Understanding Newborn Jaundice - the Basics

What Is Newborn Jaundice?

Many babies are born with jaundice, a condition in which the skin and whites of the eyes are yellowish in color. In fact, about half of all newborns develop mild jaundice in the first few days. In premature babies, jaundice may start early and last longer than in full-term babies.

What Causes It?

Jaundice typically occurs because the liver is immature and does not function properly. In some cases, the liver produces more bilirubin than the newborn can get rid of. Bilirubin, which is yellowish in color, is produced when red blood cells are broken down and the oxygen-carrying pigment, called hemoglobin, is released into the baby's bloodstream.

Since many mothers and babies leave the hospital soon after delivery, jaundice may not appear until babies are at home.

It is important to contact your doctor if you notice signs of jaundice in your baby and to see the doctor that same day. While jaundice is usually very treatable, in rare cases it can cause brain damage.
