📚 Understanding Newborn Jaundice

👶

What is Jaundice?

Yellowing of skin and eyes caused by elevated bilirubin levels. Very common in newborns.

🔬

Bilirubin Explained

A yellow pigment created when red blood cells break down. Newborn livers process it slowly.

☀️

Phototherapy

Special blue lights help break down bilirubin in the skin so it can be eliminated.

🍼

Breastfeeding

Frequent feeding (8-12 times daily) helps baby eliminate bilirubin through stool.

Peak Time

Jaundice typically peaks at 3-5 days of age in full-term babies.

Usually Harmless

Most cases resolve naturally. Severe untreated jaundice is rare but serious.

🚨 When to Call Your Doctor Immediately

Contact your pediatrician or go to the emergency room if you notice any of these signs:

🟡

Jaundice appearing in first 24 hours of life

📈

Rapidly increasing bilirubin levels

😴

Baby very sleepy, difficult to wake for feeds

🍼

Poor feeding or refusing to eat

😢

High-pitched crying or extreme fussiness

💪

Arching back or stiff, unusual movements

🌡️

Fever over 100.4°F (38°C)

🟨

Jaundice spreading to arms, legs, or whites of eyes

💊 Treatment Options

💡

Phototherapy

Special blue lights placed over baby's skin

When used: Most common treatment for moderate jaundice
Duration: 1-2 days typically
Notes: Baby wears eye protection, increases fluid needs
🍼

Enhanced Feeding

Frequent breastfeeding or formula feeding

When used: Mild jaundice, prevention
Duration: Ongoing
Notes: 8-12 feeds per 24 hours, monitor wet diapers
💉

IV Fluids

Intravenous fluids if baby is dehydrated

When used: Dehydration, difficulty feeding
Duration: Until hydration restored
Notes: Used alongside phototherapy if needed
🏥

Exchange Transfusion

Replace baby's blood with donor blood

When used: Severe jaundice not responding to phototherapy
Duration: Several hours
Notes: Rare, used only in critical cases

📈 About the Bhutani Nomogram

What is the Bhutani Nomogram?

The Bhutani nomogram is a widely-used medical chart that plots a baby's bilirubin level against their age in hours. It divides babies into risk zones based on where their bilirubin level falls compared to expected ranges.

Low Risk Zone

Below 40th percentile. Routine monitoring.

Low-Intermediate

40th-75th percentile. Close monitoring.

High-Intermediate

75th-95th percentile. Likely needs treatment.

High Risk Zone

Above 95th percentile. Urgent treatment needed.

Why Age in Hours Matters

Bilirubin levels naturally rise in the first few days after birth as the baby's liver learns to process it. A level of 10 mg/dL at 24 hours is more concerning than the same level at 72 hours. The nomogram accounts for this expected rise.

🛡️ Preventing Severe Jaundice

🍼 Feed Frequently

  • • Breastfeed 8-12 times per day
  • • Start within the first hour after birth
  • • Wake baby if needed to feed
  • • Ensure baby is latching well
  • • More feeding = more stool = more bilirubin eliminated

👁️ Monitor Closely

  • • Check skin color in natural daylight daily
  • • Gently press skin on forehead or nose
  • • Note if yellow color is spreading
  • • Track number of wet and dirty diapers
  • • Attend all scheduled follow-up appointments

🩸 Know Your Blood Type

  • • ABO or Rh incompatibility increases risk
  • • Your doctor will monitor more closely
  • • May need earlier bilirubin testing
  • • Treatment thresholds may be lower
  • • Inform all healthcare providers

📅 Follow-Up Care

  • • First checkup within 3-5 days after birth
  • • Earlier if discharged before 48 hours
  • • Bilirubin testing as recommended
  • • Don't skip appointments
  • • Call with any concerns between visits

🔬 Types of Newborn Jaundice

Physiological Jaundice (Most Common)

Appears: After 24 hours of life, peaks at 3-5 days

Cause: Normal adjustment as baby's liver learns to process bilirubin. Affects 60% of full-term and 80% of premature babies. Usually resolves on its own within 1-2 weeks.

Breastfeeding Jaundice

Appears: First week of life

Cause: Not getting enough breast milk, leading to dehydration and fewer stools. Solved by increasing feeding frequency and ensuring good latch. Don't stop breastfeeding!

Breast Milk Jaundice

Appears: After first week, can last several weeks

Cause: Substances in breast milk that slow bilirubin processing. Baby is healthy and gaining well. Harmless and resolves without treatment. Continue breastfeeding.

⚠️ Pathological Jaundice (Serious)

Appears: Within first 24 hours of life

Causes: Blood type incompatibility (ABO/Rh), infection, bleeding, genetic conditions, liver problems. ALWAYS requires immediate medical evaluation and treatment.

❌ vs ✅ Jaundice Myths & Facts

MYTH

"Sunlight through a window will cure jaundice"

FACT

Window glass blocks UV rays needed. Medical phototherapy with special blue lights is required for treatment.

MYTH

"All jaundice is harmless and will go away on its own"

FACT

While most jaundice is harmless, severe untreated jaundice can cause kernicterus (permanent brain damage). Always monitor levels.

MYTH

"Stop breastfeeding if baby has jaundice"

FACT

Continue breastfeeding! Frequent feeding (8-12 times daily) helps eliminate bilirubin. Only stop if doctor specifically advises.

MYTH

"Jaundice always means something is seriously wrong"

FACT

Most jaundice is physiological (normal). Over half of babies develop some jaundice. It's the monitoring and treatment when needed that's important.

⚖️ Important Medical Disclaimer

This calculator is for educational purposes ONLY and is NOT a medical diagnostic tool. It provides general risk assessment based on simplified nomogram guidelines.

Critical Limitations:

  • • This calculator uses simplified Bhutani nomogram curves and may not match exact clinical guidelines
  • • It does NOT replace laboratory bilirubin testing and medical evaluation
  • • Risk zones are approximations based on general population data
  • • Individual babies may require different treatment thresholds
  • • Visual assessment of jaundice is unreliable - blood tests are required

ALWAYS consult your pediatrician if:

  • • Your baby develops jaundice in the first 24 hours
  • • Jaundice appears to be worsening or spreading
  • • Your baby is not feeding well or seems lethargic
  • • You have ANY concerns about your baby's health
  • • Your baby was discharged before 48 hours of age

⚠️ EMERGENCY: Jaundice appearing in the first 24 hours of life or rapidly rising bilirubin levels require IMMEDIATE medical attention. Go to the emergency room or call 911.

This calculator is based on American Academy of Pediatrics (AAP) guidelines and Bhutani nomogram principles, but is simplified for educational use and should not be used for clinical decision-making.
