Vein Facts:

Varicose veins are a sign that there is high pressure in the veins. This is called venous insufficiency or venous hypertension.

Role Heredity Plays in Varicose Veins

Written by Dallas Vein Specialists on June 14, 2014

shutterstock_78673816A normal and healthy leg vein contains one-way valves that prevent blood from flowing backwards. If these venous valves or the walls of the veins weaken or malfunction, blood may start to leak and flow away from the central circulation and toward the pull of gravity. This causes varicose veins, which are swollen and enlarged. One out of every two Americans over the age of 50 develops varicose veins. Most common in the lower portion of the leg or lower thigh, varicose veins can be raised or bulge above the skin’s surface, and appear rope-like.

Several factors may increase your risk of developing varicose veins at some point of your life. One of the primary risk factors for varicose veins is heredity.

If a close family member has varicose veins, you have a greater chance of developing them because of your bodies’ structural similarities. If one of your parents has varicose veins, you have a 49 percent chance of developing them. If both of your parents have varicose veins, your risk rises to 90 percent.

Heredity is not the only risk factor. Other factors include gender (females are more prone to varicose veins), age, being overweight and pregnancy.

With a family history of varicose veins, there is very little you can do to prevent them from developing. Exercise is good for your circulation, especially the venous circulation. If you work a sedentary desk job, take frequent short walks or while sitting, flex your ankle and foot, which causes the calf muscles to contract and thereby increases the emptying of the leg veins.  Wearing compression hose further aids the emptying of the leg veins and often relieves the discomfort of distended varicose veins.

However, if you do develop varicose veins, we encourage you to seek treatment with the team at Dallas Vein Specialists.


We offer a variety of varicose vein treatments in Dallas, including minimally invasive options. Every patient has different needs that require a unique solution. Some of our treatments incorporate the use of laser energy to damage the vein so it closes and eventually disappears. We strive to make treatment as safe, quick and unobtrusive as possible, for your comfort and convenience.
