Lactose Intolerance Directory
Lactose intolerance is the inability to digest lactose, the sugar primarily found in milk and dairy products such as ice cream and cheese. It is caused by a shortage in the body of lactase, an enzyme produced by the small intestine that is needed to digest lactose. Symptoms include nausea, cramps, painful gas, bloating, and diarrhea. Lactose intolerance is diagnosed based on relief of symptoms when avoiding dairy products. Other tests include a hydrogen breath test, a blood glucose test, and a stool acidity test. Lactose intolerance is primarily treated by eating lactose-containing foods that don't produce symptoms.
