It is possible to recover from mild alcohol-induced liver damage after quitting drinking, but for non-alcohol-induced liver damage and severe liver damage, liver function may not be fully restored. Alcohol has a damaging effect on liver cells, and the liver can repair some of the damage itself after quitting drinking. For mild alcohol-induced liver injury, liver function can be restored. When alcoholic liver injury progresses to the extent of alcoholic liver fibrosis and alcoholic cirrhosis, abstinence from alcohol cannot completely reverse it. For other causes of liver function injury, alcohol is an independent risk factor for liver injury, and removing the alcohol factor alone is not enough. In addition to alcohol cessation, the cause of the disease should be treated Viral hepatitis should receive antiviral treatment, while fatty liver should be treated with weight control and a healthy diet. If the liver damage is already very severe, with cirrhosis, liver cancer, etc., it is very difficult for liver function to recover after quitting alcohol.
