Pediatric Metabolism Disorders

The chemical reactions in your body that turn food into energy are called metabolism. When these chemical reactions aren’t functioning properly, it is called a metabolism disorder.

What are pediatric metabolism disorders?

Pediatric metabolic disorders happen when a child’s body is not properly processing nutrients such as fats, proteins or sugars. Often, metabolism disorders are genetic conditions that are passed down in families. When older children develop a metabolism disorder, it is often due to obesity. This puts the child at a higher risk for diseases such as Type 2 diabetes and heart disease.

Conditions commonly treated include:

  • Biotinidase deficiency
  • Galactosemia
  • Glycogen storage disorders
  • Homocystinuria
  • Maple syrup urine disease (MSUD)
  • Phenylketonuria (PKU)
  • Fatty acid oxidation disorders (including MCAD, LCHAD, VLCAD)
  • Organic acid disorders (including propionic acidemia and isovaleric acidemia)
  • Amino acid disorders (such as tyrosinemia)
  • Urea cycle disorders

What are the symptoms of pediatric metabolism disorders?

Pediatric metabolic disorder symptoms include:

  • Apnea (short periods without breathing)
  • Lethargy (extreme tiredness)
  • Not eating much
  • Tachypnea (unusually fast breathing)
  • Vomiting 

How are pediatric metabolism disorders diagnosed?

Your child's doctor will order tests that can help diagnose metabolic disorders.
