Lactose intolerance is a common digestive condition in which the small intestine doesn’t make enough of the enzyme lactase, which your body needs to break down lactose, the sugar found in milk and other dairy products. Without enough lactase, undigested lactose moves into the colon, where bacteria ferment it and produce gas and acids that can cause bloating, gas, diarrhea, cramps, nausea and other discomfort after eating dairy. The condition affects a large portion of people worldwide, including many in Canada, and symptoms can vary in severity from person to person. Management usually involves reducing or avoiding high-lactose foods, choosing lactose-free alternatives, or using enzyme supplements to help digest lactose, while ensuring adequate calcium and vitamin D intake from other sources.
