What you should know about breast milk jaundice?
Watch out for what we call the “yellow flags” that signal an overreaction to jaundice in the breastfeeding baby. In most cases, it is not necessary to treat jaundice when bilirubin levels are less than 20 milligrams. Most jaundiced infants do not need supplements of water, sugar water or formula.
Why are some babies born with jaundice?
Is it advisable to give formula to newborn for jaundice?
Can breast feeding cause jaundice?
Jaundice is often still present when a mother first starts breastfeeding, and usually, the consistent supply of milk helps lower the baby's bilirubin levels. Sometimes, breastfed babies have difficulty getting rid of jaundice. This can lead to what's known as breastfeeding jaundice or breastmilk jaundice.
What enzyme in breast milk causes jaundice?
ß-glucuronidase is an enzyme naturally present in the body that deconjugates bilirubin in the intestinal brush border, leading to increased unconjugated bilirubin levels. [2] Studies have shown that the activity of this enzyme within formula milk is negligible, but it is considerable in human breast milk.
Is jaundice more common in breastfed babies?
Breastfeeding and Jaundice Physiologic jaundice occurs more frequently in breastfed than formula fed babies. It occurs, in particular, among babies who do not nurse frequently in the first days of life or are not breastfeeding well and who continue to lose weight.
How long does breastmilk jaundice last?
[3] Breast milk jaundice typically presents in the first or second week of life and usually spontaneously resolves even without discontinuation of breastfeeding. However, it can persist for 8-12 weeks of life before resolution.
What is the difference between physiological jaundice and breastfeeding jaundice?
Physiologic jaundice: occurs between 1 and 7 days of life and peaks at 3–5 days. Breastfeeding jaundice (BFJ): exaggerated physiologic jaundice associated with inadequate milk intake. Breast milk jaundice (BMJ): occurs between 1 and 12 weeks in thriving breast milk–fed infant.

Does Formula get rid of jaundice?
In breastfed babies, it is common for jaundice to last 1 month or occasionally longer. In formula-fed babies, most jaundice goes away by 2 weeks. Let your baby's doctor know if your baby has jaundice for more than 2 weeks if your baby is formula fed or longer than 4 weeks if your baby is primarily breastfed.
What color is jaundice poop?
It is the bilirubin associated with normal destruction of older red blood cells. This is called physiologic jaundice. The baby's urine is usually light yellow and the stool color is mustard yellow or darker. In some cases, the level of indirect bilirubin can go very high.
What causes galactosemia jaundice?
Classic galactosemia results from mutations in the galactose-1-phosphate uridyl transferase gene and causes infants to present with jaundice after initiation of lactose containing formulas. Jaundice associated with galactosemia is often thought to have a prominent direct fraction.
What causes bilirubin to be high in babies?
Newborns produce more bilirubin than adults do because of greater production and faster breakdown of red blood cells in the first few days of life. Normally, the liver filters bilirubin from the bloodstream and releases it into the intestinal tract.
What does unconjugated bilirubin do?
Some bilirubin is bound to a certain protein (albumin) in the blood. This type of bilirubin is called unconjugated, or indirect, bilirubin. In the liver, bilirubin is changed into a form that your body can get rid of. This is called conjugated bilirubin or direct bilirubin.
What causes newborn jaundice?
Jaundice is common in newborn babies because babies have a high number of red blood cells in their blood, which are broken down and replaced frequently. A newborn baby's liver is not fully developed, so it's less effective at processing the bilirubin and removing it from the blood.

Why does breast milk cause jaundice?
It happens within the first week of life due to the abnormal accumulation of bilirubin , causing a yellowish discoloration to the neonate's skin known as jaundice. This activity reviews the evaluation and treatment of breast milk jaundice and explains interprofessional team members' role in managing patients with this condition.
What are the factors that cause breast milk jaundice?
Some human breast milk factors that may be related to breast milk jaundice's etiology include pregnane-3a,20ß-diol, interleukin IL1ß, ß-glucuronidase, epidermal growth factor, and alpha-fetoprotein. [5] The presence of pregnane-3a,20ß-diol, is thought to inhibit bilirubin's conjugation, which in turn impede bilirubin excretion. ß-glucuronidase is an enzyme naturally present in the body that deconjugates bilirubin in the intestinal brush border, leading to increased serum reabsorption instead of excretion.[2] Studies have shown that this enzyme's activity within formula milk is negligible, but it is considerable in human breast milk.[6] Interleukine IL1ß is thought to have a cholestatic effect that leads to hyperbilirubinemia.[5] The epidermal growth factor is present in higher concentrations in human breast milk and strictly breastfed infants' serum. The reason is that this substance enhances intestinal resorption of bilirubin and reduces intestinal motility in the neonatal period, leading to increased unconjugated bilirubin levels.[ [2]The serum of babies with breast milk jaundice often has elevated levels of alpha-fetoprotein. The mechanism underlying this is not yet understood.
What is the gene that causes unconjugated hyperbilirubinemia?
Prolonged unconjugated hyperbilirubinemia associated with breast milk and mutations of the bilirubin uridine diphosphate- glucuronosyltransferase gene. [Pediatrics. 2000]
Why do babies have high bilirubin levels?
Before discussing the mechanism for breast milk jaundice, it is crucial to understand neonatal bilirubin metabolism and why neonates, in general, are affected by hyperbilirubinemia. Newborns have markedly increased bilirubin production compared to their adult counterparts secondary to a higher blood volume and hemoglobin concentration, a shorter red blood cell lifespan, and liver enzymes' physiological immaturity. These factors combined result in a relatively high production of unconjugated form, which is not water-soluble. Excrete bilirubin from the body further conversion of the unconjugated form to conjugated ( water-soluble) type is required. The conjugation process occurs within the hepatocyte by bilirubin uridine diphosphate glucuronosyltransferase (bilirubin-UGT) enzyme. UGT1A1 gene codes this enzyme production. Therefore those with genetic mutations in this gene are unable to conjugate bilirubin adequately. This enzyme is also significantly less active in neonates than adults, leading to less efficient conjugation. After conjugation and excretion from hepatocytes, the bilirubin passes to the small intestine where it gets converted to stercobilin by gut flora and subsequently excreted via the stool.
How long does breast milk jaundice last?
noted that some breastfed infants had unconjugated hyperbilirubinemia that persisted beyond the third week of life. [3] Breast milk jaundice typically presents in the first or second week of life and usually spontaneously resolves even without discontinuation of breastfeeding. However, it can persist for 8-12 weeks of life before resolution.[2] Infants with breast milk jaundice often have higher serum bilirubin peaks and slower decline, compared to the hyperbilirubinemia trend associated with other etiologies, leading to longer resolution time.[4] Pathological causes of unconjugated hyperbilirubinemia should be ruled out before a breast milk jaundice diagnosis can be made.
What is jaundice in neonates?
Jaundice, also known as hyperbilirubinemia, is a frequently encountered clinical problem in neonates. About 60-80% of all term or late-term, healthy newborns will develop some degree of hyperbilirubinemia.[1] The definition of neonatal hyperbilirubinemia has typically been total serum bilirubin (TSB) levels within the high-risk zone, or greater than the 95th percentile for age within the first six days of life.[1] When total serum bilirubin levels rise, a yellowish discoloration of the infant’s skin and sclera occurs and is referred to as jaundice. Neonatal hyperbilirubinemia has a higher frequency in breastfed infants compared to formula-fed infants.[2] The two common mechanisms for this are “breastfeeding jaundice” and “breast milk jaundice.”
How long does it take for a baby to be jaundiced?
Breast milk jaundice typically presents within the first two weeks of life in an otherwise healthy infant who is predominantly breastfed. These infants exhibit normal weight gain with the adequate production of urine and stools.[2]. A total serum bilirubin level above 1.5 mg/dL is considered elevated at this time, but most infants will not appear jaundiced unless the level is above 5 mg/dL. If the infant does appear jaundiced, this yellowish discoloration of their skin and/or sclera is typically first noted in the face and then proceeds to the trunk and extremities.
When does breast milk jaundice develop?
The symptoms of breast milk jaundice often develop after the first week of life. These may include:
How to diagnose jaundice in breast milk?
A diagnosis of breast milk jaundice may be made if the consultant determines that your infant is latching onto the breast well and getting enough milk. Your doctor will then use a blood test to confirm the diagnosis. This test will measure the amount of bilirubin in your baby’s blood. High levels of bilirubin indicate jaundice.
How long does it take for breast milk jaundice to go away?
Babies with breast milk jaundice usually recover with the right treatment and careful monitoring. The condition typically goes away after one or two weeks if the child’s liver becomes more efficient and they continue to consume adequate amounts of milk. In rare cases, jaundice may persist past the sixth week of life, even with proper treatment. This can indicate an underlying medical condition that requires more aggressive treatment.
Why do babies have yellow eyes?
When there’s too much bilirubin in the blood, it can settle in the skin. This causes the skin and eyes to appear yellow. Breast milk jaundice is a type of jaundice associated with breast-feeding. It typically occurs one week after birth.
Why does bilirubin fade?
Typically, the yellow discoloration caused by bilirubin fades on its own as the maturing liver breaks down the pigment. It’s passed from the body in the urine or stool. Doctors don’t know why jaundice occurs in infants who adapt well to breast-feeding.
How long does milk jaundice last?
Breast milk jaundice is a type of jaundice associated with breast-feeding. It typically occurs one week after birth. The condition can sometimes last up to 12 weeks, but it rarely causes complications in healthy, breast-fed infants. The exact cause of breast milk jaundice isn’t known.
How to treat jaundice in newborn?
This can help your infant pass the bilirubin in their stool or urine. Severe jaundice is often treated with phototherapy, either in the hospital or at home. During phototherapy , your baby is kept under a special light for one to two days.
Why do babies get jaundice while breastfeeding?
We know why babies get breastfeeding jaundice. It is generally from sub-optimal milk intake which causes bilirubin levels to rise. No one knows exactly what causes breast milk jaundice. Some believe it may be linked to a someone component of the breast milk, but there is no consensus.
Why is infant jaundice more common in breastfed babies?
Infant jaundice is more common in breastfed babies because their metabolisms tend to start a little slower. Babies on formula are less likely to get jaundice and when they do get jaundiced it tends to go away faster compared to breast fed babies. Treatment for Breastfeeding and Breast Milk Jaundice.
What causes yellowish skin on newborn?
Infant jaundice is a condition that occurs when a baby has elevated bilirubin levels, causing their skin and eyes to have a yellowish tint. Jaundice in newborns is extremely common, with 60% of full-term babies and 80% of preterm babies having the condition during the first week of life. In most cases, jaundice does not present any complications and resolves itself over time. Jaundice is often still present when a mother first starts breastfeeding, and usually, the consistent supply of milk helps lower the baby's bilirubin levels.
What is the cause of jaundice in infants?
Infant jaundice stems from excessive bilirubin in the blood. Bilirubin is a substance made during the normal breakdown of red blood cells and is passed through the liver before being excreted from the body. The primary symptoms of jaundice are yellowing of the skin and eyes.
What are the two types of jaundice?
There are two types of jaundice in breastfed babies: (1) breastfeeding jaundice; and (2) breast milk jaundice. They may sound similar, but they have different causes and treatment. 1) Breastfeeding Jaundice. Breastfeeding jaundice usually occurs in the first week of life while the baby and mother are in the early stages ...
Why do babies have jaundice?
There are several reasons as to why a baby is born with jaundice, including: The newborn has a higher rate of bilirubin production due to a shorter lifespan of red blood cells and higher red blood cell concentration.
When does jaundice occur in breast milk?
Breastfeeding jaundice usually occurs in the first week of life while the baby and mother are in the early stages of learning how to breastfeed. Breastfeeding jaundice is the result of the baby not receiving enough milk to lower their bilirubin levels. This causes the bilirubin to be reabsorbed into the intestines and keep ...
Why do babies have jaundice after breast feeding?
Breast milk jaundice is seen after the first week of life. It is likely caused by: Factors in a mother's milk that help a baby absorb bilirubin from the intestine. Factors that keep certain proteins in the baby's liver from breaking down bilirubin.
How often do you get breast milk jaundice?
Breastfeeding failure or breast-non-feeding jaundice may also occur when feedings are scheduled by the clock (such as, every 3 hours for 10 minutes) or when babies who show signs of hunger are given pacifiers. Breast milk jaundice may run in families.
What is it called when you can't feed your baby?
This kind of jaundice is different because it starts in the first few days of life. It is called "breastfeeding failure jaundice ," "breast-non-feeding jaundice," or even "starvation jaundice.". Babies who are born early (before 37 or 38 weeks) are not always able to feed well.
Why do my eyes turn yellow?
Jaundice is a condition that causes the skin and whites of the eyes to turn yellow. There are two common problems that may occur in newborns receiving breast milk.

The baby should recover fully with the right monitoring and treatment. The jaundice should go away by 12 weeks of life.
Why do they do jaundice tests?
These tests are done to be sure that there are no other, more dangerous causes of the jaundice.
How do you know if a baby is hungry?
Feed whenever baby is alert, sucking on the hands, and smacking the lips. This is how babies let you know they are hungry. If you wait until your baby cries, feeding will not go as well. Give babies unlimited time at each breast, as long as they are sucking and swallowing steadily.
What causes jaundice in breast milk?
Some factors in human breast milk that may be related to the etiology of breast milk jaundice include proteins and enzymes thought to inhibit the conjugation of bilirubin that allows for its excretion. ß-glucuronidase is an enzyme naturally present in the body that deconjugates bilirubin in the intestinal brush border, leading to increased unconjugated bilirubin levels.[2] Studies have shown that the activity of this enzyme within formula milk is negligible, but it is considerable in human breast milk.[4] Interleukin IL1ß e IL6 is thought to have a cholestatic effect that leads to hyperbilirubinemia.[5] The epidermal growth factor is present in higher concentrations in human breast milk and the serum of strictly breastfed infants.

What is infant jaundice?
Infant jaundice, also known as hyperbilirubinemia, is a frequently encountered clinical problem in neonates. Estimates are that between 60-80% of all term or late-term, healthy newborns exhibit physiologic jaundice with no cause found (idiopathic).[1] The definition of neonatal hyperbilirubinemia has typically been total serum bilirubin (TSB) levels within the high-risk zone, or greater than the 95th percentile for age within the first six days of life.[1] Jaundice within the first 24 hours could be pathological and must be reported to the health care provider. When total serum bilirubin levels rise, a yellowish discoloration of the infant’s skin and sclera occurs and is referred to as jaundice. Neonatal hyperbilirubinemia has a higher frequency in breastfed infants compared to formula-fed infants.[2] The two common mechanisms for this are “breastfeeding jaundice” and “breast milk jaundice.”
How to manage hyperbilirubinemia in infants?
In addition to the routine medical management of hyperbilirubinemia, which for breastmilk jaundice involves monitoring the jaundice without changes in the infant’s breastfeeding, nursing management includes providing education and support for the parents of infants with jaundice. Anything outside of normal can cause stress for new parents. In the rare cases where an infant needs to stop breastfeeding for 24 hours, nurses need to educate the mother on proper pumping procedure and safe storage of breastmilk. Infants who will continue breastfeeding should be encouraged to breastfeed every 2 to 3 hours until they learn to self-pace their own feedings. A sleepy jaundiced baby sometimes does not stay awake long enough for a good feeding, which can worsen hyperbilirubinemia. The mother may need breastfeeding assistance, and referral to a lactation consultant is a good option in areas where that is available. In addition, as bilirubin is excreted, the infant’s stools may become rather explosive. Reassure parents this is normal, and the more green that comes out in the stool, the less yellow will be in the baby’s skin. Education on infant bathing and appropriate diapering and skincare to prevent breakdown is important.
What causes hyperbilirubinemia in newborns?
The clinician will investigate other possible causes of hyperbilirubinemia if jaundice does not resolve by 12 weeks of age. Galactosemia and hypothyroidism have also been identified as causes of unconjugated hyperbilirubinemia and should be ruled out via standard newborn screening tests. [2][7][2]
How often do infants have milk jaundice?
The frequency of breast milk jaundice within the United States is thought to be 20-30% for neonates from 3 to 4 weeks of age whose feeding is predominantly via breastfeeding. About 30-40% of breastfed infants are expected to have bilirubin levels greater than or equal to 5 mg/dL, with about 2-4% of exclusively breastfed infants having bilirubin levels above 10 mg/dL in week 3 of life.[1] International studies in countries such as Turkey and Taiwan found that 20-28% of neonates had breast milk jaundice present at four weeks of age. Total serum bilirubin levels were also noted to be greater than or equal to 5 mg/dL in these cases.[6] The international frequency of breast milk jaundice is not extensively reported but is thought to be similar to the frequency in the United States. No reports exist demonstrating a gender predilection.
How long does milk jaundice last?
However, it can persist for 8-12 weeks of life before resolution.[2] Infants with breast milk jaundice often have higher peaks of serum bilirubin and an overall slower decline than infants without it, leading to longer resolution time.[3] Usually, pathologic causes of persistent, unconjugated hyperbilirubinemia are ruled out before a diagnosis of breast milk jaundice can be made.
When to notify the provider of jaundice?
Notify the provider if jaundice is visible in an infant less than 24 hours of age. While monitoring serum bilirubin levels, notify the provider if levels exceed 15mg/dL. If infant demonstrates behavioral change (lethargy or irritability, decreased urine output, decreased stool or other signs of possible dehydration, encourage the infant to feed more frequently, and notify the provider if the infant is more than 3 days old and has fewer than 6 wet diapers in 24 hours or experiences weight loss.
What Is Breast Milk Jaundice?
Another type of jaundice is breast milk jaundice, which occurs due to the constantly high bilirubin in babies who are healthy and well-fed. This occurs because your breast milk itself (instead of the feeding pattern) causes the increased bilirubin levels. Breast milk jaundice is associated with the inhibition of special proteins or enzymes, which increases the absorption of bilirubin from your baby’s gastrointestinal tract . Breast milk jaundice often presents much later (2 – 3 weeks after birth), and has a higher increase and much slower decline in bilirubin levels. If jaundice persists or bilirubin levels continuously rise, your doctor may recommend halting breastfeeding. This is the opposite of breastfeeding jaundice, where breastfeeding is further encouraged.

Pathophysiology
Characterized by a yellow discoloration of the eyes, skin, and urine.
Jaundice is not always related to an underlying condition. It may be caused by:
- Large bruises leading to high amounts of unconjugated bilirubin
- Fasting for long periods
- Medications
- Excess alcohol intake
Overview
Diagnosis
Causes
- Normally, bilirubin passes through the liver, which releases it into the intestinal tract. In newborns, however, the liver is often underdeveloped and may not be able to remove bilirubin from the blood. When theres too much bilirubin in the blood, it can settle in the skin. This causes the skin and eyes to appear yellow.
Treatment
- Breast milk jaundice is a type of jaundice associated with breast-feeding. It typically occurs one week after birth. The condition can sometimes last up to 12 weeks, but it rarely causes complications in healthy, breast-fed infants. Breast milk jaundice is rare, affecting less than 3 percent of infants. When it does occur, it usually doesnt cause any problems and eventually goe…
Prognosis
- Its important to note that breast milk jaundice isnt related to breast-feeding jaundice. Breast-feeding jaundice only develops in newborns that struggle with breast-feeding and dont get enough breast milk. Infants with breast milk jaundice, on the other hand, can properly latch onto the breast and receive adequate amounts of breast milk. Any signs of jaundice in your infant should be che…
Prevention
- Doctors dont know why jaundice occurs in infants who adapt well to breast-feeding. However, it may be caused by substances in breast milk that block the proteins in the liver responsible for breaking down bilirubin. Breast milk jaundice can occur in any breast-fed newborn. Since doctors dont know the exact cause of the condition yet, there are few ...
