Blood lipids include four indicators, namely total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides. The normal reference range for triglycerides is 0.45-1.69 mmol/L. Fasting, i.e., fasting for 12 h, is considered appropriate for triglycerides below 1.70 mmol/L, borderline elevated for 1.70-2.25 mmol/L, and elevated for more than 2.26 mmol/L. If the patient’s triglycerides are currently 5.5 mmol/L, this situation is relatively serious and the following treatment is recommended: 1. Lifestyle changes: weight control, overweight and obese patients should reduce their body weight by 5-10%; control total dietary calories, control the amount of carbohydrates and fat intake, increase the amount of vegetables and high-quality protein food; limit alcohol consumption, and those with severely elevated triglycerides should immediately 2.After lifestyle intervention, triglycerides still cannot be satisfactorily controlled should be considered for drug treatment. Currently, the commonly used lipid regulating drugs include statins, fibrates, niacin, ω-3 fatty acids and cholesterol absorption inhibitors. Although statins can significantly lower total cholesterol and LDL cholesterol, their effect on triglycerides is relatively weak. Betaines, niacin and omega-3 fatty acids have significant lowering effects on triglycerides and are recommended for dyslipidemic patients with predominantly elevated triglycerides.
