Fatty liver disease, also known as hepatic steatosis, is a condition characterized by the accumulation of fat in the liver. This excess fat can lead to inflammation and liver damage, potentially progressing to more severe conditions such as non-alcoholic fatty liver disease (NAFLD) or non-alcoholic steatohepatitis (NASH). Risk factors for fatty liver disease include obesity, diabetes, high cholesterol, and excessive alcohol consumption. Treatment typically involves lifestyle changes such as weight loss, dietary modifications, and increased physical activity, although more severe cases may require medical intervention. Fatty liver disease is a common and growing health concern worldwide, and research in this area focuses on understanding the underlying causes, improving diagnosis and treatment options, and reducing the prevalence and impact of the disease.
