Varicose Veins
Overview
A varicose vein is an enlarged vein, the contents of which are stagnant or refluxing. The function of your veins is to channel blood back to the heart. The larger veins have valves which direct the flow of blood. When any of these valves fail, blood can accumulate under pressure, engorging and distorting the veins in your leg. Varicose veins appear as either bulging and rope-like, or small and thread-like. They can result in aching, tired and swollen legs; create a burning, throbbing, or itching sensation; and cause muscle cramps and a general restlessness in your legs. Varicose veins are a vascular disorder requiring treatment for medical reasons.
Causes
One clear factor is heredity. Most patients who suffer from varicose veins have a family history of the condition. Another factor is hormonal changes that specifically affect women. Pregnancy or birth control pills further increase your chances of developing vein disorders. Other contributing factors include prolonged standing, being overweight and/or trauma to the leg.
