Lactose intolerance can be caused by some diseases of the digestive system and by injuries to the small intestine that result in a decreased production of lactase. While rare, some children are also born unable to produce the enzyme.

Our 13-year-old daughter has developed an intolerance for drinking milk since being on large doses of antibiotics. However, she can eat yogurt and some ice cream. If she takes Lactaid she has occasionally vomited. Why would this happen? And why can she apparently tolerate lactose in some dairy foods but not others?
