How might galactosemia be treated?

When treatment starts before a baby is 10 days old, there is a much better chance for normal growth, development and intelligence.[1] Affected individuals must avoid all milk, milk-containing products (including dry milk), and other foods that contain galactose for life. It is essential to read product labels and be an informed consumer. Infants can be fed with soy formula, meat-based formula or Nutramigen (a protein hydrolysate formula), or another lactose-free formula. Calcium supplements are also recommended.[2] 

Because the body also makes some galactose, symptoms cannot be completely avoided by removing all lactose and galactose from the diet.  Researchers are working on finding a treatment to lower the amount of galactose made by the body, but there is no effective method to do so at this time.[1]

The Screening, Technology, and Research in Genetics (STAR-G) Project is a US-based organization that provides information on newborn screening. They provide comprehensive information for treatment on galactosemia. To view this information, click here.
