The chances of getting varicose veins can be reduced but not eliminated. Sitting for long periods with legs unelevated or crossed, being overweight, taking birth-control pills, and drinking alcohol can contribute to the condition. Heredity is a factor: Half of people with varicose veins have a family history of the problem, according to the National Heart, Lung, and Blood Institute.

Pregnancy, which adds pressure to veins, also raises the odds. “Vessel fragility changes with age and hormones,” says Rondi K. Walker, a plastic surgeon in DC. “Even with treatment, varicose veins do come back.”

The most common area for varicose veins is the legs, and any activity that keeps the blood moving is helpful for prevention. “Get plenty of exercise and always take the stairs,” Dr. Walker says. If you have a problem already, wear compression stockings
