What Is Newborn Jaundice?

Newborn Jaundice is a common condition that causes a yellowish discoloration of a baby’s skin and the whites of the eyes. It occurs when there is too much bilirubin in the baby’s blood—a yellow pigment produced during the normal breakdown of red blood cells.

In most cases, newborn jaundice is harmless and temporary. However, in rare cases, high bilirubin levels can pose a serious risk to the baby’s brain and overall health if not properly treated.

What Causes Newborn Jaundice?

The main cause is the baby’s immature liver, which may not be fully capable of processing and eliminating bilirubin efficiently. Other causes include:

1. Physiological Jaundice

• The most common type.
• Appears 2 to 4 days after birth and resolves within 2 weeks.

2. Breastfeeding Jaundice

• Occurs when a baby is not getting enough breast milk.
• Leads to dehydration and less bilirubin elimination.

3. Breast Milk Jaundice

• Caused by substances in breast milk that can slow down bilirubin processing.
• Appears after the first week and can last a month or more.

4. Blood Type Incompatibility

• If the mother and baby have different blood types, the baby’s red blood cells may be attacked and broken down faster (e.g., Rh or ABO incompatibility).

5. Prematurity

• Premature babies are more likely to develop jaundice due to liver immaturity.

6. Other Causes

• Infections
• Internal bleeding
• Enzyme deficiencies
• Liver disease

What Are the Symptoms of Newborn Jaundice?

• Yellowing of the skin and eyes (starts on the face and spreads downward)
• Poor feeding
• Lethargy
• Dark urine
• Pale stools
• High-pitched crying (in severe cases)

Symptoms usually appear within the first few days after birth.

How Is Newborn Jaundice Diagnosed?

1. Physical Examination

• Visual inspection for yellowing of the skin and eyes.

2. Bilirubin Test

• A blood test measures the level of bilirubin.
• A skin test using a device called a transcutaneous bilirubin meter may also be used.

3. Additional Tests (If Needed)

• Blood type and Coombs test to check for incompatibility
• Complete blood count (CBC)
• Tests for liver function or infections

How Is Newborn Jaundice Treated?

Most cases of jaundice resolve without treatment. However, if bilirubin levels are high, treatment is needed to prevent complications.

1. Phototherapy

• The baby is placed under special blue lights that help break down bilirubin through the skin.

2. Increased Feeding

• Frequent breastfeeding or formula feeding helps the baby pass more stool and reduce bilirubin.

3. Intravenous Fluids

• May be given if the baby is dehydrated or not feeding well.

4. Exchange Transfusion

• In severe cases, the baby’s blood is replaced with donor blood to quickly lower bilirubin levels.

What Is the Prognosis?

Most babies with jaundice recover completely with or without treatment. However, if untreated and bilirubin reaches dangerously high levels, it can lead to:

• Kernicterus: A rare but serious brain damage
• Hearing loss
• Cerebral palsy
• Developmental delays

With prompt diagnosis and treatment, these complications are almost always preventable.

Can Newborn Jaundice Be Prevented?

While not all cases can be prevented, you can reduce risk by:

• Ensuring frequent feeding in the first days after birth
• Monitoring high-risk babies (e.g., premature, blood type incompatibility)
• Getting early checkups within a few days of birth to detect rising bilirubin
