Question
What factors can lead to Congenital Biliary Atresia? How can newborns be diagnosed with this condition?
Answer
The exact cause of Congenital Biliary Atresia is not fully understood and may be related to various factors, including genetic inheritance, environmental factors, or other unknown reasons. In most cases, jaundice is the first symptom, usually appearing 2-3 weeks after birth. Other possible symptoms include pale or white stools, abdominal swelling, and more. Diagnosis is typically confirmed through imaging tests such as ultrasound or magnetic resonance cholangiopancreatography. Newborn jaundice screenings and liver function tests can also help detect this condition.
