The total cholesterol is normal, but what is the reason for the high triglyceride?

Total cholesterol is normal, but triglycerides are high. Is this normal? Of course, it is normal, and the value of triglycerides is not completely related to total cholesterol.

First of all, these two concepts-total cholesterol (TC)-refer to the sum of cholesterol contained in lipoprotein in human blood. In addition to low-density lipoprotein and high-density lipoprotein cholesterol, blood lipid examination indexes also include chylous protein, very low-density lipoprotein and cholesterol contained in lipoprotein (a). Therefore, although TC value can also reflect the risk of atherosclerosis, it is not as accurate as LDL-C.

Triglyceride (TG)-It is a chemical substance, which refers to the combination of glycerol and three fatty acids. It is the main component of two kinds of lipoproteins in blood: chylous protein and very low density lipoprotein. The check value of TG refers to the total amount of triglycerides contained in all lipids in serum.

Therefore, it is completely normal and reasonable that the total cholesterol in the physical examination report is normal and the triglyceride is high.

What is high triglyceride? For the case of high triglyceride, the influence of external factors should be excluded first. Among the indexes of blood lipid examination, this value is most influenced by external factors. Other indexes are less affected by diet and determination time, but triglycerides are more affected by these factors. The TG values measured by the same person at different times may vary greatly.

For example, if you have been eating greasy food and drinking alcohol for several days before the examination, the high triglyceride measurement may be caused by diet. Stick to a light diet, don't drink for a while, and then check, this value may return to normal.

Since it is so influenced by the outside world, is the measured TG meaningless? Of course not. The increase of TG reflects the increase of very low density lipoprotein and its residual particles. The increase of these values will increase the risk of atherosclerosis. At the same time, the increase of TG will also affect the structural changes of low-density lipoprotein and high-density lipoprotein, and increase the risk of vascular occlusion. In addition, severe TG elevation, such as higher than 5.8, is usually accompanied by symptoms of acute pancreatitis.

If there are no external factors, we should pay attention to the abnormal increase of TG. Generally speaking, for the mild and moderate increase of TG, it is generally recommended to adjust life, including light diet, less greasy food, more fruits, vegetables and coarse grains rich in dietary fiber, weight control, moderate exercise, smoking cessation and alcohol restriction, especially hard liquor. These are all good ways to regulate triglycerides. If there is a serious increase, you can choose fibrates.
