Differential Diagnosis for Elevated Liver Enzymes (ALT, AST, GGT, ALK P)

Single Most Likely Diagnosis

  • Non-Alcoholic Fatty Liver Disease (NAFLD): This condition is increasingly common and often associated with obesity, diabetes, and metabolic syndrome, leading to elevated liver enzymes due to hepatic steatosis and inflammation.

Other Likely Diagnoses

  • Alcoholic Liver Disease: Chronic alcohol consumption can lead to liver damage, causing elevations in liver enzymes, particularly AST and GGT.
  • Viral Hepatitis (B and C): These infections can cause liver inflammation, leading to elevated liver enzymes.
  • Drug-Induced Liver Injury: Various medications and drugs can cause liver damage, resulting in elevated liver enzymes.
  • Biliary Obstruction: Obstruction of the bile ducts can cause elevations in ALK P and GGT, often due to gallstones or tumors.

Do Not Miss Diagnoses

  • Acute Hepatic Ischemia: Although rare, this condition can be fatal if not promptly recognized and treated. It may present with significantly elevated liver enzymes.
  • Wilson's Disease: A genetic disorder leading to copper accumulation in the liver, which can cause liver damage and elevated enzymes. Early diagnosis is crucial for treatment.
  • Autoimmune Hepatitis: An autoimmune condition that can cause liver inflammation and elevated liver enzymes. If missed, it can lead to cirrhosis and liver failure.

Rare Diagnoses

  • Alpha-1 Antitrypsin Deficiency: A genetic disorder that can cause liver disease and elevated liver enzymes due to the accumulation of abnormal alpha-1 antitrypsin protein.
  • Budd-Chiari Syndrome: A rare condition caused by thrombosis of the hepatic veins, leading to liver congestion, damage, and elevated liver enzymes.
  • Primary Biliary Cholangitis (PBC): An autoimmune disease of the bile ducts that can cause elevated ALK P and GGT, leading to liver damage and cirrhosis over time.
  • Primary Sclerosing Cholangitis (PSC): A chronic liver disease characterized by inflammation and scarring of the bile ducts, often presenting with elevated ALK P and GGT.
