With liver disease, you may have other symptoms, such as jaundice, fatigue, weakness, nausea, and weight loss.

During a physical exam, your doctor can detect an enlarged liver on the right side of your abdomen. A variety of tests may also be needed to confirm the cause of an enlarged liver, including:

  • Blood tests to check for liver enzymes and other abnormalities related to liver disease
  • CT scan, magnetic resonance imaging (MRI), or ultrasound to view the liver

  • MRCP, a special MRI test to check the inside of the bile duct
  • Liver biopsy, an examination of a sample of liver tissue to check for cancer or a fatty liver
