This is an iatroX educational summary of named Canada sources, not an official guideline. It does not replace the complete source documents, local policy, specialist advice or clinical judgement. Alberta is used as an explicit Canadian implementation example, not as a national rule. Verify the equivalent pathway, formulary and escalation route in the patient’s province or territory.

Alberta source: bounded use

Primary Care Pathway: NAFLD (Non-Alcoholic Fatty Liver Disease) supplies a Canadian implementation example for this summary. It must not be presented as the rule outside Alberta.

Source-attributed clinical priorities

  • Identify metabolic risk and exclude important alcohol, viral, autoimmune, medication and other causes of steatotic liver disease.
  • Use a validated first-line fibrosis assessment and refer indeterminate or high-risk results for specialist testing.
  • Treat cardiometabolic risk and support sustainable weight-related care; routine ultrasound alone cannot stage fibrosis.
  • Use noninvasive fibrosis risk, not the amount of steatosis on ultrasound, to prioritize referral.

Practical assessment and management workflow

1
Confirm metabolic risk, alcohol exposure, medicines and viral, autoimmune and inherited liver clues.
2
Calculate a validated first-line fibrosis score from current laboratory and clinical data.
3
Arrange elastography or hepatology assessment for indeterminate or high-risk results.
4
Treat weight-related and cardiometabolic risk and repeat fibrosis assessment at an interval matched to risk.

Safety, red flags and urgent escalation

  • Jaundice, coagulopathy, ascites, encephalopathy or gastrointestinal bleeding suggests advanced or acute liver disease.
  • Do not withhold indicated statin treatment solely because stable steatotic liver disease is present.
  • Avoid labeling metabolic steatosis until harmful alcohol use and other liver causes have been assessed.
