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.

This is called physiological jaundice. It is usually noticeable when the baby is 2 to 4 days old . Most of the time, it does not cause problems and goes away within 2 weeks. Two types of jaundice may occur in newborns who are breastfed.

What is the cause of physiological jaundice?

Physiologic jaundice is caused by a combination of increased bilirubin production secondary to accelerated destruction of erythrocytes , decreased excretory capacity secondary to low levels of ligandin in hepatocytes, and low activity of the bilirubin-conjugating enzyme uridine diphosphoglucuronyltransferase (UDPGT).

What may be the cause of neonatal physiological jaundice of the hepatic type?

In newborns, jaundice tends to develop because of two factors— the breakdown of fetal hemoglobin as it is replaced with adult hemoglobin and the relatively immature metabolic pathways of the liver , which are unable to conjugate and so excrete bilirubin as quickly as an adult.

What is the difference between physiological jaundice and pathological jaundice?

birth almost every newborn has a total serum bili- rubin (TSB) level that exceeds 1 mg/dL (17 mol/L), the upper limit of normal for an adult, and 2 of every 3 newborns are jaundiced to the clinician’s eye , this type of transient bilirubinemia has been called “physiologic jaundice.” When TSB levels exceed a certain ...

Is 16 a high bilirubin level?

Typically, bilirubin levels fall somewhere between 0.3 and 1.2 milligrams per deciliter (mg/dL). Anything above 1.2 mg/dL is usually considered high . The condition of having high bilirubin levels is called hyperbilirubinemia.

How is physiological jaundice diagnosed?

In most cases, a bilirubinometer is used to check for jaundice in babies. Blood tests are usually only necessary if your baby developed jaundice within 24 hours of birth or the reading is particularly high. The level of bilirubin detected in your baby’s blood is used to decide whether any treatment is needed.

Does jaundice cause brain damage?

When severe jaundice goes untreated for too long, it can cause brain damage and a condition called kernicterus. Early diagnosis and treatment of jaundice can prevent kernicterus.
