Galactosemia

Galactosemia is a disease caused by elevated levels of galactose (a sugar found in dairy products) in the blood resulting from a deficiency of the liver enzyme required for it to be broken down in the digestive tract.

what is galactosemia?

Galactosemia is a rare inherited disease found in infants. It is caused by elevated levels of galactose in the blood due to a deficiency in an enzyme responsible for breaking down galactose. Galactose buildup results in accumulation of toxic compounds that build up in tissues and can lead to complications such as cirrhosis (liver scarring) if not diagnosed early.

fast facts

  • Galactosemia is more likely to occur in people of Irish decent.
  • Galactosemia affects approximately 1 in every 30, 000 to 60, 000 individuals.
  • There are four types of galactosemia (type 1, 2, 3, 4) which are categorized based on which galactose digestive enzyme is altered.

symptoms

Usually there are no symptoms of galactosemia at birth, but symptoms develop shortly after. Some common symptoms of galactosemia include:

  • Jaundice (yellowing of the skin and whites of the eyes)
  • Diarrhea and vomiting
  • Enlargement of the liver
  • Difficulties gaining weight
  • Difficulties with speech and motor skills

lifestyle impacts

Galactosemia is a rare condition that could lead to significant lifestyle impacts if left untreated. Individuals with galactosemia may experience difficulties with communication and speech leading to social isolation, depression, and anxiety. Patients may also experience difficulties with short and long-term memory. Although uncommon, some individuals with galactosemia may also experience seizures.

what can I do?

prevention

Since galactosemia is a rare genetic disorder, this disease cannot be prevented.

diagnosis

Majority of infants are diagnosed within the first week after birth through standard newborn blood tests.

treatment

Patients with galactosemia are unable to digest foods that contain lactose and galactose. There currently is no treatment to substitute for missing galactose digestive enzymes but a strict exclusion of lactose and galactose from a patient’s diet will help manage their condition. With a proper diet and regular care, individuals with galactosemia will likely live normal lives.

additional resources

Here are a few questions to ask your doctor or medical team:

  • What type of galactosemia do I have (type 1, 2, 3, or 4)?
  • Is there a specific diet I should follow to manage my condition?
  • What is the status of my liver? Do I have liver damage?
