Hi, I’m Dr. Hamsa Subramanian – I’m an allergist. Food allergies are increasing. Many patients come to see me because their mouth itches they have throat itching or tongue itching when they eat fresh fruits and vegetables. Sometimes this is not a true food allergy it is what we call Oral Allergy Syndrome and that’s because many of these patients are allergic to tree grass, or even ragweed pollen allergy and it is a cross-reaction between certain fresh fruits and vegetables. So to start off evaluating a patient with oral allergy syndrome a good history is done this is followed by an allergy skin test and sometimes it is also followed by a blood test. Talk to your allergist or come in for a consultation. We can discuss about this in detail.
