Jaundice is a common condition in newborns, often causing concern for new parents. It occurs when a baby’s blood contains high levels of bilirubin, a yellow pigment that is produced when the body breaks down old red blood cells. While jaundice can be a natural part of a newborn’s adjustment to life outside the womb, excessive bilirubin levels can lead to complications. Understanding what helps lower bilirubin in newborns is essential for their health and well-being.
What is Bilirubin?
Bilirubin is a yellow substance produced during the breakdown of red blood cells. It is processed by the liver, which usually removes it from the bloodstream. In newborns, especially premature babies, the liver might not be fully mature enough to process bilirubin efficiently. As a result, the bilirubin builds up in the blood, leading to jaundice. This condition is quite common, affecting about 60% of full-term babies and almost 80% of premature infants.
Jaundice typically causes the skin and the whites of the eyes to turn yellow. While this condition is usually harmless and resolves on its own, high bilirubin levels can be dangerous if left untreated.
Causes of High Bilirubin in Newborns
Several factors contribute to high bilirubin levels in newborns:
Immature liver: Newborns’ livers are not always fully developed, especially in premature infants, which can delay bilirubin processing.
Breastfeeding: In some cases, breastfed babies may develop breastfeeding jaundice. This is due to insufficient milk intake in the first few days of life, leading to dehydration and a slower elimination of bilirubin.
Blood type incompatibility: If a mother’s and baby’s blood types are incompatible, it can lead to increased red blood cell breakdown, raising bilirubin levels.
Prematurity: Premature babies have more red blood cells than full-term babies, which leads to more bilirubin production.
Bruising during birth: Any trauma during birth, such as forceps delivery, can cause internal bleeding, which increases the breakdown of red blood cells and raises bilirubin levels.
How to Lower Bilirubin in Newborns
While jaundice usually resolves on its own, there are steps parents can take to help lower bilirubin levels in their newborns. The main goal is to assist the body in processing and eliminating bilirubin more efficiently.
1. Increased Feeding
One of the most effective ways to lower bilirubin levels in newborns is to ensure they are feeding well. Frequent feeding helps the baby pass stools, which is the primary way bilirubin is eliminated from the body.
For breastfed babies, it is recommended to breastfeed every 2 to 3 hours in the early days of life. The more the baby feeds, the more likely it is that bilirubin will be excreted through the stool.
If a baby is not feeding well, either due to tiredness or a breastfeeding issue, parents should consider supplementing with formula. In some cases, using pumped breast milk can also be helpful. It’s important to ensure that the baby is hydrated and getting enough nutrition to support the breakdown of bilirubin.
2. Phototherapy (Light Therapy)
Phototherapy is a common treatment for newborn jaundice. It involves exposing the baby to a special type of light that helps break down bilirubin in the skin. The light changes the shape and structure of the bilirubin molecules, making it easier for the baby’s body to eliminate them.
There are different types of phototherapy treatments. The most common involves placing the baby under a light source, such as a fluorescent light, which shines directly on the baby’s skin. The baby is typically placed in a crib under the light, wearing only a diaper and eye protection to shield the eyes from the bright light.
In some cases, a portable phototherapy unit may be used, allowing the baby to be treated in the comfort of their home. However, if the bilirubin levels are very high, the baby may need to stay in the hospital for more intensive treatment.
3. Sunlight Exposure
A natural and gentle option to help reduce bilirubin levels is sunlight exposure. When a baby is exposed to sunlight, the ultraviolet rays can help break down the bilirubin in the skin. However, this method should be used cautiously.
Parents should place the baby in a well-lit room with indirect sunlight. Direct exposure to the sun is not recommended, as it can cause overheating or skin damage. It’s best to expose the baby’s body to sunlight for short periods, about 10 to 15 minutes per day, while keeping the baby protected from sunburn.
While sunlight exposure can be a helpful addition, it should not replace medical treatments like phototherapy if jaundice is severe.
4. Hydration
Ensuring the baby stays well-hydrated is crucial for the breakdown and elimination of bilirubin. Dehydration can slow down the process of bilirubin excretion through the urine and stool, leading to higher bilirubin levels.
For breastfeeding mothers, ensuring an adequate milk supply is key. If the baby is not feeding enough or not latching properly, it is important to seek guidance from a lactation consultant to improve feeding. This will ensure that the baby is getting enough milk to stay hydrated and help lower bilirubin.
Formula-fed babies also need to be fed frequently to maintain hydration and promote proper digestion. In cases where a baby shows signs of dehydration, such as fewer wet diapers, it’s important to consult with a healthcare professional.
5. Treating the Underlying Cause
In some cases, high bilirubin levels are caused by conditions such as blood type incompatibility, infection, or other health issues. Treating the underlying cause is essential to help resolve jaundice and prevent complications.
For example, if jaundice is caused by an infection, antibiotics may be prescribed. If the jaundice is due to blood type incompatibility, treatments like exchange transfusion may be necessary to lower bilirubin levels quickly and safely.
In cases of severe jaundice, the healthcare provider may monitor the bilirubin levels closely and recommend further treatment, such as a blood transfusion, to prevent damage to the baby’s brain.
6. Monitoring Bilirubin Levels
Parents should work closely with their pediatrician to monitor their baby’s bilirubin levels. Blood tests are typically done to determine the level of bilirubin in the baby’s bloodstream. If the bilirubin level is high, the pediatrician will recommend the most appropriate treatment based on the severity of the jaundice.
In some cases, bilirubin levels can rise rapidly in the first few days of life, so regular follow-up visits with the doctor are essential to ensure the baby is improving.
When to Seek Medical Attention
Most cases of jaundice in newborns are mild and resolve on their own. However, there are times when jaundice can be more serious and requires medical attention. Parents should seek immediate help if:
- The baby’s jaundice worsens or doesn’t improve after a few days.
- The baby is lethargic, hard to wake, or not feeding well.
- The baby’s skin appears more yellow, especially in the palms of the hands or the soles of the feet.
- The baby has difficulty breathing or a fever.
Conclusion
While jaundice in newborns is a common condition, it’s important for parents to monitor their baby’s bilirubin levels closely. By ensuring frequent feeding, staying hydrated, using phototherapy, and following medical advice, most babies can recover from jaundice without complications. If there are concerns about jaundice, parents should always consult with a healthcare provider to ensure the baby receives the necessary care and treatment.
