Many NICCD patients have been given lactose again after their liver functions have normalized. Re-introducing lactose does not seem to cause any deterioration in the lab results for liver function tests or plasma amino acid tests in these patients. This is a puzzling question, and one that our Foundation is trying to fully understand. You or your child’s attending physician will ultimately decide whether it is appropriate to re-introduce lactose into their diet and if yes, when to do so. However, if patients have galactosemia post-NICCD, lactose should be removed from their diet.
