Varicose Veins can occur or become aggravated for a variety of reasons, including hereditary traits, pregnancy, excessive straining, standing or sitting for extended periods of time, obesity, aging, and trauma.
Within the human body, veins act as transporters for the circulatory system to return blood from your extremities to your lungs and heart. Valves within the veins are structurally designed to allow blood to flow in one direction, but these valves can become faulty, allowing blood to flow backward into the vein due to gravity, this is also referred to as Chronic Venous Insufficiency (CVI).
This can cause veins to enlarge, thicken or become twisted. When this happens, varicose veins occur. Varicose veins can occur anywhere in the human body, but the superficial veins in the legs are the most commonly affected.
Spider Veins are small superficial blood vessels that appear red or blue in the skin. They commonly occur in the legs but are also found in other areas of the body including the face.
They are usually the size of a large hair and can look like a “starburst” pattern or a tree branch pattern. They can often be a sign of underlying chronic venous insufficiency (CVI).
Venous Ulcers are one of the most serious side effects of longstanding varicose veins. These typically occur in the lower leg near the ankle. Venous ulcers are caused by high venous pressure or chronic venous insufficiency.
