What are blood lipids? What are the dangers of high blood lipids?

Lipids are neutral fats and lipids found in human plasma. High blood lipids can endanger cardiovascular health and increase the incidence of arteriosclerosis, thrombosis, myocardial infarction, and cerebral infarction.

Blood lipids are a routine test item when people do blood tests, and it refers to neutral fats and lipids in human plasma. It is an important substance needed for the basic metabolism of human life cells, widely existing in the human body, most of the blood lipids that people usually say include two parts, one is triglycerides, and the other part is cholesterol.

Triglycerides are substances that are directly involved in the body's energy metabolism, but are used in the synthesis of cellular adhesive films. People have elevated blood lipids as they age or have a family history of the disease. People do not pay attention to diet in their daily life, often eat high-fat and high-calorie food, and do not exercise, resulting in obesity, which will also increase the risk of hyperlipidemia, and people will seriously endanger their health after the occurrence of hyperlipidemia.

High blood lipids will affect the aggravation of arterial health in humans, and the burden of cardiovascular and cerebrovascular systems is prone to atherosclerosis. When high blood lipids are not effectively controlled, it will also lead to a high incidence of acute pancreatitis, which will be life-threatening. When the cholesterol in anthropology is high, it will cause lesions in the blood vessels in the body, and arteriosclerosis will also occur, which will cause human carotid arteries and cerebral blood vessels, which will cause insufficient cerebral blood supply and stroke, which will leave sequelae and affect people's normal life if not timely.

When arteriosclerosis is caused by hyperlipidemia, coronary heart disease and myocardial insufficiency, as well as myocardial infarction and other diseases will also affect the arteries of the lower limbs, renal arteries and abdominal aorta in human beings, so that these arteries and blood vessels in the body will not be diseased, affecting the normal blood circulation in the human body, and will seriously threaten the health of the human body. Hyperlipidemia is a chronic disease, and there are no obvious symptoms in the body after the occurrence, so it is necessary to have a physical examination on time, find changes in blood lipids in time, and actively ** after the occurrence of hyperlipidemia, so as to avoid harm to the body due to high blood lipids.

Lipids are fats in the blood plasma; If the blood lipid is high, it will easily cause dizziness, nausea, weakness, and loss of appetite, and the damage to the cardiovascular and cerebrovascular vessels is very great.

A general term for triglycerides and lipidoids in plasma. It can lead to an increase in blood viscosity, it can also lead to a slowdown in blood flow, it can lead to coronary heart disease, and it can also lead to cerebral blood, renal insufficiency, and kidney failure.

This refers to the relatively high cholesterol, which will affect daily life, cause blood viscosity, and seriously affect blood circulation.

Blood lipids are a general term for lipids contained in plasma, such as triglycerides, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, lipoprotein A, lipoprotein B, etc., which are part of blood lipids.

There are two ** blood lipids, one is exogenous, that is, absorbed from the digestive tract; The second is endogenous, that is, it is mobilized by body fat or synthesized by the liver.

Hyperlipidemia is what we often call hyperlipidemia, which refers to an increase in the level of one or more of the total cholesterol, triglycerides, and low-density lipoprotein in the blood plasma. Hyperlipidemia may cause many complications and is one of the main causes of hypertension, hyperglycemia and other cardiovascular and cerebrovascular diseases.

Hyperlipidemia can cause endothelial damage to blood vessels, causing atherosclerosis, plaque in the inner wall of blood vessels, and narrowing of the lumen, affecting blood flow. Coronary artery plaque can lead to coronary artery stenosis, more than 50% of coronary artery stenosis can lead to angina symptoms, and in severe cases, myocardial infarction.

Blood lipids include triglycerides, cholesterol and lipids in the blood, and the first two types of blood lipids are commonly referred to. When triglycerides are severely elevated, acute pancreatitis is easy to induce. The increase in cholesterol levels, especially the increase in LDL cholesterol levels, is an important risk factor for atherosclerotic and cardiovascular diseases, which can increase the risk of coronary atherosclerosis and promote the formation of atherosclerotic plaques, so it is very closely related to the onset of coronary heart disease and cerebrovascular disease.

What are blood lipids? In human blood, the lipids contained in plasma are called lipids, including cholesterol, cholesteryl esters, triglycerides (triacylglycerides), phospholipids, and unfatated fatty acids.

The four blood lipid items we usually check are mainly triglycerides, total cholesterol, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol. When we talk about blood lipids, we mainly refer to triglycerides and cholesterol. Among them, cholesterol is divided into three types: high-density lipoprotein cholesterol, low-density lipoprotein cholesterol and very low-density lipoprotein cholesterol.

Blood lipids have a very important function in the human body. Triglycerides are important substances for energy supply and reserve in the human body, and triglycerides also play a role in fixing and protecting internal organs. Cholesterol is an important component of cell membranes, hormones, and bile.

It is necessary to maintain the normal physiological activities of the human body when the blood lipids reach a normal concentration, but if the blood lipids exceed the normal range, it will cause great harm to the human body, mainly reflected in cardiovascular and cerebrovascular diseases.

What we usually call the "three highs" refers to: hypertension, high blood sugar and high blood lipids, among which elevated blood lipids have become one of the main factors endangering the cardiovascular and cerebrovascular health of our people.

In recent years, the prevalence of dyslipidemia in the Chinese population has increased significantly, and dyslipidemia, which is characterized by elevated low-density lipoprotein cholesterol or serum total cholesterol, is an important risk factor for arteriosclerotic cardiovascular disease. Dyslipidemia also increases the incidence of diseases such as diabetes, fatty liver disease, and high blood pressure.

The harm of high blood lipids can lead to liver function damage, lead to high blood pressure, lead to coronary heart disease, and can harm coronary arteries.

1. Hyperlipidemia can lead to liver damage.

Long-term hyperlipidemia can lead to fatty liver, and after hepatic atherosclerosis, damage to the liver lobules, structural changes, and then lead to cirrhosis and damage to liver function.

2. High blood lipids can lead to high blood pressure.

After the formation of atherosclerosis in the human body, it will lead to myocardial dysfunction, and angiotensin-converting enzyme will be activated in large quantities, which will promote the spasm of blood vessels and arteries, induce adrenal glands to secrete vasopressin, resulting in an increase in blood pressure.

Once the human body forms high blood pressure, the blood vessels will often be in a state of spasm, and the cerebral blood vessels will be damaged by the endothelium after hardening, resulting in rupture, forming hemorrhagic stroke, and the cerebral blood vessels will stagnate in the emboli thrombosis, resulting in cerebral thrombosis and cerebral embolism.

3. Hyperlipidemia can lead to coronary heart disease.

When the human body forms atherosclerosis due to long-term hyperlipidemia, the blood flow in the coronary arteries becomes smaller, the lumen of the blood vessels narrows, and the amount of myocardial blood injection decreases, resulting in myocardial ischemia, resulting in angina pectoris, and coronary heart disease.

Fourth, hyperlipidemia can harm the coronary arteries.

Hyperlipidemia can harm the coronary arteries, form atherosclerosis, a large number of lipid proteins, deposition and move in the plasma, reduce the blood flow rate, and are deposited on the arterial vascular endothelium after rancidity through oxidation, and adhere to the blood vessel wall for a long time, damaging the arterial vascular endothelium, forming arteriosclerosis.

Blood lipid levels can be controlled with food:

From the perspective of nutrition, there is no distinction between good and bad food, and the balance and moderation of nutrition are the key. Whether it is grains, meat, vegetables and fruits, it is necessary to grasp the degree of intake.

If a certain type of food is rich in nutrients, eating a large amount of this food is not conducive to the balance of human nutrition. For fatty meats with high animal fat, offal foods with high cholesterol or liquor, people can't do it all the same, as long as the amount of these foods is controlled.

The average adult synthesizes about 1,000 mg of cholesterol per day, while the direct intake of cholesterol from food is 300 to 500 mg. For patients with hypercholesterolemia, dietary cholesterol should be limited to less than 200 mg.

The main cholesterol is animal food, and since most of the cholesterol is synthesized in the liver and intestines, it is important to control the amount of this type of food when ingesting. In addition to this, animal brains, egg yolks, fish roe, crab roe and squid are foods that are rich in cholesterol and should be strictly limited.

The harm of high blood lipid is very great, high blood lipids, it includes an increase in total cholesterol, an increase in triglycerides, or both are high, this situation is harmful, the main harm of blood lipid elevation is that it may lead to high blood pressure, coronary heart disease, obesity, especially may accelerate arteriosclerosis, it is easy to lead to an increase in blood pressure, after the blood pressure rises, accompanied by an increase in blood lipids, it is easy to damage the blood vessel wall, lipid deposition, intravascular plaque formation, blood vessel stenosis, if it is said to occur in the coronary arteries, That is coronary heart disease, which may cause the onset of myocardial ischemia, so high blood lipids are very harmful.

When it comes to hyperlipidemia, the first thing that comes to people's minds is a person with a big belly and a shiny face. In fact, people with hyperlipidemia may be like this, but not everyone with hyperlipidemia has this characteristic. Hyperlipidemia is not due to obesity in the body, but because the blood lipid content in the blood vessels exceeds the normal value.

In addition, people should not underestimate the health risks caused by high blood lipids, which are more harmful than you can imagine. The damage of hyperlipidemia to the human body is insidious, gradual, and systemic.

People with high blood lipids, if not timely, may cause some harm to the liver, just like fatty liver. Long-term hyperlipidemia can cause liver lesions, especially atherosclerosis of the hepatic arteries, which can cause liver function or organic damage and antagonia, thus causing liver cirrhosis.

Hypertension is a vascular disease related to vascular volume, constriction and relaxation of blood vessel walls. For people with high blood lipids for a long time, the blood lipids in the blood will accumulate in the blood vessels, which is like a layer of "grease", which will narrow the blood vessels and cause blood pressure to rise. In addition, hyperlipidemia can also cause atherosclerosis, which can cause metabolic disorders of myocardial function, which will cause certain harm to the heart.

If the body is in a state of high blood pressure for a long time, there is a high risk that blood vessels will rupture and bleed, which will cause irreparable damage to vital organs such as the brain.

The coronary arteries are the main blood supply arteries to the heart, and if the blood lipid level is too high for a long time, then the lumen of the blood vessels will narrow, which will lead to the blockage of the important blood supply channels to the heart, which can lead to coronary heart disease. As coronary blood circulation continues to decline, the blood supply to the myocardium decreases, and myocardial ischemia can lead to myocardial ischemia, with discomfort in the precordial area in the early stage, and then symptoms such as angina. The lungs are closely related to the heart, and once the function of the heart is impaired, the function of the lungs will also be impaired, and patients with poor cardiopulmonary function are likely to develop cardiopulmonary failure.

Hyperlipidemia can cause atherosclerosis, and in severe cases, it can cause coronary heart disease, stroke, vision loss, blindness, renal arteriosclerosis, kidney failure, etc. In addition, hyperlipidemia can cause hypertension, induce gallstones, pancreatitis, aggravate hepatitis, lead to male sexual dysfunction, Alzheimer's disease and other diseases. Recent studies suggest that hyperlipidemia may also be associated with the onset of cancer.

Hyperlipidemia can occur at any age and can affect the health of patients, leading to acute pancreatitis, impaired liver function, atherosclerosis, hypertension and other hazards.

1.Acute pancreatitis: The level of triglycerides in the blood of patients with hyperlipidemia will be relatively high, and it will accumulate in the pancreas, and pancreatic enzymes will produce too many fatty acids when breaking down triglycerides, and they cannot fully bind to proteins, resulting in toxicity and acute pancreatitis.

2.Impaired liver function: patients with hyperlipidemia have high body fat content, and some fat will accumulate in the liver, increasing the risk of fatty liver disease, causing liver cirrhosis and impaired liver function.

3.Athesclerosis: High blood lipids will cause the fat and cholesterol content in the human blood to be too high, and accumulate in the inner wall of blood vessels, gradually forming atherosclerosis, resulting in narrowing of the lumen of blood vessels or rupture of blood vessels, which will increase the risk of myocardial infarction, cerebral infarction, coronary heart disease and other diseases.

4.High blood pressure: The patient's blood lipid content is elevated, which in the long run can cause vascular lesions, leading to narrowing of blood vessels and high blood pressure.
