What Are Varicose Veins?

According to the National Heart, Lung and Blood Institute of the United States, varicose veins are inflamed and twisted veins that can be seen under the surface of the skin. They can be purple, blue, red and green in colour and even though they normally appear on the legs, they can appear in any part of the body. Usually, people consider varicose veins as only an aesthetic issue, but the truth is, that if you leave this varicose veins untreated, the consequences could be pretty severe.

What Causes Varicose Veins?

When for various reasons the organism finds it impossible to make the blood return fluidly to the heart, it stagnates, and to make room, the vessel (the vein) is dilated.  At first, if the venous return is favored, said dilation disappears and the vein returns to its normal situation. But if this difficulty of venous return lasts too long, the vein dilates permanently. You can never forget that varicose veins are a symptom of an underlying vein disease called Chronic Venous Insufficiency, which is potentially dangerous.

It has several complications, but the most dangerous are severe bleeding when the varicose vein is ruptured and Deep Vein Thrombosis (DVT). DVT represents a danger because the blood clots that develop inside the veins may begin in a superficial one, such as a varicose vein, but later travel to deeper ones, even reaching the lungs and causing a Pulmonary Embolism, which is a potentially fatal condition.
