In medicine, fatty liver, also called hepatic steatosis or liver steatosis is "lipid infiltration of the hepatic parenchymal cells resulting in a yellow-colored liver. The abnormal lipid accumulation is usually in the form of triglycerides, either as a single large droplet or multiple small droplets. Fatty liver is caused by an imbalance in the metabolism of fatty acids."[1]
Fatty liver includes steatohepatitis.
Etiology / cause
Fatty liver and steatohepatitis may be caused by the single-nucleotide polymorphisms rs2854116 (c.455T>C) and rs2854117 (c.482C>T) of apolipoprotein C-III which are also associated with insulin resistance and hypertriglyceridemia.[2]
Obesity may be the cause of cirrhosis in 12% of patients.[3][4]
Epidemiology/prevalence
Fatty liver and steatohepatitis are common, especially in diabetics and overweight people.[5]
Prognosis
NAFLD fibrosis score
