What is Galactosemia?

What is Galactosemia?

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.

Symptoms of galactosemia are:
  • Convulsions.
  • Irritability.
  • Lethargy.
  • Poor feeding — baby refuses to eat formula containing milk.
  • Poor weight gain.
  • Yellow skin and whites of the eyes (jaundice)
  • Vomiting.

What is the cause of galactosemia?

Galactosemia occurs due to disruptions or changes (mutations) in the GALT gene resulting in deficiency of the GALT enzyme. This leads to abnormal accumulation of galactose-related chemicals in various organs of the body causes the signs and symptoms and physical findings of galactosemia.

What is the difference between lactose and galactose?

Galactose is a sugar that may be found alone in foods but is usually found as part of another sugar called lactose. Lactose is sometimes called milk sugar and is made of equal parts of simple sugars galactose and glucose.

Galactosemia should not be confused with cow’s milk allergy or lactose intolerance. Cow’s milk allergy is among the more common food allergies. Symptoms include fussiness, gassiness, and diarrhea.

Is there a cure for galactosemia?

Without treatment, most affected newborns do not survive. Typically diagnosed in newborn screening tests, galactosemia can be treated only by entirely removing lactose and galactose from the diet. There is no cure yet.

How common is galactosemia?

Frequency. Classic galactosemia occurs in 1 in 30,000 to 60,000 newborns. Galactosemia type II and type III are less common; type II probably affects fewer than 1 in 100,000 newborns and type III appears to be very rare.

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 fruits and vegetables have galactose?

Galactose contents ranged from less than 0.1 mg per 100 g of tissue in artichoke, mushroom, olive, and peanut to 35.4 mg per 100 g in persimmon. Fruits and vegetables with over 10 mg per 100 g included date, papaya, bell pepper, tomato and watermelon.

Does yogurt contain galactose?

Yogurt is an autodigestive source of lactose and contains free galactose (5 g/100 g) (Dewit et al. 1988). Ever since, yogurt is manufactured from Gal?S.

Where is lactose found in nature?

Lactose is found in milk from mammals: from human breastmilk to cow’s milk and every kind of milk in between. Since lactose is found in milk, it’s also naturally present in a variety of milk-derived dairy products, though the amount of it varies by the method of production and processing.

Does lactose free milk contain galactose?

Lactose is made up of two sugars called glucose and galactose which will still be present in the product. Although it is lactose free, the galactose levels are still very high in the product.

How do you test for galactosemia?

Which laboratory tests are used to diagnose classic galactosemia? If classic galactosemia is suspected based on symptoms, family history, or newborn screen results, measurement of GALT enzyme activity in red blood cells and DNA analysis for GALT gene variants are recommended to confirm diagnosis.

What body parts does galactosemia affect?

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.

Two recent publications reported that small amounts of galactose are present in many fruits and vegetables. We report the presence of considerable amounts of free galactose in some legumes (dried beans and peas) and the presence of bound galactose in many food plants.

Does milk contain galactose?

It is important to know that galactose is present not only in milk but in other sources of food. A strict galactose-free diet in galactosemic patients with transferase deficiency is not harmful.

Where can I get galactose?

Galactose is found in dairy products, avocados, sugar beets, other gums and mucilages. It is also synthesized by the body, where it forms part of glycolipids and glycoproteins in several tissues; and is a by-product from the third-generation ethanol production process (from macroalgae).

What are the symptoms of glucose galactose malabsorption?

Symptoms include abdominal pain, unpredictable bowel movements, variation in stool consistency, bloating, passing gas (flatulence), nausea, headache, fatigue, depression, anxiety and difficulty concentrating. Lactose intolerance is a condition characterized by an inability to break down the sugar in milk (lactose).

If you or your dependent(s) are diagnosed with Classic Galactosemia and experience any of these symptoms, you may be eligible for disability benefits from the U.S. Social Security Administration.

How does galactosemia cause mental retardation?

The mental retardation that is sometimes observed in galactosemic children may be caused by the high galactose level, the low glucose level, or both. It has been estimated that hereditary intolerance to galactose occurs in approximately one in 18,000 infants.

How does galactosemia affect the liver?

Galactosemia means too much galactose builds up in the blood. This accumulation of galactose can cause serious complications such as an enlarged liver, kidney failure, cataracts in the eyes or brain damage. If untreated, as many as 75% of infants with galactosemia will die.
