Varicose Veins, also called chronic venous insufficiency, are swollen veins due to an abnormal collection of blood due. This collection of blood can be caused by vein weakness, often inherited in the walls and valves of the leg’s superficial veins. Vein weakness causes the veins to widen and dilate, so that blood easily accumulates when a person stands or sits for long periods of time.
What is a varicose vein?
When a vein dilates, it does not fulfill its primary function. Veins are responsible for making the blood return to the heart, and that means that the flow has to go against gravity: from the foot to the heart. Veins have valves that prevent the return of blood flow to the foot and, thus, enables its rise.
However, if the vein is dilated, the valves do not fulfill their function and the flow is reversed, which causes an increase in dilation and problems such as swelling of the legs, redness or, in more advanced stages, ulcers or phlebitis (thrombosis of a varicose vein), among others. This pathology is much more frequent in women. The appearance of varicose veins is up to five more frequent in them than in men.
Venous insufficiency usually occurs in the legs, but, it can also affect the esophagus, the anal region or the testicles. If you have problems with varicosities, visit a varicose vein clinic to learn more.
There are three leading causes of varicose veins. First, and if it is primary varicose veins, there are congenitally defective valves. The valves are responsible for circulating the blood to the heart so, if they do not work correctly, blood accumulates in the vein causing swelling.
Thrombophlebitis causes the same effect. In this case, thrombi are clots, which hinder circulation. This situation can occur, for example, after prolonged periods of bed rest.
The third most probable cause is pregnancy. Fortunately, varicose veins that appear during the gestation period are secondary and tend to disappear between two and three weeks after delivery.
Evaluating the symptoms
The most common clinical manifestations are:
Heaviness in the legs
The appearance of varicose veins with visible signs showing
Pain in affected areas that may sometimes radiate up and down the legs

In more advanced stages of the disease, the patient may notice venous ulcers, ocher dermatitis (darkening of the skin), or bleeding. Affected individuals should not wait until the issue becomes complicated. Contact a vein clinic Melbourne for more details.
