Hyperlipidemia can be divided into four types clinically, namely hypercholesterolemia, hypertriglyceridemia, high-density lipoprotein cholesterolemia, and mixed hyperlipidemia. Among them, low-density lipoprotein cholesterolemia is the focus of our attention, because it is the most important risk factor for cardiovascular and cerebrovascular diseases such as cerebral infarction and myocardial infarction.
For a normal person's hyperlipidemia diagnostic criteria are triglycerides greater than 1.7, total cholesterol greater than 5.7, LDL greater than 3.4, you can call hyperlipidemia patients, I believe many people will ask what causes hyperlipidemia, and the main causes of hyperlipidemia are the following three.
First, improper diet. Many people in their daily life if the intake of excessive saturated fatty acids in food, such as pork, beef, lamb, or cholesterol-rich foods, and many young people will also ingest foods rich in trans fatty acids, such as cream cake, puffs, milk tea, which of course will cause this part of the people's blood lipids to rise.
For vegetarians, if you eat too many carbohydrates and proteins, you will produce extra calories that our human body does not need, and the excess calories will be stored in the form of triglycerides in fat, which will cause hyperlipidemia, so for vegetarians in ordinary life, if they do not pay attention to dietary regulation, they will also get hyperlipidemia.
Second, do not love sports. As I said in previous videos, the highest risk factor for the risk of cardiovascular and cerebrovascular diseases is not to love sports, especially for those who do not love sports and do not adhere to sports, through blood testing, their blood lipid content is significantly higher than that of some manual workers and those who insist on physical exercise. Because when we are engaged in manual labor or physical exercise, our body definitely needs to consume some lipids to supply energy, which makes our blood lipids lower.
Third, genetic factors. A small number of patients with hyperlipidemia have familial onset, which is mainly caused by genetic defects, so for patients with several immediate family members in the family who have hyperlipidemia, it is necessary to pay great attention to this time, it is best to go to the hospital to check whether they have hyperlipidemia.
In fact, everyone has a misunderstanding about blood lipids is that hyperlipidemia is exclusive to fat people, and people who are emaciated will not get hyperlipidemia. In fact, I want to tell you that thin people can also get hyperlipidemia, and the harm may be greater. Because genetics, certain metabolic diseases and other reasons can cause elevated blood lipids, so even thin people can suffer from hyperlipidemia. At the same time, because thin people have no defensive mentality against this, experts remind that thin people must also pay attention to their own blood lipids to prevent the occurrence of cardiovascular diseases.
The main diseases that cause hyperlipidemia are: First, hypothyroidism, thyroid hormones can promote cholesterol metabolism, when the body has hypothyroidism, it will lead to hypercholesterolemia. Second, nephrotic syndrome, typical nephrotic syndrome is mainly manifested as edema, large amounts of proteinuria, hypoproteinemia, hyperlipidemia and other symptoms. Third, Cushing syndrome, due to the increase in glucocorticoids in patients affects blood lipid metabolism, but also prone to hyperlipidemia.

Finally, it must be emphasized that the high blood lipids of thin people are often more harmful, and the characteristics of high blood lipids in thin people are often high in LDL cholesterol, while HDL cholesterol levels are low. This situation is very unfavorable to the prevention of atherosclerotic cardiovascular and cerebrovascular diseases, so thin people also have to regularly do a good job of blood lipid testing.
Well, today I will talk so much, pay attention to medical science, pay attention to dr. Zeng of neurology.
