1. Lactose intolerance
Lactose intolerance is the inability to digest lactose (a disaccharide of glucose and galactose ). The digestion of lactose requires the enzyme lactase. Undigested lactose causes two major problems: * fermentation of lactose by intestinal bacteria produces gas and organic acid * lactose causes an osmotic diarrhea in the large bowel

2. Lactose intolerance
Lactose intolerance is the inability to digest significant amounts of lactose , the predominant sugar of milk. This inability results from a shortage of the enzyme lactase, which is normally produced by the cell s that line the small intestine. Lactase breaks down milk sugar into simpler forms that can then be absorbed into the bloodstream. When there is not enough lactase to digest the amount of lactose consumed, the results, although not usually dangerous, may be very distressing. While not all persons deficient in lactase have symptoms, those who do are considered to be lactose intolerant. Common symptoms include nausea, cramps, bloating, gas, and diarrhea, which begin about 30 minutes to 2 hours after eating or drinking foods containing lactose. The severity of symptoms varies depending on the amount of lactose each individual can tolerate.

3. Lactose intolerance
A genetic trait characterized by the absence of the enzyme lactase, which breaks down lactose, the main sugar in milk and other dairy products.
