What is Jaundice?

Jaundice is a very common occurrence; almost all infants have jaundice to a certain degree. Jaundice is diagnosed as a yellowish tint to a baby’s skin. This occurs because of a high percentage of “bilirubin" in the skin tissue.

Jaundice babies almost always have a common type of jaundice called physiologic jaundice, which is not dangerous, it only becomes a problem when the bilirubin levels rise over a certain level.

Unborn babies need lots of red blood cells to get enough oxygen from a mother’s blood. When they are born, they don’t need all those additional red blood cells, because they are getting enough oxygen through breathing.

All the extra blood cells need to be broken down and eliminated from a baby’s body. Bilirubin is the byproduct formed by the breakdown of these extra blood cells. Now when a baby’s liver doesn’t get rid of this by-product quick enough, it causes jaundice. Jaundice is, therefore, even more, prevalent in preemies.

Types of Jaundice

  • Physiologic jaundice.

~ This is the typical type of jaundice that affects most babies. This type of jaundice usually only lasts about four days.

~ Breastfeeding can help avoid jaundice by ensuring that a baby excretes the bilirubin through stools, as colostrum acts as a laxative, which encourages this process.

~ Phototherapy “Bilirubin Lights" is often used as a treatment; It is a blue light that breaks down the bilirubin in the body, getting it excreted easily. This therapy usually only lasts a day or two. Nowadays,  babies can be taken home using a bili-blanket “fiber optic blanket" (photo-therapy lights that wrap around the baby).

  • Pathologic Jaundice (abnormal jaundice).

~ In extreme cases, babies may be given blood transfusions if phototherapy is not helpful. If left untreated baby might develop brain damage.

~ Pathologic Jaundice is usually caused by prematurity, stress from a difficult birth, or having a diabetic mother.

~ Mom should still continue to breastfeed her baby.

  • Late-onset jaundice

~ Usually happens during the second week of a baby’s life

~ It relates to breastfeeding; Caused by a mother’s milk enzymes hampering the breakdown of bilirubin or caused by the fatty acids in a mom’s milk that is being processed more than the bilirubin.

~ Breastfeeding should continue as this type of jaundice cannot harm a baby, and levels will return to normal within two or three months. Most exclusively breastfed babies who are completely healthy and gaining weight well, are still jaundiced at 5-6 weeks of life and even later.

  • Jaundice caused through not enough breast milk.

~ Jaundice can be caused by a bad latch. Or a weak suck.

~ A lactation aid can be used if milk supply is deficient.

  • Blood group incompatibility (Rh or ABO problems)

~ This is when a mother’s blood type is different from baby’s and her breast milk can actually start breaking down his/her red blood cells. This is very rare, but can be prevented with an immune injection.

Breastfeeding and jaundice fact - The fastest way to get rid of normal or Pathologic Jaundice is to breastfeed and breastfeed as much as possible.

Treat / Prevent Normal Physiologic Jaundice

  • Breastfeed your baby as soon as possible, so that your baby can get the benefits of colostrum and its laxative properties.
  • Do not give your baby water or any other supplements. Bilirubin is excreted in feces, and not urine. The more water you give your baby, the less hungry he/she will be, which will keep him/her from drinking colostrum.
  • Breastfeed your baby at least every two hours.
  • If for some reason you cannot breastfeed, you can pump exclusively and use alternative feeding methods, until your baby is ready to breastfeed.
  • Keep your baby in a room that has a lot of sunlight in it. Do not put your baby in direct sunlight though.
  • Do not take medication that contains aspirin and sulfa.

Symptoms to Look Out for That Indicate a Bad Case of Jaundice

  • When your baby’s urine turns brown.
  • Your baby’s eyes become yellow.
  • Your baby has a fever over 37.8° Celsius.
  • If your baby starts to act sick or becomes more yellow in skin color.
    If your baby is not drinking enough breast milk.
  • If baby sleeps more than usual. How to encourage baby to stay awake while breastfeeding.
