Causes & Risk Factors
There are two main factors of allergies and can be categorized into host and environmental factors. Host factors include sex, age, race and hereditary; with hereditary being the most crucial factor. Environmental factors can be exposure to infectious diseases during childhood, dietary and environmental pollution.
Allergies are commonly believed to be caused by immune issues when foreign bodies or allergens enter the body and are detected and appeared to be a threat. The perceived intruder (allergens) triggers the body's defense system to combat this threat.
On initial exposure to the allergens, white blood cells produces antibodies known as IgE antibodies and connect themselves to Mast cells found within the respiratory system, gastrointestinal tract and skin. This initial exposure produces no outward symptoms. On subsequent exposures, the allergens will combine with the IgE antibodies and produces chemicals like histamines. It is these chemicals that cause inflammation and the standard allergic symptoms like sneezing, runny nose, itching, watery eyes, skin rashes and even swelling of certain elements of the body.
