The normal range of triglycerides is 0.45-1.69 mmol/L. 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 3.7 mmol/L is a high level and is a more abnormal condition. Triglycerides are a component of lipids and their main function is to supply and store energy, and they also participate in biochemical metabolism and substance synthesis in the body. Under normal circumstances triglycerides can be maintained in dynamic balance in the plasma, but if excessive triglyceride intake, increased synthesis by the liver cells themselves, or certain diseases, triglycerides in the blood can occur in excess of the standard. In patients with hypertriglyceridemia due to a clear etiology, treatment should be directed at the cause. The first choice is to improve lifestyle rather than oral medication, including weight control, reasonable diet, limiting alcohol consumption, moderate exercise, and quitting smoking, etc. The triglyceride index can be reduced to normal levels in most patients. However, after a period of improving behavioral treatment, the effect is not good or there is a tendency of aggravation, active oral medication should be taken, and the preferred lipid-lowering drugs are beta-lipid-lowering drugs, such as benzofibrate and fenofibrate. Because elevated triglycerides are the main risk factors for cardiovascular diseases (such as stroke, angina, heart attack, coronary heart disease), they should be treated positively and promptly checked at the hospital for reasonable and effective advice from a professional physician.
