WGO Practice Guideline



NAFLD (Nonalcoholic Fatty Liver Disease and Nonalcoholic Steatohepatitis) is a condition defined by excessive fat accumulation in the form of triglycerides (steatosis) in the liver. A subgroup of NAFLD patients displays liver cell injury and inflammation in addition to excessive fat (steatohepatitis). The latter condition, designated NASH, is virtually indistinguishable histologically from alcoholic steatohepatitis (ASH).
