There is no effective drug treatment for varicose veins, but only non-surgical symptomatic treatment (wearing medical compression stockings or elastic bandages, etc.) and surgical treatment. Varicose veins are caused by a combination of genetic and acquired factors. Genetic factors such as weak vein walls and defective valves, and acquired factors such as prolonged standing, strenuous physical activity, chronic coughing, and chronic constipation combine to cause excessive pressure on the valves, resulting in the development of varicose veins. For varicose veins that are already present, medication is often ineffective. Generally, non-surgical symptomatic treatment is used. Wearing medical compression stockings or elastic bandages, avoiding activities that aggravate varicose veins (e.g., prolonged standing, sedentary, high-intensity physical activities, etc.), and intermittent elevation of the limbs can also alleviate the symptoms. Surgery should be performed if conservative treatment is not effective. Pharmacological treatment of varicose veins is only aimed at treating the symptoms of varicose veins accordingly, but it cannot cure or prevent the progress of the disease. Once varicose veins are diagnosed, the long-term progression of varicose veins is more rapid than the initial stage, so they should be treated as early as possible to avoid aggravation of the condition.
