Alcoholic liver disease is a chronic liver disease caused by long-term excessive alcohol consumption, because all kinds of alcohol have different levels of alcohol, only 10% of the alcohol into the body from the gastrointestinal discharge, 90% are metabolized in the liver. The main component of alcohol is ethanol, which is oxidized to acetaldehyde after entering the liver cells. Both ethanol and acetaldehyde have toxic effects that directly stimulate and damage liver cells, and can cause fatty degeneration and even necrosis of liver cells. The main risk factors for alcoholic liver disease are related to the amount of alcohol consumed, years of drinking, gender, genetics, nutrition, and hepatitis B virus infection. So, how much alcohol and how long do you drink to cause liver disease? Most studies now believe that 48% of those who consume more than 40 grams of alcohol per day for more than 5 consecutive years will suffer from varying degrees of alcoholic liver disease; the risk of alcoholic liver disease increases 5-fold when 80D100 grams of alcohol are consumed daily; 25-fold when more than 160 grams are consumed daily; and 33% of alcoholics will develop alcoholic hepatitis and 14% will develop alcoholic cirrhosis if they continue to drink for 8 years and consume an average of 227 grams of alcohol per day. 14% develop alcoholic cirrhosis. The risk of drinking large amounts of alcohol at a time is greater than drinking small amounts of alcohol in small portions, and the risk of liver disease is higher when drinking at an early age. Women are more sensitive to alcohol than men. Women have a smaller body size and higher body fat content, so their blood alcohol concentration is higher than men’s when they drink the same amount of alcohol, and women have lower gastric ethanol dehydrogenase than men, making them more susceptible to alcoholic liver disease than men. Women are prone to change from alcoholic hepatitis to cirrhosis even after they stop drinking. Poor nutrition and protein deficiency can aggravate the toxicity of alcohol to the liver, so eating a moderate fat and high protein diet can reduce the toxicity of alcohol to the liver to a certain extent. However, dietary modifications are useless when excessive alcohol consumption exceeds the threshold of alcoholism. When chronic alcoholism occurs, patients will slowly find that their memory is not as good as before and their judgment is impaired; when they quit drinking, some patients will have hallucinations, hallucinations, mania and other mental abnormalities; their libido will decrease, and in serious cases, they may even become infertile; some people will develop diabetes; their appetite will decrease, and acute and chronic erosive gastritis, chronic pancreatitis and chronic cholecystitis will occur from time to time. Some patients will also be combined with arteriosclerosis, myocarditis, coronary heart disease; more damage is in the liver, about 75% occur fatty liver. Therefore, we must be careful when drinking alcohol, do not overdo it, so as not to cause liver disease, and of course, if you already suffer from liver disease, it is more important to avoid drinking alcohol, so as not to aggravate the disease.
