Tomato allergy: Symptoms, Treatment, Immunotherapy, Tips to avoid

Tomato allergy is relatively rare but can be particularly hazardous to individuals with a sensitivity to grass pollens, as they may experience a cross-reaction to tomatoes. This is due to a condition called Oral Allergy Syndrome (OAS), where the immune system confuses the proteins in tomatoes with grass pollen. Those with latex allergies may also face a higher risk because of the potential for cross-reactivity. Latex-fruit syndrome can result in an allergic response to tomatoes among those with a latex hypersensitivity. In severe cases, a tomato allergy can lead to anaphylaxis, a potentially life-threatening condition that requires immediate medical attention. Symptoms of a tomato allergy can include hives, itching, or eczema; gastrointestinal distress like vomiting or diarrhea; respiratory issues; and at its most extreme, anaphylactic shock. It's crucial for individuals with a history of severe allergic reactions to carry an epinephrine auto-injector and to be vigilant about food ingredients. While not everyone with the aforementioned sensitivities will experience an allergy to tomatoes, those who do should avoid tomatoes and be aware of their presence in many foods.
