Fatty liver disease is a condition where excess fat accumulates in the liver cells, causing inflammation, scarring, and impaired liver function. Fatty liver disease can be classified into two types: alcoholic fatty liver disease, which is caused by excessive alcohol consumption, and non-alcoholic fatty liver disease, which is caused by other factors such as obesity, diabetes, high cholesterol, or certain medications. NAFLD is more common and affects up to 25% of the global population, according to the World Health Organization.
