Lactose intolerance is a condition caused by a lack of an enzyme called lactase, which, in turn, causes the body to be unable to digest lactose, a sugar found in milk and milk products.actase is normally produced by cells lining the small intestine where it breaks down lactose into a form that can be absorbed by the blood.
