Cholesterol 6.9mmol/L needs to be controlled by medication if lifestyle improvements are not effective or if risk factors such as high blood pressure are present. The normal reference value for cholesterol is less than 5.2mmol/L, and levels above 6.2mmol/L are considered elevated. Since maintaining a high cholesterol level for a long period of time will increase the risk of atherosclerosis-induced cardiovascular diseases such as coronary heart disease and cerebral infarction, active intervention is required. Lifestyle interventions, such as avoiding oily and salty foods in the diet, quitting smoking and drinking, and maintaining appropriate physical activity, are usually taken first. If the above measures are ineffective, or if the patient has risk factors such as hypertension, diabetes, coronary heart disease, etc., it is often necessary to rely on medication to enhance lipid reduction. Usually, statins such as atorvastatin and ezetimibe can be taken under the guidance of a doctor. Patients with hypercholesterolemia are advised to consult a doctor for standardized diagnosis and treatment when necessary, and to carry out standardized treatment under the guidance of a doctor.
