What are varicose veins ?
Varicose disease known since the days of antiquity.On it there are mentions in the Egyptian papyri, Byzantine statute books about medicine and even in the Old Testament.To treat varicose disease were trying (often, though unsuccessfully) outstanding physicians Hippocrates of antiquity, Avicenna, Galen and Paracelsus.This disease called "the disease, knocks off his feet."The study of this disease for many years dedicated to the famous Italian physician and anatomist Marcello Malpighi.It was he who more than 300 years ago, opened the capillary circulation, and proved that blood moves from the arteries to the veins, and from there to the heart.
Varicose - exclusively human problem
Varicose veins or varicose veins (varix - node swelling, lat.) - A disease of the veins (blood vessels that carry blood to the heart), which leads to an increase in their lumen and thinning of the venous wall.Expansion

primary lesion of superficial veins of the lower extremities due to the fact that as a result of bipedal locomotion in humans 60-70% of circulating blood in the body is below the level of the heart.And if from the heart through the arteries blood runs "fast", then through the veins back to the heart, overcoming gravity, flowing "slowly and painfully."In order to ensure the normal venous drainage from the tips of the toes to the heart, there is a complicated valve device that prevents reverse movement of the blood, and the system of veins connecting the superficial and deep veins.However, in our body, there are places where the pressure of blood in the veins is increased, which leads to accelerated wear of veins in particular, the laws of physics, are most vulnerable veins of the legs.As a result, the valves begin to gradually worse work stretched vein wall, the blood stagnates and varices are formed at these locations.Of great importance are also the firmness and elasticity of the leg muscles, especially the feet and legs.
