Causes of Vein Disease

The vascular system is comprised of the heart, arteries and veins. The heart pumps blood to organs and other body parts through arteries, and veins carry the blood back to the heart. The venous system is a low-pressure system which relies on valves to keep blood moving in the direction of the heart. In some people, veins can lose their elasticity, causing them to stretch, making the valves incompetent and this allows the blood to pool in the legs. When this blood pooling occurs, it puts more pressure on the veins, creates more valvular incompetence and eventually these veins can become enlarged or varicose; This is one of the main causes of vein disease. It leads to not only cosmetic problems but also eczema, pain, inflammation and eventually ulceration.
