Definition

Jaundice is a medical condition characterized by the yellowing of the skin and eyes due to elevated bilirubin levels in the blood. It often indicates underlying issues with the liver, bile ducts, or red blood cells.

2. In newborns, jaundice is common and usually resolves without treatment; however, severe cases may require phototherapy.
3. Biliary obstruction, caused by conditions like gallstones or tumors, can lead to jaundice by preventing bile excretion.
4. Hemolytic anemia, where red blood cells are destroyed faster than they can be produced, can cause jaundice due to increased bilirubin production.
5. Laboratory analysis for jaundice includes measuring serum bilirubin levels and liver function tests.
