Your liver works hard to keep your body productive and healthy. It stores energy and nutrients. It generates proteins and enzymes your body uses to function and ward off disease. It also rids your body of substances that can be dangerous- including alcohol.
The liver breaks down most of the alcohol a person consumes. But the process of breaking alcohol down generates toxins even more harmful than alcohol itself. These by-products damage liver cells, promote inflammation, and weaken the body's natural defenses. Eventually, these problems can disrupt the body's metabolism and impair the function of other organs.
Because the liver plays such a vital role in alcohol detoxification, it is especially vulnerable to damage from excessive alcohol.
