Metabolic-associated fatty liver disease (MAFLD) is the main condition of altered liver enzymes worldwide. With a constant increase in liver hospitalizations, MAFLD is the second cause of cirrhosis and soon will be the first cause of liver transplantation. Early recognition of MAFLD and a personalized approach are essential to its treatment. This case study presents personalized management of a patient with MAFLD with advanced fibrosis and severe steatosis. The impact of silymarin use, concomitant treatment with diet, exercise, insulin sensitizers and antifibrotic agents, was evaluated.
