Allergy risk factors can be categorized into two, the host and the environmental factors. Examples of Host factors are age, heredity, sex, and race. Among them, heredity is the most significant. There are also instances when the occurrences of allergic disorders are not linked with genetic aspects. Allergy attacks can be provoked by environmental factors; allergy causes are the dust, peanuts, and pollens. These factors can be easily identified and allergy treatment can be taken if one is sensitive to pollen.
The threat of allergic sensitization and the development of the allergies differ with age. The peak occurrence of hay fever is highest in children and young adults and the incidence of asthma is highest in children under 10. In comparison to females, males are more likely to develop allergy. However, young female adults are likely to be affected with diseases like asthma. There are also comparisons made in international differences. Results show there is high incidents of allergic diseases in industrialized areas compared to areas, which remain traditional, with rich agriculture.
Since our bodies progress to deal with a certain level of such pathogens, when it is not exposed to this level the immune system will attack harmless antigens, and thus normally benevolent microbial objects, like pollen, will trigger an immune response.
