Common liver problems in children usually are associated with viral infections and involve transient inflammation. Hepatitis A, B and C can occur but generally children are now immunised against Hepatitis B, and if they are travelling abroad Hepatitis A. Other viruses can cause liver problems, such as the virus that causes glandular fever – the Epstein Barr virus. If your child presents with jaundice or with liver blood test abnormalities then further investigations which might include abdominal ultrasound, further more sophisticated blood tests and other radiological imaging such as MRI scan. A liver biopsy is sometimes needed and this again will be discussed with you.
