What is lactose intolerance?
Lactose intolerance is a common digestive condition resulting from the inability to digest lactose, a type of sugar found mainly in milk and dairy products. This inability is due to a deficiency in lactase, the enzyme responsible for breaking down lactose into glucose and galactose, which are easily absorbed by the small intestine.
How is lactose intolerance diagnosed?
Lactose intolerance can be diagnosed by a number of methods. The most common tests include the hydrogen breath test, the lactose tolerance test, and the stool acidity test for infants and young children. These tests help determine how your body reacts to lactose consumption.

Can lactose intolerance be treated?
Although there is no treatment to restore the body's ability to produce lactase, symptoms can be managed by modifying one's diet. Avoiding dairy products or choosing lactose-free products are common options. Lactase supplements are also available, enabling lactose to be digested more efficiently.
