Why does TPN cause cholestasis?

Can TPN cause jaundice?
Cholestatic jaundice is the major complication of total parenteral nutrition (TPN) in infants and children.
Does TPN cause high bilirubin?
Disturbances of bilirubin metabolism such as jaundice or pigment gallstone formation occur during total parenteral nutrition (TPN). We have studied the effects of TPN on bile flow and bile acid secretion and on the hepatobiliary transport of bilirubin in rats.
Does TPN cause liver problems?
One of the major causes of morbidity and mortality in patients receiving long-term total parenteral nutrition (TPN) is liver disease. Early on, there is steatosis, which can evolve to steatohepatitis and eventually to cholestasis of varying severity.
How is TPN cholestasis treated?
Altering the type and amount of fat (lipid) that is administered and/or controlling the amount of glucose that is given in the TPN are common strategies used to help improve TPNAC. Other supportive measures for symptoms, and medications to slow the progression of liver failure may also be required.

Why is TPN hard on liver?
Fatty liver and liver failure Fatty liver is usually a more long-term complication of TPN, though over a long enough course it is fairly common. The pathogenesis is due to using linoleic acid (an omega-6 fatty acid component of soybean oil) as a major source of calories.
What are the long-term effects of TPN?
Bone disease (osteoporosis) TPN-induced liver damage or liver failure. TPN-induced liver failure occurs more often in children than adults. Some people who receive long-term TPN may develop social problems because TPN can severely limit their everyday activities.
