The normal range of triglycerides is 0.45-1.69 mmol/L. According to the 2007 “Guidelines for the Prevention and Treatment of Dyslipidemia in Chinese Adults”, fasting (12 hours fasting) triglycerides below 1.70 mmol/L is considered appropriate, 1.70-2.25 mmol/L is considered borderline elevated, and greater than or equal to 2.26 mmol/L is considered elevated. Therefore, triglycerides of 4.5 mmol/L, which are significantly elevated, can be diagnosed as hypertriglyceridemia, which is a more serious condition. Triglycerides are components of lipids, whose main function is to supply and store energy and participate in biochemical metabolism and substance synthesis in the body. Under normal conditions, it is maintained in dynamic balance in the blood plasma. When excessive triglyceride intake or certain diseases, or increased synthesis by the liver cells themselves, can lead to excess triglycerides in the blood. The degree of triglyceride elevation varies and so does the treatment. If it is below 2.27 mmol/L, it can be controlled by lifestyle improvements, such as physical activity and a low-fat diet. If triglycerides are between 2.27 and 5.65 mmol/L, medication should be given, either alone or in combination with statins, fibrates or niacin. If triglycerides are greater than 5.65 mmol/L, treatment with lipid-lowering drugs such as betablockers and niacin is required. So triglycerides of 4.5mmol/L need to be intervened with medications, either fibrates, such as fenofibrate, or statins, to lower triglyceride levels. In addition, active lifestyle improvement is needed, including weight control, reasonable diet, restriction of alcohol consumption, moderate exercise, and smoking cessation.
