About Oral Allergy Syndrome

oral allergy syndrome



Oral allergy syndrome is a type of food allergy that causes an itching, allergic reaction to the lips, mouth, tongue, and throat when eating uncooked fruits, vegetables, and nuts. Oral allergy syndrome is different from typical food allergies because it is actually a cross-reaction rather than a reaction to the food itself.
An oral allergy syndrome cross-reaction is when the body can’t tell the difference between a pollen protein or an uncooked food protein (such as fruits, vegetables or nuts) so it reacts to the food like it is pollen.

Who is affected?

Oral allergy syndrome is usually seen in older children, teenagers, and adults who also suffer from hay fever or seasonal allergies, though not everyone that has hay fever will suffer from oral allergy syndrome. Oral allergy syndrome symptoms tend to develop over time after eating the trigger food for many years without reactions. There are various foods that have cross-reactions with pollen but a person with oral allergy syndrome may only react to one, several, or no particular food.

When does it occur?

Oral allergy syndrome can occur anytime of the year but it usually worsens during your trigger pollen season. Other times of the year you may have little to no problems eating uncooked fruits, vegetables, or nuts.

Does oral allergy syndrome go by another name?

You may recognize the symptoms of oral allergy syndrome but have never heard of it before. That may be because you know it by another name. Here is a list of the phrases and names that you may recognize:

  • Fruit allergies
