Indeed, also using the old NAFLD definition, the disease is observed in up to 80% of obese people, 35% of whom progress to NASH, and in up to 20% of normal weight people, despite no evidence of excessive alcohol consumption. FLD is the most common cause of abnormal liver function tests in the United States. Fatty liver is more prevalent in Hispanic people than white, with black people having the lowest susceptibility.In the study of Children of the 90s, 2.5% born in 1991 and 1992 were found by ultrasound at the age of 18 to have non-alcoholic fatty liver disease; five years later transient elastography (fibroscan) found over 20% to have the fatty deposits on the liver, indicating non-alcoholic fatty liver disease; half of those were classified as severe. The scans also found that 2.4% had the liver scarring, which can lead to cirrhosis.After the lockdown of the COVID-19 pandemic, a study demonstrated that 48% of patients with liver steatosis gained weight, while 16% had a worsened steatosis grade. Weight gain was associated with poor adherence to the suggested diet, reduced levels of physical activity, and increased prevalence of PNPLA3 GG gene. PNPLA3 genes are already known risk factors for NAFLD. In animals
Fatty liver disease can occur in pets such as reptiles (particularly turtles) and birds as well as mammals like cats and dogs. The most common cause is overnutrition. A distinct sign in birds is a misshapen beak. Fatty livers can be induced via gavage in geese or ducks to produce foie gras.
