According to the Mayo Clinic and the Johns Hopkins Children's Center, causes of elevated liver enzymes in children include viral infections and overdose of certain medications.
If your child is obese or has a diet high in fatty foods, elevated liver enzymes may result and are an indication of fatty liver disease.
Infections with hepatitis A virus through contaminated food or water, or with the hepatitis B or C viruses at birth may cause your child to have elevated liver enzymes.
