Glucose-galactose malabsorption

Glucose-galactose malabsorption is a rare condition in which the cells lining the intestine cannot take in the sugars glucose and galactose, which prevents proper digestion of these molecules and of the larger molecules made from them. Glucose and galactose are simple sugars, or monosaccharides. Sucrose and lactose are disaccharides made from two simple sugars and are broken down during digestion, sucrose into glucose and fructose and lactose into glucose and galactose. As a result, lactose, sucrose and other compounds made from carbohydrates cannot be digested by individuals with this condition. The source article lead does not state its cause, symptoms or treatment, so those are left for a later depth pass.
