High blood fat can leave dangerous complications affecting the health of the heart, liver and kidneys. If not controlled, the harmful effects of blood fat can have unfortunate consequences.
1. Characteristics of dyslipidemia
Cholesterol and triglycerides are two basic components of blood fats. There are 3 types of cholesterol: good cholesterol, bad cholesterol and total cholesterol.1.1. Features of cholesterol
Cholesterol is a fatty substance found in the cell membranes of all tissues in the body and transported in the blood plasma of the human body. A large part of cholesterol is synthesized by the liver from saturated fats, a small part of cholesterol is absorbed from foods that we tolerate daily such as eggs, meat, milk, animal fat, beef, shrimp, fish.The characteristics of cholesterol are poorly soluble in water, they practically cannot dissolve and move and move in the blood. Cholesterol must be made up of lipoproteins, a substance synthesized by the liver and dissolved in water that carries cholesterol.
The functioning of cell membranes in the body requires cholesterol to produce hormones. On the other hand, this is also the component of bile salts. Good cholesterol (HDL-C) plays a role in making artery walls soft for efficient blood circulation, while also having the ability to protect blood vessel walls. In contrast, bad cholesterol (LDL-C) causes atherosclerosis.
1.2. Features of triglycerides
Triglycerides are substances caused by excess of fatty acids that are not converted to cholesterol in the liver (when free fatty acids are absorbed by the liver, they will be converted to cholesterol. On the contrary, if there is an excess of fatty acids, they will become triglycerides). . In the liver, triglycerides will combine with apoproteins and be removed from the liver as low-density lipoproteins.

2. Causes of hyperlipidemia
The main cause of hyperlipidemia is due to eating habits as well as maintaining an unhealthy lifestyle, especially in adults. Therefore, hyperlipidemia is common in the elderly.In particular, the state of blood fat increases due to a diet containing a lot of animal fat, animal organs, egg yolks, butter, milk, and red meats in daily meals.
In addition, a major cause of hyperlipidemia is a history of obesity, sedentary lifestyle or people with diabetes. With high triglyceride status, it is common in people who drink a lot of alcohol, genetic or metabolic gene disorder.

3. What harm does high blood fat cause to health?
Although dyslipidemia (dyslipidemia) does not directly cause death for the patient, the consequences of this disease are not inferior to any fatal diseases. Therefore, it is very important to recognize the danger level of blood fat to the body. Some of the harmful effects of blood fat on the body can be mentioned as:3.1. High blood fat affects the heart
High blood fat is the main cause of atherosclerosis, if this condition is prolonged, it causes narrowing of the arteries, reducing the blood supply to the heart. Especially if both cholesterol and triglyceride levels increase, the dangerous level of the disease can become severe, accelerate the process of atherosclerosis, consequent myocardial ischemia, myocardial infarction and death.

3.2. High blood fat causes brain stroke
High blood fat, especially in people with high cholesterol, causes deposition in the vessel walls to form atherosclerotic plaques. Accordingly, atherosclerotic plaques migrate from other places to or form right at the cerebral blood vessels, thereby narrowing the lumen and leading to a decrease in blood flow and causing cerebral ischemia. More seriously, blood to the brain can be blocked, causing a stroke. There have been many statistics showing that up to 93% of stroke patients have a history of dyslipidemia.3.3. High cholesterol affects blood pressure
High blood fat causes plaque to narrow, narrowing the vessel wall, making the vessel wall less elastic, thereby increasing the pressure on the blood vessel wall.In order to provide adequate blood for the body's activities, it is imperative that the heart work harder. This increases heart rate, increases myocardial contractility, increases water absorption and retention in the body, leading to high blood pressure.
3.4. High cholesterol causes fatty liver disease
The main cause of obesity is an improper diet. Accordingly, the entire food that is tolerated is metabolized by the liver, causing fatty liver. Fatty liver is the accumulation of fat in the liver in excess of 5% of its weight. Fatty liver disease often has no obvious symptoms, so it is difficult for patients to recognize. In the long term, fatty liver reduces liver function and causes many other hepatobiliary diseases.

3.5. High blood fat reduces physiological function
High blood fat not only affects the organs in the body but also affects the sex life of both sexes. According to statistics, 80% of cases of men with hypercholesterolemia have erectile dysfunction and this manifestation is earlier than cardiovascular complications in patients with high blood fat. In addition, high cholesterol also reduces libido in women.In the past, dyslipidemia was only common in the elderly, but now this disease has a tendency to be younger. Even dyslipidemia has been reported in patients in their 20s. Therefore, prevention. lipid disease to limit the risk of disease in the future is very important.

4. How to prevent hyperlipidemia
To prevent hyperlipidemia, maintaining a healthy diet and lifestyle is very important. Accordingly, to limit the increase of blood fat, you should limit the use of greasy fried foods, animal organs, red meats, animal skins, do not smoke, do not drink alcohol .. Instead, you can use vegetable oils, olive oil, soybean oil, eat fish instead of meat. Increase the addition of green vegetables, fruits to provide fiber, vitamins and minerals. These nutrients help the digestive system to function properly and eliminate toxins.Besides nutrition, exercise is also very important. Daily, you should increase your regular exercise or play gentle, healthy sports such as walking, playing badminton. , read books, practice yoga, club activities.
Finally, people with hyperlipidemia need periodic health check-ups to perform tests. From there, the doctors will have appropriate advice, examination and treatment, minimizing the risk of complications of high blood fat that can cause.
