Common reasons for high ALT:

  • ALT is highly specific to liver injury (Fatty liver, Viral hepatitis, Autoimmune hepatitis, Liver cancer, Alcohol liver damage, Mononucleosis, Hemochromatosis).

    Muscle damage – strenuous exercise, trauma, myocardial infarction, congestive heart failure.

    Gallstones; Biliary disease; pancreatitis; both obesity and anorexia; rapid weight change; celiac disease; hemolysis.

    Many toxins and drugs can increase ALT, but most notable are: Paracetamol, NSAIDs, statins, phenytoin, allopurinol, and antibiotics, especially amoxicillin.
