Many patients are often confused about allergy to food and food intoloerance. Especially this is common with milk allergy and milk intolerance due to deficiency of an enzyme needed to digest milk. When call it allergy it means that we can demonstrate an IgE that our immune system produce to fight a food. When we call it intolerance, it means food does not agree but there is no evidence of an allergy. This is true for symptoms to wheat also. The common symptoms of lactose intolerance and wheat intolerance would be diarrhea and abdominal cramps, and blotting. Lactose intolerance induces the symptoms starting a few hours after ingestion. Wheat intolerance is a vague term, in the absence of wheat allergy (lack of IgE to wheat), can present similarly, while wheat allergy can induce symptoms of anaphylaxis with a rapid onset of symptoms.
