PKU & Pregnancy – Preconception

The journey to motherhood, when you have Phenylketonuria (PKU), should begin with your metabolic clinic. It is essential to work with your clinic before, during and even after pregnancy. Only your clinic can provide the best guidance to ensure the best outcome for you and your baby. They will work with you to ensure well-controlled blood phenylalanine (PHE) levels prior to pregnancy and throughout your pregnancy to prevent the negative effects of elevated PHE.

Studies in maternal PKU (MPKU) have shown uncontrolled blood PHE levels during pregnancy can cause the following outcomes for the baby:

  • Microcephaly (small head size)
  • Intellectual disability
  • Behavioral issues
  • Congenital heart defects (CHD)
  • Low birth weight and reduced length for age

Keeping your PHE levels within recommended range will help protect your baby from these risks.

Steps to getting PHE levels in the recommended range:

Find low-PHE recipes at medicalfood.com/recipes

Recommit yourself to the low PHE diet

  • Explore vegan recipes with the plant-based protein ingredient omitted (such as nuts, soy, tofu, etc.)
  • Change regular bread, rice and pasta to low protein versions, such as Nutricia’s Loprofin low protein food line

Find a PKU formula you enjoy

  • Nutricia offers the widest range of PKU formula options. You are sure to find one that meets your personal taste and needs. Check out Nutricia’s formula options here.
  • Create a plan and stick to it – this will help to make sure you take all your recommended formula each day at scheduled times.

Make a new routine

  • Regular blood samples (blood spots) will let you know when your PHE levels are in the ‘safe-range’ for pregnancy. Set a reminder on your calendar or cellphone to send your blood spots to your clinic on a regular basis (as instructed by your clinic).
  • Meal planning in advance will help make food shopping and new dining habits easier.
