Triglycerides are components of lipids and their physiological function is mainly to store and provide energy. Normally, its concentration in the body is maintained within a certain range (less than 1.7 mmol/L), and hypertriglyceridemia is diagnosed regardless of the cause of triglycerides above 1.7 mmol/L. The degree of triglyceride elevation varies and so does the treatment. Mild elevations, if below 2.27 mmol/L, can be treated with aggressive lifestyle improvements such as physical activity and diet control. If the elevation is mild to moderate, with triglycerides between 2.27 and 5.65 mmol/L, pharmacological intervention should be given, either alone or in combination with statins, fibrates or niacin. If it is a severe elevation, with triglycerides greater than 5.65 mmol/L, lipid-lowering agents such as fibrates and niacin are required. A measured triglyceride of 4.3 mmol/L, which is significantly greater than 1.7 mmol/L, can be diagnosed as hypertriglyceridemia and needs to be treated with medication. Increased triglycerides are a major risk factor for cardiovascular diseases (such as stroke, angina pectoris, heart attack, coronary heart disease), and their levels are affected by age, gender and diet, so the treatment mainly includes: 1. low-fat diet, avoiding excessive intake of foods containing saturated fatty acids; 2. weight control and physical exercise; 3. you can use fibrates, such as fenofibrate, or statins, to reduce triglyceride levels; 4, quit smoking and limit alcohol.
