A metabolic disorder can happen when abnormal chemical reactions in the body alter the normal metabolic process.[1] It can also be defined as inherited single gene anomaly, most of which are autosomal recessive.[2]

Symptoms[edit]

Some of the possible symptoms that can occur with metabolic disorders are: lethargy, weight loss, jaundice, seizures, to name a few. This would be indicative that the disorder was not detected upon initial screening, further the symptoms expressed would vary with the type of metabolic disorder.[medical citation needed]

Causes[edit]

Protein involved in Iron metabolism disorder (HFE)

Inherited metabolic disorders are one cause of metabolic disorders, and occur when a defective gene causes an enzyme deficiency.[3] These diseases, of which there are many subtypes, are known as inborn errors of metabolism.[4] Metabolic diseases can also occur when the liver or pancreas do not function properly.[1]

Types[edit]

The principal classes of metabolic disorders are:[5]

Diagnosis[edit]

Metabolic disorders can be present at birth, and many can be identified by routine screening. If a metabolic disorder is not identified early, then it may be diagnosed later in life, when symptoms appear. Specific blood and DNA tests can be done to diagnose genetic metabolic disorders.[6]

The gut microbiota, which is a population of microorganisms that live in the human digestive system, also has an important part in metabolism and generally has a positive function for its host. In terms of pathophysiological/mechanism interactions, an abnormal gut microbioma can play a role in metabolic disorder related obesity.[7]

Management[edit]

Metabolic disorders can be treatable by nutrition management, especially if detected early. It is important for dieticians to have knowledge of the genotype to therefore create a treatment that will be more effective for the individual.[8]
