What is the cause of hyperbilirubinemia?
The predominant causes of conjugated hyperbilirubinemia are intrahepatic cholestasis and extrahepatic obstruction of the biliary tract, with the latter preventing bilirubin from moving into the intestines. Viruses, alcohol, and autoimmune disorders are the most common causes of hepatitis.
What is the pathophysiology of neonatal jaundice?
Pathogenesis of neonatal jaundice includes physiologic process of bilirubin accumulation or pathological mechanism. The pathological jaundice may be acquired or inherited. Acquired neonatal jaundice include Rh hemolytic disease, ABO incompatibility disease, and hemolytic disease due to G6PD enzyme deficiency.
What does hyperbilirubinemia do to the body?
Hyperbilirubinemia and Jaundice | Overview This is called hyperbilirubinemia. Because bilirubin has a pigment or coloring, it causes a yellowing of your baby’s skin and tissues. This is called jaundice. Depending on the cause of the hyperbilirubinemia, jaundice may appear at birth or at any time afterward.
What does hyperbilirubinemia mean?

What are the types of hyperbilirubinemia?
Hyperbilirubinemia
- Jaundice.
- Hemolysis.
- Kernicterus.
- Cholestasis.
- Neonates.
- Bilirubin.
- Prematurity.
How does hyperbilirubinemia affect the liver?
high bilirubin levels (hyperbilirubinemia) can cause a form of brain damage called kernicterus. Also, many disorders that cause jaundice, particularly severe liver disease, cause other symptoms or serious problems.
What causes hyperbilirubinemia in newborns?
Hyperbilirubinemia happens when there is too much bilirubin in your baby’s blood. Bilirubin is made by the breakdown of red blood cells. It’s hard for babies to get rid of bilirubin at first. It can build up in their blood, tissues, and fluids.
What are the symptoms of hyperbilirubinemia?
What are the symptoms of hyperbilirubinemia in a newborn?
- Yellowing of your baby’s skin and the whites of his or her eyes. This often starts on a baby’s face and moves down his or her body.
- Poor feeding.
- Lack of energy.
When and how does hyperbilirubinemia happen?
What are the most common causes of pathologic hyperbilirubinemia in neonates?
The most common causes of hemolytic jaundice include (a) Rh hemolytic disease, (b) ABO incompatibility and (c) Glucose-6-phosphate dehydrogenase (G-6-PD) deficiency and minor blood group incompatibility.
How do you manage hyperbilirubinemia?
Treatments to lower the level of bilirubin in your baby’s blood may include:
- Enhanced nutrition.
- Light therapy (phototherapy).
- Intravenous immunoglobulin (IVIg).
- Exchange transfusion.
How is hyperbilirubinemia treated in adults?
How is jaundice treated? Jaundice usually doesn’t require treatment in adults (it’s a more severe problem in infants). The causes and complications of jaundice can be treated. For instance, if itching is bothersome, it may be eased by cholestyramine (Questran®).
What causes indirect hyperbilirubinemia?
Common causes of higher indirect bilirubin include: Hemolytic anemia. This means your body is getting rid of too many red blood cells. Bleeding into the skin caused by injury.
