Risk for hepatic and extra-hepatic outcomes in nonalcoholic fatty liver disease from the symposium: Non-Alcoholic fatty liver disease (NAFLD).

J Intern Med 2021 Jun 12. Epub 2021 Jun 12.

Division of Diagnostics and Specialist Medicine, Department of Health, Medicine and Caring Sciences, Linköping University, Linköping, Sweden.

Non-alcoholic fatty liver disease (NAFLD) is defined by presence of steatosis in more than 5% of liver cells. The gold standard for diagnosis is liver biopsy, but this is seldom achieved due to costs and risk for side-effects, why the diagnosis is mostly made based on a combination of radiology and exclusion of other liver diseases. Disease severity staging can be non-invasively achieved with radiological exams such as elastography, or blood-based markers, that usually have lower sensitivity and specificity. Read More
