Fischallergie

Fischallergie, also known as fish allergy, is an immune system hypersensitivity to proteins found in fish. It is a common food allergy that can cause a range of allergic reactions, from mild symptoms to severe life-threatening anaphylaxis. Fish allergies are distinct from shellfish allergies, and individuals allergic to fish may not necessarily be allergic to shellfish, although cross-reactivity can occur.

The proteins responsible for fish allergy are typically heat-stable, meaning that the allergic reactions can occur even after cooking the fish. Common allergenic fish include salmon, cod, tuna, and haddock. Symptoms of Fischallergie may appear within minutes to a few hours after ingestion and can include skin reactions such as hives or eczema, gastrointestinal symptoms like nausea, vomiting, and diarrhea, respiratory issues such as wheezing or nasal congestion, and, in severe cases, anaphylactic shock.

Diagnosis of fish allergy involves detailed medical history, skin prick tests, specific IgE blood tests, and oral food challenges under medical supervision. Avoidance of all fish species is the primary management strategy, and individuals diagnosed with Fischallergie are advised to read food labels carefully, as fish is a common ingredient in many processed foods. People with fish allergy should also carry emergency medication like epinephrine auto-injectors in case of accidental exposure.

While fish is an important source of omega-3 fatty acids and high-quality protein, individuals with Fischallergie must seek alternative sources to maintain a balanced diet. Currently, there are no curative treatments for fish allergy, making avoidance and emergency preparedness the mainstay of management. Ongoing research continues into potential immunotherapy options aimed at reducing allergen sensitivity.
