What are the symptoms of metabolic disorders?

Metabolic disorders can have a variety of symptoms depending on the type of disorder. Some, like type 2 diabetes, come on later in life, but many are genetic, meaning they are inherited. In many cases, inherited metabolic disorders are found during routine tests done when a baby is born, so the disorder is treated before symptoms develop. If the disorder is not noticed early, symptoms usually develop early in childhood. These symptoms may include seizures, stunted growth, developmental delays, and other physical or mental disabilities. Many metabolic disorders have symptoms similar to those of conditions such as cerebral palsy and autism. Noninherited metabolic disorders may have a variety of symptoms, including fatigue, heart problems, eye problems, and depression.
