What Causes Jaundice In Newborns?
Understanding Jaundice in Newborns
What Causes Jaundice In Newborns? Jaundice in newborns is a common issue that worries parents and caregivers. It shows as yellow skin and eyes due to too much bilirubin in the blood. Most newborns get jaundice at some point.
Definition of Jaundice
Jaundice makes a newborn’s skin and eyes look yellow. This happens because of bilirubin, made when old red blood cells break down. In newborns, the liver can’t handle bilirubin well right after birth. Knowing about jaundice in infants factors helps tell normal jaundice from serious problems.

Bilirubin overproduction in newborns comes from the fast breakdown of red blood cells right after birth. Babies have more red blood cell turnover than adults. This means more bilirubin in their blood. If the liver can’t process this bilirubin well, it builds up and causes jaundice.
Impaired Bilirubin Processing
Another reason for causes of neonatal jaundice is impaired bilirubin processing. Newborns’ livers might not work well at first. This can lead to bilirubin building up and causing jaundice. This issue usually goes away as the liver gets better at its job.
Delayed Bilirubin Excretion
Jaundice can also happen if bilirubin stays in the blood too long. This can be due to dehydration, not eating enough, or problems with the bile ducts. These issues slow down bilirubin leaving the body, keeping jaundice going.
| Cause | Description |
|---|---|
| Bilirubin Overproduction | Rapid breakdown of red blood cells releasing large amounts of bilirubin. |
| Impaired Bilirubin Processing | Underdeveloped liver function leading to insufficient bilirubin processing. |
| Delayed Bilirubin Excretion | Slow elimination of bilirubin due to various factors like dehydration or feeding issues. |
Newborn Liver Development and Jaundice
The liver in newborns is not fully grown at birth. This can make it hard for it to process bilirubin well. This is why newborn liver maturation is linked to jaundice in babies.
The liver is key in breaking down bilirubin, a waste from old red blood cells. But, newborns’ livers can’t do this job well yet. So, bilirubin builds up and causes jaundice. How well the liver changes bilirubin into something that can leave the body affects jaundice.
Experts in neonatal care stress the role of liver function in treating jaundice in newborns. Newborns’ livers are not ready to clear bilirubin fast. This makes jaundice last longer and be more severe.
Looking at liver function in newborns and older babies shows the challenge newborns face. Here’s a table that explains these differences:
| Age Group | Bilirubin Processing Efficiency | Jaundice Risk Level |
|---|---|---|
| Newborns (0-2 weeks) | Low | High |
| Infants (3 weeks – 1 year) | Moderate | Medium |
| Older Infants (1-2 years) | High | Low |
This table shows how liver development affects bilirubin processing. It also shows how this affects jaundice risk and treatment in babies.
Factors Leading to Jaundice in Newborns
It’s important to know why newborns get jaundice. Doctors and researchers have found many reasons. These include things like genes, blood types, and being born too soon.
Genetic Influences
Genes play a big part in jaundice in newborns. Some genes can cause enzyme problems. This makes it hard for babies to get rid of bilirubin.
Conditions like Gilbert’s syndrome and Crigler-Najjar syndrome can also cause high bilirubin levels. This leads to jaundice.
Blood Type Incompatibility
When a baby’s and mom’s blood types don’t match, it can cause jaundice. This happens when the mom’s body makes antibodies against the baby’s blood cells. These antibodies break down the baby’s red blood cells.
This leads to more bilirubin in the baby’s blood, causing jaundice.
Premature Birth
Babies born too soon often get jaundice. Their livers aren’t fully developed yet. They can’t process bilirubin well.
Also, preterm babies often have more red blood cells breaking down. This makes jaundice more likely.
| Factor | Description | Impact on Jaundice |
|---|---|---|
| Genetic Influences | Inherited genetic mutations leading to enzyme deficiencies | Impaired bilirubin processing and elevated bilirubin levels |
| Blood Type Incompatibility | Immune response due to ABO or Rh mismatch | Increased red blood cell breakdown, leading to higher bilirubin |
| Premature Birth | Underdeveloped liver function in preterm infants | Inefficient bilirubin processing, causing jaundice |
Common Baby Jaundice Triggers
Newborn jaundice is a common issue. It happens for many reasons. Knowing these reasons can help parents deal with it better.
Breastfeeding Jaundice
Breastfeeding related jaundice is one big reason. It happens when breastfeeding issues mean the baby doesn’t drink enough milk. This is often in the first week after birth.
It’s key to breastfeed right and feed often. Experts suggest more feedings and better latching. Studies say breastfeeding help is vital to stop and treat this jaundice.
Hemolytic Disease
Hemolytic disease in newborns is another big cause of jaundice. It happens when the baby’s and mom’s blood types don’t match. This makes the baby’s red blood cells break down.
This raises bilirubin levels and causes jaundice. Catching this early is crucial. Babies at risk need close checks and might need special treatments like light therapy or blood transfusions.
| Trigger | Description | Management Recommendations |
|---|---|---|
| Breastfeeding Related Jaundice | Occurs due to inadequate milk intake | Increase feeding frequency, improve latching techniques |
| Hemolytic Disease in Newborns | Caused by blood type incompatibility leading to red blood cell breakdown | Early detection, monitoring, phototherapy, or blood transfusions |
Medical Conditions Associated with Jaundice in Infants
Jaundice in infants can be linked to many medical conditions. These conditions play a big role in why jaundice happens. It’s important to know about them for early diagnosis and treatment.
Hypothyroidism
One condition linked to jaundice is hypothyroidism in newborns. This means the thyroid gland doesn’t make enough thyroid hormones. It slows down the body’s process of getting rid of bilirubin, leading to jaundice.
Doctors can spot this early through tests. Giving the baby thyroid hormones helps fix the issue.
Infections
Infections are a big reason for jaundice in babies. Things like urinary tract infections and sepsis can make jaundice worse. These infections can hurt the liver or break down red blood cells, raising bilirubin levels.
It’s key to catch and treat these infections fast to help the baby.
Enzyme Deficiencies
Some babies have enzyme shortages that can cause jaundice. For example, a lack of glucose-6-phosphate dehydrogenase (G6PD) can lead to breaking down red blood cells. This makes jaundice more likely. What Causes Jaundice In Newborns?
Babies with G6PD deficiency need to avoid things that can trigger jaundice. Regular checks and avoiding triggers are important. What Causes Jaundice In Newborns?
What Causes Jaundice In Newborns?
Jaundice in newborns has many causes. These include different conditions and how the body works. Knowing about these is key to treating it right.
Bilirubin overproduction is a big cause. This happens when newborns have a lot of red blood cells that break down. This leads to too much bilirubin, causing jaundice. The liver also has to process bilirubin well. In newborns, their livers are still growing. This can make it hard for them to break down bilirubin.
Delayed bilirubin excretion is another factor. This can be because of genes, blood types not matching, or being born too soon. These things make it hard for newborns to get rid of bilirubin, leading to more jaundice.
Conditions like hypothyroidism, infections, and enzyme deficiencies also cause jaundice. They mess with how bilirubin moves through the body. Plus, breastfeeding issues and certain diseases can make bilirubin levels go up in newborns.
Understanding jaundice in newborns means looking at many things. These include both the baby’s health and their genes. All these things help decide if a baby will get jaundice and how bad it will be.
| Factors | Details |
|---|---|
| Bilirubin Overproduction | High red blood cell turnover increases bilirubin levels. |
| Impaired Bilirubin Processing | Newborn livers are less efficient at breaking down bilirubin. |
| Delayed Bilirubin Excretion | Genetic factors, blood type incompatibility, and premature birth can delay bilirubin clearance. |
| Associated Medical Conditions | Conditions like hypothyroidism, infections, and enzyme deficiencies can interfere with bilirubin metabolism. |
| Common Triggers | Breastfeeding issues and hemolytic disease can elevate bilirubin levels. |

FAQ
What causes jaundice in newborns?
Jaundice in newborns happens when there's too much bilirubin. This is a yellow pigment made when red blood cells break down. Newborns' livers are still growing and can't get rid of bilirubin well, so it builds up.
What are the signs and symptoms of jaundice in infants?
Jaundice makes the skin and the whites of the eyes look yellow. It starts on the face and goes down to the chest, belly, legs, and eyes. Babies might feel tired, eat less, and cry a lot.
What are the primary causes of neonatal jaundice?
The main causes are too much bilirubin, not enough processing, and slow excretion. Too much bilirubin can come from certain diseases. Not processing it well might be due to genetic issues. And slow excretion is often because the liver is still growing.
