Varicose veins is a common condition observed in practice whereby patients present with dilated, tortuous and elongated veins, especially on the legs. However, any vein in the body if gets twisted, stretched out or looses elasticity, could be labeled as varicose.
The veins have certain valve like mechanism which allows the blood to move upwards toward the heart. The valves have leaflets. When the leaflets loose their elasticity, the valves loose their capacity to push blood upwards; hence there is a back pressure which leads to further elongation of the veins. The veins also have reduced elasticity. As a result, the veins get ‘tortuous’ or twisted; as well as hardened. The veins, thus, become visible as zigzag vascular tubes, especially on legs.
Varicose veins affect especially the depending parts of the body that is lower limbs, which gets even worse when one tends to stand longer. People in the business of standing for long, such as sales people, policemen, plastic surgeon (tend to stand for hours during surgery), etc. are risk of developing varicose veins
