Jaundice is a yellow discoloration of the skin, mucous
membranes, and the
whites of the eyes caused by increased amounts of bilirubin in the blood.
Jaundice is a sign of an underlying disease process.
Bilirubin is a by-product of the daily natural breakdown and destruction of
red blood cells in the body. The hemoglobin molecule that is released into the
blood by this process is split, with the heme portion undergoing a chemical
conversion to bilirubin. Normally, the liver metabolizes and excretes the
bilirubin in the form of bile. However, if there is a disruption in this normal
metabolism and/or production of bilirubin, jaundice may result.
What is the symptoms and signs of newborn jaundice?
As a baby's bilirubin levels rise, jaundice moves from the head to involve the arms, trunk, and finally the legs. If the bilirubin levels are very high, a baby will appear jaundiced below the knees and over the palms of his or her hands. One easy way to check for jaundice is to press a finger against your baby's skin, temporarily pushing the blood out of it. Normal skin will turn white when you do this, but jaundiced skin will stay yellow.
Older children and adults will appear jaundiced when the amount of bilirubin in their blood is above 2 milligrams per deciliter (mg/dL). Newborn babies will begin to appear jaundiced when they have more than 5 mg/dL of bilirubin in their blood. It is important to recognize and treat neonatal jaundice because high levels of bilirubin can cause permanent damage to a baby's brain. This brain damage is called kernicterus. Today, because of increased awareness and effective treatment of neonatal jaundice, kernicterus is extremely rare.
