Living with Biliary atresia

A rare condition in which bile ducts are blocked or missing in newborns, causing long-lasting jaundice.

Understanding Biliary atresia

Biliary atresia is a rare bile duct disease in which the ducts inside and outside the liver become blocked, starting before or soon after birth.

It leads to severe and long-lasting yellowing of the skin (jaundice) in newborns and pale, clay-colored stools. Bile does not flow well from the liver.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Long-lasting jaundice in a newborn
  • Clay-colored stools
  • Dark yellow urine
  • Enlarged liver
  • Slow weight gain (failure to thrive)
  • Poor fat absorption

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include digestive system specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.
