If a child with a metabolic disorder is not treated promptly, the first symptoms often become apparent within a few months of birth. The specific symptoms vary depending on the condition but may include developmental delays, muscle weakness, liver or kidney problems, growth issues, or in severe cases, coma.

General information
A metabolic disorder is a rare hereditary condition in which the body cannot process certain nutrients properly because a specific enzyme is deficient or absent. As a result, essential molecules such as amino acids cannot be broken down correctly, which disrupts the body’s metabolism.
Metabolic disorders are often first identified through newborn screening (the heel-prick test). This initial screening is typically followed by further diagnostic procedures such as blood and urine tests, genetic testing, and measurement of enzyme activity.
Following the results of newborn screening, your paediatrician or GP will contact you and refer you to a hospital that specialises in the management of inherited metabolic disorders. It is important to attend this appointment promptly so a treatment plan can be established. For many of these conditions, a low protein diet is a long-standing and highly effective treatment.
A low protein diet limits protein intake and is supplemented with specially formulated protein substitutes to ensure the body receives the other essential amino acids it needs. Following this diet closely is crucial for maintaining good health and preventing complications.
Diet and nutrition
On a low protein diet, it is important to avoid protein-rich foods such as meat, fish, dairy, nuts, and legumes. Suitable options include most fruits, vegetables, and specially formulated low-protein products.
Planning meals in advance can help make it easier to stay on track. Seek ongoing support from your dietitian, family, friends, and patient support groups.
