2. gilbert’s syndrome
What is the mechanism of pre-hepatic jaundice?
decreased glucuronidation so increased unconjugated bilirubin
What is the mechanism of hepatocellular jaundice?
conjugated bilirubin leaks out of hepatocytes and loose in urine so dark urine
What is the mechanism of post-hepatic jaundice?
conjugated bilirubin leaks out hepatocytes giving dark urine
not getting to large bowel have decreased stercobilinogen so pale stool
