Nonalcoholic Fatty Liver Disease (NAFLD) is a condition where excess fat builds up in the liver without alcohol consumption. It can lead to inflammation and damage, potentially progressing to more severe liver diseases, such as nonalcoholic steatohepatitis (NASH) and cirrhosis. NAFLD is often associated with obesity, diabetes, and high cholesterol levels. The exact cause of NAFLD is not fully understood, but it is linked to metabolic syndrome and lifestyle factors. Diagnosis typically involves blood tests, imaging studies, and sometimes a liver biopsy. Treatment focuses on lifestyle changes, including diet and exercise, to reduce liver fat and improve overall health.
