Liver steatosis, also known as fatty liver disease, is a condition characterized by the accumulation of fat in the liver cells. This can be caused by a variety of factors such as obesity, alcohol consumption, insulin resistance, and certain medications. Liver steatosis can lead to inflammation, fibrosis, and potentially progress to more serious conditions such as nonalcoholic fatty liver disease (NAFLD) or nonalcoholic steatohepatitis (NASH). Research in this area focuses on understanding the underlying mechanisms of liver steatosis, developing diagnostic tools, and identifying effective treatments to prevent the progression of the disease.
