TG stands for triglycerides, which is one of the lipid tests. If patients have high triglycerides for a long time, it can lead to fatty liver, pancreatitis and even liver cirrhosis and liver cancer in some people. Therefore, in clinical practice, if hypertriglyceridemia exists, lifestyle interventions must be actively given, such as advising patients to exercise to lose weight, eat a low-salt, low-fat diet, eat more fresh fruits and vegetables, and quit smoking and alcohol, so that triglycerides can be further controlled smoothly. If triglycerides cannot be lowered to normal levels simply through lifestyle intervention, patients are advised to initiate lipid-lowering drug therapy, and the preferred triglyceride-lowering drugs are mainly beta-lipid-lowering drugs, with benzofibrate and fenofibrate as representative drugs. If the TG exceeds 5 mol/L, there is a possibility of pancreatitis and active treatment is needed; in addition, the TG is greatly influenced by diet, so it is recommended to have a light diet for 3 days before the blood test.
