency.
Some risk factors that can lead to weak or damaged valves include:
- Personal or family history of varicose veins
- Being age 50 or older
- Being female
- Obesity
- Pregnancy
- Deep vein thrombosis (DVT), or a blood clot in a vein deep below your skin
- Sitting or standing for long periods
- Being physically inactive
- Smoking
