Oral Allergy Syndrome: What You Should Know

 


Do you feel a tingling, itchy, or burning sensation in your mouth after eating certain raw fruits or vegetables? If so, you might be experiencing Oral Allergy Syndrome (OAS) — a mild but bothersome allergic reaction triggered by your immune system.

OAS typically affects people who have seasonal pollen allergies. That’s because proteins in some raw fruits and vegetables resemble pollen proteins. The immune system mistakes them for allergens, leading to reactions such as itching in the lips, throat, and even the ear canal. It’s most common in teens and adults and, thankfully, symptoms are usually mild and short-lived.

Is OAS Serious?

In most cases, no. OAS is more annoying than dangerous. However, if you experience severe symptoms like difficulty breathing, swelling of the throat, or low blood pressure — especially after eating nuts or seeds — seek emergency care immediately.

Common Trigger Foods

Different pollens react with different foods:

  • Ragweed allergy: Banana, cucumber, watermelon, honeydew, sunflower seeds

  • Birch allergy: Apple, celery, carrots, cherries, kiwi, peach, coriander

  • Grass allergy: Oranges, tomatoes

  • Mugwort allergy: Apple, celery, carrots, broccoli, cabbage, bell pepper, black pepper, peanuts

Diagnosing and Managing OAS

Doctors usually confirm OAS with a skin prick test and dietary history. Once diagnosed, managing it is straightforward:

  • Avoid the raw versions of trigger foods.

  • Cook, peel, or pressure-cook fruits and vegetables — heat breaks down the proteins causing the reaction.

  • Antihistamines may help reduce symptoms.

  • In more persistent cases, immunotherapy may be recommended.

Prevention Tips

Eliminating or modifying trigger foods can prevent most symptoms. Cooking or peeling often makes them tolerable. But in severe cases, it's safer to avoid them entirely — even dishes prepared with them.

Final Note

Oral Allergy Syndrome isn’t life-threatening for most, but it can disrupt your diet and comfort. Recognize your triggers and adjust how you eat certain fruits and vegetables. For guidance on managing OAS and related allergies, consult with your allergist or visit Surya Dental Care for expert advice.
