Primary care physicians are at the forefront in screening for abnormal levels of liver enzymes and investigating the likely causes by obtaining a detailed history and physical examination, followed by appropriate laboratory and diagnostic workup. This review outlines common causes for the two main mechanisms of liver injury—cholestasis and hepatocellular insult—and explores the associated risk factors, methods of diagnosis, and management, with a focus on nonalcoholic fatty liver disease, one of the most often encountered causes of abnormal liver enzyme levels.
