Glucose-galactose malabsorption is a rare disorder; only a few hundred cases have been identified worldwide. However, as many as 10 percent of the population may have a somewhat reduced capacity for glucose absorption without associated health problems. This condition may be a milder variation of glucose-galactose malabsorption. [2]
Lactose is a disaccharide sugar composed of galactose and glucose that is found in milk. Lactose can not be absorbed by the intestine and needs to be split in the small intestine into galactose and glucose by the enzyme called lactase; unabsorbed lactose can cause abdominal pain, bloating, diarrhea, gas, and nausea.

The only treatment for classic galactosemia is eliminating lactose and galactose from the diet (e.g. exclusion of dairy products containing lactose). [9] [20] [21] Lactose-restricted diet is efficient in resolving acute complications; however, it is not sufficient to prevent long-term complications affecting the brain and female gonads. [20]
Treatment is dependent on the type of glycogen storage disease. Von Gierke disease is typically treated with frequent small meals of carbohydrates and cornstarch, called modified cornstarch therapy, to prevent low blood sugar, while other treatments may include allopurinol and human granulocyte colony stimulating factor.

The development of early cataracts in homozygous affected infants is fully preventable through early diagnosis and treatment with a galactose-restricted diet. Some studies have suggested that, depending on milk consumption later in life, heterozygous carriers of galactokinase deficiency may be prone to presenile cataracts at 20–50 years of age.
After the ingestion of lactose, most commonly from breast milk for an infant or cow milk and any milk from an animal, the enzyme lactase hydrolyzes the sugar into its monosaccharide constituents, glucose and galactose. In the first step of galactose metabolism, galactose is converted to galactose-1-phosphate (Gal-1-P) by the enzyme galactokinase.
They also better help manage blood sugar levels and support heart health. Try using whole wheat bread in place of white bread for your sandwiches, whole wheat pasta instead of regular pasta and ...
After resorption in the gut, the monosaccharides are transported, through the portal vein, to the liver, where all non-glucose monosacharids (fructose, galactose) are transformed into glucose as well. [4] Glucose (blood sugar) is distributed to cells in the tissues, where it is broken down via cellular respiration, or stored as glycogen.
