Total cholesterol of 5.33mmol/L is a borderline elevation, which is generally not serious and can be normalized through improved lifestyle intervention. Total cholesterol, including free cholesterol and cholesteryl esters, is the sum of cholesterol contained in all lipoproteins in the blood. The Chinese Guidelines for Prevention and Control of Dyslipidemia in Adults recommend that the appropriate level of total cholesterol should be less than 5.2 mmol/L, with a borderline elevation of 5.2-6.19 mmol/L, and a higher level of 6.2 or more. A total cholesterol level of 5.33mmol/L is only borderline elevated and is not serious. With a low-fat diet, limiting cholesterol intake, limiting saturated fatty acid intake, increasing exercise, and abstaining from smoking and drinking, most patients can return to normal. If necessary, oral lipid-lowering drugs (atorvastatin) can also be used. High blood lipid is a common disease, it is recommended to maintain a healthy lifestyle, and medication should be used under the guidance of a medical professional.
