Introduction to Allergies
Allergies are abnormal immune responses to substances (allergens) that are typically harmless to most people. When someone with allergies encounters an allergen, their immune system produces antibodies that identify the allergen as harmful, triggering inflammatory reactions that can affect the skin, sinuses, airways, or digestive system. Understanding allergy prevention is crucial for maintaining quality of life, reducing healthcare costs, and avoiding potentially life-threatening reactions.
Core Allergy Concepts
Types of Allergies
Allergy Type | Common Triggers | Typical Symptoms |
---|---|---|
Respiratory | Pollen, dust mites, pet dander, mold | Sneezing, runny nose, itchy eyes, congestion |
Food | Peanuts, tree nuts, milk, eggs, shellfish, wheat, soy | Hives, swelling, digestive issues, anaphylaxis |
Skin | Latex, metals, chemicals, fragrances | Rashes, itching, eczema, contact dermatitis |
Insect | Bee stings, wasp venom, fire ants | Swelling, pain, itching, anaphylaxis |
Drug | Antibiotics, NSAIDs, anticonvulsants | Rash, hives, organ-specific reactions, anaphylaxis |
Allergy Response Timeline
- Immediate (Type I): Symptoms within minutes to hours (IgE-mediated)
- Delayed (Type IV): Symptoms within 24-72 hours (T-cell mediated)
Prevention Strategies by Allergen Type
