Fatty liver is a disease that indicates a metabolic disorder and is considered a type of digestive system disease, as well as a liver disease. In top-tier hospitals, there is generally a hepatology department where one can seek treatment at their outpatient clinic. In slightly less equipped county-level secondary hospitals or third-tier hospitals, which do not have a hepatology outpatient clinic, one can visit the gastroenterology outpatient clinic. Additionally, basic health clinics, which do not have a gastroenterology outpatient clinic, require visiting a general internal medicine outpatient clinic.
