What is the difference between milk allergy and lactose intolerance?
When someone has a milk allergy his/her immune system has an abnormal reaction to milk proteins, which may be life-threatening. When a person is lactose intolerant, his/her body does not have enough of the enzyme lactase, needed by the digestive system, to break down the milk sugar lactose. Symptoms of lactose intolerance include abdominal pain, bloating and diarrhea after milk ingestion. Lactose intolerance is not an allergy. If you are unsure whether you have milk allergy or lactose intolerance, consult an allergist.
