Yellowing of the eyes, also known as jaundice, is a condition that can affect newborns and infants. It may cause distress and concern for parents, but it is common and often temporary. Understanding what causes yellow eyes in infants can help parents know when to seek medical advice and how to manage the condition. In this article, we will explore the different causes of yellow eyes in infants, how to recognize it, and when medical intervention is necessary.
What Is Jaundice?
Jaundice is the yellowing of the skin, eyes, and mucous membranes due to an excess of bilirubin in the bloodstream.
Bilirubin is a yellow compound that is created when the liver breaks down old red blood cells. Normally, the liver processes bilirubin and excretes it in the stool.
However, if the liver is not functioning properly or if there is an excess of bilirubin, it can accumulate in the blood and cause jaundice.
In infants, jaundice is relatively common and can occur due to various reasons, some of which are harmless and some that require medical treatment. It is essential to distinguish between these causes to ensure that the infant receives appropriate care.
Common Causes of Yellow Eyes in Infants
There are several common causes of yellow eyes in infants, and they generally fall into two categories: physiological jaundice and pathological jaundice.
1. Physiological Jaundice
Physiological jaundice is the most common cause of yellow eyes in newborns. It is not a disease but a normal occurrence in many infants, especially those born prematurely. This type of jaundice typically appears within the first 24 to 72 hours after birth and resolves on its own within one to two weeks.
Why Does Physiological Jaundice Occur?
In newborns, the liver is still immature and may not be fully efficient at processing bilirubin. As a result, bilirubin builds up in the blood and causes the yellowish tint in the skin and eyes. In premature infants, this process may take longer due to the liver’s further immaturity.
2. Breastfeeding Jaundice
Breastfeeding jaundice is another common form of jaundice that can occur in infants who are breastfed. This type of jaundice usually occurs when the infant is not getting enough breast milk. When this happens, the baby might not be able to flush out bilirubin as effectively, leading to higher bilirubin levels in the blood.
Causes of Breastfeeding Jaundice
Several factors can contribute to breastfeeding jaundice, including insufficient milk supply, ineffective breastfeeding technique, or the baby not breastfeeding frequently enough. In some cases, it may also occur if the baby is not latching properly, which can affect milk intake.
3. Hemolytic Jaundice
Hemolytic jaundice happens when there is an excessive breakdown of red blood cells. This type of jaundice is less common but can be more serious. Hemolysis (the breakdown of red blood cells) can lead to higher levels of bilirubin than the liver can process. The excess bilirubin then accumulates in the blood and causes jaundice.
What Causes Hemolytic Jaundice?
Hemolytic jaundice can occur if there is a blood group incompatibility between the mother and the infant. For example, if the mother has Rh-negative blood and the baby has Rh-positive blood, this can cause the mother’s immune system to attack the baby’s red blood cells, leading to hemolysis.
Another cause of hemolytic jaundice is a condition called ABO incompatibility, which occurs when the mother’s blood type is different from the infant’s blood type.
4. Biliary Atresia
Biliary atresia is a rare but serious condition that affects the bile ducts in the liver. It occurs when the bile ducts are blocked or absent, preventing bile from being excreted properly. This blockage causes bilirubin to build up in the liver and bloodstream, resulting in jaundice.
Symptoms of Biliary Atresia
In addition to yellowing of the eyes and skin, babies with biliary atresia may experience dark urine, pale stools, and an enlarged abdomen. This condition typically requires surgery to correct, and early diagnosis is essential for effective treatment.
5. Liver Disease or Infection
Liver disease or infection can also cause jaundice in infants. Conditions such as hepatitis or metabolic disorders can impair the liver’s ability to process bilirubin properly, leading to jaundice. Infections that affect the liver, such as viral hepatitis, can cause the liver to become inflamed, further hindering its function.
Signs of Liver Disease in Infants
In addition to yellow eyes and skin, signs of liver disease may include poor feeding, lethargy, abnormal stool color, and a swollen abdomen. If an infant shows any of these symptoms, it is important to seek medical attention promptly.
6. Genetic Conditions
Certain genetic conditions can also lead to jaundice in infants. These conditions affect the way the liver processes bilirubin or the rate at which red blood cells are broken down.
Gilbert’s Syndrome
Gilbert’s syndrome is a mild, inherited disorder in which the liver has a reduced ability to process bilirubin. This condition typically does not cause severe symptoms and is often discovered during routine tests.
Although it can cause mild jaundice in infants, it is generally not a cause for concern.
7. Infection and Sepsis
Sepsis, a serious bloodstream infection, can cause jaundice in infants. When the body is fighting off an infection, the liver may become overwhelmed, making it difficult to process bilirubin. Infections can also cause inflammation of the liver, further hindering its function.
Recognizing Infection in Infants
In addition to jaundice, signs of infection in infants may include fever, poor feeding, irritability, difficulty breathing, and abnormal movements.
If an infant shows any of these signs, they should be evaluated by a healthcare provider immediately.
When Should You Worry About Yellow Eyes in Infants?
While jaundice is common in newborns, it is important to monitor your baby closely. Most cases of jaundice resolve on their own without any treatment. However, there are some situations when yellow eyes in infants may indicate a more serious problem that requires medical intervention.
Here are some signs to watch for:
Jaundice that develops within the first 24 hours of life: Jaundice that appears within the first day after birth may indicate a more serious condition, such as hemolytic jaundice or an infection. Immediate medical attention is necessary.
Jaundice that worsens or does not improve: If the jaundice persists or worsens after a few days, or if the baby’s bilirubin levels continue to rise, it may require medical treatment, such as phototherapy.
Other symptoms: If the infant exhibits other concerning symptoms, such as poor feeding, lethargy, or dark urine, medical advice should be sought immediately.
Treatment of Yellow Eyes in Infants
Treatment for jaundice in infants depends on the underlying cause and the severity of the condition. Some babies may require no treatment at all, while others may need interventions to lower their bilirubin levels.
Phototherapy
One of the most common treatments for jaundice in newborns is phototherapy. This treatment involves exposing the baby’s skin to special blue light, which helps break down bilirubin in the skin. Phototherapy is safe and effective and is often used to treat moderate to severe jaundice.
Blood Transfusion
In cases of severe jaundice, such as hemolytic jaundice, a blood transfusion may be necessary to replace damaged red blood cells and reduce bilirubin levels quickly.
Medications
If the jaundice is caused by an infection or liver disease, medications may be prescribed to treat the underlying condition.
Surgery
In rare cases, such as with biliary atresia, surgery may be required to correct the blockage in the bile ducts and allow normal bile flow.
Conclusion
Yellow eyes in infants are most commonly caused by jaundice, which can occur due to a variety of reasons. While it is often harmless and resolves on its own, it is essential to monitor the baby’s symptoms and seek medical advice if the jaundice persists or worsens.
