Fruit Allergy Symptoms

A fruit allergy, also known as Oral Allergy Syndrome (OAS), can cause a range of symptoms, including:

• Itchy mouth [1]
• Scratchy throat [2]
• Swelling in and around the mouth and throat [3]
• Hives [4]
• Anaphylaxis (a severe, life-threatening allergic reaction) [5]

These symptoms can occur after consuming certain fruits or vegetables that have similar proteins to certain pollens. For example, people with pollen allergies to trees, grasses, and weeds may develop OAS symptoms when they eat botanically related fruits and vegetables [6].

Some common symptoms of fruit allergy include:

• Tingling or itching sensation in the mouth and throat
• Swelling of the lips, tongue, and throat
• Hives or itchy skin rashes

If you experience any of these symptoms after consuming a particular fruit or vegetable, it's essential to seek medical attention. A healthcare professional can diagnose a fruit allergy through a combination of physical examination, medical history, and laboratory tests [7].

In some cases, a fruit allergy may be mistaken for other conditions, such as oral thrush or mouth ulcers. However, if you suspect that you have a fruit allergy, it's crucial to consult with a healthcare professional for proper diagnosis and treatment.

Common Signs and Symptoms of Fruit Allergy

Fruit allergies can manifest in various ways, ranging from mild discomfort to severe and life-threatening reactions. Here are some common signs and symptoms:

• Itching or tingling of the mouth and throat: This is often the most immediate symptom after consuming raw fruits or vegetables (1, 5, 7).
• Swelling of the face, lip, tongue, and throat: In some cases, people may experience swelling in these areas, which can be accompanied by itching or burning sensations (9, 10).
• Nausea: Some individuals may feel queasy or experience nausea after consuming fruits that trigger an allergic reaction (11).
• **Hives or a rash

Diagnosing Fruit Allergy

Fruit allergies can be diagnosed through various tests, which help determine if you are allergic to specific fruits. Here are some common diagnostic tests for fruit allergy:

• Skin Prick Test (SPT): This test measures the presence of IgE antibodies for the suspect food. SPTs are commonly used to diagnose fruit allergies and involve pricking the skin with a small amount of the suspected allergen.
• Blood Tests: Blood tests can measure the levels of IgE antibodies in your blood, which can indicate an allergy to specific fruits.
• Elimination Diet: This involves removing suspected fruits from your diet for a period and then reintroducing them one by one to monitor for any allergic reactions.

Tests for Specific Fruits

Some diagnostic tests are specifically designed to test for allergies to certain fruits. For example:

• The IgE allergy test panel uses a blood sample to determine if you are allergic to common fruits like Apple, Banana, Grape, Peach, and Pear.
• A skin prick test or blood test can be used to diagnose an allergy to specific pollen, which is often associated with fruit allergies.

Treatment Options for Fruit Allergy

Fruit allergy can be managed through various treatment options, which may include:

• Antihistamines: For minor allergic reactions, antihistamines such as diphenhydramine (Benadryl) and fexofenadine (Allegra) can help alleviate symptoms like itching, watery eyes, and scratchy throat [1][8].
• Epinephrine: In case of a severe allergic reaction or anaphylaxis, epinephrine is the recommended treatment. Your allergist may also recommend food allergy oral immunotherapy (OIT) for long-term management [5].

Immunotherapy

Research suggests that immunotherapy, specifically food allergy oral immunotherapy (OIT), can be a possible long-term treatment for fruit allergies. This process involves gradually increasing doses of the allergenic food to build tolerance [6]. However, it's essential to consult with your physician before starting any form of immunotherapy.

Other Considerations

• Allergy Shots: Some studies have shown that allergy shots can improve symptoms of Oral Allergy Syndrome (OAS), which is caused by cross-reactivity between proteins in fresh fruits and pollens [3].
• Prescribed Antihistamines: For minor allergic reactions, prescribed antihistamines or those available without a prescription may help reduce symptoms [1].

Please consult with your physician to determine the best course of treatment for your specific fruit allergy.

Differential Diagnoses for Fruit Allergy

Fruit allergy can be challenging to diagnose, and it's essential to consider other conditions that may present with similar symptoms. Here are some differential diagnoses to consider:

• Acute Gastritis: Inflammation of the stomach lining can cause symptoms like nausea, vomiting, and abdominal pain, which may be mistaken for a fruit allergy.
• Acute Urticaria: Hives or itchy skin can be caused by various factors, including allergies, infections, or medications. If not properly diagnosed, acute urticaria might be confused with an allergic reaction to fruits.
• Bacterial Gastroenteritis: Food poisoning from bacteria like Salmonella or E. coli can cause symptoms like diarrhea, vomiting, and stomach cramps, which may resemble a fruit allergy.
• Bulimia Nervosa: This eating disorder can lead to digestive issues, including nausea, vomiting, and abdominal pain, making it difficult to distinguish from a fruit allergy.
• Celiac Disease (Sprue): An autoimmune reaction to gluten can cause symptoms like diarrhea, abdominal pain, and fatigue, which may be mistaken for a fruit allergy.
• Chronic Gastritis: Long-term inflammation of the stomach lining can lead to persistent symptoms like heartburn, bloating, and abdominal pain, potentially confusing it with a fruit allergy.

These conditions should be ruled out through proper medical evaluation and testing before diagnosing a fruit allergy. A comprehensive medical history assessment, complemented by objective confirmation of sensitization through either skin tests or blood tests, is crucial for an accurate diagnosis (8)[10].
