Chronic alcohol abuse can harm the body's organ systems in a variety of ways. The liver, which is mainly accountable for metabolizing alcohol, is frequently damaged by excessive or sustained alcohol consumption. There are three phases of liver damage associated with alcohol. After around 2 weeks of abstinence, the first condition, alcoholic fatty liver disease, can be entirely reversed. Alcoholic hepatitis is the second stage. If you quit drinking, moderate alcoholic hepatitis can be reversed, but a more severe case can be lifelong. Cirrhosis is the final stage, in which your liver is irreversibly scarred. Cirrhosis is irreversible, but quitting drinking can slow down the scarring process. The brain is yet another organ that can be severely harmed by long-term alcohol consumption, both intrinsically and extrinsically, as a result of dietary inadequacies, accidents, and liver disease. Some of the harm caused to the brain can be addressed by abstaining from alcohol, and some may be irreversible. After 1-5 months of quitting, most cognitive and motor functions will return to pre-drinking levels, and after 4-5 months of not consuming, most cognitive and motor functions will recover to the pre-drinking stage.
