The 28 pages that link to Allergy, each with the reason it gives.

• InflammationCompared with: Allergic reactions can cause inflammation, but they are specifically triggered by allergens.

• AntibodyRelated: Immunoglobulin E antibodies can trigger allergic reactions through mast cells and basophils.

• AutoimmunityCompared with: Allergy targets external substances, unlike autoimmunity's self-directed recognition.

• Immune systemCompared with: It demonstrates how defense can cause harm despite no dangerous infection.

• Infectious diseaseCompared with: Allergic symptoms can resemble infection but arise from hypersensitivity, not pathogens.

• AntihistamineNarrower topic: Antihistamines commonly treat symptoms produced during allergic reactions.

• UrticariaNarrower topic: Allergy can cause acute urticaria, but many cases have no allergic cause.

• AngioedemaNarrower topic: Allergic reactions are one common cause, though many angioedema episodes are not allergic.

• Autoimmune diseaseCompared with: Allergy targets external substances, whereas autoimmune disease targets the body’s own components.

• ImmunologyRelated: Understanding immune hypersensitivity guides allergy testing and treatment.

• Adaptive immune systemCompared with: It shows how antigen-specific responses can cause disease rather than protection.

• ImmunodeficiencyCompared with: Allergy reflects an exaggerated response to particular triggers rather than broadly weakened protection.

• AllergenNarrower topic: An allergen is the trigger within the broader phenomenon of allergy.

• PoisoningCompared with: Allergic reactions can resemble toxic effects but arise from immune recognition rather than dose-dependent toxicity.

• Herbal teaRelated: Herbal ingredients can trigger allergic reactions in susceptible people.

• Nasal polypsRelated: Allergy may accompany nasal symptoms, though it is not the sole cause of most polyps.

• EosinophiliaRelated: Allergic disease can raise eosinophils, but eosinophilia is not specific to allergy.

• Allergy testingNarrower topic: Testing supports an allergy diagnosis only when immune findings fit the clinical reaction.

• Primary immunodeficiencyRelated: Allergic disease may coexist with inherited immune defects but does not itself establish immunodeficiency.

• Spring (season)Related: Spring pollen from trees and grasses triggers seasonal allergic rhinitis.

• InfestationRelated: Mites and insect debris can trigger allergic reactions without directly infecting a person.

• Lymantria disparRelated: Caterpillar hairs and shed material can irritate skin and trigger respiratory symptoms.

• 4-Aminobenzoic acidRelated: PABA-containing products have been associated with allergic contact reactions.

• Charles RichetRelated: Richet’s findings helped establish that immune responses could be harmful as well as protective.

• Flour miteNarrower topic: Flour-mite proteins can act as allergens in sensitized people.

• Immune System DiseasesBroader topic: Allergy is a familiar, often IgE-mediated subset of immune hypersensitivity.

• Immune system phenomenaCompared with: It shows how a response to harmless exposures can become harmful.

• Toxic injuryCompared with: Allergic harm depends on immune recognition, unlike direct toxic injury.
