Cholesterol 5.25 mmol/L suggests a borderline level, which is slightly elevated and not too high. Cholesterol is one of the components of lipids and can be divided into cholesteryl esters and free cholesterol, where cholesteryl esters and free cholesterol are collectively referred to as total cholesterol. The cholesterol test result is generally referred to as total cholesterol. The appropriate level of total cholesterol is generally <5.20 mmo/L; if total cholesterol is 5.20 to 6.20 mmol/L, it is borderline elevated. Therefore cholesterol 5.25mmol/L suggests a borderline level, which is not too high. Elevated total cholesterol levels increase the risk of atherosclerosis, which in turn increases the risk of coronary heart disease and stroke. You can help avoid continued elevation of cholesterol by reducing intake of pork, beef and mutton, especially the fatty meat and offal of pork, beef and mutton, and eating more vegetables, fruits and coarse grains, and eating chicken, duck and fish. If elevated cholesterol levels are detected, treatment and intervention under the guidance of a doctor is recommended to reduce the risk of cardiovascular diseases.
