Signs & symptoms

In classic galactosemia, symptoms first appear within the first days of life and may include weight loss, vomiting, diarrhea, and jaundice. If not treated, complications may include liver and kidney damage, developmental disabilities and problems with motor skills.


Diagnosis may start even before getting pregnant- in genetic screening for both parents. After birth, the newborns go through screening by a blood sample.


Treatment includes a diet without lactose or galactose and a soy-based formula. Also, some fruits and vegetables are cut off the menu as well and vitamins supplements are recommended. Girls may require hormonal treatment starting from puberty.
