Neonatal Jaundice: Normal vs Dangerous — A Parent's Guide
By Dashvanth Healthcare Medical Team · Reviewed by our specialists · East Delhi
Understanding Newborn Jaundice
Jaundice (yellow skin/eye discolouration from bilirubin accumulation) affects 60–80% of full-term and 80–90% of premature newborns. Most is harmless and transient. However, very high bilirubin levels can cause brain damage (kernicterus) — making recognition and timely treatment critical.
Physiological vs Pathological Jaundice
| Feature | Physiological (Normal) | Pathological (Concern) |
|---|---|---|
| Onset | Day 2–3 of life | Within 24 hours of birth |
| Duration | Resolves by Day 7–14 | Persists >2 weeks |
| Extent | Face/chest only | Palms, soles involved |
| Bilirubin | Below treatment threshold | Above age-specific threshold |
Treatment
- Phototherapy (blue light): Standard treatment. Light converts bilirubin into water-soluble form excreted in urine. Safe and effective
- Exchange transfusion: For very high levels not responding to phototherapy — replaces baby's blood to rapidly reduce bilirubin
- Frequent feeding: Promotes bilirubin excretion through stool
When to Return to Hospital Immediately
- Jaundice appears before 24 hours of age
- Rapid spread to palms and soles
- Baby very sleepy, not waking to feed, high-pitched cry
- Jaundice persisting beyond 3 weeks (may indicate liver disease — "neonatal cholestasis")
Does breastfeeding cause jaundice?
Breastfeeding jaundice (inadequate feeding causing dehydration) and breast milk jaundice (different mechanism, benign) both exist. Neither is a reason to stop breastfeeding — improve feeding frequency and consult your paediatrician.
