HISTORY
                  Review risk factors (alcohol abuse, viral hepatitis, family history of primary liver cancer, other
                  liver disease, or autoimmune disease).
                  Symptoms
                  –  Fatigue, malaise, weakness
                  –  Anorexia, weight loss (weight gain if ascites/edema)
                  –  Right upper abdominal pain
                  –  Bruising, bleeding, hematemesis, hematochezia, melena
                  –  Tea-colored urine, clay-colored stools
                  –  Edema, abdominal swelling/bloating, pruritus
                  –  Bruising, bleeding, hematemesis, hematochezia, melena
                  –  Absent/irregular menses, chronic anovulation
                  –  Diminished libido, erectile dysfunction
                  –  Night blindness

               PHYSICAL EXAM
               Physical exam may be normal until end-stage disease—many relate to manifestations of portal
               hypertension
                  Skin changes: spider angiomas, palmar erythema, jaundice, scleral icterus, ecchymoses, caput
                  medusa, hyperpigmentation, decreased body hair, facial telangiectasias
                  Hepatomegaly (small, fibrotic liver when end-stage disease)
                  Splenomegaly (if portal hypertension)
                  Abdominal fluid wave, shifting dullness (ascites)
                  Gynecomastia
                  Dupuytren contractures
                  Pretibial, presacral pitting edema, and clubbing (especially in hepatopulmonary syndrome)
                  Asterixis, mental status changes (hepatic encephalopathy)
                  Muscle wasting, weakness
                  Fetor hepaticus (in severe portosystemic shunting)

               DIFFERENTIAL DIAGNOSIS
               Steatohepatitis, other causes of portal hypertension (e.g., portal vein thrombosis, lymphoma);
               metastatic or multifocal cancer in the liver; vascular congestion (e.g., cardiac cirrhosis); acute
               alcoholic hepatitis

               DIAGNOSTIC TESTS & INTERPRETATION
               Initial Tests (lab, imaging)
                  Aspartate aminotransferase/alanine aminotransferase (AST/ALT): mildly elevated, typically
                  AST > ALT; enzymes may normalize as cirrhosis progresses.
                  Elevated alkaline phosphatase (ALP), γ-glutamyl transpeptidase (GGT), and total/direct
                  bilirubin
                  Anemia from hemolysis, folate deficiency, and/or splenomegaly
                  Thrombocytopenia (<110; 95% specific for cirrhosis)
                  Impaired synthetic liver function denoted by hypoalbuminemia, low cholesterol, prolonged
                  prothrombin time (PT), international normalized ratio (INR), and partial thromboplastin time
                  (PTT); coagulopathy of vitamin K–dependent clotting factors (II, VII, IX, X)
                  Progressive cirrhosis indicated by hyperammonemia, elevated blood urea nitrogen (BUN),
