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]
Glucose-galactose malabsorption occurs when the lining of the intestinal cells cannot take in glucose and galactose which prevents the use of those molecules in catabolism and anabolism. The disease has symptoms that consist of watery and/or acidic diarrhea which is the result of water retention in the intestinal lumen and osmotic loss created ...
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.

Since the diet is low in carbohydrates, the body gets little glucose, normally the main energy source. The fat in the diet is converted by the liver in ketone bodies, which causes a build up of ketones in the blood stream, called ketosis. Ketone bodies are transported across the blood-brain barrier by other means than the GLUT1 protein and thus ...
Foods that should be avoided by people with fructose malabsorption include: Foods and beverages containing greater than 0.5 g fructose in excess of glucose per 100 g and greater than 0.2 g of fructans per serving should be avoided. Foods with >3 g of fructose per serving are termed a 'high fructose load' and possibly present a risk of inducing ...
Even foods that may seem healthier, like dressings, granola bars, and condiments, can be high in added sugar. Ditch alcohol. Alcohol is a significant source of empty calories that can add up quickly.
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.
Worldwide, around 65% of adults are affected by lactose malabsorption. [ 5 ] [ 8 ] Other mammals usually lose the ability to digest lactose after weaning . Lactose intolerance is the ancestral state of all humans before the recent evolution of lactase persistence in some cultures, which extends lactose tolerance into adulthood. [ 9 ]
