Oral Allergy Syndrome

What is Oral Allergy Syndrome?

Oral allergy syndrome is an allergic reaction to certain proteins in a variety of fruits, vegetables, and nuts. This syndrome occurs in some people with pollen allergies. Symptoms usually affect the mouth and throat. These reactions are not related to pesticides, metals or other substances.
Who is affected and what pollens are involved?

Most people who have oral allergy syndrome also have seasonal allergies (hay fever). Older children and adults are the most likely to have this syndrome. You have a higher risk of this syndrome if you are allergic to the pollens of:

– Birch Tree
– Grass
– Ragweed
– English Plantain (weed)
– Mugwort (sage)

These reactions can occur at any time of the year. However, symptoms may be worse during the pollen season.
What are the symptoms and when do they occur?

Symptoms typically include itching and burning of the lips, mouth and throat. Some people also have watery, itchy eyes, runny nose, and sneezing. Sometimes peeling or touching the foods may result in a rash, itching or swelling where the juice touches the skin. Occasionally, reactions may lead to hives and swelling of the mouth, throat and airway. In rare cases, severe allergic reactions have been reported such as vomiting, diarrhea, asthma, generalized hives, and anaphylactic shock. Symptoms usually develop within minutes of eating, drinking or touching the fresh/raw food. Occasionally, symptoms occur more than an hour later.
