Galactosemia Detailed Information
Posted on October 6, 2008
Galactosemia is also very common in the Irish Traveller population. This is attributed to consanguinity within a relatively small gene pool.
Galactosemia is the lack of ability of the body to employ (metabolize) the simple sugar galactose, causing the buildup of galactose 1-phosphate in the body. It arises in about 1 out of every 60,000 births among Caucasians, while the rate is dissimilar for other groups. There are three forms of the disease include galactose-1 phosphate uridyl transferase lack (classic galactosemia, the most common and most severe form), deficiency of galactose kinase, and deficiency of galactose-6-phosphate epimerase. People with galactosemia are unable to completely break down the simple sugar galactose.
Galactose makes up half of lactose, the sugar initiate in milk. Lactose is called a disaccharide because it is made up of two sugars, galactose and glucose, bound together. It is much rarer in Japan and much more general in Italy, expressly the traveler region. Galactosemia usually causes no symptoms at birth, but jaundice, diarrhea, and vomiting soon develop and the baby fails to increase weight.
If not sensed instantly, it results in liver disease, cataracts, mental retardation, and even death. Death can arise as early as one to two weeks of age from harsh escherichia (E. coli) bacteria infections. E. coli infections are general in untreated galactosemic children. All infants who expand jaundice are considered for galactosemia. Other grave complications of this condition can comprise overwhelming bacterial infections (sepsis) and shock. Affected children are also at augmented risk of delayed development, clouding of the lens of the eye (cataract), speech difficulties, and mental retardation.
Females with common galactosemia may experience reproductive problems caused by ovarian failure. The main aim of dietary treatment of galactosemia is to eliminate any foods including galactose from the diet. The condition is lifelong and requires abstinence from milk, milk products, and galactose-containing foods for life. Calcium supplements are suggested. Pills that utilize lactose as filler must also be avoided. Soy-based and casein hydrolysate-based formulas are recommended for infants with galactosemia. Parents require taking care and teaching the child to avoid not only milk and milk products , but also those foods that hold dry milk products.
