Neonatal Jaundice – Causes and Management
“Should I worry about neonatal jaundice?”
Neonatal jaundice, where a newborn’s skin and eyes turn yellow,
is a common condition that usually resolves on its own.
However, in some cases, careful monitoring or treatment may be required.
Today, we will explore the causes and management of neonatal jaundice.
📌 Introduction
Neonatal jaundice is a condition where a newborn’s bilirubin levels increase,
causing yellow discoloration of the skin and eyes.
It occurs in about 60% of full-term newborns and 80% of preterm babies,
making it a relatively common condition.
✅ Most cases are physiological jaundice, which resolves naturally.
✅ However, pathological jaundice may require early medical intervention.
💡 In this article, we will discuss the causes, types, and management of neonatal jaundice.
Causes and Types of Neonatal Jaundice
Neonatal jaundice occurs when excess bilirubin accumulates in the baby’s bloodstream.
Bilirubin is a byproduct of red blood cell breakdown,
which is typically processed by the liver and excreted.
However, since newborns have immature liver function,
bilirubin clearance is slower, leading to jaundice.
Jaundice can be categorized into physiological jaundice and pathological jaundice.
1️⃣ Physiological Jaundice
✔ Occurs in most newborns and is a normal condition
✔ Begins within 2 to 4 days after birth and resolves naturally within 1 to 2 weeks
✔ In preterm babies, it may last longer (up to 3 weeks or more)
🔹 Main Causes
– Immature liver function slows bilirubin metabolism
– High red blood cell turnover after birth (transition from fetal to adult hemoglobin)
– Lack of gut bacteria delays bilirubin excretion
⚠ Treatment is usually unnecessary, but monitoring may be required if levels are high.
2️⃣ Breast Milk Jaundice
✔ Occurs between the 1st and 2nd week of life and can last for 3 to 12 weeks
✔ Certain components in breast milk inhibit bilirubin breakdown
✔ Breastfeeding can continue, as the condition is usually self-limiting
🔹 Main Causes
– Hormones and enzymes in breast milk slow bilirubin clearance
– Gut microbiome development affects bilirubin metabolism
⚠ In severe cases, temporary formula feeding may be considered.
3️⃣ Pathological Jaundice
✔ Unlike physiological jaundice, it may indicate an underlying medical issue
✔ Appears within the first 24 hours of life or lasts beyond two weeks
✔ Extremely high bilirubin levels can lead to brain damage (kernicterus)
🔹 Main Causes
– ABO or Rh incompatibility → Rapid red blood cell destruction due to immune response
– Liver dysfunction → Congenital liver disorders can impair bilirubin clearance
– Infections (e.g., sepsis) → Neonatal infections can worsen jaundice
– Genetic factors → Enzyme deficiencies (e.g., G6PD deficiency) prolong jaundice
⚠ Pathological jaundice requires urgent diagnosis and treatment. Immediate medical attention is crucial.
💡 Summary of Neonatal Jaundice Types
✔ Physiological Jaundice → Resolves naturally, caused by immature liver function
✔ Breast Milk Jaundice → Linked to breast milk components, breastfeeding can continue
✔ Pathological Jaundice → Caused by blood incompatibility, liver disease, or infection, requires urgent care
Most neonatal jaundice cases are normal physiological processes,
but some cases require medical attention to prevent complications.
Proper observation and timely intervention are essential!
Management and Treatment of Neonatal Jaundice
Most cases of neonatal jaundice resolve naturally without medical intervention.
However, if bilirubin levels become too high, proper treatment is required.
The management approach varies based on the severity of jaundice.
1️⃣ Mild Jaundice Management (Resolves Naturally)
✔ Increase breastfeeding or formula feeding
– Frequent feeding helps eliminate bilirubin through bowel movements
– Newborns should be fed at least 8–12 times per day
✔ Sunlight Exposure (Natural Light Therapy)
– Expose the baby to gentle sunlight through a window for 10–15 minutes
– Avoid direct sunlight and ensure skin protection
✔ Monitor Urine & Stool Color
– Stool should gradually change from pale yellow to green as jaundice improves
– Dark-colored urine may indicate severe jaundice and requires medical attention
⚠ Mild jaundice usually resolves within 1–2 weeks without intervention.
2️⃣ Phototherapy (For High Bilirubin Levels)
✔ Most common treatment for neonatal jaundice
✔ Uses special blue light to break down bilirubin in the skin
✔ Usually conducted in hospitals, but home-based phototherapy may be available
🔹 How It Works
1. The baby is placed in a special incubator under blue light
2. Eye protection is provided to prevent light exposure damage
3. Hydration and feeding are maintained, and bilirubin levels are monitored
⚠ If jaundice persists after phototherapy, further treatment may be needed.
3️⃣ Exchange Transfusion (For Severe Cases)
✔ Emergency treatment for dangerously high bilirubin levels
✔ Used in cases of ABO or Rh incompatibility leading to severe jaundice
🔹 How It Works
– A portion of the baby’s blood is replaced to rapidly remove excess bilirubin
– This procedure is rare but necessary in severe cases of kernicterus risk
⚠ Requires intensive hospital monitoring and immediate intervention.
4️⃣ When to Seek Medical Attention
✅ Jaundice appears within the first 24 hours of life
✅ Jaundice persists beyond two weeks
✅ The baby shows poor feeding, lethargy, or decreased activity
✅ Worsening jaundice with dark urine or pale stools
💡 If any of these symptoms occur, immediate medical consultation is necessary.
💡 Summary of Neonatal Jaundice Management & Treatment
✔ Mild Jaundice → Resolves naturally with frequent feeding & sunlight exposure
✔ Moderate Jaundice → Treated with phototherapy (blue light therapy)
✔ Severe Jaundice → May require exchange transfusion in extreme cases
✔ Seek medical attention if symptoms persist or worsen
Most cases of neonatal jaundice resolve on their own,
but early detection and treatment are crucial for severe cases.
Prevention and Home Care for Neonatal Jaundice
Neonatal jaundice often resolves naturally,
but proper care can help prevent or reduce its severity.
Key factors in jaundice prevention include feeding, bowel movements, and environmental control.
1️⃣ Ensure Sufficient Breastfeeding or Formula Feeding
✔ Adequate feeding in the first week is crucial
– Bilirubin is excreted through stool, so frequent feeding is essential
– Breastfeeding: At least 8–12 times per day
– Formula feeding: At least 6–8 times per day
✔ Breastfeeding should continue
– Breast milk jaundice does not typically require stopping breastfeeding
– If severe jaundice occurs, temporary formula supplementation may be considered
🚫 What to Avoid
– Assuming jaundice will disappear naturally while feeding remains insufficient
– Ignoring signs of lethargy or reduced feeding in the newborn
2️⃣ Monitor Bowel Movements
✔ Frequent bowel movements help eliminate bilirubin
– At least 3–4 bowel movements per day during the first week is normal
– As jaundice improves, stool color changes from pale yellow to greenish
🚫 Warning Signs
– Very pale or white-colored stool → Possible liver dysfunction
– Fewer than 1–2 bowel movements per day may indicate prolonged jaundice
3️⃣ Sunlight Exposure & Environmental Control
✔ Sunlight exposure helps bilirubin breakdown
– Place the baby near a window for 10–15 minutes of indirect sunlight
– Avoid direct sun exposure and prolonged outdoor time
✔ Maintain proper indoor temperature & humidity
– Ideal room temperature: 22–24°C (72–75°F)
– Humidity level: 40–60% to prevent dehydration
🚫 What to Avoid
– Direct sunlight exposure without protection
– Keeping the baby in an environment that is too cold or dry
4️⃣ When to See a Doctor Immediately
✅ Jaundice appears within the first 24 hours of birth
✅ Jaundice persists beyond two weeks or worsens over time
✅ The baby refuses to feed and appears lethargic
✅ Yellow discoloration spreads to palms and soles
✅ Dark brown urine or pale stools
💡 If any of these symptoms appear, seek medical attention immediately.
💡 Summary of Neonatal Jaundice Prevention & Home Care
✔ Frequent feeding → Promotes bilirubin excretion through stool
✔ Monitor bowel movements → Normal stool color & frequency indicate improvement
✔ Sunlight exposure → Helps break down bilirubin naturally
✔ Maintain indoor conditions → Prevent dehydration with proper temperature & humidity
✔ Seek medical help if jaundice worsens or persists
Neonatal jaundice is a natural process that often resolves with proper care,
but parents should closely monitor their baby to ensure symptoms do not worsen.
