Icterus, also known as jaundice, is a common condition in newborns, where the skin and the whites of the eyes take on a yellowish tint. It happens due to an excess of bilirubin, a yellow pigment that is produced when red blood cells break down. In many cases, jaundice in newborns is mild and resolves on its own, but in some instances, it can be a sign of underlying health issues. It is essential for parents and caregivers to be able to recognize the signs of jaundice early, so the child can receive timely medical attention if needed.
This article will guide you through how to check for icterus (jaundice) in newborns. We will discuss the signs and symptoms, how to check for jaundice at home, when to seek medical help, and what treatments are available.
What Is Icterus (Jaundice)?
Icterus or jaundice occurs when there is an excess of bilirubin in the baby’s blood. Bilirubin is a substance produced by the breakdown of red blood cells. In newborns, especially during the first few days after birth, their liver may not yet be fully developed and might struggle to process bilirubin efficiently. As a result, bilirubin levels can rise and cause the yellowing of the skin and eyes.
Jaundice is common in newborns, especially in premature babies, and it usually appears on the second or third day after birth. The condition typically resolves on its own as the liver matures and becomes better at processing bilirubin. However, if bilirubin levels become too high or persist for too long, it can lead to more serious complications, including brain damage, which is why early detection and treatment are essential.
Types of Icterus in Newborns
There are different types of jaundice that can affect newborns, each with varying causes and implications:
Physiological Jaundice
This is the most common type of jaundice and typically appears within the first two to three days of life. It is caused by the normal breakdown of red blood cells and the liver’s immature ability to handle bilirubin. Physiological jaundice usually resolves without treatment within one to two weeks as the liver matures.
Breastfeeding Jaundice
This form of jaundice can occur when the baby is not getting enough breast milk. This can happen due to issues like poor latch or insufficient milk supply. As a result, the baby may not be able to clear the bilirubin from their system efficiently. Breastfeeding jaundice typically improves when feeding is increased and the baby receives more milk.
Breast Milk Jaundice
This type of jaundice occurs after the first week of life and is thought to be caused by substances in the mother’s milk that can interfere with the baby’s ability to process bilirubin. Breast milk jaundice is usually harmless and resolves on its own, although it may take several weeks to resolve fully.
Pathological Jaundice
Pathological jaundice is less common but more serious. It usually occurs within the first 24 hours of birth and is often caused by an underlying condition, such as an infection, blood group incompatibility (e.g., Rh or ABO incompatibility), or a liver disorder. Pathological jaundice requires medical intervention as it can lead to serious complications if not treated promptly.
How to Check for Icterus (Jaundice) in Newborns
Checking for jaundice in a newborn requires careful observation and understanding of the signs. Jaundice typically starts with the yellowing of the skin and eyes, but it is important to check systematically to ensure a proper assessment.
Step 1: Check the Baby’s Skin Tone
The first place to check for jaundice is the skin. Jaundice usually starts from the head and moves downward. To check for jaundice on the baby’s skin, gently press on a part of their body that is light in color, such as the forehead or the chest. After releasing the pressure, observe if the skin turns yellow. The yellowing of the skin is more noticeable on lighter-skinned babies, but it can be present in darker-skinned babies as well, although it may be more difficult to detect.
Step 2: Check the Eyes (Sclera)
One of the easiest ways to check for jaundice in newborns is by looking at the whites of the baby’s eyes, also known as the sclera. In newborns with jaundice, the sclera will often appear yellowish, starting in the corners of the eyes and gradually spreading toward the center. To check the sclera, gently lift the baby’s eyelid and examine the whites of the eyes. This is one of the most reliable indicators of jaundice.
Step 3: Check the Baby’s Palms and Soles
In some cases, jaundice may also affect the palms of the hands and the soles of the feet. This is more common in cases of more severe jaundice. To check for yellowing on the palms and soles, gently press on the skin and look for any yellow discoloration after releasing the pressure. Although this is not the first place to look, it can provide an additional clue when assessing the severity of jaundice.
Step 4: Observe the Baby’s Feeding and Behavior
In addition to physical signs, you should also observe your baby’s feeding habits and overall behavior. Babies with jaundice may experience difficulty feeding due to lethargy, and they may be more irritable than usual. Jaundice can also lead to poor weight gain, as the baby may not be able to feed effectively. If you notice that your baby is not feeding well or seems overly tired, it may be a sign of jaundice.
Step 5: Monitor the Onset and Progression of Symptoms
The timing and progression of jaundice symptoms can provide valuable information. Physiological jaundice typically begins within the first two to three days of life, and it gradually worsens before improving. On the other hand, pathological jaundice usually appears earlier, within the first 24 hours, and may worsen quickly. If you notice that the yellowing of the skin is worsening or spreading rapidly, it is important to seek medical attention immediately.
When to Seek Medical Help
If you notice any of the following signs, you should seek medical attention as soon as possible:
- Jaundice appearing within the first 24 hours of birth.
- Rapid progression or worsening of jaundice.
- Yellowing of the baby’s skin extending to the arms, legs, or abdomen.
- Lethargy, poor feeding, or difficulty waking the baby.
- The baby’s stool appears pale or clay-colored.
- The baby’s urine is dark in color (often described as tea-colored).
If you observe any of these symptoms, it’s essential to consult your pediatrician or healthcare provider immediately. Early intervention is crucial, especially in cases of pathological jaundice, to prevent complications.
Treatment Options for Icterus in Newborns
Treatment for jaundice depends on the cause and severity of the condition. Most cases of jaundice in newborns, especially physiological jaundice, do not require treatment beyond monitoring and ensuring the baby is feeding well. However, in more severe cases, medical treatment may be necessary.
1. Phototherapy (Light Therapy)
Phototherapy is the most common treatment for jaundice in newborns. It involves exposing the baby to a special type of light that helps break down bilirubin in the skin. The light helps the body eliminate excess bilirubin through the baby’s liver. The baby is usually placed under a special light source in a hospital or at home (in more severe cases), and the process may last for several hours or days, depending on the bilirubin levels.
2. Exchange Transfusion
In rare cases, if jaundice becomes severe and phototherapy does not lower bilirubin levels, an exchange transfusion may be necessary. This procedure involves replacing the baby’s blood with donor blood in small amounts, which helps remove the excess bilirubin and other toxins. Exchange transfusions are typically only performed in hospitals and under close medical supervision.
3. Adequate Feeding and Hydration
Ensuring that the baby is feeding well is one of the most important aspects of managing jaundice. Adequate feeding helps the baby pass more stool, which helps eliminate bilirubin from the body. Breastfeeding is encouraged, and if breastfeeding is not effective, formula feeding may be considered to ensure the baby is getting enough fluids and nutrition.
4. Treating Underlying Causes
If the jaundice is caused by an underlying condition, such as an infection or blood group incompatibility, treating the underlying cause is essential. For example, if the jaundice is caused by an infection, antibiotics may be prescribed. If it is caused by a blood type incompatibility, additional medical interventions may be required.
Conclusion
Jaundice in newborns is a common condition that usually resolves on its own, but it is important for parents and caregivers to be vigilant and check for signs of icterus early. Recognizing jaundice involves checking the baby’s skin, eyes, and overall behavior. If you suspect jaundice, monitor your baby closely and consult your pediatrician if necessary. In most cases, jaundice can be treated effectively with simple interventions like phototherapy and proper feeding. However, early detection and treatment are key to preventing complications and ensuring the baby’s healthy development.
