What are the signs and symptoms of galactosemia?
Symptoms of galactosemia are:
- Poor feeding — baby refuses to eat formula containing milk.
- Poor weight gain.
- Yellow skin and whites of the eyes (jaundice)
What does galactosemia mean?
Galactosemia is a disorder that affects how the body processes a simple sugar called galactose. A small amount of galactose is present in many foods. It is primarily part of a larger sugar called lactose, which is found in all dairy products and many baby formulas.
What are the effects of galactosemia?
Some of the organs that may be affected include the brain, eyes, liver, and kidneys. Infants with galactosemia usually have diarrhea and vomiting within a few days of drinking milk or formula containing lactose. Some of the other early effects of untreated galactosemia include: Failure to gain weight or grow in length.
What does galactosemia look like?
Your baby first loses their appetite and starts vomiting. Then they get jaundice, a yellowing of the skin and the whites of their eyes. Diarrhea is common, too. The disease leads to severe weight loss and your baby struggles to grow and thrive.
How is galactosemia treated?
How is galactosemia treated? The only treatment for galactosemia is avoiding foods that contain lactose and galactose. A physician and a dietitian who specializes in metabolic disorders can tell you what modified dietary plan your child will need to follow.
How do you confirm galactosemia?
Genetic testing for galactosemia can be performed on a CVS or amniotic fluid sample. This test evaluates the likeliness that the disorder is present in a fetus. Genetic testing is employed after birth to determine the exact type of GALT gene mutation in an infant who has a confirmed GALT enzyme deficiency.
Excess galactose in the blood affects many parts of the body. Some of the organs that may be affected include the brain, eyes, liver, and kidneys. Infants with galactosemia usually have diarrhea and vomiting within a few days of drinking milk or formula containing lactose.
How do you know if your baby has galactosemia?
A baby may develop signs of galactosemia within the first few days of life if the consume lactose found in breast milk or baby formula. These initial signs include: Refusal to eat. Spitting up or vomiting.
The most common treatment for galactosemia is a low-galactose diet. This means that milk and other foods that contain lactose or galactose can’t be consumed. There is no cure for galactosemia or approved medication to replace the enzymes.
Can galactosemia be cured?
There is no cure for galactosemia or approved medication to replace the enzymes. Although a low-galactose diet can prevent or reduce the risk of some complications, it may not stop all of them. In some cases, children still develop problems such as speech delays, learning disabilities, and reproductive issues.
Is galactosemia the same as lactose intolerance?
Is galactosemia the same as lactose or milk intolerance? No, galactosemia should not be confused with lactose intolerance. People with galactosemia usually have no problems digesting lactose or absorbing galactose. The problems occur after galactose has entered the blood stream.
What is the life expectancy of someone with galactosemia?
With a galactose-restricted diet patients have a normal life expectancy. However, patients may still suffer long-term complications such as problems of mental development, disorders of speech, hypergonadotrophic hypogonadism and decreased bone mineral density (Bosch 2006).
What happens if galactosemia is untreated?
A. Untreated galactosemia can cause rapid, unexpected death due to an infection that invades the blood. Infants with untreated galactosemia may also develop brain damage, liver disease, and cataracts. Each child with galactosemia is different so the outcome will not be the same for all children.
What do you need to know about galactosemia?
Biliary Atresia Galactosemia is an inherited disorder that prevents a person from processing the sugar galactose, which is found in many foods. Galactose also exists as part of another sugar, lactose, found in all dairy products.
What does galactose in the blood mean in medical terms?
Galactosaemia is a genetic condition that affects the body’s ability to process galactose. Galactose is a naturally occurring sugar found in a number of human organs and other living things. It is also a part of lactose, the main sugar found in animal milks. The literal meaning of galactosaemia is “galactose in the blood”.
How often does galactosemia occur in Irish people?
An increased frequency of Galactosemia occurs in individuals of Irish ancestry. Classic Galactosemia occurs in 1 in 30,000 to 60,000 newborns. Galactosemia is an inherited disorder that prevents a person from processing the sugar galactose, which is found in many foods.
How is galactosemia related to lactose intolerance?
Galactosemia is an inherited disorder that prevents a person from processing the sugar galactose, which is found in many foods. Galactose also exists as part of another sugar, lactose, found in all dairy products.
What effect does galactosemia have on the body?
Galactosemia affects the body by preventing it from breaking down galactose, a simple sugar found in lactose. If a person continues to ingest galactose, they will experience a toxic build-up that can cause cataracts and brain, liver, or kidney damage. Untreated galactosemia can also cause a person’s white blood cells to stop working properly, leaving them susceptible to serious infections.
How are you diagnosed with galactosemia?
Galactosemia is usually diagnosed though tests that are done as part of newborn screening programs. A blood test will detect high levels of galactose and low levels of enzyme activity. The blood is usually taken by pricking a baby’s heel. A urine test may also be used to diagnose this condition.
What is the difference between glucose and galactose?
The main difference between glucose and galactose is the chemical structure; the position of each –OH group present in both molecules. This difference occurs in the 4 th carbon atom . The following image shows this in detail.
Is galactosemia be cured?
Galactosemia is a disease that cannot be cured. The disease can only be managed in order to help prevent complications of the condition. The only way to manage galactosemia is to eliminate lactose and galactose from the diet completely.
