Infant jaundice is a common condition that affects many newborns, often causing concern among parents and caregivers. Characterized by a yellowing of the skin and the whites of the eyes, jaundice occurs when there is an excess of bilirubin in the baby’s blood.
Understanding the connection between bilirubin and infant jaundice is essential for recognizing the condition and seeking appropriate care. This blog post explores bilirubin production, how it leads to jaundice in infants, and our infant jaundice management products used to manage and treat the condition effectively.
What Is Bilirubin?
Bilirubin is a yellow-orange pigment that is a natural byproduct of the body’s process of breaking down old red blood cells. In adults and older children, the liver efficiently processes bilirubin, converting it into a form that can be excreted through bile and eliminated via the intestines. This process helps maintain normal levels of bilirubin in the bloodstream, preventing any adverse effects.
In newborns, however, the situation is different. Babies are born with higher levels of red blood cells, which have a shorter lifespan than those in adults. As these cells break down, they produce more bilirubin than the newborn liver can handle. Additionally, the enzymes required to process bilirubin may not be fully developed in infants, leading to an accumulation of bilirubin in the blood – a condition known as hyperbilirubinemia.
How Bilirubin Leads to Infant Jaundice
The excess bilirubin in a newborn’s bloodstream begins to deposit in the skin and the sclera (the whites of the eyes), causing them to appear yellow – a hallmark sign of jaundice. This yellowing typically becomes noticeable when bilirubin levels exceed 5 milligrams per deciliter (mg/dL). The progression of jaundice often follows a head-to-toe pattern, starting from the face and moving downwards as bilirubin levels rise.
Several factors contribute to the development of jaundice in infants. Premature babies are at a higher risk because their livers are even less mature, making them less efficient at processing bilirubin. Breastfeeding can also play a role; while it offers numerous benefits, some breastfed babies may develop jaundice due to inadequate intake leading to dehydration and decreased bowel movements, which slows the excretion of bilirubin.
Blood type incompatibilities between the mother and baby, such as Rh or ABO incompatibility, can accelerate the breakdown of red blood cells, increasing bilirubin production. Other contributing factors include bruising during birth, internal bleeding, or genetic disorders that affect red blood cell stability.
Types of Infant Jaundice
Understanding the different types of infant jaundice can help in identifying the cause and determining the appropriate treatment. The most common type is physiological jaundice, which appears in most newborns as a natural response to their developing bodies and usually resolves without intervention within two weeks.
Breastfeeding jaundice occurs when a baby is not getting enough breast milk, leading to dehydration and reduced bilirubin excretion. Increasing the frequency of feedings can often alleviate this condition. Breast milk jaundice is a less common form that arises from substances in the breast milk that inhibit bilirubin processing; it typically appears after the first week of life and can persist for several weeks.
Hemolytic jaundice results from blood type incompatibility or genetic conditions that cause rapid red blood cell breakdown. This type often requires medical intervention due to the higher risk of severe hyperbilirubinemia. Jaundice from inadequate liver function, seen in conditions like Gilbert’s syndrome or Crigler-Najjar syndrome, is due to inherited enzyme deficiencies affecting bilirubin processing.
Diagnosing Infant Jaundice
Early detection of jaundice is crucial to prevent potential complications. Healthcare providers typically examine newborns for signs of jaundice before hospital discharge and during follow-up visits. Visual assessments involve checking for yellowing of the skin and eyes under good lighting conditions.
A transcutaneous bilirubinometer may be used to estimate bilirubin levels by measuring the skin’s reflectance. For more accurate results, especially if high levels are suspected, a blood test is performed. This test measures the total serum bilirubin (TSB) levels, helping determine the severity of jaundice and the need for treatment.
In cases where underlying conditions are suspected, additional tests may be ordered. These can include blood type testing for incompatibilities, complete blood counts, and tests for red blood cell enzyme deficiencies or genetic disorders.
Treatment and Management
The treatment of infant jaundice aims to reduce bilirubin levels in the bloods’]
tream, preventing the pigment from reaching levels that could cause complications. Phototherapy is the most common and effective infant jaundice treatment method. In phototherapy, the baby is placed under special blue-spectrum lights, seen with our BiliCocoon Kangaroo Care Fiber Optic Phototherapy System, that alter the structure of bilirubin molecules in the skin, making them easier for the body to eliminate without further processing by the liver.
During phototherapy, the infant’s eyes are protected using a product such as our WeeSpecs & WeeSpecs Supreme Infant Eye Protection, to prevent damage, and care is taken to maintain body temperature and hydration levels. Jaundice management products such as the Bili Pod Phototherapy Swaddle keep infants comfortable and reduce stress during treatment. Treatment continues until bilirubin levels drop to a safe range, which may take a few hours to several days.
Increasing feeding frequency can also help manage mild jaundice by promoting regular bowel movements, which aids in bilirubin excretion. For breastfeeding jaundice, lactation consultants can provide support to ensure the baby is feeding effectively.
Potential Complications
While most cases of infant jaundice are mild and resolve without lasting effects, severe hyperbilirubinemia can lead to serious complications if not promptly treated. Kernicterus is a rare but severe form of brain damage that occurs when very high levels of unconjugated bilirubin cross the blood-brain barrier and deposit in brain tissues.
Kernicterus can result in long-term neurological problems, including cerebral palsy, hearing loss, vision problems, and intellectual disabilities. Early recognition and treatment of high bilirubin levels are critical to prevent these irreversible outcomes.
Preventing Infant Jaundice
While not all cases of jaundice can be prevented, certain measures can reduce the risk or severity. Ensuring that the baby feeds adequately after birth is one of the most effective strategies. Frequent feedings stimulate regular bowel movements, which help eliminate bilirubin from the body.
For mothers with known blood type incompatibilities, medical teams can monitor and manage potential hemolytic jaundice proactively. In some cases, administering Rh immunoglobulin (Rhogam) during pregnancy can prevent the mother’s immune system from attacking the baby’s red blood cells.
Regular check-ups in the days following birth allow healthcare providers to monitor bilirubin levels and intervene promptly if necessary. Educating parents on the signs of jaundice empowers them to seek medical attention when needed.

The connection between bilirubin and infant jaundice is a fundamental aspect of neonatal care. Understanding how bilirubin metabolism affects newborns sheds light on why jaundice is common and often benign. However, awareness of the potential risks associated with high bilirubin levels underscores the importance of monitoring and, when necessary, treating this condition.
By recognizing the signs of jaundice, understanding its causes, and knowing when to seek medical intervention, parents and caregivers can play a vital role in ensuring the health and well-being of their infants. Advances in phototherapy treatment have made managing jaundice more effective, reducing the likelihood of complications and promoting positive outcomes for newborns worldwide.
