Fatty Liver (part 2): Clinical Approach and Treatment

Patients with fatty liver are almost always asymptomatic; aminotransferases are usually elevated two to five times the expected value and are an important cause of initial consultation. All images can show fatty liver, and liver biopsy remains the gold standard for diagnosis. In any patient, non-invasive tests are an excellent alternative to biopsy to determine the degree of liver fibrosis and establish the stage of fibrogenesis. Weight loss and exercise are the fundamental pillars of the indicated treatment for all patients with overweight or obesity; a weight loss between 5% and 10% and a diet with caloric restriction of 500-1000 kcal/day, low in saturated fat and rich in Mediterranean diet products such as fruit, fish, vegetables, nuts, olive oil, among others, are recommended. There are other treatments, such as pharmacological measures and endoscopic and surgical procedures.
