Varicose veins are lengthening, widening, and the winding of superficial veins that can occur in the legs, start from thighs, calves, to ankles.

Varicose veins are abnormal forms of superficial veins or blood vessels visible on the surface.

Veins are basically used to transport remnant metabolism blood of all body tissues and return to the heart. 
Throughout the human body, including the legs, there are blood vessels (veins) where are the places of blood flow from the organ to the heart. Basically, there are two types of veins, i.e. inside and outside. Both of these blood vessels support each other in performing their duties. However, if there is interference on a point in the blood vessels, it will offend the overall blood vessels. Blood circulation that is not smooth is due to obstruction around the calves and legs while holding the weight of the body.

Regarding the cause of varicose veins, it is because the blood circulation that is not smooth as a result of:
a. Decreased the elasticity of veins which causes the vessels weakened and unable to drain blood to heart as it should. The blood flow is from the legs to the heart against gravity. Therefore, blood vessels must be strong, so is the surrounding muscle dynamics.
b. The damage of the vein valves. In fact, the valve duty is resisting the blood flow to the heart to keep it out again. The damaged valve will create unstoppable blood in the blood vessels, and cause impaired blood flow. When vein elasticity loses, it will stretch to become more elongated and widened, then meander to clot and form of varicose veins.
