Nonalcoholic Fatty Liver Disease (NAFLD)


Have you been told you have fatty liver or non-alcoholic fatty liver disease (NAFLD)? If so, what does one do about it? First let’s define NAFLD. It is a condition in which excess fat builds up in the liver. This is not caused by alcohol use. About 25% of the worldwide population is affected by this condition. It is especially common in the western developed countries. About 10% of children between the ages of 2-19 are affected with NAFLD. There usually are no symptoms of NAFLD unless it has progressed to non-alcoholic steatophepatitis (NASH). This happens when the liver is inflamed can causes right upper abdominal pain and swelling. In most cases, NAFLD has no symptoms and is normally detected by routine blood tests.

Risk Factors of NAFLD

Overweight /Obesity (especially concentrated adiposity around the abdomen area)
Type 2 Diabetes, Prediabetes or Insulin Resistance
Metabolic syndrome (insulin resistance, high blood pressure, elevated cholesterol)
High blood pressure
Elevated cholesterol– especially elevated triglycerides
Diets that are high in fructose– commonly used to sweeten food and drinks.
certain medications such as corticosteroids

Diagnosis of NAFLD

physical examination
medical history
blood tests to check liver enzymes (alanine aminotransferase, aspartate aminotransferase)
imaging (ultrasound, CT scan, MRI scan)
liver biopsy

Prevention of NAFLD
