What Causes Jaundice in Babies: A Comprehensive Guide
Introduction
Hi readers,
Jaundice is a common condition in newborns that causes their skin and eyes to turn yellow. It’s caused by a buildup of bilirubin, a yellow pigment that’s produced when red blood cells break down. While jaundice is usually harmless and goes away on its own, it can sometimes be a sign of a more serious underlying medical condition.
In this article, we’ll delve into the various causes of jaundice in babies, its symptoms, and when to seek medical attention. We’ll also provide tips on helping your baby manage jaundice effectively.
Causes of Jaundice in Babies
Physiological Jaundice
This is the most common type of jaundice in newborns. It occurs because a baby’s liver is still immature and can’t break down bilirubin efficiently. Physiological jaundice typically appears within the first few days of life and peaks around 3-5 days. It usually goes away on its own within 2-3 weeks.
Breast Milk Jaundice
Some babies develop jaundice when they’re breastfed. This is because breast milk contains beta-glucuronidase, an enzyme that can slow down the breakdown of bilirubin. Breast milk jaundice usually appears around 3-4 days after birth and can last for up to 2-3 months.
Cholestasis
Cholestasis is a condition that blocks the flow of bile, the fluid that helps digest fats. This can lead to a buildup of bilirubin in the bloodstream. Cholestasis can be caused by a variety of factors, including infections, metabolic disorders, and structural abnormalities in the liver or bile ducts.
Other Causes
Other less common causes of jaundice in babies include:
- Hemolytic Jaundice: This occurs when red blood cells are broken down faster than usual, leading to a buildup of bilirubin. It can be caused by blood type incompatibilities, infections, or genetic disorders.
- Crigler-Najjar Syndrome: This is a rare genetic disorder that affects the enzyme that breaks down bilirubin. It can lead to severe jaundice that can cause brain damage if not treated.
- Gilbert’s Syndrome: This is a mild genetic disorder that affects the way bilirubin is processed by the liver. It typically causes only mild jaundice that does not require treatment.
Symptoms of Jaundice in Babies
The primary symptom of jaundice is yellowing of the skin and eyes. Other symptoms can include:
- Yellowing of the mucous membranes and tongue
- Dark yellow or orange urine
- Pale or clay-colored stools
- Lethargy
- Poor feeding
- Irritability
When to Seek Medical Attention
Most cases of jaundice in babies are harmless and do not require treatment. However, it’s important to seek medical attention if your baby:
- Is less than 3 days old and has jaundice
- Has jaundice that lasts for more than 3 weeks
- Has jaundice that gets worse rapidly
- Has other symptoms, such as fever, vomiting, or lethargy
- Is breastfed and has jaundice that lasts for more than 2-3 months
How to Help Your Baby Manage Jaundice
If your baby has jaundice, there are a few things you can do to help manage it:
- Increase feedings: This helps increase the flow of bile and remove bilirubin from the body.
- Expose your baby to sunlight: Bilirubin breaks down when exposed to light, so exposing your baby to sunlight for short periods can help reduce jaundice.
- Use a phototherapy lamp: This is a special light that helps break down bilirubin. It’s typically used for babies with severe jaundice.
Table: Types of Jaundice in Babies
| Type of Jaundice | Cause | Symptoms | Treatment |
|---|---|---|---|
| Physiological Jaundice | Immature liver | Yellow skin and eyes | No treatment necessary |
| Breast Milk Jaundice | Beta-glucuronidase in breast milk | Yellow skin and eyes | Increase feedings |
| Cholestasis | Blocked bile flow | Yellow skin and eyes, dark urine, pale stools | May require medication or surgery |
| Hemolytic Jaundice | Fast red blood cell breakdown | Yellow skin and eyes, anemia | May require blood transfusion |
| Crigler-Najjar Syndrome | Genetic enzyme deficiency | Severe jaundice | May require phototherapy or liver transplant |
| Gilbert’s Syndrome | Mild genetic disorder | Mild jaundice | No treatment necessary |
Conclusion
Jaundice is a common condition in newborns that can have a variety of causes. While most cases are harmless and go away on their own, it’s important to be aware of the symptoms and seek medical attention if your baby’s jaundice is severe or persistent.
If you’re concerned about your baby’s jaundice, don’t hesitate to consult with your healthcare provider. They can help determine the cause of your baby’s jaundice and recommend the best course of treatment.

FAQ about Jaundice in Babies
What is jaundice?
Jaundice is a condition that causes a baby’s skin and whites of the eyes to turn yellow.
What causes jaundice in babies?
Jaundice is caused by a build-up of bilirubin, a yellow substance that is produced when red blood cells are broken down. In babies, bilirubin levels can be high because their liver is not yet fully developed and cannot break down bilirubin as quickly as adults.
Is jaundice common in babies?
Jaundice is very common in babies, affecting up to 80% of newborns. Most cases of jaundice are mild and go away on their own within a few weeks.
What are the symptoms of jaundice?
The most common symptom of jaundice is yellow skin and whites of the eyes. Other symptoms can include:
- Dark yellow urine
- Pale stools
- Fatigue
- Irritability
How is jaundice diagnosed?
Jaundice is diagnosed with a blood test that measures bilirubin levels.
How is jaundice treated?
Most cases of jaundice do not require treatment and will go away on their own. However, if bilirubin levels are high, treatment may be necessary. Treatment options include:
- Phototherapy: This involves exposing the baby to special lights that help break down bilirubin.
- Exchange transfusion: This involves removing some of the baby’s blood and replacing it with blood from a donor.
What are the complications of jaundice?
If jaundice is not treated, it can lead to complications such as:
- Kernicterus: This is a serious condition that can cause brain damage.
- Liver damage
- Death
How can I prevent jaundice in my baby?
There is no way to prevent jaundice in all babies. However, there are some things you can do to reduce the risk of jaundice, such as:
- Breastfeeding your baby frequently.
- Giving your baby formula that is low in bilirubin.
- Exposing your baby to sunlight for short periods of time.
When should I call the doctor?
You should call the doctor if your baby has any of the following symptoms:
- Jaundice that does not go away after 2 weeks
- Yellow skin or whites of the eyes that are getting darker
- Dark yellow urine
- Pale stools
- Fatigue
- Irritability
