First, it is necessary to determine whether the fatty liver is alcoholic or non-alcoholic. If it is non-alcoholic fatty liver with elevated transaminases, lifestyle interventions should be implemented first. Weight loss and exercise can treat fat-associated fatty liver. Generally, it is necessary to control the intake of calories and fats, especially saturated fatty acids, maintain an ideal weight, and exercise sufficiently and consistently. Similarly, if there is a significant increase in blood lipids, lipid-lowering drugs can also be used. Additionally, some liver-protective drugs can be incorporated into treatment. If it is alcoholic fatty liver, abstaining from alcohol is a key treatment, as well as appropriate nutritional support. For long-term alcoholics, since alcohol replaces the calories provided by food, there is generally an insufficient intake of protein and vitamins. Therefore, a diet high in protein and low in fat should be provided, along with appropriate vitamin supplementation, and liver-protective drugs can also be used.
