If you’re pregnant and have phenylketonuria (PKU), you may have many concerns about how your condition could affect your baby and what adjustments you need to make for a healthy pregnancy. Here’s what you should understand.

What is Phenylketonuria (PKU)?

PKU is a hereditary disorder occurring when the body lacks a specific enzyme that helps break down phenylalanine, an amino acid. During pregnancy, this condition is termed maternal PKU. With careful planning and a commitment to a low-phenylalanine diet, you can have a safe and healthy pregnancy.

What is a Safe Diet for Those with PKU?

If you’re living with maternal PKU, you’re likely familiar with the dietary restrictions that come with it, even if you haven’t strictly followed them recently. The low-phenylalanine diet generally includes a phenylalanine-free medical protein formula to supplement your nutrition while avoiding high-phenylalanine foods. It is crucial to manage your diet effectively to minimize risks to your developing baby.

Risks of Unmanaged Maternal PKU

If maternal PKU is not adequately managed, it can pose significant risks to the baby, including developmental delays and cognitive impairments. Therefore, it’s essential to maintain strict dietary control and regularly consult with health professionals specializing in PKU care.

Monitoring During Pregnancy

Expect to undergo special monitoring throughout your pregnancy if you have PKU. This might involve frequent blood tests to check your phenylalanine levels and ensure that they remain within a safe range for both you and your baby.

Will My Baby Have PKU?

There is a chance that your child could inherit PKU if both parents carry the gene. It’s advisable to discuss this with a genetic counselor to understand your specific risks and options.
