Does your newborn baby's skin look yellow? Jaundice is common and usually nothing to worry about.
If your newborn's beautiful skin has started turning a bit yellow, it could be jaundice. But your baby is in good company: Many infants experience this usually benign condition shortly after birth. Here are the basics on jaundice in newborn babies.
What is jaundice in babies?
Jaundice is a common, short-term condition in newborns that turns a baby's skin and the whites of the eyes yellow. Jaundice occurs in about 60 percent of all babies born full-term and about 80 percent of babies born prematurely when a chemical called bilirubin builds up in the baby's blood.
Most cases show up two to three days after birth and are caught by in-hospital screens for babies, while others can appear later. Jaundice usually goes away on its own (or sometimes with mild treatment) with no ill effects. It usually lasts a week to 10 days, sometimes longer for premature babies.
What causes newborn jaundice?
Jaundice in a newborn baby is caused by excess levels of bilirubin, a condition known as hyperbilirubinemia. Bilirubin is an enzyme that's produced in the blood when the body breaks down old red blood cells.
Since a newborn's liver is underdeveloped, the bilirubin often doesn't get eliminated as efficiently, which can cause the skin, and sometimes the whites of the eyes, to turn yellow.
If your baby has jaundice, you’ll be able to notice the yellow tinge of her skin by gently pressing on her forehead or chest and watching the color return.
There are various causes for newborn jaundice depending on type:
What are the symptoms of jaundice in a newborn baby?
Although there isn't anything you can do to prevent jaundice, it's important to watch for the telltale signs and symptoms, especially since the condition may not develop until after you bring your baby home from the hospital. That way, you can seek treatment if necessary.
The main symptoms of newborn jaundice are:
Jaundice often appears on the face first and then spreads to the rest of the baby's body, including the chest, tummy, arms, legs and whites of the eyes. A good way to check is to place your baby in natural sunlight or under fluorescent lights and gently press her forehead and nose with your fingers.
If the skin appears yellow where you made the impressions, call your pediatrician. The doctor will probably want to examine your baby and take a blood sample to look at the bilirubin levels in her blood.
Jaundice can be harder to see in babies with darker skin. In darker-skinned babies, the yellowing may be more visible on the palms of the hands and soles of the feet, so check there. Also look at the pink skin inside your baby’s mouth in the gums and inner lips.
What are risk factors for jaundice?
While most babies have mild jaundice, some are at a greater risk, including:
If you’re breastfeeding, feed your baby every two to three hours, or about eight to 12 times a day. Feeding this often helps keep your baby’s bilirubin level down. If you’re having trouble breastfeeding, ask your baby's doctor, nurse or a lactation specialist for help. It takes time to get the hang of it.
How is newborn jaundice treated?
If there are moderate to high levels of bilirubin detected in your baby, you may be advised to expose her to sunlight or another type of phototherapy at home, which helps to break down the enzyme, making it easier for the body to eliminate.
However, because of newborns' substantial risk of sunburn with direct sunlight exposure, doctors these days are more likely to offer treatment with phototherapy (which places the baby under a certain type of bright lamp) or a special blanket or pad.
You may also be told to feed your baby as often as possible, without overfeeding, to encourage frequent bowel movements. That will also help get rid of the excess bilirubin, which gives stools a brownish-yellowish color.
In the most extreme form of jaundice, when bilirubin levels are abnormally high, the enzyme can build up in the brain. Left untreated, very severe jaundice can lead to an extremely rare condition called kernicterus, which can result in permanent brain damage.
Some hospitals are taking extra measures to monitor the levels of bilirubin in babies' blood through blood tests and follow-up visits to ensure that these very uncommon instances of kernicterus are not missed.
If your baby has more severe jaundice, she may need treatments such as:
How long does it take for newborn jaundice to go away?
Typically, jaundice goes away in a week to 10 days, though it sticks around for longer in premature babies.
If your baby is breastfed, jaundice can last a month or occasionally longer. If your baby is formula-fed, jaundice typically clears up within two weeks. If it lasts three weeks or longer, be sure to call the doctor.
How can newborn jaundice be prevented?
There's no way to prevent the most common type of newborn jaundice. Most cases occur because a baby’s liver is not mature enough to get rid of bilirubin in the bloodstream.
You can reduce your baby's risk of jaundice by:
Though it's important to watch for the symptoms of jaundice and talk to your pediatrician right away if you suspect your baby could have it, take comfort in the fact that in most newborns, jaundice is an extremely treatable, manageable, and mild condition that will likely go away in a matter of weeks.
