Fatty liver disease, also known as hepatic steatosis, is a prevalent yet often asymptomatic condition characterized by the accumulation of fat in liver cells. This buildup occurs when the liver processes more fat than it can metabolize or export, leading to fat deposits in the organ. Non-alcoholic fatty liver disease (NAFLD) is the most common form, associated with obesity, sedentary lifestyle, and poor dietary habits. If left untreated, NAFLD can progress to non-alcoholic steatohepatitis (NASH), causing inflammation, liver scarring, and potential liver failure. Alcohol abuse can also cause alcoholic fatty liver disease. Early detection, lifestyle changes, and medical intervention are crucial to managing fatty liver disease and preventing severe complications.
