Triglyceride measurement is a routine part of lipid analysis, and its normal range is 0.45-1.69 mmol/L. 1.7-2.25 mmol/L is called borderline hypertriglyceridemia, and greater than 2.25 mmol/L is called hypertriglyceridemia. So triglycerides 6.5 mmol/L, which are significantly elevated, are relatively serious. 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 triglycerides can maintain a dynamic balance within the plasma, but when excessive triglyceride intake or increased synthesis by the liver cells themselves, or after suffering from certain diseases, can lead to excessive triglycerides in the blood. Increased triglycerides are a major risk factor for cardiovascular diseases (e.g. stroke, angina, heart attack, coronary artery disease), which are influenced by age, gender and diet, and can increase the risk of acute pancreatitis if triglycerides are greater than 5.0 mmol/L. Generally, for patients with hypertriglyceridemia with a clear cause, treatment should be directed at the cause, with improvement of lifestyle preferred over oral medication, mainly including: 1) a light diet, avoiding the intake of high-sugar and high-fat foods; 2) weight control and strengthening physical exercise; 3) quitting smoking and alcohol. If the above-mentioned treatment is not effective or the value of triglyceride elevation is large, you should actively visit the hospital and choose reasonable and effective medication under the guidance of professional physicians.
