Total cholesterol of 6.29 mmol/L and LDL of 4.34 mmol/L is a high lipid profile and requires standardized treatment to control the lipid levels. Clinically, the normal total cholesterol value should be less than 5.2mmol/L and the LDL level should be less than 3.4mmol/L. The present reading is high and needs to be treated. If the blood lipid is high and there is no other abnormality, you can control the diet first and observe the decline afterwards; if it is accompanied by atherosclerosis and other diseases, you need to apply lipid-lowering drugs (simvastatin, lovastatin, atorvastatin, etc.) to control it. The occurrence of high blood lipid should be timely medical examination and standardized treatment under the guidance of the doctor, to avoid causing delays in the condition.
