What are the Causes of Varicose Veins?

Varicose veins affect approximately a quarter of the US adult population. They are unsightly but treatable veins that occur typically in the legs. Varicose veins appear when blood is not sufficiently carried up and out of the leg and instead of flowing backward toward the feet. When a vein becomes varicose, it is non-functioning and cannot go back to ‘normal.’ If the vein is causing leg pain, swelling, discoloration, bleeding, or infection, it should be treated. It can also be treated if it is aesthetically bothersome.

Varicose veins are very different than spider veins, which are most frequently cosmetic in nature, affecting the health of your venous system. Varicose veins are generally a symptom of a deeper issue in the venous system. They are large, dilated, and bulging veins that protrude above the skin and can feel painful, heavy, and cause swelling and achiness.

Causes of varicose veins include:

  • Age

As you age, your veins stretch and their valves become weak, which allows blood to flow backward. As the blood pools, veins enlarge and appear blue, becoming varicose.

  • Pregnancy

Pregnancy increases the volume of blood in the body and decreases the flow of blood. Changes in hormones can also cause varicose veins, which can surface or worsen during pregnancy. Veins developed during pregnancy usually improve on their own after childbirth.

  • Gender and Weight

Women and those who are overweight are more likely to develop varicose veins.

  • Genetics

Vein disease is hereditary, so you are more likely to develop varicose veins if family members had them.

Advancements in technology have revolutionized the treatment of varicose veins  during the last fifteen years, and Dr. Craig Schwartz, owner and  medical director of Premier Vein & Body, has been a leader in the vein treatment industry throughout these years.  Previously, a very painful, hospital-based vein stripping procedure was the primary surgery used to physically remove diseased veins. This involved days at the hospital and weeks of recovery.  However, today’s vein specialists use minimally invasive, in–office treatment options, including laser ablation, ultrasound-guided sclerotherapy and micro-phlebectomy, to treat varicose veins and their underlying causes. Patients return home the same day and experience very minimal downtime.
