Obesity (not alcohol) is the #1 cause of liver disease in the U.S.

Nonalcoholic Fatty Liver Disease (NAFLD)

NAFLD causes excess fat to build up in the liver. Diet and digestive disorders are the main causes.

• NAFLD is the most common cause of liver disease worldwide.
• It is not caused by heavy alcohol use.
• 24% of U.S. adults are estimated to have NAFLD.
• NAFLD is present in up to 75% of overweight people.

Risk factors include:

1. being overweight/obesity
2. type 2 diabetes/insulin resistance
3. high cholesterol/triglyceride levels
4. one or more traits of metabolic syndrome (traits and medical conditions linked to overweight/obesity)
5. old age
