Alcoholic liver disease does not only refer to the commonly mentioned “alcoholic liver”, which is also known as alcoholic fatty liver, but also includes a series of progressive damage to the liver when exposed to alcohol, including the following three main types: 1. alcoholic fatty liver, 2. alcoholic hepatitis, and 3. cirrhosis. These three types progress gradually and can eventually even lead to the development of liver cancer. As such, alcoholic liver disease should not be underestimated and is not necessarily less harmful than viral hepatitis. So just how much alcohol is consumed on average daily to cause alcoholic liver disease? Adult healthy men: The latest research shows that the average intake of 40-80g of ethanol (the chemical component of alcohol) per day in normal adult men can lead to alcoholic liver, and when 160g of ethanol is consumed daily for 10-20 years, it can lead to alcoholic hepatitis and liver cirrhosis. Generally, one glass of 4.8% beer (about 285ml), one glass of 40% white wine (30ml), and one glass of 13% red wine (100ml) contain about 10g of alcohol (as shown in the figure). This means that the incidence of alcoholic liver disease is significantly higher in adult men when their average daily alcohol consumption is: 4 glasses of beer, 4 small glasses of white wine, or 4 tall glasses of red wine. Adult healthy women: The global prevalence of alcoholic liver disease is significantly higher in men than in women, but this does not mean that women are less likely to get the disease, it is just shaped by the high rate of alcoholism in men. In fact, women are more likely to develop alcoholic liver disease, which can be triggered in adult healthy women when their daily alcohol intake exceeds 20g. Therefore for women drinking 2 glasses of beer, 2 small glasses of white wine, or 2 tall glasses of red wine per day exposes them to the risk of alcoholic liver disease. Chronic hepatitis C virus infection: Hepatitis C virus and alcohol go hand in hand and can significantly aggravate the progression of liver disease. In people with hepatitis C virus infection, even moderate amounts of alcohol, about 20-50 g of alcohol intake per day, significantly increase the incidence of cirrhosis and liver cancer. In addition patients with hepatitis C combined with alcoholic liver disease will develop decompensated liver dysfunction at an earlier age and have a poor overall prognosis. This is why patients with hepatitis C are advised to abstain from alcohol strictly.
