Baby Jaundice That Doesn't Go Away: What Could It Mean?

Biliary atresia is a rare liver condition in babies where bile cannot flow normally from the liver to the intestine. In this guide, we explain its warning signs, diagnosis, treatment options, and why recognising the condition early can make a difference.

Bile is a digestive fluid made by the liver. It helps the body digest fats and also carries certain waste products out of the liver. When bile cannot leave the liver properly, it can build up and gradually damage the liver.

However, persistent yellowing of the skin or unusual changes in a baby's stool or urine can sometimes point to a liver or bile duct problem. Knowing which symptoms require medical attention can help parents seek care sooner and avoid delays in diagnosis.

To understand biliary atresia and why early diagnosis matters, we spoke with Dr Ankit Gupta, Senior Consultant, Gastroenterology, Hepatology & Endoscopy, Max Hospital, Shalimar Bagh.

What Is Biliary Atresia?

Biliary atresia is a rare condition that affects the bile ducts, the small tubes that carry bile from the liver to the intestine. In babies with this condition, the bile ducts become damaged, narrowed, or blocked. Biliary atresia usually becomes noticeable during the first few weeks of life.


What Causes Biliary Atresia?

Researchers are still studying why biliary atresia develops, and possible contributing factors include:

  • Changes in how the bile ducts develop before or around birth
  • Abnormal immune responses affecting the bile ducts
  • Certain infections that may trigger inflammation
  • Genetic or biological factors that may increase susceptibility
  • Environmental influences that are not yet clearly identified

What Are the Signs of Biliary Atresia?

The symptoms may not be obvious immediately after birth.

Common signs can include:

  • Jaundice
  • Pale or clay-coloured stools
  • Dark urine
  • Poor weight gain
  • An enlarged liver
  • Abdominal swelling

Why Does Early Diagnosis Matter?


Biliary atresia can cause progressive liver damage if treatment is delayed. Early diagnosis lets doctors perform the necessary tests and determine the right treatment as soon as possible.Dr Ankit Gupta, Senior Consultant, Gastroenterology, Hepatology & Endoscopy, Max Hospital, Shalimar Bagh
Therefore, evaluate persistent jaundice promptly, even if the baby otherwise seems well. Early testing also helps doctors determine whether jaundice is due to biliary atresia or another condition.

How Is Biliary Atresia Diagnosed?

Doctors may combine different tests to confirm the diagnosis and understand how the baby's liver and bile ducts are affected:

Diagnosis may include:

  • Blood Tests: Check bilirubin and liver function.
  • Abdominal Ultrasound: Looks for changes in the liver, gallbladder, and bile ducts.
  • Specialised Imaging: Assesses the bile ducts and bile flow.
  • Liver Biopsy: Checks for inflammation and liver damage.
  • Cholangiography: Helps confirm whether the bile ducts are blocked or absent.

How Is Biliary Atresia Treated?

Treatment is planned by a specialist team based on the baby's liver condition and how well bile can drain:

  • Kasai Portoenterostomy: This is usually the first treatment. Surgeons remove the damaged bile ducts and connect the intestine to the liver to create a new route for bile drainage.
  • Liver Transplant: If the liver becomes severely damaged or the Kasai procedure does not provide adequate bile flow, a liver transplant may be recommended.

What Happens After Treatment?

Babies treated for biliary atresia need long-term medical follow-up. Doctors may monitor liver function, growth, nutrition, vitamin levels, and signs of complications.

Some children may continue to have liver-related problems even after successful surgery. Regular follow-up allows the medical team to identify concerns early and provide appropriate support.

Parents may also receive guidance about feeding, medicines, vitamins, and signs that require medical attention.

When Should Parents Seek Medical Care?

Medical evaluation is important when jaundice does not settle as expected or when a baby's overall health seems to be changing. Parents should contact a paediatrician if:

  • Jaundice continues or becomes more noticeable over time.
  • The baby's feeding pattern or growth is not progressing normally.
  • The baby appears increasingly unwell, weak, or less responsive than usual.
  • The abdomen looks more swollen than expected.
  • There are concerns about the baby's urine or stool colour.
  • A healthcare professional has previously noted an abnormal bilirubin level or liver test.
Biliary atresia requires timely medical attention because liver damage can progress quickly in affected babies. Parents should not ignore ongoing concerns about their baby’s health or development. Early assessment allows specialists to investigate the cause, discuss appropriate treatment, and provide continued monitoring to support the child’s growth and liver health.

FAQs on Baby Jaundice That Doesn't Go Away: What Could It Mean?

  1. Is biliary atresia inherited from parents?
    Usually, biliary atresia does not follow a straightforward inherited pattern. Researchers are investigating genetic and biological factors, but most cases cannot be linked to a specific inherited cause.
  2. What happens if biliary atresia is diagnosed late?
    Delayed diagnosis can allow progressive liver damage to occur before treatment begins. This is one reason persistent jaundice in a young baby should be evaluated rather than automatically considered normal.
  3. Can biliary atresia be detected during pregnancy?
    In most cases, it is difficult to identify before birth. Some related abnormalities may occasionally be seen on prenatal imaging, but the condition is generally recognised after the baby develops signs following delivery
