Introduction

Jaundice in newborns can look alarming—but most cases are treatable and temporary.

Jaundice is one of the most common conditions affecting newborn babies. It causes a yellowish tint in the skin and eyes, typically within the first week of life. While most cases are mild, understanding when and how to treat jaundice is key to your baby’s health.

What Is Newborn Jaundice?

It’s caused by excess bilirubin

Bilirubin is a yellow pigment produced during the breakdown of red blood cells. Newborns often produce more bilirubin than their livers can handle, leading to jaundice.

How Common Is It in Malaysia?

Very common—especially among breastfed babies

In Malaysia, up to 60% of full-term and 80% of premature babies may develop jaundice. It’s more noticeable in fair-skinned babies but can affect all newborns regardless of ethnicity.

Symptoms Parents Should Watch For

• Yellow skin or eyes (especially under natural light)

• Drowsiness or difficulty waking up for feeds

• Poor feeding

• Dark yellow urine

• Pale or clay-coloured stool

When Is Treatment Needed?

Not all jaundice needs treatment

Mild jaundice often clears up on its own within 1–2 weeks. However, treatment may be needed if:

• Jaundice appears within the first 24 hours of birth

• The bilirubin level is rising quickly

• The baby is premature or low birth weight

• The baby is feeding poorly or losing weight

Home Treatment: The Role of Sunlight

Natural and effective—but do it safely

Sunlight helps break down bilirubin through the skin. Here’s how to use it safely:

• Expose baby to early morning sunlight (before 10 a.m.)

• Duration: 10–15 minutes at a time, 2–3 times daily

• Dress baby in minimal clothing (diaper only)

• Avoid direct midday sunlight to prevent overheating or sunburn

Important: Always supervise the baby during sun exposure.

Hospital Treatment: Phototherapy Explained

When sunlight isn't enough

Phototherapy is the most common hospital treatment. Your baby will be placed under special blue lights that help break down bilirubin.

Types of phototherapy:

• Single-surface phototherapy (lights from above)

• Double-surface phototherapy (lights above and below)

• Fibre-optic phototherapy (blanket-type for mild cases)

Treatment usually lasts 1–2 days and is safe and effective. Babies may need eye protection and frequent feeding during therapy.

When to See a Doctor Immediately

Seek urgent care if:

• Baby is less than 24 hours old with signs of jaundice

• Yellowing spreads rapidly or becomes intense

• Baby is very sleepy, not feeding, or showing signs of dehydration

• You feel something isn’t right—always trust your instincts

Did You Know?

• Exclusive breastfeeding can sometimes increase the risk of jaundice, but it’s still encouraged with regular monitoring

• Jaundice usually starts from the face and moves downward

• Severe jaundice, if untreated, can lead to a rare but serious condition called kernicterus

Conclusion

Newborn jaundice is common and often harmless—but it’s important to know when to treat and when to seek help. Early sunlight exposure may help in mild cases, while phototherapy is highly effective for more serious cases. Always follow your doctor’s advice and don’t hesitate to get a bilirubin test if you’re unsure.

FAQs

1. Can I use indoor light for jaundice treatment?

No. Only specific phototherapy lights or natural sunlight are effective.

2. How fast does sunlight help reduce jaundice?

You may see mild improvement within 1–2 days with consistent exposure.

3. Is jaundice painful for babies?

No, but high bilirubin levels can lead to complications if left untreated.

4. Can I continue breastfeeding during treatment?

Yes, and it's encouraged to help flush out bilirubin.

5. What if my baby still has jaundice after 2 weeks?

See your doctor. Prolonged jaundice may indicate underlying issues.
