If the total cholesterol test result is 6.5mmol/L, it belongs to hypercholesterolemia and needs to be treated with lipid-lowering drugs. Elevated total cholesterol in the blood will increase the incidence of cardiovascular and cerebrovascular diseases; high total cholesterol will increase the viscosity of the blood, which is easy to be deposited on the blood vessel wall to form plaque, thus affecting the blood supply of the blood vessels; therefore, when the total cholesterol is 6.5mmol/L, it is necessary to take medication to control the cholesterol under the guidance of the doctor. At present, the commonly used clinical cholesterol-lowering drugs are statin lipid-regulating drugs, such as atorvastatin, lovastatin, etc.; for patients with obvious abnormalities in liver function, decompensated cirrhosis should be used with caution, and prohibited in acute hepatic failure; and there are also drugs such as Probucol. Specific medication should follow the doctor’s instructions, not self-administration. Patients with significantly elevated total cholesterol values should be controlled under the guidance of a doctor with medication, exercise, reasonable diet and other measures to avoid affecting personal health.
