Introduction to Allergy Symptoms
Allergy symptoms occur when your immune system overreacts to a typically harmless substance (allergen). These reactions can range from mildly annoying to life-threatening. Effective symptom management combines appropriate medications, environmental controls, and lifestyle modifications to reduce suffering and improve quality of life. This cheatsheet provides a comprehensive guide to managing diverse allergy symptoms across different body systems.
Core Concepts in Allergy Symptom Management
The Allergy Response Cycle
- Exposure: Contact with an allergen (inhalation, ingestion, touch, injection)
- Recognition: Immune system identifies the allergen as harmful
- Reaction: Release of chemicals like histamine that cause symptoms
- Manifestation: Appearance of symptoms in target organs/tissues
- Resolution: Symptoms fade as chemicals are metabolized or intervention occurs
Key Symptom Categories
System | Common Symptoms | Typical Triggers |
---|---|---|
Respiratory | Sneezing, congestion, runny nose, coughing, wheezing | Pollen, dust mites, pet dander, mold |
Skin | Hives, itching, rashes, swelling, eczema flares | Foods, medications, insect stings, latex |
Eyes | Redness, itching, tearing, swelling | Pollen, pet dander, dust mites, makeup |
Digestive | Nausea, vomiting, diarrhea, abdominal pain | Food allergens, some medications |
Systemic | Anaphylaxis (multiple system reaction) | Foods, insect venom, medications, latex |
Medication Approaches by Symptom Type
Nasal Symptom Management
Medication Type | Examples | Best For | Usage Tips |
---|---|---|---|
