Excess bilirubin (hyperbilirubinemia) is the main cause of jaundice. Bilirubin, which is responsible for the yellow color of jaundice, is a normal part of the pigment released from the breakdown of "used" red blood cells.
What causes the jaundice to develop?
Jaundice is caused by too much bilirubin in the blood. This is known as hyperbilirubinaemia. Bilirubin is a yellow substance produced when red blood cells, which carry oxygen around the body, are broken down.
What diseases can cause jaundice?
- Infections of the liver from a virus (hepatitis A, hepatitis B, hepatitis C, hepatitis D, and hepatitis E) or a parasite.
- Use of certain drugs (such as an overdose of acetaminophen) or exposure to poisons.
What are the 3 types of jaundice?
Jaundice is the yellowing of the skin and sclera due to abnormally elevated levels of bilirubin in the blood. It can be characterized into three different categories including pre-hepatic, intra-hepatic, or post-hepatic.
What happens if jaundice is not treated?
When severe jaundice goes untreated for too long, it can cause a condition called kernicterus. Kernicterus is a type of brain damage that can result from high levels of bilirubin in a baby's blood. It can cause athetoid cerebral palsy and hearing loss.
When should I worry about jaundice?
Jaundice usually appears on the second or third day. If your baby is full-term and healthy, mild jaundice is nothing to worry about and will resolve by itself within a week or so. However, a premature or sick baby or a baby with very high levels of bilirubin will need close monitoring and medical treatments.
When does jaundice become dangerous?
Usually it is mild. The level of bilirubin that is harmful is around 20. Reaching a level this high is rare. High levels need to be treated with bili-lights.
What is jaundice and is it dangerous?
Jaundice is a condition in which the skin, whites of the eyes and mucous membranes turn yellow because of a high level of bilirubin, a yellow-orange bile pigment. Jaundice has many causes, including hepatitis, gallstones and tumors. In adults, jaundice usually doesn't need to be treated.23 Jul 2018
Jaundice is considered pathologic if it presents within the first 24 hours after birth, the total serum bilirubin level rises by more than 5 mg per dL (86 mol per L) per day or is higher than 17 mg per dL (290 mol per L), or an infant has signs and symptoms suggestive of serious illness.15 Feb 2002
Is hemolytic jaundice is Prehepatic?
Hemolytic jaundice, also known as prehepatic jaundice, is a type of jaundice arising from hemolysis or excessive destruction of red blood cells, when the byproduct bilirubin is not excreted by the hepatic cells quickly enough.
What happens if your bilirubin is high?
A high level of bilirubin in the blood is known as hyperbilirubinemia. High bilirubin levels can cause jaundice. Jaundice makes the skin and the whites of the eyes appear yellow, due to the brown and yellow bilirubin in the blood.24 Jul 2018
