Why Your Body Overreacts – And What to Do About It
Itchy eyes, a runny nose, hives, swelling, or worse – allergies are your immune system’s misguided attack on harmless substances. They range from mildly annoying to life-threatening, and they are becoming increasingly common. At our practice in Zürich Seefeld, I help patients identify their specific triggers and develop comprehensive management strategies that go beyond antihistamines.
What Are Allergies?
An allergy is an exaggerated immune response to a substance (allergen) that is normally harmless. Your immune system produces IgE antibodies against the allergen, which attach to mast cells. Upon re-exposure, the allergen triggers mast cell degranulation, releasing histamine and other inflammatory mediators that cause allergy symptoms. This response can affect the nose (allergic rhinitis), eyes (allergic conjunctivitis), skin (hives, eczema), lungs (asthma), or the entire body (anaphylaxis).
Common Allergens
Inhalant allergens: Pollen (grass, birch, and other trees are major triggers in Switzerland), house dust mites, animal dander, mould spores.
Food allergens: Nuts, shellfish, eggs, milk, soy, wheat, and increasingly, sesame and other seeds.
Insect venom: Bee and wasp stings can cause severe allergic reactions including anaphylaxis.
Medications: Antibiotics (particularly penicillins), NSAIDs, and many other drugs can trigger allergic reactions.
Contact allergens: Nickel, fragrances, preservatives, latex.
Why Allergies Are Increasing
The prevalence of allergic conditions has risen dramatically over the past decades. Contributing factors include the “hygiene hypothesis” (reduced microbial exposure in early life), changes in gut microbiome composition, environmental pollution, dietary changes, increased indoor living, and climate change extending pollen seasons.
Our Diagnostic Approach
I use skin prick testing and specific IgE blood tests (ImmunoCAP) to identify allergens. Component-resolved diagnostics (molecular allergy testing) can distinguish true allergy from cross-reactivity, which is essential for accurate management. Total IgE, eosinophil count, and tryptase levels provide additional information. For suspected food allergies, I may recommend supervised oral food challenges.
What We Do: Comprehensive Allergy Management
Allergen identification: Precise identification of your triggers through modern diagnostic methods.
Avoidance strategies: Practical guidance on reducing exposure to identified allergens – pollen, dust mites, mould, or food triggers.
Pharmacotherapy: Antihistamines, nasal corticosteroids, leukotriene inhibitors, and eye drops tailored to your symptom profile.
Allergen immunotherapy: For patients with allergic rhinitis, insect venom allergy, or allergic asthma, desensitisation therapy can modify the underlying immune response. I offer both subcutaneous (injection) and sublingual (tablet/drop) immunotherapy.
Gut health optimisation: Emerging evidence supports the role of the microbiome in immune tolerance. Targeted probiotics and gut health strategies may support allergy management.
Emergency preparedness: For patients at risk of anaphylaxis, adrenaline auto-injector prescription, training, and emergency action planning.
Conclusion
Allergies are more than a nuisance – they affect quality of life, productivity, and in severe cases, safety. Modern allergy diagnostics and treatment options, including immunotherapy, offer real solutions. If allergies are controlling your life, book a comprehensive evaluation at our practice in Zürich Seefeld.
