Jaundice is a common condition in newborns. It leads to a yellowing of the skin and eyes. While it often appears harmless, understanding its causes is essential for parents. This article will explore the main causes of jaundice in infants. We will also discuss when to seek medical attention.
What Is Jaundice?
Jaundice occurs when there is too much bilirubin in the blood. Bilirubin is a yellow substance produced when red blood cells break down. In adults, the liver helps process bilirubin. However, in newborns, this process can be slower. This delay can cause bilirubin levels to rise, leading to jaundice.
Types of Jaundice
There are several types of jaundice in infants. The most common types include:
Physiological Jaundice: This is the most typical form. It usually appears on the second or third day after birth. Most healthy newborns experience this type as their bodies adjust to life outside the womb.
Pathological Jaundice: This type occurs within the first 24 hours of life. It can indicate a more serious condition, such as an infection or blood disorder.
Breastfeeding Jaundice: This can occur in breastfed infants. It usually happens when the baby does not receive enough milk. As a result, bilirubin levels can rise.
Breast Milk Jaundice: This type can develop after the first week of life. It is linked to substances in the mother’s breast milk that can affect bilirubin processing.
Causes of Jaundice
1. Immature Liver Function
A newborn’s liver is still developing. This immaturity can affect its ability to process bilirubin efficiently. Most babies outgrow this condition within a couple of weeks.
2. Blood Type Incompatibility
If a mother and baby have different blood types, it can lead to problems. For example, if a mother has type O blood and the baby has type A or B blood, the mother’s body may produce antibodies. These antibodies can attack the baby’s red blood cells, causing them to break down faster and increase bilirubin levels.
3. Hemolytic Diseases
Conditions like Rh disease or ABO incompatibility can lead to hemolytic disease. In this situation, the baby’s immune system destroys its own red blood cells. This rapid breakdown can cause jaundice.
4. Prematurity
Premature infants often have immature liver function. This increases their risk of developing jaundice. Additionally, they may have other health issues that contribute to jaundice.
5. Dehydration
If a newborn is not feeding well, dehydration can occur. This lack of fluids can lead to higher bilirubin levels. Ensuring the baby is properly hydrated through breastfeeding or formula feeding is crucial.
6. Infections
Infections can also lead to jaundice. Conditions such as sepsis can affect the liver’s ability to process bilirubin. If a baby shows signs of infection, such as fever or poor feeding, medical attention is necessary.
7. Genetic Disorders
Certain genetic disorders can affect how the body processes bilirubin. For example, conditions like Gilbert’s syndrome or Crigler-Najjar syndrome can cause jaundice. These disorders may require specialized medical management.
When to Seek Medical Attention
Parents should monitor their baby for signs of jaundice. If jaundice appears within the first 24 hours of life, it is crucial to seek medical attention. Additionally, if the jaundice worsens or does not improve, a doctor should evaluate the baby.
Signs to watch for include:
A yellowing that spreads from the face to the chest and abdomen.
Poor feeding or lethargy.
High-pitched crying or unusual behavior.
If any of these symptoms are present, it is essential to contact a healthcare provider.
Treatment Options
Most cases of jaundice resolve without treatment. However, if bilirubin levels are too high, treatment may be necessary. Common treatments include:
Phototherapy: This is the most common treatment for jaundice. The baby is placed under special lights that help break down bilirubin in the skin.
Exchange Transfusion: In severe cases, an exchange transfusion may be required. This procedure involves removing the baby’s blood and replacing it with donor blood to reduce bilirubin levels.
Hydration: Ensuring the baby is well-hydrated can help lower bilirubin levels. Breastfeeding or formula feeding should be encouraged.

Conclusion
Jaundice is a common condition in infants. While it is often harmless, understanding its causes is important. Parents should monitor their baby for signs of jaundice. If any concerns arise, seeking medical attention is essential. With proper care, most babies recover without complications.
In conclusion, jaundice is mainly caused by the immature liver function of newborns. Other causes include blood type incompatibility, dehydration, and infections. By being informed and vigilant, parents can help ensure their infant’s health and well-being.
