In the liver bilirubin is conjugated. This conjugation is brought about by certain enzymes. In Gilbert's syndrome these enzymes are absent which cause unconjugated hyperbilirubinemia).\nThe hyperbilirubinemia is usually precipitated by following conditions — Stress, Fatigue, Alcohol use, reduced calorie intake, intercurrent illness.\nThe hepatic biochemical tests are normal except for elevated bilirubin level (serum bilirubin concentration are usually < 3mg/dl)\nThe hepatic histology is normal\nThere is no association with cirrhosis.", 'role': 'assistant'}]
