Your veins are vessels that carry blood from your body’s tissues to your heart and lungs to pick up more oxygen and get re-circulated through your body. The muscles in your legs aid in this process, contracting to help pump the blood upward.
Each vein has tiny valves inside it to keep the blood flowing in the right direction; this one-way traffic keeps blood from flowing backward. However, a malfunction can occur in one or more of these valves, a common condition we call venous insufficiency. Venous insufficiency is what causes varicose veins and spider veins and affects 30 – 40 million Americans.
Learn the causes, symptoms, and treatments of venous insufficiency directly from Dr. Sanjiv Lakhanpal, President & CEO of Center for Vein Restoration.
Varicose veins are swollen, twisted, blue veins that are close to the surface of the skin. Because valves in these veins are damaged, they hold more blood at higher pressure than normal.
