Metabolism refers to the chemical reactions in your body’s cells that change the food we eat into the chemical compounds that keep us alive. A metabolic disorder occurs when abnormal chemical reactions disrupt the normal metabolic processes.

There are many different types of metabolic disorders, but most are very rare. The most common metabolic condition is phenylketonuria (PKU). Other examples include galactosemia, medium chain acyl-coA dehydrogenase deficiency (MCAD), Prader-Willi syndrome and other disorders of fatty acid utilization.

Metabolic disorders can affect the utilization of protein, fat or carbohydrates or a combination of these. Most are inherited genetic conditions. Metabolic disorders are lifelong conditions, but in general, early treatment can alter their natural progression.

If your child has a metabolic disorder, symptoms may appear only a few days after birth, or they could take years to develop (this is rare). Symptoms may not be evident until the body is stressed by illness or fasting.

The symptoms of metabolic disorders may include:

  • Abnormal odor of breath, sweat and urine
  • Somnolence (excessive sleepiness)
  • Developmental delay
  • Failure to thrive (in infants)
  • Jaundice
  • Lethargy
  • Poor appetite
  • Seizures
  • Vomiting

Diagnosis of Metabolic Disorders

Some metabolic conditions are identified within a few days of a child’s birth through newborn screening tests. These tests use a blood sample to check for treatable disorders, including some metabolic, endocrine, hematologic and respiratory disorders that may not be immediately apparent. If your child’s test shows any abnormal results for the metabolic screening, he or she will need to be evaluated by a doctor within five to seven days.

Treatments

Treatments

Most treatable metabolic conditions require special diets to ensure proper health and prevent complications. If your child has a metabolic disorder, he or she may be able to lead a normal, healthy life if diet is carefully controlled.

Treatment options include:

  • Pediatric Genetic Counseling. If your newborn is diagnosed with a metabolic disorder, a genetic counselor can help you understand the condition, its lifelong implications and how it will affect your child as he or she matures.
  • Nutrition. Specialized or restrictive diets are often a key treatment for metabolic disorders.
  • Special formulas. Some metabolic conditions require lifelong use of special formulas. Your child's care team will work with you to access these nutritional sources.
  • Medicine. In addition to diet, patients with certain metabolic conditions may also benefit from medications or specific supplements. Your child's doctor will discuss these options with you and help determine the best course of treatment.
