There is no such thing as the fastest way to treat blood viscosity. It is recommended to take dietary control, proper exercise and medication as a comprehensive conditioning treatment. 1. Dietary control: If the total cholesterol level and LDL level are increased, dietary attention should be paid to reduce the intake of total cholesterol, such as eating less animal offal, chicken skin, fat meat and other foods. 2. Appropriate exercise: It is recommended that patients with thickened blood should choose some soothing aerobic exercises, such as walking, jogging, tai chi, hiking, swimming, etc., in order to promote blood circulation and accelerate lipid metabolism in the body. 3. Medication: If the total cholesterol level is still high, consider medication under doctor’s guidance, mainly statin drugs, such as atorvastatin, simvastatin, etc.; if the triglyceride level is high, mainly choose beta drugs, such as fenofibrate, benzapentolate, etc.. It is important to pay attention to blood lipid levels and carry out lipid regulating treatment to lower total cholesterol levels and LDL cholesterol and raise HDL cholesterol, as well as to improve lifestyle, reduce cardiovascular risk factors and improve quality of life.
