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.

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.
