Which statement describes physiologic jaundice duration?

• A. Physiologic jaundice is common and typically resolves within 1–2 weeks.
• B. It lasts for several months.
• C. It is a sign of infection requiring antibiotics.
• D. It is only seen in preterm infants.

Answer: (A)

Physiologic jaundice arises because a newborn’s liver is still maturing its ability to conjugate bilirubin. In a healthy term baby, bilirubin levels rise after birth, peak around day 2–3, and then decline as liver enzymes mature and bilirubin is excreted. Because of this natural maturation, it typically resolves within 1–2 weeks. The statement reflects this usual course for term infants. It isn’t months long, it isn’t a sign of infection needing antibiotics, and while preterm babies can have a longer course, the common pattern described is accurate for most term newborns. If jaundice appears very early, lasts much longer, or rises rapidly, that would warrant evaluation for other causes.
