How do genes and environment contribute to allergies?

Allergies arise from a complex interplay of genetic and environmental factors. Genetic predisposition can make individuals more susceptible to allergic reactions, as certain genes influence the immune system's response to allergens. Environmental factors, such as exposure to pollutants, allergens, and microbial diversity, can trigger or exacerbate these reactions. Together, these influences shape an individual's likelihood of developing allergies throughout their life.
