How Common is Jaundice in Newborns?

Jaundice is a prevalent condition that affects a significant number of newborns in the UK and globally. It is characterised by a yellowing of the skin and the whites of the eyes, which occurs due to a high level of bilirubin - a yellow pigment produced during the normal breakdown of red blood cells. While jaundice can be alarming to new parents, it is generally a common and typically mild condition in newborns.

In the UK, it is estimated that around 60% of full-term newborns and 80% of preterm infants develop jaundice in the first week of life. The condition is more common in preterm babies due to their livers being less developed, which makes it more difficult for them to process bilirubin efficiently. For most babies, jaundice will appear around the second or third day after birth and usually resolves on its own by the time they are about two weeks old.

Physiological jaundice, which is the most common form, occurs because a newborn’s liver is not yet mature enough to clear bilirubin from the bloodstream quickly. This type typically appears during the first three days of life and peaks at around the fourth day before gradually decreasing without any intervention. While physiological jaundice is often harmless, healthcare professionals monitor bilirubin levels to ensure they do not rise to dangerous levels that could lead to complications, such as kernicterus, a rare but serious condition that can cause brain damage.

There are several risk factors that can increase the likelihood of a newborn developing jaundice, including prematurity, a sibling who previously had jaundice, bruising during birth, and having certain ethnic backgrounds, with higher incidence noted among East Asian and Mediterranean descents. Breastfeeding jaundice is also noted, which can occur in breastfed infants if they are not getting enough milk, leading to dehydration and increased bilirubin levels.

In the UK, the NHS provides guidelines for monitoring and managing neonatal jaundice. Midwives and paediatricians routinely check newborns for signs of jaundice in the first few days post-birth. If elevated bilirubin levels are detected, treatment options such as phototherapy, where the baby is placed under a special light that helps break down bilirubin in the skin, may be used.

Overall, while jaundice is very common in newborns, it is usually a benign and manageable condition. Early monitoring and intervention are key to preventing any potential complications. Parents are encouraged to seek medical advice if they notice prolonged yellowing of their baby’s skin or eyes, or other symptoms such as poor feeding or lethargy.

Frequently Asked Questions

What is jaundice in newborns?

Jaundice in newborns is a condition characterized by yellowing of the skin and eyes due to elevated levels of bilirubin in the baby's blood.

How common is jaundice in newborns?

Jaundice is very common in newborns, affecting about 60% of full-term infants and 80% of premature infants.

Why is jaundice common in newborns?

Newborns often have immature liver function, which can lead to temporary high levels of bilirubin in the blood, causing jaundice.

When does jaundice usually appear in newborns?

Jaundice typically appears within the first 2 to 4 days of life and often resolves without treatment within 1 to 2 weeks for full-term infants.

What causes jaundice in newborns?

Jaundice is usually caused by the baby’s liver not being mature enough to efficiently process bilirubin, a byproduct of the breakdown of red blood cells.

Is jaundice in newborns a serious condition?

Mild jaundice is often harmless and resolves on its own. However, severe jaundice can be dangerous and requires medical intervention.

How is newborn jaundice diagnosed?

Jaundice is diagnosed by a physical examination and measuring bilirubin levels in the baby’s blood.

What are the symptoms of jaundice in newborns?

The primary symptom is a yellow tint to the skin and eyes. Severe jaundice may cause extreme lethargy or poor feeding.

How long does jaundice last in newborns?

In most cases, jaundice will resolve within 1 to 2 weeks in full-term infants and slightly longer in premature infants.

Can jaundice in newborns be prevented?

While jaundice itself may not be entirely preventable, ensuring adequate feeding can help lower the risk by promoting regular bowel movements to eliminate bilirubin.

Are there treatments for newborn jaundice?

Yes, treatments include phototherapy, increased feeding to promote hydration and bowel movements, and in severe cases, blood transfusions.

What is phototherapy for jaundice in newborns?

Phototherapy is a treatment that uses light to break down bilirubin in the skin, making it easier for the baby's body to eliminate.

When should I be concerned about my newborn’s jaundice?

You should contact a healthcare provider if the jaundice appears within the first 24 hours, the baby is extremely lethargic, or if the jaundice persists beyond two weeks.

Do all newborns get screened for jaundice?

Most hospitals screen newborns for jaundice before discharge using a bilirubin test to ensure early detection and treatment if necessary.

Can jaundice in newborns lead to other health issues?

Severe, untreated jaundice can lead to complications such as kernicterus, a type of brain damage caused by excess bilirubin.

Is jaundice more common in breastfed babies?

Some breastfed babies may have a slightly higher risk of jaundice due to factors related to breastfeeding, but it is usually a temporary and manageable condition.

Should I stop breastfeeding if my baby has jaundice?

No, breastfeeding should usually continue. Increased feeding can help resolve jaundice by increasing bowel movements which help to remove bilirubin.

Does jaundice affect newborns differently depending on ethnicity?

Some studies suggest that babies of East Asian, Mediterranean, or Native American descent may have a higher risk, but jaundice can affect babies of all ethnicities.

Can jaundice recur in a newborn?

Jaundice may recur if underlying conditions persist, but in most healthy newborns, once resolved, it typically does not recur.

What is the role of bilirubin in jaundice?

Bilirubin is a yellow pigment released during the normal breakdown of red blood cells. In newborns, excess bilirubin can lead to jaundice if not efficiently processed by the liver.
