• Overview

    Lactose is the sugar in milk products. Individuals who are lactose intolerant lack the enzyme or chemical (lactase) to break down this sugar for absorption. As a result, lactose gets into the large bowel (colon) and may cause gas, bloating, diarrhea and abdominal cramping. Sometimes lactose intolerance occurs after digestive infections.

    Lactose intolerance affects more than 7 million Canadians. This is likely an underestimate as many individuals do not associate their symptoms with lactose-containing foods or do not experience symptoms.
