According to the 2007 “Guidelines for the Prevention and Treatment of Dyslipidemia in Chinese Adults”, a fasting (12-hour fast) triglyceride level of 1.70 mmol/L or less 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 3.26mmol/L are significantly elevated. Triglycerides are components of lipids, and their main function is to supply and store energy and participate in biochemical metabolism and substance synthesis in the body. Under normal conditions, triglycerides are maintained in dynamic balance in the blood plasma. When excessive triglyceride intake or increased synthesis by hepatocytes themselves, or after suffering from certain diseases, it can lead to excessive triglycerides in the blood. Increased triglycerides are positively correlated with atherosclerosis and can easily induce cardiovascular disease, so they should be actively treated and improved. In the case of mildly elevated patients, the first choice is not medication but improvement of lifestyle, including weight control, reasonable diet, limiting alcohol consumption, moderate exercise and quitting smoking, etc. Most patients’ triglyceride index can be reduced to normal level. If the patient’s condition is serious and the triglyceride level is greater than or equal to 5.65 mmol/L, then drug therapy, such as fibrates and niacin, should be the first choice, while paying attention to diet and lifestyle modifications.
