Fatty liver refers to the pathological changes of excessive fat accumulation in liver cells caused by various reasons. Fatty liver disease is seriously threatening the health of Chinese people, becoming the second largest liver disease after viral hepatitis, and has been recognized as a common cause of covert cirrhosis. Fatty liver is a common clinical phenomenon, not a separate disease. Its clinical manifestations are asymptomatic in mild cases and severe in severe cases. In general, fatty liver is a reversible disease. Early diagnosis and timely treatment often return to normal.
With the improvement of people s living standards and changes in dietary structure, the incidence of fatty liver known as the modern rich and noble disease has increased significantly in China. A recent survey showed that the incidence of fatty liver in people around the age of 30 in Guangzhou was 20% to 30%, the incidence of fatty liver in a university in Shanghai was 8.8%, and the incidence of fatty liver in a university in Beijing was 11%. What kind of disease is fatty liver? What harm does it have on human health? How to prevent and treat fatty liver? On these issues, the reporter interviewed Dr. Hou Peng, director of the Gastroenterology Department of the PLA 304 Hospital.
Dr. Hou Yi started with the function of the liver. He said that the liver is the largest chemical plant in the human body, and it carries important functions such as digestion, detoxification, and secretion, which cannot be separated from human life. The nutrients we eat in three meals a day must be processed by the liver in order to provide the needs of human life activities. It can be said that the human body has no liver, there is no life, the liver is damaged, and health will suffer. Therefore, caring for the liver is caring for life.
Dr. Hou Hou said that normal human liver tissue contains a small amount of fat, such as triglycerides, phospholipids, glycolipids, and cholesterol, and its weight is about 4% to 5% of the liver weight. If, for some reason, excessive accumulation of fat in the liver exceeds 10% or even 15% of the weight of the liver, it is called fatty liver.
When talking about the etiology of fatty liver, Dr. Hou said that the increased incidence of fatty liver is closely related to the improvement of people s living standards and changes in dietary structure. Including nutritional disorders, heavy drinking, diabetes, hepatitis, metabolic and endocrine disorders and many other reasons.
One of the causes: chronic alcoholism. After alcohol enters the body, it is mainly catabolized in the liver. The toxicity of alcohol to liver cells causes liver cells to impair the decomposition and metabolism of fatty acids, causing fatty deposition in the liver and causing fatty liver. The more you drink, the worse your fatty liver becomes.
Cause two: excess nutrition. Long-term intake of excessive animal fats, vegetable oils, proteins and carbohydrates, these foods can not be fully utilized in the body, excess nutrients are converted into fat storage, resulting in obesity, hyperlipidemia and fatty liver. A Heilongjiang study showed that the incidence of fatty liver in severely obese children is as high as 80%, that is, 8 out of 10 fat pier.
Cause three: malnutrition. Dr. Hou emphasized that obese people are prone to fatty liver, but it does not mean that lean people will not get fatty liver, and it is often found clinically that some people are thin but also suffer from fatty liver. Long-term malnutrition and lack of certain proteins and vitamins can also cause nutritionally deficient fatty liver.
