Lactose Intolerance

Definition

Lactose intolerance is a digestive condition where the body cannot properly digest lactose, a type of sugar found in milk and dairy products.

Scientific / Technical Definition

Lactose intolerance occurs when there is a deficiency of lactase, an enzyme produced in the small intestine that is necessary for the breakdown of lactose into glucose and galactose. As a result, undigested lactose reaches the colon, where it is fermented by bacteria, leading to symptoms such as bloating, diarrhea, and gas.
