Nonalcoholic Fatty Liver Disease: What Does the Primary Care Physician Need to Know?

Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in the United States and is soon to be the leading cause of liver transplantation. Patients at the greatest risk are those with obesity and type 2 diabetes mellitus. In 2019 the American Diabetes Association guidelines called, for the first time, for clinicians to screen for steatohepatitis and fibrosis all patients with type 2 diabetes and liver steatosis or abnormal plasma aminotransferases. This requires primary care physicians to be aware of key aspects related to the diagnosis and treatment of NAFLD, as well as to when to refer to a specialist.
