Jaundice In Newborns: What's Normal And What's Not?

Jaundice is a common condition in newborn babies, affecting around 60% of newborns. It is caused by a high level of bilirubin in the blood, which is a yellow substance produced when red blood cells are broken down. While jaundice usually goes away without treatment, it is important to monitor your baby's condition and seek medical attention if you notice any concerning symptoms. In this paragraph, we will explore the topic of newborn jaundice, including its causes, symptoms, and treatment options.

Newborn jaundice is common and usually harmless

Newborn jaundice is a common condition, affecting about 60% of babies. It is caused by a high level of bilirubin in the blood, which is a yellow substance produced when red blood cells are broken down. During pregnancy, the placenta removes bilirubin from the baby's body, but after birth, the baby's liver starts doing this job. It may take some time for the baby's liver to be able to do this efficiently, and in the meantime, the excess bilirubin causes jaundice.

Jaundice is characterized by a yellowing of the skin and the whites of the eyes. This usually appears between the second and fourth day after birth and is more common in preterm babies and some breastfed babies. In most cases, jaundice is harmless and goes away on its own within 1 to 2 weeks without treatment. However, it is important to monitor jaundice and seek medical attention if it becomes severe or persists for longer than 2 weeks.

There are two types of jaundice that may occur in breastfed babies: breastfeeding jaundice and breast milk jaundice. Breastfeeding jaundice occurs when babies do not nurse well or the mother's milk is slow to come in, leading to dehydration. Breast milk jaundice may appear in healthy, breastfed babies after the first week of life and is likely due to substances in the breast milk affecting the breakdown of bilirubin in the liver. While these types of jaundice are usually harmless, it is important to have them checked by a healthcare provider to rule out more serious causes.

While newborn jaundice is typically harmless, in rare cases, very high levels of bilirubin can lead to brain damage, known as kernicterus. It is important to monitor your baby's jaundice and seek medical attention if you have any concerns.

Jaundice is caused by a build-up of bilirubin in the blood

Jaundice is a common condition in newborn babies, affecting around 60% of newborns. It is caused by a build-up of a substance called bilirubin in the blood. Bilirubin is a yellow pigment of red blood cells and is formed when hemoglobin breaks down as part of the normal process of recycling old or damaged red blood cells.

In newborns, jaundice occurs because the baby's liver isn't mature enough to get rid of bilirubin in the bloodstream. The liver is responsible for filtering bilirubin from the bloodstream and releasing it into the intestinal tract. However, a newborn's immature liver often can't remove bilirubin quickly enough, leading to a build-up in the blood. This build-up of bilirubin causes the yellow discoloration of the skin and eyes, known as jaundice.

Most cases of jaundice in newborns are mild and typically go away within a few weeks without treatment. However, in some cases, jaundice can indicate an underlying health condition. For example, severe jaundice can lead to brain damage if left untreated. Therefore, it is important to monitor newborns for jaundice and seek medical attention if symptoms of concern arise.

Jaundice in adults, on the other hand, is usually a sign of an underlying health condition, such as liver disease, gallstones, or hepatitis. In adults, jaundice can cause symptoms such as dark urine, light-colored stool, and itching all over the body. It is important for adults with jaundice to see a doctor to determine the underlying cause and receive appropriate treatment.

The condition usually resolves itself within 1-2 weeks

Jaundice is a common condition in newborns, with up to 60% of full-term babies and 80% of premature babies developing the condition during their first week of life. It is characterised by a yellow discolouration of the skin and eyes, caused by a buildup of bilirubin in the blood. Bilirubin is a yellow substance created when red blood cells break down.

The condition is usually harmless and resolves itself within 1-2 weeks, as the baby's liver matures and becomes more effective at processing bilirubin. This process typically takes a few days, and by the time a baby is about two weeks old, their liver is more effective at processing bilirubin, so jaundice often corrects itself by this age without causing any harm.

However, in rare cases, jaundice can be a sign of a more serious underlying health condition, particularly if it develops within the first 24 hours after birth. It is important to monitor the condition and seek medical advice if symptoms worsen or persist beyond two weeks.

If a baby has very high levels of bilirubin, there is a small risk of kernicterus, a rare condition where bilirubin passes into the brain and causes permanent brain damage. Treatment for jaundice may include phototherapy, where a baby is placed under special blue lights to help break down bilirubin, or in rare cases, an exchange transfusion of blood may be required.

Breastfed babies are more likely to develop jaundice

Jaundice is a common condition in newborn babies, with about 60% of newborns developing it. It is characterised by a yellow discolouration of the skin and eyes, caused by excess bilirubin in the blood. Bilirubin is a yellow pigment that is produced when the body breaks down old red blood cells.

To prevent jaundice caused by insufficient breastfeeding, it is recommended to feed the baby 8 to 12 times a day, or whenever the baby is alert and showing signs of hunger.

If jaundice is observed in a breastfed baby, it is important to have the baby's bilirubin levels checked by a healthcare provider. Treatment for jaundice may include phototherapy (light therapy) or, in rare cases, temporary interruption of breastfeeding for 12 to 48 hours.

In rare cases, jaundice can lead to brain damage

Jaundice is a common condition in newborn babies, affecting 60-80% of newborns. It is caused by a build-up of bilirubin, a yellow substance that forms when red blood cells break down, in the blood. In newborns, jaundice occurs because the baby's liver isn't mature enough to remove bilirubin from the blood quickly enough. Although jaundice usually goes away on its own and is harmless, in rare cases, it can lead to brain damage if left untreated.

Brain damage caused by severe, untreated jaundice is known as kernicterus. Kernicterus is a rare but extremely serious neurological condition that occurs when bilirubin levels in the blood become so high that they cross the blood-brain barrier and damage the brain tissue. This can affect several critical areas of the brain, including those involved in movement and hearing, potentially leading to cerebral palsy, hearing loss, other neurological issues, and even death.

The risk factors for kernicterus include premature birth, blood type differences between the mother and baby, trouble feeding, a family history of jaundice, dark skin, Mediterranean or East Asian descent, and bruising during birth. The symptoms of kernicterus include excessive sleepiness, high-pitched crying, muscle spasms, and arching in the neck and back.

Prompt treatment of jaundice is essential to prevent kernicterus and reduce the risk of brain damage. Treatment for jaundice typically involves light therapy or blood transfusions to lower bilirubin levels and prevent further brain damage.
