Patient's question:
Recently, I noticed that my child has developed intellectual disability, neurological symptoms, eczema, and skin scratch symptoms. When I went to the hospital for a check-up, I was diagnosed with phenylketonuria.Doctor's answer:
Hello, according to your description, it is mainly applicable to typical PKU patients and those with sustained blood phenylalanine levels above 1.22 mmol/L (20 mg/dL). Since phenylalanine is an essential amino acid for protein synthesis, complete deficiency can also lead to neurological damage. Therefore, infants can be fed specially formulated low-phenylalanine formula, and when introducing complementary foods during the toddler stage, it is recommended to focus on low-protein foods such as starches, vegetables, and fruits.
