Physiological Neonatal Jaundice
Physiological Neonatal jaundice occurs in 50-70% newborns. It
occurs in the first few days of life and generally disappears by 10th
day of life. A neonate is born with a haemoglobin of 18-19 gm%. In the first
few days of life the haemoglobin falls. In addition, the liver enzymes are
immature and unable to process the haemoglobin. Thus, excess unconjugated
bilirubin is formed leading to yellow discoloration of skin and sclera. The jaundice
is not serious and there are generally no complications.
According to Dr Mubina Agboatwalla –
Child Specialist in Karachi, in term neonates the bilirubin is 10mg% or
less. In prematures 12mg % or less. The baby is active and feeds well.
Physiologic jaundice sometimes runs in families. It cannot be prevented and resolves
by itself once the baby grows up and the enzymes become mature. Generally there
are no complications. Giving sunlight to the baby helps. Early morning and late
evening sun rays are effective.
