Jaundice is a common condition in newborns, characterized by a yellowish tint to the skin and eyes. It occurs when there is too much bilirubin, a substance produced when the body breaks down red blood cells, in the blood. While jaundice in newborns can be concerning for parents, it’s usually temporary and resolves on its own or with treatment.
In this blog post, we’ll explore how long jaundice typically lasts in newborns, what causes it, the different types of jaundice, and what parents can do to manage the condition.
Understanding Jaundice in Newborns
Jaundice in newborns occurs when there is an excess of bilirubin in the baby’s bloodstream. Bilirubin is a yellow substance that the liver usually processes and removes from the body. However, in newborns, the liver may not be fully developed and efficient at processing bilirubin, leading to a build-up that causes the yellowish appearance of the skin and eyes.
This condition is most commonly seen in the first few days of life and is generally harmless. The term “neonatal jaundice” is used to refer to jaundice that occurs in newborns, and it affects around 60% of full-term babies and 80% of premature babies.
Common Symptoms of Jaundice in Newborns
The most noticeable symptom of jaundice is the yellowing of the skin and the whites of the eyes (sclera). The yellow color usually starts on the face and may spread to the chest, abdomen, arms, and legs as the bilirubin level increases.
Other signs of jaundice may include:
- Fatigue or difficulty feeding
- Dark yellow or orange urine
- Pale-colored stools
If you notice any of these signs in your newborn, it’s important to consult a pediatrician for a proper diagnosis and management plan.
What Causes Jaundice in Newborns?
Jaundice in newborns can be caused by several factors. Understanding the cause helps determine how long jaundice will last and if treatment is needed.
Physiological Jaundice
The most common cause of jaundice in newborns is called physiological jaundice, which occurs because the baby’s liver is immature and unable to process bilirubin efficiently. This is a normal process and is usually seen in healthy, full-term babies.
- When it starts: Physiological jaundice typically appears 2-3 days after birth.
- How long it lasts: It usually peaks between 3-5 days of life and then begins to decrease. In most cases, it resolves within 1-2 weeks.
Breastfeeding Jaundice
Some babies, especially those who are breastfed, can develop a mild form of jaundice known as breastfeeding jaundice. This is due to insufficient breast milk intake, which can lead to dehydration and a delay in the elimination of bilirubin.
- When it starts: Breastfeeding jaundice typically appears in the first few days of life.
- How long it lasts: With increased feeding and proper hydration, the jaundice usually resolves within a few days to a week.
Breast Milk Jaundice
This type of jaundice occurs when substances in the mother’s breast milk interfere with the breakdown of bilirubin in the baby’s liver. It is more common in exclusively breastfed babies.
- When it starts: Breast milk jaundice generally appears after the first week of life, usually around 5-7 days.
- How long it lasts: It can last 2-3 weeks, but in some cases, it can persist for several months. However, it is usually not harmful.
Hemolytic Jaundice
In some cases, jaundice may be caused by the destruction of red blood cells, a condition known as hemolytic jaundice. This can occur if the baby has blood group incompatibility with the mother, such as Rh incompatibility or ABO incompatibility.
- When it starts: Hemolytic jaundice can develop within the first 24 hours after birth.
- How long it lasts: This type of jaundice requires medical treatment and may last longer, depending on the severity.
Other Causes of Jaundice
There are other, less common causes of jaundice in newborns, including infections, liver diseases, and metabolic disorders. These causes are usually more serious and require immediate medical attention.
How Long Does Jaundice Last in Newborns?
The duration of jaundice in newborns depends on the cause and the baby’s overall health. Let’s break down how long jaundice can last for different types of jaundice:
Physiological Jaundice
- Duration: Typically lasts for 1-2 weeks.
- When to seek medical help: If the jaundice persists beyond 2-3 weeks or the baby shows signs of worsening, such as poor feeding, lethargy, or difficulty waking up, it’s important to consult a pediatrician.
Breastfeeding Jaundice
- Duration: Can last up to 1 week, depending on how well the baby feeds.
When to seek medical help: If breastfeeding jaundice persists longer than 1 week or if the baby is not gaining weight properly, medical intervention may be necessary.
Breast Milk Jaundice
- Duration: Can last for 2-3 weeks, and in rare cases, up to 3 months.
When to seek medical help: If the jaundice is severe or lasts longer than expected, the pediatrician may assess the need for further evaluation.
Hemolytic Jaundice
- Duration: This type of jaundice can last for a longer period, depending on the severity of the hemolysis.
- When to seek medical help: Hemolytic jaundice requires medical management, such as phototherapy or blood transfusions, depending on the bilirubin levels.
Treatment for Jaundice in Newborns
In most cases, jaundice in newborns resolves on its own without the need for extensive treatment. However, there are a few treatment options your pediatrician may recommend, depending on the severity of the condition.
Phototherapy (Light Therapy)
One of the most common treatments for moderate to severe jaundice is phototherapy. This involves exposing the baby’s skin to special blue lights, which help break down bilirubin and speed up its elimination from the body.
- How it works: The light helps the bilirubin to convert into a form that can be excreted more easily.
- Duration: The baby may undergo phototherapy for 1-3 days, depending on the bilirubin levels.
Exchange Transfusion
In rare cases of severe jaundice, an exchange transfusion may be required. This involves replacing some of the baby’s blood with donor blood to reduce bilirubin levels quickly.
- When needed: This is typically only used in extreme cases where bilirubin levels are very high and pose a risk to the baby’s health.
Increased Feeding
For mild jaundice, increasing the frequency of feedings, whether breastfeeding or formula feeding, helps flush bilirubin out of the baby’s system through urine and stool. Ensuring the baby is well-hydrated can aid in this process.
Monitoring Jaundice at Home
Parents should monitor their newborn for signs of jaundice and report any changes to their pediatrician. Keeping track of feeding patterns, urine output, and the baby’s overall behavior can help determine if jaundice is resolving or if further medical intervention is needed.
When to Contact a Pediatrician
- If jaundice appears within the first 24 hours of birth.
- If the baby’s jaundice worsens or spreads beyond the face.
- If the baby is not feeding well, is excessively sleepy, or has a fever.
- If the baby’s stools are white or very pale, or if urine is dark.
Conclusion
Jaundice is a common and usually harmless condition in newborns. The duration of jaundice depends on the cause, but in most cases, it resolves within 1-2 weeks without the need for medical intervention. By understanding the different types of jaundice and knowing when to seek medical help, parents can manage the condition effectively and ensure the best care for their newborn.
If your baby has jaundice, it’s always best to consult with a pediatrician who can assess the situation and recommend the appropriate treatment if necessary.
