Newborn Jaundice: Causes, Bilirubin Testing and Treatment

Newborn jaundice is yellowing of the skin and eyes caused by bilirubin buildup. It is common, but high levels can be harmful and must be assessed according to the baby’s age in hours and risk factors.

Why jaundice occurs Bilirubin forms when red blood cells break down. A newborn’s liver may need several days to remove it efficiently. Prematurity, bruising, blood-group incompatibility, infection and feeding difficulties can increase levels.

How jaundice is checked Visual inspection alone is not enough. Hospitals may use a skin bilirubin meter, and a blood test confirms the level when needed. Results are interpreted using the baby’s exact age in hours, gestational age and risk factors.

Feeding and monitoring Frequent effective feeding helps the baby pass bilirubin in urine and stool. Breastfeeding usually continues, with lactation support if feeding is ineffective. Giving water or sugar water without medical advice is not appropriate.

Treatment Phototherapy uses special light to help the body eliminate bilirubin. Rarely, very high levels require more intensive treatment such as exchange transfusion. Treatment decisions are based on measured levels, not skin colour alone.

Urgent warning signs Jaundice during the first 24 hours, rapidly deepening yellow colour, poor feeding, difficulty waking, abnormal cry, fever, very few wet nappies, dark urine, pale stools or jaundice lasting longer than expected require prompt medical review.
