How varicose veins are formed
The blood is drained from the lower limbs by means of the deep and superficial venous systems. These two systems are connected to each other by means of perforating veins, the valves of which only allow the blood to pass from the superficial system into the deep system, and not the other way around.
Varicose veins are the result of a pathological condition that’s primarily characterized by the expansion of large superficial veins and perforating veins.
There can be various causes, including genetics, foot or posture defects, gender (varicose veins are more commonly found in women), pregnancy, obesity and occupations that involve standing or sitting for several hours at a time. Graduated compression elastic stockings represent an excellent means of preventing and treating varicose veins.
