Varicose Veins: Causes and Risks

Varicose veins are unfortunately something that many of us face as our bodies age, and can be unsightly if left unmanaged. So what exactly are they? Varicose, or spider veins, form when veins become swollen and twisted, making them visible underneath the skin. Typically these veins form in the legs, but other parts of your body are susceptible as well.

What causes varicose veins to form?
Your veins work to pump blood throughout the body and back to the heart. When blood is pumped from your legs specifically, the veins must work double-time against the force of gravity to send the blood all the way up to your heart. Veins are made up of one-way valves that open to let blood flow through, but if these valves are weak or damaged, blood can pool in the veins causing them to swell and create spider veins. Damaged or deformed valves can cause blood to flow backward as well, which causes the veins to bulge and swell.

Who is at risk for developing varicose veins?
According to the National Heart, Lung and Blood Institute, “many factors may raise your risk for varicose veins.” Here are some of the things that you should keep in mind and watch out for when it comes to varicose veins:

• Family History: If this condition runs in your family you’re more likely to develop varicose veins.
• Age: Since veins tend to weaken with age, the older you become, the more susceptible you are to having vein complications.
• Gender: Due to hormonal changes associated with pregnancy, menopause and the like, women are generally more likely to develop spider veins than men.
• Weight: Obesity is a huge factor in vein related conditions because being overweight can cause extra strain on your veins.
• Physical Activity: As for most health conditions, a proven record of physical activity can help prevent this condition. Sitting or standing for a long time, especially with legs crossed or bent, can cause spider veins to form more rapidly.
• Leg Trauma: Blood clots or severe damage to your veins can cause weakening and make you more at risk for blood pooling and vein swelling.
