Varicose veins are the most common disease of the venous system, formed mainly due to congenital weakness of the vessel wall membrane or maintaining the same posture for a long time with few changes, blood accumulates in the lower extremities and over time destroys the venous valves and produces excessive venous pressure, a symptom of blood vessels protruding from the skin surface. Varicose veins occur in the lower extremities, and others can also be found in the scrotal spermatic cord, abdominal vena cava, and esophageal veins of the stomach. Long-term standing workers are the people who are prone to varicose veins in the lower extremities. Varicose veins are the veins in the legs of the patients that are flexed and dilated, which seriously affects the health of the legs and can cause serious harm if not treated in time. What are the hazards of untreated varicose veins: Bleeding: The skin of the area through which varicose veins pass is very fragile due to lack of nutrition. If you are not careful, it is easy to rupture the varicose vein, which can cause hemorrhage. Because bleeding is often not accompanied by other symptoms such as pain, it is often unnoticed by the patient and can lead to serious consequences if it occurs at night while sleeping. Edema: Due to the reflux of the veins, the patient presents with morning and evening edema of the affected limbs. Venous thrombosis: In some patients, a thrombus can form in the superficial varicose vein, which is characterized by localized redness, swelling, pain, and hard lump formation, which affects walking. If left untreated, the thrombus may spread upward or through the traffic veins to the deep veins, resulting in deep vein thrombosis with the risk of life-threatening pulmonary embolism. Ulcers: The most common consequence of varicose veins is the occurrence of ulcers due to the nutritional changes in the skin caused by varicose veins, which can be long-lasting and locally foul-smelling and pus-filled, and can have a serious impact on daily life.
