Children growing up with phenylketonuria (PKU) need to incorporate health care into their normal routines. Read about encouraging proper development.

Key points

  • Babies and young children are learning new things every day. Encourage your child's development by playing with them and teaching them.
  • As your child grows older, they can learn to do more things for themselves. Give them simple chores to do and encourage them to learn new things.
  • Set up a routine for PKU care, and start teaching your child about "green light" or "go" foods.

What is phenylketonuria (PKU)?

Phenylketonuria (PKU) is an absence or deficiency in phenylalanine hydroxylase (PAH), an enzyme involved in metabolizing or converting the amino acid phenylalanine into tyrosine, another amino acid. PAH deficiency results in high levels of blood phenylalanine and an accumulation of phenylketones in the urine.

Partial deficiency of the enzyme results in hyperphenylalaninemia. In this condition, the child has elevated blood phenylalanine, although it is not quite as high as when there is a complete absence of PAH. In hyperphenylalaninemia, phenylketones do not accumulate.

Transition through the years

Children go through many changes as they grow up, including how they think, what they like, and how they take care of themselves. Big changes are often called transitions.

A child must go through a transition in health care when they are diagnosed with PKU. The family and the health care team can help them learn good health care habits, the same way they help them learn other life skills. A child who learns good health care habits will probably have good health habits and attitudes all their life.

This page will help you think about age-appropriate goals for your child. It will give you ideas to help your child become more confident and independent in life and in their health care. It also includes extra goals for children with PKU.

Each child has different abilities from other children. Your child may surprise you with what they can do. Expect good things from your child and encourage them to expect the best from themselves.
