The term "allergy load" (a.k.a. "total allergen load") refers to the cumulative exposure to allergens that an individual experiences in their environment. When the allergy load exceeds a person's capacity (a.k.a. "total allergen threshold"), the the person can have allergic reactions, exacerbation of allergic symptoms, or even development of new allergies.
Managing allergy load involves identifying and minimizing exposure to allergens through various strategies, including allergen avoidance, environmental control measures, dietary modifications, and allergen immunotherapy.
Key factors:
-
Environmental Exposures: Examples: pollen, mold, mites, dander, perfume, volatile organic compounds.
-
Dietary Exposures: Examples: dairy, eggs, soy, wheat, peanuts, shellfish. Cross-reactivity between allergens may occur, further increasing the total allergen load.
-
Contact Exposures: Examples: cleaners, detergents, makeup, lotions.
-
Occupational Exposures: Examples: chemicals, dust, fumes, latex, pesticide.
-
Capacity Factors: Genetic predisposition, immune system function, and individual susceptibility to allergens can influence an individual's allergy load capacity and their likelihood of developing allergic diseases
