  • Imaging : Usually presence of fat seen on ultrasound, CT scan or MRI.
  • Now a days Fibroscan can be used instead of liver biopsy.


  • Control the causes of fat accumulation.
  • Lifestyle modification including diet, regular exercise
  • Attempts to lose weight should be gradual approximately 1.5kg per week as rapid weight loss can be associated with worsening of liver function.
