Lactose is the predominant sugar found in milk and milk products. People with Lactose intolerance (LI) cannot properly digest lactose because they lack or are deficient in the enzyme, lactase, which is key to the digestion of lactose. Lactose is a complex sugar made up of two different sugar molecules (disaccharide), galactose and glucose, each of which is a simple (monosaccharide) sugar and more readily absorbed in the body's stomach and intestine and processed in other organs.
LI is common among adults in the United States and elsewhere. It is worrisome and uncomfortable but not at all dangerous.
This disorder is an inborn error of carbohydrate metabolism characterized by the impaired ability to absorb nutrients from the small intestine (malabsorption syndrome).
