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

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. There are four categories of symptoms-acute symptoms, late-onset acute symptoms, progressive general symptoms and permanent symptoms.[3]

Causes

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.[4] These diseases, of which there are many subtypes, are known as inborn errors of metabolism.[5] Metabolic diseases can also occur when the liver or pancreas do not function properly.[1]

Types

The principal classes of metabolic disorders are:[6]

Diagnosis

Gut microbiota

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.[7]

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.[8]

Management

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.[9]

Screening

Metabolic disorder screening can be done in newborns via the following methods:[10]
