A, bad mood: Chinese medicine cloud: “worry hurts the spleen, anger hurts the liver.” When people have violent mood swings, the hormone secretion in the body is out of balance, resulting in impaired blood circulation, affecting the blood supply to the liver, causing liver cells to die due to ischemia. We also often encounter some in the Chinese clinical due to family conflicts, poor work, lost love, etc. caused by liver disease, or lead to liver disease aggravated relapse of people. Second, alcohol: as the saying goes, more alcohol hurts, this is because alcohol is a very strange molecule, both soluble in water, but also soluble in oil, once into the body will be like a fish, of course, the first bad luck is the liver. Because alcohol itself contains toxicity, enough to harm the liver, fatty liver is the earliest signs, just a few days of drinking can be formed, then lead to “fibrosis”, and then become alcoholic liver disease, and then the situation is worse, and eventually developed to irreversible “cirrhosis of the liver “This is what we see in clinical practice. This is our common clinical alcoholic liver disease, especially long-term heavy drinkers (alcoholics), more likely to occur. Third, drugs: survey data show that drug-induced liver damage accounts for about 10% of hospitalized patients. It is reported that 43% of patients over 50 years of age with “acute hepatitis” are caused by drugs. Drugs such as aspirin, sulfonamide, penicillin, rifampin, and acetaminophen are commonly used and harmful to the liver. Even those seemingly safe drugs, such as nutritional drugs and supplements, can also be misused or abused to lay hidden dangers for the liver. Hepatitis virus: at the top of the list of “natural enemies” of the liver. In other words, hepatitis viruses are the primary enemy of liver health, and they often drag sufferers into the hepatitis – cirrhosis – liver cancer road to death. At present, scientists have found five types of hepatitis viruses such as A, B, C, D, E, etc., of which B, C, E and other models are the most common and the most harmful. Five, obesity: under normal circumstances, the liver itself contains only a small amount of fat, accounting for about 4-7% of the liver, if the fat content in the liver accounted for more than 10%, can cause impaired liver function, medically called fatty liver, deterioration is cirrhosis, and even liver cancer. Obesity is not only a threat to adults, but also a major “culprit” of fatty liver in children. According to experts, the incidence of fatty liver in “fat children” is as high as 80%. And obesity is often closely related to fatty liver, hypertension, diabetes, etc., clinically known as metabolic syndrome, seriously endanger human health. Six, food contamination: there is such a class of people, no hepatitis any symptoms, but when checking the blood shows a single transaminase elevated, what is the reason? Many experts have suggested that food contamination may be to blame. Food contamination includes pesticide residues of vegetables, fruits and vegetables; certain food additives, such as flour whitening agents, preservatives; water pollution, such as some chemical toxic substances on drinking water pollution; smoked food and spoiled food, such as rotten ginger, reddened lantern, long sprouted potatoes, etc.. Although food contamination is not so harmful in a short period of time, the accumulation of long-term chronic toxic effects can completely impair liver function.
