Cholesterol 6.26 mmol/L does not always require medication. It can be treated by lifestyle improvement or medication. The normal reference value for cholesterol is less than 5.2mmol/L, and more than 6.2mmol/L is an elevated level of cholesterol. If there are no risk factors such as coronary heart disease, hypertension, diabetes, etc. lifestyle intervention can be carried out first, including dietary avoidance of oily and high-salt foods, smoking and alcohol cessation, and maintenance of appropriate aerobic physical exercise. If the above measures are ineffective, or if the patient also has risk factors for cardiovascular disease, it is necessary to take medication to strengthen lipid-lowering, which can take atorvastatin, ezetimibe, kaufenamide and other drugs under the guidance of a doctor. It is recommended to consult a doctor for standardized diagnosis and treatment when necessary.
