What Triggers Your Citrus Allergy?

According to a new study conducted in Canada, people with an allergy to one species of citrus fruit may be tolerant to other types, despite the fact that these fruits are related genetically. Besides, if you have a negative test for one species of citrus, you may still be allergic to others. These findings mean that the nature of citrus allergy is more complicated that you may have thought.

 

Why Should You Test for Each Type of Citrus Fruit?

 

Many allergists believe that testing for orange is enough to exclude allergies to other types of citrus. However, negative tests for orange allergy don’t rule out other citrus allergies. If you notice abnormal allergy-like symptoms after eating citrus fruit, try to be specific about the type of the fruit when talking to your allergist. You can help your doctor to make a proper diagnosis, if you actually bring the fruit in.

A case of a woman who reported an allergic reaction after eating clementine was described in the Annals of Allergy, Asthma and Immunology. Apart from having oral allergy syndrome, the woman had a history of clementine-caused anaphylaxis. When the patient was tested for fresh clementine and other citrus fruits, the results confirmed that she was allergic specifically to clementine.

Experts conclude: citrus fruits are not interchangeable when it comes to triggering allergies. Instead, allergic reactions, even to closely related foods, can vary from person to person.

Specialists recommend that allergists use an individual approach to each case. When it is difficult to diagnose an allergy correctly, it is especially important to listen to the patient very carefully.

Can OAS Cause Anaphylaxis?

 

If you have pollen allergy and oral allergy syndrome, there is a low risk of an anaphylactic reaction to raw fruits. In case you notice any symptoms after eating a fruit, make sure to seek medical attention.

The symptoms of a systemic reaction may include difficulty swallowing, breath shortness, change in voice, and light-headedness. If you had a history of anaphylaxis, your doctor will likely suggest that you carry an epinephrine auto-injector with you all the time.
