Seek emergency medical care for a newborn who is difficult to wake, has trouble breathing, appears pale or mottled, has a seizure, or is not responding normally.
If a baby with suspected or confirmed galactosemia becomes unwell, contact the metabolic team or emergency service using the baby’s emergency care plan.
A newborn needs urgent same-day assessment for jaundice, repeated vomiting, poor feeding, unusual sleepiness, fever, or signs of dehydration.
This is especially important after a positive newborn screening result or when galactosemia runs in the family.
Do not wait for a routine appointment.
Contact the metabolic team promptly after a significant feeding or dietary error, especially in an infant, or if prescribed formula is unavailable.
Arrange routine assessment for slow growth, speech or school difficulties, tremor, balance problems, bone pain, delayed puberty, irregular or absent periods, or difficulty following the dietary plan.
Every sign above is quoted from the sofidex article on Galactosemia. If you are not sure, err upward — it is always reasonable to be checked.
