Edema in the legs is a common condition that can have various underlying causes. Chronic venous insufficiency (CVI) is one of the conditions that can cause edema in the legs.
CVI occurs when the veins in the legs do not efficiently return blood to the heart, leading to a buildup of blood and fluids in the legs. In this article, we will discuss the causes, symptoms, diagnosis, and treatment options for CVI.

CVI can be caused by various factors that affect the proper functioning of the venous system. The most common causes of CVI are:.
- Varicose veins
- Deep vein thrombosis (DVT)
- Obesity
- Pregnancy
- Smoking
- Sedentary lifestyle
Symptoms of Chronic Venous Insufficiency
CVI can cause several symptoms that can affect the legs and other parts of the body. The most common symptoms of CVI are:.
- Swelling or edema in the legs, ankles, and feet
- Pain in the legs, especially after long periods of standing or sitting
