Jaundice is a common condition seen in newborns. It typically appears as a yellowing of the skin and eyes. This condition is caused by high levels of bilirubin in the baby’s blood. Bilirubin is a yellow substance produced when red blood cells break down. In most cases, newborn jaundice is harmless and resolves on its own. However, in some cases, it may require medical attention.
Causes of Newborn Jaundice
There are several reasons why jaundice occurs in newborns:
Immature Liver:
A newborn’s liver is often not fully developed. It may not efficiently process bilirubin, leading to its accumulation in the blood.
Breastfeeding Jaundice:
Sometimes, breastfeeding can contribute to jaundice. This is often due to the baby not getting enough breast milk, which can slow the removal of bilirubin.
Blood Type Incompatibility:
If the baby’s blood type is different from the mother’s, the mother’s antibodies may attack the baby’s red blood cells. This process increases bilirubin levels.
Premature Birth:
Babies born before 37 weeks have livers that are even less developed, increasing the risk of jaundice.
Bruising During Birth:
Some babies experience bruising during birth, which can cause more red blood cells to break down, raising bilirubin levels.
Symptoms of Newborn Jaundice
The primary symptom of jaundice is the yellowing of the skin and eyes. This yellow tint usually starts on the face and moves down the body. Other symptoms may include:
Dark Urine: The baby’s urine may be darker than usual.
Pale Stool: The baby’s stool may be pale or clay-colored.
Lethargy: The baby may seem unusually sleepy or difficult to wake.
Poor Feeding: The baby may have difficulty feeding or may not be interested in feeding.
Types of Jaundice in Newborns
Jaundice can be classified into several types, depending on its cause:
Physiological Jaundice:
This is the most common type and occurs due to the immature liver. It typically appears 2-4 days after birth and resolves within 1-2 weeks.
Pathological Jaundice:
This type is caused by underlying health issues, such as blood type incompatibility or liver problems. It appears within the first 24 hours after birth and requires immediate medical attention.
Breastfeeding Jaundice:
This occurs when a baby is not getting enough breast milk, leading to dehydration and a slower removal of bilirubin.
Breast Milk Jaundice:
This type appears later, around the second week of life. It is caused by substances in breast milk that can increase bilirubin levels. This form is typically harmless and resolves on its own.
Hemolytic Jaundice:
This occurs when there is excessive breakdown of red blood cells, often due to blood type incompatibility between the mother and baby.
Diagnosis of Newborn Jaundice
Healthcare providers diagnose jaundice through a combination of physical examination and blood tests:
Physical Examination:
The doctor will examine the baby’s skin and eyes for signs of yellowing. They may also use a device called a transcutaneous bilirubinometer, which measures bilirubin levels through the skin.
Blood Tests:
If jaundice is suspected, a blood test will be performed to measure the baby’s bilirubin levels. If the levels are high, additional tests may be needed to determine the cause.
Treatment of Newborn Jaundice
Treatment for newborn jaundice depends on the severity of the condition:
Phototherapy:
This is the most common treatment. The baby is placed under a special light that helps break down bilirubin in the skin. The light changes the bilirubin into a form that can be more easily excreted in urine and stool.
Exchange Transfusion:
In severe cases, the baby’s blood may need to be replaced with donor blood to rapidly reduce bilirubin levels.
Intravenous Immunoglobulin (IVIg):
If jaundice is due to blood type incompatibility, IVIg can be used to reduce the breakdown of red blood cells.
Adequate Feeding:
Ensuring that the baby is feeding well is crucial. Frequent feedings can help reduce bilirubin levels by encouraging regular bowel movements, which help excrete bilirubin.

Prevention of Newborn Jaundice
While it’s not always possible to prevent jaundice, certain steps can be taken to reduce the risk:
Early Feeding:
Start breastfeeding as soon as possible after birth. This helps ensure the baby is well-hydrated and promotes regular bowel movements.
Frequent Feeding:
Feed the baby often, at least 8-12 times in the first few days. This helps lower bilirubin levels by encouraging frequent bowel movements.
Monitor for Signs:
Keep a close watch on the baby’s skin and eyes for any signs of yellowing. If jaundice is noticed, seek medical advice promptly.
Follow-Up Visits:
Attend all postnatal check-ups. The healthcare provider will check for jaundice and other newborn health issues.
When to Seek Medical Attention
Although newborn jaundice is often harmless, certain signs indicate that immediate medical attention is needed:
Jaundice Appears in the First 24 Hours:
Jaundice that appears within the first day of life is more likely to be severe and needs urgent evaluation.
Jaundice Spreads:
If the jaundice spreads down the baby’s body or becomes more intense, it’s important to contact a healthcare provider.
Baby is Lethargic or Difficult to Wake:
Extreme sleepiness or difficulty waking the baby could indicate high bilirubin levels, which can affect the brain.
Poor Feeding:
If the baby is not feeding well, this could worsen jaundice, as the bilirubin may not be excreted efficiently.
Long-Term Outlook for Babies with Jaundice
In most cases, newborn jaundice resolves without any long-term effects. However, if left untreated, severe jaundice can lead to complications such as:
Kernicterus:
This is a rare but serious condition caused by very high levels of bilirubin. It can lead to permanent brain damage, hearing loss, and other neurological problems.
Developmental Issues:
In severe cases, untreated jaundice may result in developmental delays and motor skill problems.
With proper treatment and monitoring, most babies recover fully from jaundice with no lasting effects.
Conclusion
Jaundice is a common condition in newborns, caused by high levels of bilirubin in the blood. While it is usually harmless and resolves on its own, it’s important for parents and caregivers to be aware of the signs and symptoms. Early detection and treatment are key to preventing complications. By understanding the causes, symptoms, and treatment options for newborn jaundice, parents can ensure their baby remains healthy and well-cared for during the early days of life.
