welche allergien gibt es — what can you do yourself?

The question about allergies and self-help is important, but the provided context lacks specific allergy information. Generally, allergies are classified into types (food, pollen, insect venom, drugs). Self-help measures include avoiding triggers, keeping a symptom diary, using antihistamines after consulting a doctor, monitoring pollen counts, and using air purifiers. DNA tests for allergies are not well-validated; they may indicate genetic predispositions but cannot replace a clinical diagnosis. For suspected allergies, an allergist should perform skin prick tests or specific IgE blood tests. Caution: self-treatment can be dangerous, especially if there is risk of anaphylaxis. Evidence for self-help is mostly practice-based.
