Although there are no statistics on the incidence of alcoholic liver disease in China, clinical observation shows that the incidence of the disease is on the rise. Alcoholic liver disease is very insidious in its onset, and when the disease is not very serious, patients hardly feel anything. Because of this, the early diagnosis rate of alcoholic liver disease is very low. Many patients with alcoholic liver disease already have cirrhosis when they are first diagnosed, but before that, they don’t even know they have liver disease. In the “drinking” problem, there are many misconceptions among the people, for example, some people believe that drinking white wine is more harmful to the liver, drinking beer or red wine is less harmful to the liver, so there is no need to limit the latter two kinds of wine; some people have heard that drinking red wine can prevent cardiovascular disease, they take red wine as a health product, every day to drink half a bottle a bottle; others like to eat before drinking; Some people like to take some antidote or liver medicine before drinking, thinking that this will “protect the liver”, you can drink with confidence. In fact, no matter what wine, as long as you drink too much, will be harmful to the liver. As for the so-called liver protection drugs. The alcoholic liver disease can not be prevented by the antidote. So, how much alcohol is considered safe to drink? For individuals, this number varies greatly. It is generally accepted that alcoholic liver disease is likely to occur after consuming 40-60 grams of alcohol per day and 120-180 grams of alcohol per week for more than 5 years. It is especially important to note that several cases of acute alcoholic hepatitis occurring as a result of a single large intake of alcohol are encountered each year, and a few are particularly severe and eventually die from liver failure.
