Jaundice is a condition that causes a yellowish tint in a newborn’s skin and eyes. It happens because of high levels of a substance called bilirubin, which is produced when the body breaks down old red blood cells. Most of the time, jaundice is a common condition seen in newborns, but it raises an important question: does every newborn have jaundice?
In this article, we will explore the causes of jaundice, how often it occurs, and whether it affects all newborns. We will also discuss how to recognize jaundice in babies, the different types of jaundice, and when it is important to seek medical help. Understanding jaundice and its causes will help parents make informed decisions about their baby’s health.
What is Jaundice?
Jaundice occurs when there is too much bilirubin in the blood. Bilirubin is a yellow substance that forms when the body breaks down old or damaged red blood cells. Normally, the liver processes bilirubin and removes it from the body. However, in newborns, especially in the first few days of life, the liver is still developing and may not be able to handle the bilirubin as effectively as an adult’s liver.
When bilirubin builds up in the bloodstream, it is deposited in the skin and eyes, giving the baby a yellowish appearance. Jaundice is common in newborns, but not every baby will develop it. In most cases, it is mild and goes away on its own, but in some cases, jaundice can be a sign of a more serious condition.
How Common is Jaundice in Newborns?
It is estimated that around 60% of full-term newborns and 80% of premature newborns develop jaundice to some extent. This means that while jaundice is common, it does not affect every newborn. The condition is more likely to appear in the first few days of life, typically between the second and fifth day after birth.
Jaundice is usually harmless in most newborns and resolves without treatment. However, in some cases, it may be more severe or linked to other medical conditions that require medical attention.
Types of Jaundice in Newborns
Not all jaundice is the same. There are different types of jaundice, and each one has different causes. Here are the main types of jaundice that affect newborns:
1. Physiological Jaundice
Physiological jaundice is the most common type of jaundice in newborns. It is considered a normal part of the newborn’s development. It occurs because the baby’s liver is still maturing and may not be able to remove bilirubin from the blood as efficiently as an adult’s liver. This type of jaundice usually appears two to three days after birth and typically resolves on its own within two weeks.
Most babies with physiological jaundice will not need treatment, as the condition will improve as the liver becomes more efficient at processing bilirubin. However, parents should monitor the baby’s condition to ensure that the jaundice does not worsen.
2. Breastfeeding Jaundice
Breastfeeding jaundice occurs in some babies who are breastfed. It happens when the baby is not getting enough milk, either because the mother’s milk is not coming in fully or because the baby is having trouble latching on and feeding properly. When the baby does not get enough milk, they do not produce enough urine and stool, which are the main ways the body gets rid of bilirubin.
Breastfeeding jaundice usually appears in the first few days of life and can be improved by increasing the baby’s feeding frequency. In most cases, breastfeeding jaundice resolves once the baby is getting enough milk and is feeding well. If the jaundice does not improve, the baby may need to be seen by a pediatrician to ensure that breastfeeding is going well.
3. Pathological Jaundice
Pathological jaundice is less common but more serious than physiological jaundice. It usually appears within the first 24 hours after birth and may last longer than two weeks. This type of jaundice can be caused by a number of underlying medical conditions, such as blood group incompatibility, infections, or liver diseases.
Pathological jaundice requires medical attention to determine the underlying cause and provide appropriate treatment. The bilirubin levels may need to be carefully monitored, and treatments such as phototherapy (light therapy) or a blood transfusion may be necessary to prevent complications.
4. Hemolytic Jaundice
Hemolytic jaundice occurs when there is an increased breakdown of red blood cells in the baby’s body. This can happen due to blood group incompatibility between the mother and the baby, such as when the mother is Rh-negative and the baby is Rh-positive. In these cases, the mother’s immune system may attack the baby’s red blood cells, leading to more bilirubin being produced and causing jaundice.
Hemolytic jaundice can also be caused by other conditions, such as hereditary disorders or infections. Treatment may involve phototherapy or, in more severe cases, a blood transfusion.
5. Jaundice Due to Liver Disease
In rare cases, jaundice in newborns can be caused by liver disease or other serious conditions that affect the liver’s ability to process bilirubin. Conditions such as biliary atresia, a condition where the bile ducts are blocked, can cause jaundice to persist for a longer period of time.
If jaundice is caused by a liver disease, the baby will require special medical treatment to manage the condition. Early diagnosis and treatment are crucial to prevent complications.
How to Recognize Jaundice in Newborns
Jaundice is most easily recognized by the yellowing of the baby’s skin and the whites of their eyes. However, the yellowing may not always be noticeable in the first few days of life, especially in babies with lighter skin tones. To check for jaundice, gently press the baby’s skin, and if it appears yellow when the pressure is released, this may be a sign of jaundice.
In addition to the yellowing of the skin, jaundice may cause the baby to be more fussy than usual. Parents may notice that the baby is not feeding well, is sleeping more than usual, or has dark urine and pale stools.
It is important for parents to monitor their baby’s condition and seek medical advice if they notice any of the following signs:
- Jaundice appears within the first 24 hours of life (this may indicate a more serious cause of jaundice).
- The jaundice gets worse or does not improve after a few days.
- The baby is not feeding well or is very sleepy.
- The baby has signs of dehydration, such as fewer wet diapers.
- The baby has a high-pitched cry, which may indicate discomfort.
Treatment for Jaundice in Newborns
For most newborns with jaundice, no treatment is necessary. The jaundice will usually resolve on its own within a few days to two weeks. However, in some cases, medical treatment may be required, especially if the jaundice is caused by a more serious condition.
1. Phototherapy (Light Therapy)
Phototherapy is a common treatment for jaundice in newborns. The baby is placed under special blue lights that help break down the bilirubin in the skin. Phototherapy is often used when bilirubin levels are high enough to pose a risk of complications.
The baby may be placed in a special incubator or under a light with only their diaper on. Phototherapy helps to reduce bilirubin levels quickly and is very effective in treating jaundice. The baby’s bilirubin levels are monitored regularly during treatment to ensure that they are decreasing.
2. Exchange Blood Transfusion
In rare cases of severe jaundice, a baby may need an exchange blood transfusion. This procedure involves replacing some of the baby’s blood with donor blood to remove excess bilirubin. This is usually only done when bilirubin levels are dangerously high and other treatments, such as phototherapy, have not been effective.
3. Treating Underlying Conditions
If jaundice is caused by an underlying condition, such as an infection or liver disease, the baby will need specific treatment for that condition. The doctor will work with the parents to address the cause of the jaundice and provide appropriate medical care.
When to Seek Medical Help
While most cases of jaundice in newborns are mild and resolve without treatment, there are situations when parents should seek medical help. If jaundice appears within the first 24 hours after birth, it may indicate a more serious condition that requires immediate medical attention.
Additionally, parents should contact a doctor if:
- The jaundice worsens over time.
- The baby has trouble feeding or shows signs of dehydration.
- The baby’s bilirubin levels are very high and the doctor recommends treatment.
- The baby seems unusually tired or irritable.
Conclusion
Not every newborn will have jaundice, but it is a very common condition in the first days of life. Most cases of jaundice are mild and go away on their own, especially if they are caused by physiological jaundice. However, in some cases, jaundice can be a sign of a more serious condition that requires medical treatment.
Parents should monitor their baby’s health and seek medical advice if they are concerned about jaundice. Early detection and treatment are important to ensure the baby’s well-being. With proper care and monitoring, most babies with jaundice will recover fully and without complications.
