Varicose veins in the lower extremities are commonly known as “floating tendons and swollen veins”, which are characterized by tortuous dilatation and stagnation of blood in the superficial veins of the lower extremities. Varicose veins in the lower extremities are caused by the degeneration and relaxation of the supporting tissues around them, combined with the swelling of the veins themselves and the inability of the valves to close, resulting in the repeated pooling of blood flow and various complications. It is hereditary and is related to the tension and elasticity of the vessel wall and the distribution of fibers. If a patient is born with a weak blood vessel wall, he is more likely to get varicose veins. Therefore, “lack of elasticity of the vessel wall” and “venous valve insufficiency” usually occur alternately. It is estimated that 20-25% of women and 10-15% of men suffer from varicose veins in the lower extremities. Varicose veins of the lower extremities mainly refer to superficial varicose veins of the lower extremities. I. What are the symptoms of varicose veins in the lower extremities? Most patients with early varicose veins have mild symptoms, mainly soreness and swelling of the lower limbs and easy fatigue when walking. After further development, that is, after the veins have been stagnant for a long time, thrombosis can be formed, and thrombophlebitis can also appear, resulting in pain, redness and swelling, and affecting activities. At the same time, varicose veins of lower limbs can also cause stagnant dermatitis, that is, after the blood is stagnant on the legs for a long time, the pressure of blood is higher, and it penetrates outside through blood vessels, forming local swelling of lower limbs, increasing intertissue fluid, itching of skin, and corresponding mossiness. If scratched, chronic ulcers will be formed, local blackening, skin thickening. Some patients with varicose veins in the lower extremities may bleed due to the protrusion of blood vessels and thinning of the skin. At an advanced stage, there will be skin pigmentation, ulcers do not heal and other situations. Second, who are more likely to suffer from this disease? Varicose veins in the lower extremities are mostly found in middle-aged and elderly people, but also in young people, mostly related to work characteristics. Generally, people who stand for a long time or sit still for a long time are prone to varicose veins of lower limbs, such as teachers, salesmen, hairdressers, surgeons, etc.; there are also some heavy laborers or athletes who exert more force on lower limbs, such as dock workers, weight lifters, etc., which can stagnate blood in veins of lower limbs to form varicose veins under excessive force; there are also some pathological states, such as habitual constipation; in addition In addition, pregnant women are also prone to varicose veins of lower limbs because of fetal compression of pelvic veins. But it should be pointed out that not the above people will definitely get varicose veins in the lower extremities, but those who have a specific physique, that is, the weak development of the vein wall are more likely to get them.
