Who Is At Risk for Varicose Veins?

Populations Affected

About 25 million Americans are affected by varicose veins. They are most common in people aged 30 to 70.

Risk Factors

Risk factors for developing varicose veins include:

• Genetics. Having a family member with varicose veins may increase the risk for developing them. Approximately half of the people who get varicose veins have a family history of them.
• Age. The normal wear and tear of aging may cause valves to weaken and not work as well.
• Gender. Women are two to three times more likely to develop varicose veins than men. Up to half of American women have varicose veins. Changes in hormones due to puberty, pregnancy, menopause, or taking birth control pills may increase a woman's risk of developing varicose veins.
• Pregnancy. During pregnancy, the growth of the fetus increases the pressure on the veins in the legs. Varicose veins that occur during pregnancy usually improve within 3 to 12 months following delivery.
• Overweight and obesity. Having extra weight on the body can put additional pressure on the veins.
• Prolonged standing or sitting, particularly with legs bent or crossed. When standing or sitting with legs bent or crossed, the veins have to work harder to pump the blood up to the heart.
