What are the causes of varicose veins?

Veins send blood back to your heart for re-oxygenation. While traveling through the veins back to the heart, blood passes through small valves that prevent the blood from flowing backwards. Over time, these valves become less effective and cause a backflow of blood. This is the cause of varicose veins.

If I develop varicose veins, how can I treat them?

There are several treatments for varicose veins. Many are outpatient surgery options with varying degrees of invasiveness. These treatments include:

Laser surgery: Lasers are used to close of veins. Typically used for smaller veins.
Vein stripping: A large part of the vein is removed. Circulation is maintained by deep veins
Catheter procedure: A heated catheter burns away the small valves in the veins.
Ambulatory Phlebectomy: The skin is punctured in various spots to remove the vein.
Sclerotherapy: A solution is injected into the veins that closes them off. The body redirects the blood through alternate veins.
Endoscopic vein surgery: For serious cases only. A video camera is used to navigate the closing of veins.

Always consult with a physician before undergoing any type of treatment.
