Varicose veins are generally the result of abnormal blood flow. The veins in the body bring blood back from the tissues to the heart and lungs to get oxygen. Blood can flow the wrong way in diseased veins.
This is particularly true in the legs, where returning blood must fight gravity. The result is enlarged, painful, and unsightly veins. These. Enlarged, visible, or uncomfortable leg veins called varicose veins are a common medical and cosmetic concern, affecting about one-third of the population. Why do they happen.
Varicose veins, and their milder counterpart spider veins, are enlarged, twisted veins. They can affect both men and women and most commonly involve the legs (due to gravity). In normal veins, flow is directed toward the heart by one-way valves in the veins.
“Varicose veins form in the layer of fat between the muscle and skin,” she explains. As we age or experience hormone changes, the valves in our leg veins weaken, and may allow blood to leak. You can see varicose veins that develop close to the skin; varicose veins can develop deep within your body tissues, so you cannot see them with your naked eye. Doctors consider varicose veins to be diseased veins, as the veins do a poor job of moving blood up out of your lower legs. Varicose veins are caused by increased pressure in the veins.
Varicose veins happen in the veins near the surface of the skin (superficial). The blood moves towards the heart by one-way valves in the veins. When the valves become weakened or damaged, blood can collect in the veins and cause the pressure inside these leg veins to build.
Although rarely serious, varicose veins can be distressing and feel very uncomfortable. And as one in three people develop the blue or purple bulging veins in their legs, it’s worth knowing what causes them and how to treat them. Here are six things you need to know about varicose veins.
1. Varicose veins are just one of the visible signs of underlying venous insufficiency. Venous insufficiency, also known as vein disease, is a result of damaged vein valves that cause blood to pool within the legs. This poor circulationoften leads to symptoms such as: Restlessness, especially at night. In simple terms, varicose veins are veins that become enlarged, twisted, and pooled with blood (which gives them their distinct bluish, purple-colored appearance).
Varicose veins—also known as spider veins in more mild cases—are a common condition that affects over three million people nationwide each year. Marked by knotty, blue veins that are easily visible at the surface of the skin, they are most commonly found on the legs and ankles.
