Am I at increased risk for vein problems?

Factors that increase risk of venous disease include:

Family history of venous disease including varicose veins, spider veins, and venous ulcers
Certain medical problems such as a history of blood clots, invasive procedures performed on a vein, or history of trauma to the legs increase the risk of developing venous disease.
Hormonal changes including puberty, pregnancy, and menopause increase the risk of venous disease in women. These hormonal changes stretch and weaken veins and can lead to permanent damage. Taking hormone supplements or oral contraceptives may play a role in developing vein problems as well.
Pregnancy causes varicose veins through several mechanisms. The hormonal changes can cause varicose veins even very early in the pregnancy. As the infant grows, there is increased pressure in the abdomen which makes it harder for the leg veins to empty, causing them to stretch and swell. The fluid retention and increased blood volume associated with pregnancy also strains leg veins. Although most symptoms improve after delivery, the damage caused may be permanent.
People in jobs that require them to stand or sit most of the day have an increased risk of venous disease. Furthermore, these activities may exacerbate symptoms once vein problems do develop.
