What Causes Varicose Veins to Form?

Have you ever wondered what causes those unsightly varicose veins on your legs?    It’s estimated that about 20% of all adults will develop varicose veins at some point in their lives, and most of them that do have a family history of the condition.   So what causes varicose veins to form?

What are varicose veins?

Varicose veins are swollen, bulging blood vessels that lie in deep layers of tissue beneath the skin.   They are typically purplish or blue in color.  Varicose veins can occur anywhere in the body, but are most often seen on the legs.   

Varicose veins are generally harmless, but can sometimes become achy, painful, and irritated.  Depending on the severity of the symptoms your doctor may recommend treatment to close the varicose veins.

What causes varicose veins to form?

Varicose veins form as a result of damage to the one-way valve within the vein.  Veins contain one-way valves that open and close to keep the blood flowing in one direction – towards the heart.  However, if the valves become damaged for any reason and blood begins to flow backward or pool in the veins, they eventually swell and become misshapen.  These swollen, twisted veins are known as varicose veins.

While varicose veins are more common in older people, they can affect younger adults as well.  Obesity, pregnancy, a family history of the condition, and sitting or standing for long periods, are some of the factors that contribute to the formation of varicose veins.   In addition, varicose veins are more prevalent in women than in men.
