When a person consumes alcohol it is broken down by the liver. During this process many extremely harmful substances like acetaldehyde are generated that harm the liver more than the alcohol that is ingested. The damage caused by these substances leads to inflammation of the liver, formation of scars, reduction in the supply of oxygen through blood and over all liver damage. This makes it essential to drink within limits and ensure that you are not getting addicted to consuming alcohol. Alcohol consumption also damages other organs of the body and is very harmful to the rest of the body too in addition to the liver.
