Jaundice is a condition that causes the skin and parts of the eyes to turn a yellow color.
Breast milk jaundice is long-term jaundice in an otherwise healthy, breast-fed baby. It develops after the first week of life and continues up to the sixth week of life.
Bilirubin is a yellow pigment that is created as the body gets rid of old red blood cells. The liver helps break down bilirubin so that it can be removed from the body in the stool.
If jaundice occurs or lasts past the first week of life in an otherwise healthy and thriving breast-fed infant, the condition may be called "breast milk jaundice." It is probably caused by factors in the breast milk that block certain proteins in the liver that break down bilirubin.
Breast milk jaundice tends to run in families. It occurs equally often in males and females and affects 0.5% to 2.4% of all newborns.
Your child's skin, and possibly also the whites of the eyes (sclera) will look yellow.
Laboratory tests that may be done include:
In some cases, a blood test to check for glucose-6-phosphate dehydrogenase (G6PD) may be done. G6PD is a protein that helps red blood cells work properly.
Treatment will depend on:
Often, the bilirubin level is low (20 mg/dL is the usual normal limit for babies who are over a week old). Sometimes no treatment is needed, other than close follow-up.
Sometimes jaundice is caused by not enough breastfeeding (instead of from the milk itself). Extra fluids are helpful for babies who have not been getting enough breast milk.
To help break down the bilirubin, your child may be placed under special blue lights (phototherapy). If the bilirubin level is not too high or is not rising quickly, you can do phototherapy at home.
If the bilirubin level is above the usual limit and other causes have already been ruled out, the mother can stop nursing for 24 hours to see if the baby's bilirubin level goes down. Giving the baby formula will cause the bilirubin level to drop quickly in babies with breast milk jaundice.
The baby should recover fully with the right monitoring and treatment.
With the right treatment, there are usually no complications. However, babies who do not get the right medical care can have severe effects. High bilirubin levels can be harmful to the baby's brain and other organs.
Babies whose bilirubin levels have been unusually high may need follow-up hearing screening after the newborn period.
Call your health care provider right away if you are breastfeeding and your baby's skin or eyes become yellow (jaundiced).
Breast milk jaundice cannot be prevented. When the condition occurs and the baby is a yellow color, it is very important to have the baby's bilirubin level checked right away. If the bilirubin level is high, it is important to make sure there are no other medical problems.
You can treat jandice that is caused by not enough breastfeeding by making sure your baby is getting enough breast milk. Give your baby unlimited time at each breast, and feed about 10 to 12 times each day starting the first day of life. Get help from a lactation consultant or your doctor as soon as possible if you have any trouble breastfeeding.
