Your liver helps your body digest food, store energy, and remove poisons. Fatty liver disease is a condition in which fat builds up in your liver. There are two main types:

• Nonalcoholic fatty liver disease (NAFLD)
• Alcoholic fatty liver disease, also called alcoholic steatohepatitis

Fatty Liver Disease is more common in people who

• Have type 2 diabetes and prediabetes
• Have obesity
• Are middle aged or older (although children can also get it)
• Are Hispanic, followed by non-Hispanic whites. It is less common in African Americans.
• Have high levels of fats in the blood, such as cholesterol and triglycerides
• Have high blood pressure
• Take certain drugs, such as corticosteroids and some cancer drugs
• Have certain metabolic disorders, including metabolic syndrome
• Have rapid weight loss
• Have certain infections, such as hepatitis C
• Have been exposed to some toxins

There are often no symptoms, making it difficult to diagnose fatty liver disease. To make a diagnosis, your doctor will use

• Your medical history
• A physical exam
• Various tests, including blood and imaging tests, and sometimes a biopsy
