, or hepatic steatosis, is the most common type of steatosis, constituting an accumulation of fat in the liver cells
. This condition is primarily caused by a diet overly-rich in lipids, or often due to chronic alcohol consumption. Metabolic disorders or certain drugs can also be responsible. Hepatic steatosis is often diagnosed by ultrasonography, which reveals the lipid deposits. This condition can progress to cirrhosis
of the liver, which progressively destroys the liver cells, impairing the liver's functions.
