Jaundice in Newborns & Bilirubin Levels

The presence of enough bilirubin for yellow pigment to be visible on the skin is called jaundice. Jaundice occurs in about 60% of healthy term infants.


Dr. Greene, my 6-week old was diagnosed with breastfed jaundice when her bilirubin was taken at one week old. I am supposed to stop breastfeeding her for 24 hours (and give her formula) and am finding her resisting the bottle. Will the jaundice eventually go away and could there be any harm in not giving her the recommended 24-hour break from breastfeeding?

Dr. Greene's Answer

This week, while I was putting up lights to decorate for the holidays, I bruised my arm. I can remember, as a young child, watching bruises transform through a series of colors before they eventually disappeared.

What Causes Jaundice

Hemoglobin, the red pigment in red blood cells, must undergo a succession of changes before the body can dispose of it. Specific enzymes from our great processing center, the liver, carry out each step. Bilirubin, the yellow pigment responsible for jaundice, is a normal component in the breakdown of hemoglobin. Adults often turn yellow when they have hepatitis because their livers aren’t able to process the bilirubin.

Every day, about 1% of our red blood cells expire, to be replaced by fresh, young ones ready to carry oxygen to supply the body. Our lifeblood is new every 4 months.

A low level of bilirubin (about 1 mg/dL) circulates throughout our bodies as part of this process. This concentration is too faint to be visible.

Even before babies are born, this renewing of the blood is taking place. The placenta carries away the bilirubin as it is formed to the mother’s liver to be processed. After babies are born, they enter a transition period as their livers begin to assume this responsibility. Often, their immature livers can’t quite keep up.

The presence of enough bilirubin for the yellow pigment to be visible is called jaundice. Jaundice occurs in about 60% of healthy term infants and 80% of those born prematurely. If the bilirubin concentration rises to about 5 mg/dL, the face takes on a yellow appearance. If the level reaches about 15 mg/dL, the yellow tint is visible from the head down to the midabdomen. At a level of 20 mg/dL, even the soles of the feet are yellow (note: these are approximations and a blood test is required to know the true bilirubin level).

Bilirubin is found throughout the body, not just in the skin. Under certain conditions, high concentrations of bilirubin are toxic to babies’ brains. This is very rare when the concentration is under 25 mg/dL, but at higher concentrations, an increased risk for permanent hearing loss, mental retardation, spastic quadriplegia, or even death exists.

Causes of Rising Levels of Bilirubin

Anything that increases the number of expiring red blood cells soon after birth makes jaundice more likely. This might include the pounding babies take during difficult births (sometimes they look like little prizefighters) or the scalp hematomas caused by vacuum-assisted deliveries (one of my children looked like the ultimate conehead!). Sometimes extra red blood cells applying for social security are the result of a blood-type incompatibility, delayed cord clamping, a congenital anemia, or an infection.

Anything that makes it tougher for the immature liver to process the bilirubin can also lead to jaundice, including prematurity, lack of oxygen, poor feeding, thyroid deficiency, a genetic enzyme deficiency, or a liver otherwise occupied with dealing with an infection.

Pitocin, a drug commonly used to induce delivery, is also associated with increased bilirubin levels.

Physiologic Jaundice

The most common type of jaundice is called physiologic jaundice, the normal increased bilirubin in babies whose livers can’t quite keep up with a slightly increased load of red blood cells. This usually becomes visible on day 2 or 3 and peaks somewhere between days 2 and 4 as the liver gains control of the situation. The bilirubin levels usually fall substantially by day 7. Sometimes, they reach a level at which treatment is needed (>15 mg/dL before 48 hours old, >18 mg/dL before 72 hours old, > 20 mg/dL anytime–in otherwise healthy term babies). Stopping nursing is not recommended for physiologic jaundice, although supplementing feeds with pumped breast milk or formula may be helpful.

Breast-feeding Jaundice

There are two types of jaundice that are related to breast-feeding. They are called breast-feeding jaundice and breast milk jaundice. Breast-feeding jaundice is common and is a jaundice that may occur in the first week of life in breast-fed infants. The cause is thought to be due to decreased milk intake leading to dehydration or low caloric intake. The incidence of breast-feeding jaundice may be reduced by increasing the frequency of feeding and refraining from using water to replace breast milk (Nelson Textbook of Pediatrics, WB Saunders, 2007).

Breast Milk Jaundice

Breast milk jaundice is far less common, occurring in about 2% of breast-fed term babies. Here it is often not visible until the baby is a week old and then reaches its peak during the second or third week. The exact mechanism by which breast milk causes jaundice is uncertain. Breast milk jaundice may be caused by enzymes in mom’s milk that allow bilirubin to be reabsorbed into the blood from the intestines or by fatty acids in mom’s milk that the baby processes as a priority over processing the bilirubin. Or there may be an as yet unidentified mechanism.

Whichever the cause, if the mother continues to nurse her baby, the jaundice will decrease and disappear on its own, but this may take 3 to 10 weeks. If the mother stops nursing for 1 or 2 days, substituting formula, the bilirubin levels will drop rapidly. They will not rise again when the nursing is resumed.

Permanent damage or ill effects from breast milk jaundice is extremely rare. Phototherapy (lights used to lower bilirubin) may be used if the level of bilirubin is above 20 mg/dL. In breast milk jaundice, stopping breast milk for 1 to 2 days can help the bilirubin level drop rapidly. However, pediatricians and neonatologists generally agree that most babies who are well enough to feed may continue to feed on breast milk. This is true even when the bilirubin level is high enough to require phototherapy.

Even as I’m writing this article, my body is silently at work healing the bruise on my arm. As surely as that bruise will be gone by the new year, if your daughter has breast-feeding jaundice, she too will soon take care of her “pigment problem” herself–whether or not you take a break from nursing.

Also , baby was already in special care unit, because cord was twice wrapped around her neck.altho Dr. didn’t seem concerned.

What’s the average bilirubin level for a 12 day old newborn? 200 – 300?
Over 300 is consider bad? Thanks!

Dear dr. Greene
I am an Asian background, I had my son at 35 weeks and 4 days. When we left the hospital his level was 9ml per dl. Now we are 9 days old and his level has reached 16mg per ml. He drinks about 20-30 ml of breast milk every 2hours, but 95% of the time he is sleeping even when feeding. I am very worried. The doctor told me to put him on formula for a day and redo his blood work. I know that it can get lethal. I am very scared, I feel he is even having trouble breathing now. Should I just take him to the emergency room?

Hi Yujia,
Thank you for writing in! Dr. Greene’s article says, “The incidence of breast-feeding jaundice may be reduced by increasing the frequency of feeding and refraining from using water to replace breast milk.” Have you thought about trying to feed him more often? Please let us know how he’s doing, and trust your instincts.
Hope that helps!

Question, comment. My daughter had a baby boy on December 24, 2016. She was released with my grandson the following day at 8:00 p.m. She was told her baby borderlined a higher than normal bilirubin level. She was told to have him tested again with 48 hours. With all doctors and offices having different hours during Christmas, she got him in for a recheck on December 29th. His level was at 22. He was brought to the hospital at about 9:30 p.m. (because she didn’t get a call from the doctors office until this time) where he was immediately put under phototherapy. His levels dropped to 10.3 in 2 days and he was released.

My question is this. Since I know 25 is the critical level for neurological damage and at 5 days he was a 22 with really no indicator of what was going on in between, does this level generally slowly RISE over several days, or is there a chance at day 3 or 4, that his levels were higher than what is considered safe? Any insight on these levels and their fluctuations? thanks.


My son is 17 days old, exclusively breastfeeding, and his bilirubin level is 11.8. He had lights at days 5-6 with a level at 21. I have recently been diagnosed with NASH and also have elevated liver enzymes. I am wondering if my decreased liver function might be causing an increase in my own bilirubin and if that can be transferred to the baby in my breastmilk?

I have twins one girl baby one boy baby, girl have my blood group. Her bilirubin’s level is 19 any problem… Please give me answer….

Dear sir
Sir jandes bilirubin drite 7.8 and
bilirubin dendrite 8.7
Total bilirubin 15.8 and 41 years old fmale in Laver jandes 1year hospital Madison in no quar

Place suggest me sir comform normal bilirubin

My baby 1 week check up his jaundice was 9.4 , today at his almost 2 week check up appointment it was 11.1 ? I’m confused as to why she said it was normal for his age


As babies grow the normal bilirubin level goes up. In other words, the correct target number changes in relationship to your baby’s size. This is because the amount of bilirubin your baby can process goes up.

Hope that helps,
