Ristiallergiat

Ristiallergiat, also known as cross-allergies or co-allergies, occur when a person allergic to one substance also reacts to another substance that has a similar molecular structure. This phenomenon is common in individuals with pollen allergies, where they might also experience reactions to certain fruits, vegetables, or nuts. For example, someone with birch pollen allergy might react to apples, pears, or peaches because the proteins in these foods are similar to those found in birch pollen. Similarly, latex allergy can lead to cross-reactivity with bananas, avocados, and kiwis. The immune system mistakenly identifies the similar proteins in different substances as the same allergen, triggering an allergic response. Symptoms can range from mild itching and swelling in the mouth or throat to more severe reactions like hives, digestive issues, or even anaphylaxis. Identifying ristiallergiat often involves a detailed medical history, skin prick tests, and sometimes blood tests. Management typically involves avoiding the cross-reactive foods or substances, though some individuals may tolerate them when cooked, as heat can alter the protein structure. It's important for individuals with known allergies to discuss the possibility of ristiallergiat with their allergist to ensure proper diagnosis and management.
