Dr Long is passionate to improve overall healthcare of children and newborns.

Parenting is not easy, especially for new parents. Whether you are raising a newborn or a growing child, parents need to tackle many challenges.

Many choose to follow traditional methods passed down from their parents. Others join a maternal care group and adopt methods from other mothers based on experience. While people recommend these practices out of good intentions, these practices can cause some misconceptions and unintentional harm to your children.

Parents should heed the advice of a paediatrician. UCSI Hospital’s paediatrician Dr Long Wai Lup, who has 12 years of medical experience, was admitted as a paediatrician at the Royal College of Pediatrics and Child Health (MRCPHC) in 2019.

Here are his advices to parents when facing the following situations.

A baby could contract jaundice due to the deposition of a yellow pigment called bilirubin in the tissues. When the bilirubin exceeds a certain level, jaundice becomes visible to the observer.

It depends on the type and severity of jaundice. The unconjugated bilirubin may penetrate the brain cells. However, jaundice can lead to progressive brain damage, mental retardation, and death if there is no medical intervention.

Depending on the bilirubin level, phototherapy may be the go-to treatment. Your baby may need additional intravenous fluid therapy if he or she appears dehydrated. Regular monitoring of bilirubin level will be done from time to time.
