Name Lactose Intolerance
Synonyms Alactasia | Dairy Product Intolerance | Hypolactasia | Intolerance, Lactose | Lactose Malabsorption | Malabsorption, Lactose | Milk Sugar Intolerance
Definition The condition resulting from the absence or deficiency of LACTASE in the MUCOSA cells of the GASTROINTESTINAL TRACT, and the inability to break down LACTOSE in milk for ABSORPTION.
