One of the causes: long-term alcohol abuse Alcohol is the number one killer that damages the liver. This is because when alcohol enters the body, it is mainly metabolized in the liver. The toxicity of alcohol to liver cells causes the breakdown and metabolism of fatty acids to become impaired, resulting in fatty liver deposits in the liver. The more alcohol you drink, the more serious the fatty liver will be, and it can also induce liver fibrosis, and then cause cirrhosis. Cause No. 2: Excess nutrition long-term intake of excessive animal fat, vegetable oil, protein and carbohydrates, these foods in the body can not be fully utilized, excess nutrients will be converted into fat storage, resulting in obesity, hyperlipidemia and fatty liver. The third cause of the disease: malnutrition obese people are prone to fatty liver, but it does not mean that thin people will not get fatty liver. Clinically, it is often found that some people are very thin but also suffer from fatty liver, which is due to long-term malnutrition, lack of protein and vitamins, which can also cause nutritional deficiency fatty liver. For example, chronic intestinal diseases, long-term anorexia, dieting, vegetarianism, malabsorption syndrome and gastrointestinal bypass surgery cause hypoproteinemia, lack of choline, amino acids or lipotropic substances, resulting in the accumulation of fat in the liver and the formation of fatty liver. Etiology No. 4: Diabetes, hepatitis, hyperthyroidism, severe. The body’s use of glucose decreases in patients with chronic diseases such as anemia due to insufficient insulin, and in order to replenish energy, the body’s fatty acids increase significantly, and these fatty acids cannot be fully utilized, which leads to hyper-synthesis of fat in the liver, thus causing fatty liver. 60% of obese patients develop diabetes, and their rate of fatty liver is two times higher than that of people without diabetes. Etiology No. 5: Drug-related liver damage Drug-related liver damage accounts for 1/10 of adult hepatitis, and fatty liver is a common type. Dozens of drugs are associated with fatty liver, such as tetracycline, acetylsalicylic acid, glucocorticosteroids, synthetic estrogens, amiodarone, nifedipine, certain antitumor drugs and lipid-lowering drugs, all of which can cause fat to accumulate in the liver. Etiology No. 6: hyperlipidemia hypercholesterolemia is closely related to fatty liver, of which hyper-TG (triglyceride)emia is the most closely related, and the vast majority are often accompanied by obesity, diabetes and alcoholism.
