ORAL ALLERGY SYNDROME


Allergic Syndrome

This syndrome is now more commonly called Pollen Food Allergy Syndrome (PFAS) - the term "Oral Allergy" has been adopted to define the symptoms of the syndrome. The Pollen Food Allergy page has more detailed information on why this happens.

Sufferers of Oral Allergy are usually people who already suffer from pollen allergies and seasonal rhinitis and this is due to cross reactivity.

The symptoms of oral allergy syndrome are itchy or swollen lips, gums, tongue and throat. The symptoms should go away with anti histamine. It is usually caused by raw fruit, vegetables, herbs, spices and nuts. If you can eat these foods cooked then you are most likely suffering from Pollen Food Allergy Syndrome as the protein which causes them are denatured by heat.




Key Allergens

The allergens associated with oral allergy are initially a tree or plant pollen and associated with those pollens are various fruits, herbs and vegetables.

Pollens usually associated with Oral Allergy symptoms are alder, birch, grass, mugwort and ragweed pollens.
