What are cholesterol and triglycerides?

Cholesterol and triglycerides are often heard in life. Some people have high cholesterol and triglycerides, while others have low cholesterol and triglycerides. Whether high or low, they will have adverse effects on the body. It is harmful to our health, so we must treat it in time if a problem occurs, but what are cholesterol and triglycerides? We have only heard some partial information but don't know the specific situation. It is necessary for us to understand this because things related to physical health are very important.

Triglycerides are the most abundant lipids in the human body. Most tissues can use the decomposition products of triglycerides to supply energy. At the same time, tissues such as the liver and fat can also synthesize triglycerides and store them in adipose tissue. Triglycerides are an important indicator in blood lipid examination.

His index directly measures a person's health status, and the serum triglyceride level is 0.45-1.70mmol/L. That is to say, there are 2.3 billion people with dyslipidemia in my country, which is mainly due to the significant changes in dietary structure and lifestyle in the past 10 years. Dyslipidemia has become the biggest health risk for Chinese people. Moreover, the dyslipidemia of Chinese people is different from that of Europeans and Americans (mainly characterized by increased low-density lipoprotein (LDL)). The most common clinical manifestation is increased triglycerides (TG).

Low-density lipoprotein cholesterol, which is a combination of low-density lipoprotein and cholesterol, is an important factor leading to arteriosclerosis. The higher its level, the greater the possibility of arteriosclerosis. Low-density lipoprotein cholesterol is often called "bad" cholesterol. Normal value: 2.07-3.12mmol/L.

High-density lipoprotein and cholesterol combine to form high-density lipoprotein cholesterol, which acts like a scavenger in blood vessels, transferring cholesterol from tissues to the liver. It has the function of preventing and treating atherosclerosis and is also called "good" cholesterol. The normal value is 0.94-2.0mmol/L.

Blood lipids are the general term for various lipid substances in the blood. The most important of these are cholesterol and triglycerides. Triglycerides are fats. They are insoluble in water and combine with proteins to form lipoproteins, which circulate in the blood. Mild increase in triglycerides may be caused by excessive intake of sugary foods, smoking, obesity and other factors.

Severe high triglycerides are often related to diabetes, liver disease, chronic nephritis, etc., and are generally secondary diseases.

To sum up, we have a specific understanding of what cholesterol and triglycerides are. We know that if high cholesterol and triglycerides occur, it will lead to more diseases, such as diabetes, gastritis, etc. However, high cholesterol and triglycerides are caused by bad living habits. Some people often stay up late and never eat three meals on time, which is not good.
