Lactose Intolerance

Definition

Lactose intolerance is the inability to digest lactose, a sugar found in milk and dairy products, leading to digestive discomfort.

Lactose intolerance occurs when the small intestine does not produce enough of the enzyme lactase, which is necessary for breaking down lactose into glucose and galactose. This results in undigested lactose passing into the large intestine, where it is fermented by bacteria, causing symptoms such as bloating, diarrhea, and gas.
