Newborn Jaundice Symptoms and Signs
What are the signs and symptoms of jaundice in newborns?
Jaundice usually appears first on the face and then moves to the chest, belly, arms, and legs as bilirubin levels get higher. The whites of the eyes can also look yellow. Jaundice can be harder to see in babies with darker skin color. The baby's doctor or nurse can test how much bilirubin is in the baby's blood.
Jaundice is the yellowish discoloration of the skin, mucous membranes and
the whites of the eyes (sclerae) caused by elevated levels of bilirubin in the
blood (hyperbilirubinemia). The term jaundice is derived from the French word
jaune, which means yellow.
Jaundice is not technically a disease, but
rather it is a visible sign of an underlying condition causing increased levels
of bilirubin in the blood.
Jaundice in newborns (neonatal jaundice)
Neonatal jaundice is the most common condition requiring medical evaluation
in a newborn. Though it is often a normal and transient physiologic
consequence of the newborn's immature liver, there are a variety of other
medical conditions which can cause severe neonatal jaundice. Jaundice in the
newborn must be carefully monitored, as excessively elevated levels of bilirubin
that go untreated for too long, can lead to permanent brain damage (a condition
What causes jaundice in newborns?
Jaundice is caused by the accumulation of bilirubin in the blood, typically
from an increased production of bilirubin or a decreased ability to metabolize
and excrete it. Bilirubin is formed when red blood cells break down and is
normally metabolized in the liver and excreted in urine and feces.
Neonatal jaundice can be caused by several different conditions, and it is
very commonly seen in newborns. The most common cause in newborns is physiologic
jaundice, which affects most newborns and is usually benign. However,
there are many other causes of neonatal jaundice that can be more serious, and
require further medical evaluation and intervention. A newborn that develops jaundice within the first 24 hours of life requires immediate medical attention. The following are some
of the causes of neonatal jaundice.
