Lactose Intolerance – Its Symptoms And Causes

Lactose intolerance is the inability of the body to digest and absorb a large sugar molecule, contained in milk and dairy products, called lactose.  The body’s digestive system becomes intolerant to milk and products containing milk, which causes gastrointestinal problems and should not be confused with allergic reactions to milk.

In order for lactose to be absorbed, an intestinal enzyme, lactase, splits the lactose molecule into two smaller sugars, galactose and glucose.  Lactase is present in the cells lining the surface of the small intestine.  A deficiency in lactase is the cause of lactose intolerance because lactose cannot be broken down into a form that the intestines can absorb.
